Prompt and accurate monitoring of cardiovascular and accompanying hemodynamic changes is crucial in achieving adequate management of the condition. Advances in technology has availed procedures such as pulse index continuous cardiac output (PiCCO), which can offer precise monitoring of cardiovascular functions and hemodynamic parameters. In this study, PiCCO is evaluated for its potential utility in improving management and clinical outcomes among elderly patients with AMI complicated by CS. AIM To assess whether use of the PiCCO system can improve clinical outcomes in elderly patients with AMI complicated by CS.METHODS Patients from emergency intensive care units (EICU) or coronary care units (CCU) were randomized to receive PiCCO monitoring or not. The APACHE II score, SOFA score, hs-TnI, NT-proBNP, PaO2/FiO2 ratio and lactate levels on day 1, 3 and 7 after treatment were compared. The infusion and urine volume at 0-24 h, 24-48 h and 48-72 h were recorded, as were the cardiac index (CI), extravascular lung water index (EVLWI), intrathoracic blood volume index (ITBVI) and global end diastolic volume index (GEDVI) at similar time intervals. RESULTS Sixty patients with AMI complicated by CS were included in the study. The PiCCO group had a significantly lower APACHE II score, SOFA score, hs-TnI and NT-proBNP levels on day 1, 3 and 7 after treatment. The infusion and urine volume during 0-24 h in the PiCCO group were significantly greater, and this group also showed significantly higher ADL scores. Furthermore, the PiCCO group spent lesser days on vasoactive agents, mechanical ventilation, and had a reduced length of stay in EICU/CCU. Additionally, the CI was significantly higher at 48 h and 72 h in the PiCCO group compared with that at 24 h, and the EVLWI, ITBVI and GEDVI were significantly decreased at 48 h and 72 h. CONCLUSION Applying the PiCCO system could improve the clinical outcomes of elderly patients with AMI complicated by CS.展开更多

Pharmacotherapy was invalid, and subsequent application of atrial pacing reversed the cardiogenic shock. PCI-related injury of sinuatrial nodal artery leading to acute atrial contractility loss, accompanied by atrioventricular junctional arrhythmia, was diagnosed. We recommend that preoperative risk evaluation be required for multi-risk patients. Likewise, emergent measures should to be established in advance. This case reminds us that atrial pacing can be an optimal management technique once cardiogenic shock has occurred.展开更多

The most common etiology of CS is acute myocardial infarction, Here, we report a case of a 42-year-old male who presented with right flank pain, nausea and vomiting initially thought to be nephrolithiasis, which he had a history of but was ultimately diagnosed with CS due to a type II myocardial infarction. This case illustrates the importance of having a broad differential diagnosis especially when a patient＇s vital signs take a drastic turn since this patient initially resembled someone with nephrolithiasis.展开更多

Background: Little is known about prognosis of CS from non-ischemic cardiomyopathy. Methods: Retrospective monocentric study of patients referred to an ICU during 2 years. Results: Despite aggressive management including intra-aortic balloon pump (31%), extra-renal replacement therapy (36%), extra-corporeal life support (8%), and catecholamine infusion (97%), in-hospital mortality was 46%. Toxic CS or CS related to deficiency carried a better outcome (mortality 5%). Post-myocardial infarction or post-cardiac arrest CS was associated with higher mortality. In the multivariate analyses, only SAPS II (OR 1.037;1.013 - 1.056;p = 0.0001), pulmonary hypertension (OR 4.8;1.3 - 17;p = 0.02), extra-renal replacement therapy (OR 2.9;1.3 - 6;p = 0.006), and dobutamine infusion (OR 0.44;0.2 - 0.96;p = 0.04) were significantly associated with in-hospital mortality. Conclusion: Dobutamine infusion was associated with a better outcome. Higher SAPS II, pulmonary hypertension, and extra-renal replacement therapy were associated with increased in-hospital mortality.展开更多

Methods: We recruited 14 consecutive patients with cardiogenic shock (10 men, 69 ± 12 years) and 18 well-matched baseline characteristics without shock (17 men, 64 ± 9 years) undergoing percutaneous coronary intervention (PCI) for an early phase of a first anterior STEMI in whom plasma level of cardiac enzyme was less elevated. We measured systemic and coronary levels of C-reactive protein, interleukin-6, and angiotensin II, and evaluated the relation of those to myocardial tissue-level reperfusion using both angiographic myocardial blush grade from 0 to 3, with the highest grade indicating normal myocardial perfusion, and a resolution of the sum of ST-segment elevation in 12-lead electrocardiogram. Results: In-hospital mortality was 57% in patients with cardiogenic shock and 6% without shock (p = 0.005). Coronary levels of C-reactive protein (9.2 ± 6.9 vs. 1.7 ± 2.1 mg/L, p = 0.001), interleukin-6 (379 ± 137 vs. 24 ± 20 pg/mL, p = 0.003), and angiotensin II (19 ± 10 vs. 10 ± 6 pg/mL, p = 0.010) were extremely higher in patients with shock than without shock. Interleukin-6 and angiotensin II, but not C-reactive protein, revealed higher in coronary levels than in systemic levels. The presence of both myocardial blush grade el reperfusion (p = 0.012). Conclusions: The exaggerated systemic and coronary inflammation, presumably associated with myocardial mal-reperfusion, was presented in patients with a cardiogenic shock complicating first anterior STEMI.展开更多
文摘Aortic stenosis(AS)is one of the most common types of valvular heart disease in older adults,with age being significantly associated with the development of AS.The transcatheter aortic valve replacement(TAVR)procedure,since it was first performed in 2002,has emerged as a preferred treatment option for patients who are at intermediate to high surgical risk due to advanced age or medical comorbidities.Older adults with severe AS may present with acute decompensated heart failure leading to cardiogenic shock(CS).Among patients 65 years and older with AS presenting for TAVR,4.1%were reportedly in acute CS.Regardless of etiology,mortality from CS itself is high(30%−50%)and increases with advancing age.TAVR for these patients could provide a definite treatment for both AS and CS.There is still limited evidence regarding the safety and efficacy of TAVR in this population,but recent studies are promising,with successful procedural results and a good recovery rate after the procedure.However,particularly for older adults,there are other factors that clinicians should consider during pre-and post-procedural status,such as patient’s goals,frailty,polypharmacy,dementia,or delirium.In this article,we reviewed current studies regarding TAVR for older adults with AS and CS,the reason for comprehensive geriatric assessment,and the introduction of appropriate geriatric assessment tools based on the Age-Friendly 4Ms framework that cardiologists can adopt in real-world practice.

文摘BACKGROUND Data on adsorptive extracorporeal membrane oxygenation(ECMO)(combined with HA380 hemoperfusion column)on the inflammatory factors in patients with cardiogenic shock(CS)remains limited.AIM To investigate the effects of adsorptive ECMO on the inflammatory factors in patients with CS.METHODS A retrospective analysis was performed on 81 patients with CS caused by acute myocardial infarction,fulminant myocarditis,or cardiac surgery who required venoarterial ECMO support at TEDA International Cardiovascular Hospital from December 2020 to December 2024.Patients were divided into the conventional ECMO group(42 cases)and the adsorptive ECMO group(ECMO combined with hemoperfusion,39 cases).The adsorptive ECMO group received 2 columns of HA380 initiation on the first day(the first column connected within 2 hours of ECMO and the second after 12 hours of ECMO),followed by 1 column each day,with each column used for 4–6 hours,totaling 24–30 hours of treatment.Baseline data were compared between the two groups:Inflammatory factor levels(at 0,6,12,24,48,and 72 hours after ECMO or hemoperfusion initiation);ECMO support duration;successful weaning rate;continuous renal replacement therapy(CRRT)utilization;Sequential Organ Failure Assessment(SOFA)score;Vasoactive-Inotropic Score(VIS);systemic inflammatory response syndrome(SIRS)incidence;and in-hospital survival and 30-/90-day survival after discharge.RESULTS The adsorptive ECMO group showed significantly lower levels of C-reactive protein,interleukin(IL)-6,tumor necrosis factor(TNF)-α,and lactate from 6 to 72 hours compared with the conventional ECMO group(all P<0.05),with IL-6 decreasing by 94.4%and tumour necrosis factor alpha by 70.1%from baseline at 72 hours.The adsorptive ECMO group had a significantly shorter ECMO duration[114.0(75.0–139.0)hours vs 135.0(73.0–199.3)hours,P=0.032];higher successful weaning rate(66.7%vs 42.9%,P=0.032);a trend toward lower CRRT utilization(54.8%vs 38.5%,P=0.070);lower post-weaning SOFA score[7(6–8)vs 9(8–10),P<0.001];significantly reduced VIS(8.4±1.3 vs 9.8±1.6,P<0.001);and a trend toward lower SIRS incidence(10.3%vs 26.2%,P=0.065).There were no significant differences in complications,in-hospital survival(64.1%vs 52.4%,P=0.285);or 30-/90-day survival between the two groups(all P>0.05).CONCLUSION Adsorptive ECMO efficiently clears IL-6 and TNF-α,significantly improving ECMO weaning success rate and hemodynamics.However,it has no significant impact on survival,and its efficacy requires validation through prospective studies.
文摘Background Acute Myocardial Infarction(AMI)is a critical and commonly encountered condition in the field of cardiovascular medicine.When AMI is complicated by cardiogenic shock(CS),the clinical scenario becomes significantly more complex and perilous,with a marked increase in patient mortality.Currently,traditional thera-peutic approaches such as intra-aortic balloon pumping(IABP)have demonstrated efficacy in improving myocardi-al perfusion and hemodynamics.However,the supportive capacity of IABP is limited in patients with severe heart failure.In recent years,extracorporeal membrane oxygenation(ECMO),as an advanced extracorporeal circulatory support technology,has been increasingly utilized in clinical practice,offering a novel therapeutic option for pa-tients with severe heart failure.This study aimed to investigate the clinical efficacy of combining IABP and ECMO in patients with AMI complicated by CS,evaluating its impact on myocardial injury,hemodynamic stability,and clinical outcomes.Methods This study retrospectively analyzed the clinical data of 52 patients with AMI compli-cated by CS admitted to our hospital between May 2023 and May 2024.Based on the treatment methods,the pa-tients were divided into an ECMO group(n=26)and a non-ECMO group(n=26).Post-treatment comparisons were made between the two groups regarding myocardial injury markers such as cardiac troponin I,lactate,and creatine kinase-MB,hemodynamic parameters such as mean arterial pressure,cardiac output,and central venous pressure,and the incidence of complications such as acute kidney injury,bleeding,infection.The primary endpoint of this study was the post-treatment mortality rate and the incidence of complications.Secondary endpoints included changes in myocardial injury markers[cardiac troponin I(cTnI),lactic acid(LAC),creatine kinase isoenzymes(CK-MB)]and improvements in hemodynamic parameters[mean arterial pressure(MAP),cardiac output(CO),central venous pressure(CVP)].The results of multivariate regression analyses were used to explore the incidence of EC-MO complications.Results After treatment,the levels of myocardial injury markers such as cTnI,LAC,and CK-MB in ECMO group were significantly lower than non-ECMO group(P<0.05);MAP and CO in ECMO group were significantly higher than non-ECMO group,while CVP was significantly lower(P<0.05);the mortality rate and the incidence of complications in ECMO group were lower than non-ECMO group(P<0.05).Further multivariate re-gression analysis showed that age,smoking,hyperlipidaemia and diabetes could affect the incidence of ECMO complications(P<0.05).Conclusions The combined use of IABP and ECMO exhibits substantial therapeutic benefits,including the mitigation of myocardial injury,enhancement of hemodynamic stability,and improvement in clinical prognosis among patients with AMI complicated by CS.Clinicians applying ECMO therapy should pay particular attention to older patients or those with concomitant diabetes mellitus or hyperlipidemia,as they might re-quire more intensive monitoring and prophylactic measures to mitigate the occurrence of complications.
文摘Cardiogenic shock(CS)is a life-threatening syndrome characterized by peripheral hypoperfusion and organ dysfunction caused by primary heart disease.Venoarterial extracorporeal membrane oxygenation(VA-ECMO)is a temporary mechanical circulatory support device for CS,used in cases of profound shock,biventricular failure,respiratory failure,and cardiac arrest that require urgent maximal support.While VA-ECMO provides effective tissue perfusion and ensures oxygen supply to organs,it is also associated with severe complications,among which acute kidney injury(AKI)is one of the most common and serious.To date,no comprehensive review has been conducted on the pathophysiology,influencing factors,and treatment of AKI associated with VA-ECMO.This paper aims to elaborate on the pathophysiological mechanisms,influencing factors,and treatment options for AKI in patients with CS undergoing VA-ECMO,providing clinical and nursing references.
文摘AIM:To assess the impact of percutaneous cardiac support in cardiogenic shock(CS)complicating acute myocardial infarction(AMI),treated with percutaneous coronary intervention.METHODS:We selected all of the studies published from January 1st,1997 to May 15 st,2015 that compared the following percutaneous mechanical support in patients with CS due to AMI undergoing myocardial revascularization:(1)intra-aortic balloon pump(IABP)vs Medical therapy;(2)percutaneous left ventricular assist devices(PLVADs)vs IABP;(3)complete extracorporeal life support with extracorporeal membrane oxygenation(ECMO)plus IABP vs IABP alone;and(4)ECMO plus IABP vs ECMO alone,in patients with AMI and CS undergoing myocardial revascularization.We evaluated the impact of the support devices on primary and secondary endpoints.Primary endpoint was the inhospital mortality due to any cause during the same hospital stay and secondary endpoint late mortality at 6-12 moof follow-up.RESULTS:One thousand two hundred and seventytwo studies met the initial screening criteria.After detailed review,only 30 were selected.There were 6 eligible randomized controlled trials and 24 eligible observational studies totaling 15799 patients.We found that the inhospital mortality was:(1)significantly higher with IABP support vs medical therapy(RR=+15%,P=0.0002);(2)was higher,although not significantly,with PLVADs compared to IABP(RR=+14%,P=0.21);and(3)significantly lower in patients treated with ECMO plus IABP vs IABP(RR=-44%,P=0.0008)or ECMO(RR=-20%,P=0.006)alone.In addition,Trial Sequential Analysis showed that in the comparison of IABP vs medical therapy,the sample size was adequate to demonstrate a significant increase in risk due to IABP.CONCLUSION:Inhospital mortality was significantly higher with IABP vs medical therapy.PLVADs did not reduce early mortality.ECMO plus IABP significantly reduced inhospital mortality compared to IABP.
文摘BACKGROUND Cardiogenic shock (CS) secondary to acute myocardial infarction (AMI) complicates management of the condition, and often leads to poor prognosis. Prompt and accurate monitoring of cardiovascular and accompanying hemodynamic changes is crucial in achieving adequate management of the condition. Advances in technology has availed procedures such as pulse index continuous cardiac output (PiCCO), which can offer precise monitoring of cardiovascular functions and hemodynamic parameters. In this study, PiCCO is evaluated for its potential utility in improving management and clinical outcomes among elderly patients with AMI complicated by CS. AIM To assess whether use of the PiCCO system can improve clinical outcomes in elderly patients with AMI complicated by CS.METHODS Patients from emergency intensive care units (EICU) or coronary care units (CCU) were randomized to receive PiCCO monitoring or not. The APACHE II score, SOFA score, hs-TnI, NT-proBNP, PaO2/FiO2 ratio and lactate levels on day 1, 3 and 7 after treatment were compared. The infusion and urine volume at 0-24 h, 24-48 h and 48-72 h were recorded, as were the cardiac index (CI), extravascular lung water index (EVLWI), intrathoracic blood volume index (ITBVI) and global end diastolic volume index (GEDVI) at similar time intervals. RESULTS Sixty patients with AMI complicated by CS were included in the study. The PiCCO group had a significantly lower APACHE II score, SOFA score, hs-TnI and NT-proBNP levels on day 1, 3 and 7 after treatment. The infusion and urine volume during 0-24 h in the PiCCO group were significantly greater, and this group also showed significantly higher ADL scores. Furthermore, the PiCCO group spent lesser days on vasoactive agents, mechanical ventilation, and had a reduced length of stay in EICU/CCU. Additionally, the CI was significantly higher at 48 h and 72 h in the PiCCO group compared with that at 24 h, and the EVLWI, ITBVI and GEDVI were significantly decreased at 48 h and 72 h. CONCLUSION Applying the PiCCO system could improve the clinical outcomes of elderly patients with AMI complicated by CS.

文摘Background The prognostic role of diabetes mellitus(DM)in elderly patients with myocardial infarction-related cardiogenic shock(MI-CS)remains controversial.Little information exists about the impact of intensive cardiac care unit(ICCU)and revascularization on outcomes of elderly patients with MI-CS.We aimed to assess the prognostic impact of DM according to age in patients with MI-CS,and to analyze the impact ICCU management and revascularization on in-hospital mortality in MI-CS patients at older ages.Methods Discharge episodes with diagnosis of CS associated with MI were selected from the Spanish National Health System’s Basic Data Set.Centers were classified according to their availability of ICCU.Main outcome measured was in-hospital mortality.Results A total of 23,590 episodes of MI-CS were identified,of whom 12,447(52.8%)were in patients aged≥75 years.The impact of DM on in-hospital mortality was different among age subgroups.While in younger patients,DM was associated to a higher mortality risk(0.52 vs.0.47,OR=1.12,95%CI:1.06–1.18,χ^2<0.001),this association became non-significant in older patients(0.76 vs.0.81,χ^2=0.09).Adjusted mortality rate of MI-CS aged≥75 years was lower in patients admitted to hospitals with ICCU(adjusted mortality rate:74.2%vs.77.7%,P<0.001)and in patients undergoing revascularization(74.9%vs.77.3%,P<0.001).Conclusions Prognostic impact of DM in patients with MI-CS was different according to age,with a significantly lower impact at older ages.The availability of ICCU and revascularization were associated with better outcomes in these complex patients.
文摘BACKGROUND Intravenous thrombolysis is an important treatment for cerebral infarction.However,it is difficult to achieve good results if the patient is complicated with anterior circulation macrovascular occlusion.In addition,the vascular recanalization rate is low,so mechanical thrombectomy,that is,bridging therapy,is needed AIM To investigate the efficacy and safety of bridging therapy and direct mechanical thrombectomy in the treatment of cardiogenic cerebral infarction with anterior circulation macrovascular occlusion.METHODS Ninety-six patients in our hospital with cardiogenic cerebral infarction with anterior circulation macrovascular occlusion from January 2017 to July 2020 were divided into a direct thrombectomy group(n=48)and a bridging group(n=48).Direct mechanical thrombectomy was performed in the direct thrombectomy group,and bridging therapy was used in the bridging treatment group.Comparisons were performed for the treatment data of the two groups(from admission to imaging examination,from admission to arterial puncture,from arterial puncture to vascular recanalization,and from admission to vascular recanalization),vascular recanalization rate,National Institutes of Health Stroke Scale(NIHSS)and Glasgow Coma Scale(GCS)scores before and after treatment,prognosis and incidence of adverse events.RESULTS In the direct thrombectomy group,the time from admission to imaging examination was 24.32±8.61 min,from admission to arterial puncture was 95.56±37.55 min,from arterial puncture to vascular recanalization was 54.29±21.38 min,and from admission to revascularization was 156.88±45.51 min,and the corresponding times in the bridging treatment group were 25.38±9.33 min,100.45±39.30 min,58.14±25.56 min,and 161.23±51.15 min;there were no significant differences between groups(P=0.564,0.535,0.426,and 0.661,respectively).There was no significant difference in the recanalization rate between the direct thrombectomy group(79.17%)and the bridging group(75.00%)(P=0.627).There were no significant differences between the direct thrombectomy group(16.69±4.91 and 12.12±2.07)and the bridging group(7.13±1.23) and(14.40±0.59)in preoperative NIHSS score and GCS score(P=0.200 and 0.203,respectively).After the operation,the NIHSS scores in both groups were lower than those before the operation,and the GCS scores were higher than those before the operation.There was no significant difference in NIHSS and GCS scores between the direct thrombectomy group(6.91±1.10 and 14.19±0.65)and the bridging group(7.13±1.23 and 14.40±0.59)(P=0.358 and 0.101,respectively).There was no significant difference in the proportion of patients who achieved a good prognosis between the direct thrombectomy group(52.08%)and the bridging group(50.008%)(P=0.838).There was no significant difference in the incidence of adverse events between the direct thrombectomy group(6.25%)and the bridging group(8.33%)(P=0.913).CONCLUSION Bridging therapy and direct mechanical thrombectomy can safely treat cardiogenic cerebral infarction with anterior circulation macrovascular occlusion,achieve good vascular recanalization effects and prognoses,and improve the neurological function of patients.
文摘Cardioembolic stroke,referred to as cardiogenic stroke,is a clinical syndrome in which emboli from the heart pass through the circulatory system and cause cerebral artery embolism and corresponding brain dysfunction.Compared to other subtypes of ischemic stroke,cardiogenic stroke presents with more etiologies,greater severity,worse prognosis,and a higher recurrence rate.In this minireview,we provide new insights into the etiological classification,diagnostic methods,and interventions of cardiogenic stroke.

文摘OBJECTIVE Shenfu injection(SFI)is an effective treatment of cardiogenic shock,the pathology of the central link was microcirculation disturbance.However,whether the microcirculation status of the early-and mid-stage of cardiogenic shock has any difference is unclear.This study aimed to observe the effect of SFI on the microcirculatory disturbance in mesentery for early-and mid-stage of cardiogenic shock rat.METHODS The early-and mid-stage model of cardiogenic shock was established by ligating the ending or root of left anterior descending coronary arteries(LADCA).The rats were randomly divided into 9 groups,ie control group,early-stage model group,mid-stage model group,3 early medicated groups and 3 mid medicated groups(the dosage was 1,3.33,10 mL·kg^(-1) SFI for cardiogenic shock rats of early-and mid-stage,respectively).Parameters in mesenteric microcirculation,such as velocity of RBCs in venules,diameters of venules,the count of leukocyte adhesion and vascular permeability which calculated by FITC-dextran leakage were observed through an GeneandiM2 inverted intravital microscope and high-speed video camera system.RESULTS The cardiogenic shock induced by ligating the LADCA resulted in a number of responses in microcirculation,including a significant increase in the counts of adhesive leukocytes,narrowing of the vascular diameter,decrease in the velocity of RBCs and dextran efflux.All of the above parameters for early-stage cardiogenic shock rats were attenuated by the treatment with SFI,especially the dosage of 10 mL·kg^(-1).While SFI had no apparent time-effect on the vascular diameter and vascular permeability in mesentery for mid-stage cardiogenic shock rats.CONCLUSION The microcirculation status of the early-and mid-stage of cardiogenic shock rats were quite different.The efficacy of early treatment with SFI was more obvious than the mid administration,which could provide experimental and theoretical basis for the patients with cardiogenic shock in an earlier time.
文摘Background Extra-corporeal membranous oxygenation (ECMO)and intra-aortic balloon pumping (IABP) are widely used in patients with severe circulatory failure. The decision to initiate ECMO and IABP on optimal occasion in postcardiotomy cardiogenic shock (PCS) remains controversial in the absence of guidelines.
文摘An 82-year-old female patient undergoing cardiogenic shock caused by atrioventficular junctional rhythm immediately after percutaneous coronary intervention （PCI） is described. Pharmacotherapy was invalid, and subsequent application of atrial pacing reversed the cardiogenic shock. PCI-related injury of sinuatrial nodal artery leading to acute atrial contractility loss, accompanied by atrioventricular junctional arrhythmia, was diagnosed. We recommend that preoperative risk evaluation be required for multi-risk patients. Likewise, emergent measures should to be established in advance. This case reminds us that atrial pacing can be an optimal management technique once cardiogenic shock has occurred.
文摘Acute myocardial infarction(AMI)with left ventricular(LV)dysfunction patients,the most common cause of cardiogenic shock(CS),have acutely deteriorating hemodynamic status.The frequent use of vasopressor and inotropic pharmacologic interventions along with mechanical circulatory support(MCS)in these patients necessitates invasive hemodynamic monitoring.After the pivotal Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness trial failed to show a significant improvement in clinical outcomes in shock patients managed with a pulmonary artery catheter(PAC),the use of PAC has become less popular in clinical practice.In this review,we summarize currently available literature to summarize the indications,clinical relevance,and recommendations for use of PAC in the setting of AMI-CS.
文摘INTRODUCTION The presentation of cardiogenic shock （CS） is usually straightforward, and includes hypotension, absence of hypovolemia, and clinical signs of poor tissue perfusion such as oliguria, cyanosis, cool extremities and altered mentation. The most common etiology of CS is acute myocardial infarction, Here, we report a case of a 42-year-old male who presented with right flank pain, nausea and vomiting initially thought to be nephrolithiasis, which he had a history of but was ultimately diagnosed with CS due to a type II myocardial infarction. This case illustrates the importance of having a broad differential diagnosis especially when a patient＇s vital signs take a drastic turn since this patient initially resembled someone with nephrolithiasis.
文摘Cardiogenic shock in the setting of acute myocardial infarction(AMI)carries significant morbidity and mortality,despite advances in pharmacological,mechanical and reperfusion therapies.Studies suggest that there is evidence of sex disparities in the risk profile,management,and outcomes of cardiogenic shock complicating AMI.Compared with men,women tend to have more comorbidities,greater variability in symptom presentation and are less likely to receive timely revascularization and mechanical circulatory support.These factors might explain why women tend to have worse outcomes.In this review,we highlight sex-based differences in the prevalence,management,and outcomes of cardiogenic shock due to AMI,and discuss potential ways to mitigate them.
文摘The adverse outcomes of a ventricular heart failure(left,right or biventricular)caused by cardiogenic shock are aggravated by lung oedema and organ mal perfusion.Despite advances in medical sciences,revascularisation and mechanical hemodynamic support have proved ineffective in reducing the mortality rate in such patients.A thorough study of the data available about cardio-vascular diseases reveals that the application of conventional methods of treatment are least helpful to practically restore normal functions of heart when it experiences end-stage systolic ventricular failure.Thus,to overcome the challenges and find alternatives to address this issue,percutaneous ventricular support devices/machines were designed and successfully introduced.These devices have revolutionized the treatment of ventricular heart failures and are now in use all over the world.In this review paper a newer mechanical circulatory support(MCS)device,Impella,has been discussed and compared with a few other devices like Intra-aortic Balloon Pump(IABP),Extracorporeal Circulation(ECLS)and Veno-arterial Extracorporeal Membrane Oxygenation(VA-ECMO).This article studies the challenges being faced during the treatment of cardiogenic shock,and thoroughly discusses the use and effectiveness of Impella Cardiac Axial Pump in each emergency.It can be said that mechanical circulatory support(MCS)device use during percutaneous coronary intervention(PCI)should be individualized based on multiple factors with a recommended use in patients with the greatest potential benefit and a relatively low risk of device-related complications.The current literature suggests that the outcomes of use of Impella and other mechanical circulatory support devices like IABP and VA-ECMO are comparable.Though there seem to be a few advantages of Impella over the others,sufficiently powered,multi-centric,randomised control trials are needed to establish its superiority.
文摘BACKGROUND Temporary transvenous pacing through the coronary sinus is a novel approach rarely used in treating unstable bradycardia.This modality could provide cardiac pacing while achieving better ventricular synchrony.We present a case who received cardiac pacing through the coronary sinus and provide a summary of evidence in the current literature.CASE SUMMARY A 55-year-old woman with a history of advanced heart failure was admitted to the rehabilitation ward after a recent stroke.During hospitalization,she had paroxysmal atrial fibrillation with rapid ventricular response resulting from fluid overload.While atrial fibrillation was spontaneously reversed to sinus rhythm after diuresis,she developed multiple episodes of polymorphic ventricular tachycardia along with sinus bradycardia and prolonged QTc interval.She became hypotensive despite appropriate medical management.Pacing through her implantable cardioverter-defibrillator was attempted but worsened her hypotension.Ventricular dyssynchrony was suspected.Temporary transvenous atrial pacing through the coronary sinus was performed,which stabilized her blood pressure and improved end-organ perfusion.A permanent biventricular pacemaker was later implanted,and she was safely discharged to a nursing home.CONCLUSION Temporary transvenous pacing through the coronary sinus,a novel approach to treat unstable bradycardia,may reduce ventricular dyssynchrony.
文摘Cardiomyopahty is one of complications of thyrotoxicosis. About 6% of thyrotoxic patients develop heart failure, but less than 1% of the patients progress dilated cardiomyopathy with systolic left ventricular dysthnction.
文摘Objective: Prognostic analysis of 249 patients admitted for cardiogenic shock (CS) of various origins. Background: Little is known about prognosis of CS from non-ischemic cardiomyopathy. Methods: Retrospective monocentric study of patients referred to an ICU during 2 years. Results: Despite aggressive management including intra-aortic balloon pump (31%), extra-renal replacement therapy (36%), extra-corporeal life support (8%), and catecholamine infusion (97%), in-hospital mortality was 46%. Toxic CS or CS related to deficiency carried a better outcome (mortality 5%). Post-myocardial infarction or post-cardiac arrest CS was associated with higher mortality. In the multivariate analyses, only SAPS II (OR 1.037;1.013 - 1.056;p = 0.0001), pulmonary hypertension (OR 4.8;1.3 - 17;p = 0.02), extra-renal replacement therapy (OR 2.9;1.3 - 6;p = 0.006), and dobutamine infusion (OR 0.44;0.2 - 0.96;p = 0.04) were significantly associated with in-hospital mortality. Conclusion: Dobutamine infusion was associated with a better outcome. Higher SAPS II, pulmonary hypertension, and extra-renal replacement therapy were associated with increased in-hospital mortality.
文摘We characterized the degree of systemic and coronary inflammation and the impact of those on clinical state in patients with a cardiogenic shock complicating first anterior ST-segment elevation myocardial infarction (STEMI). Methods: We recruited 14 consecutive patients with cardiogenic shock (10 men, 69 ± 12 years) and 18 well-matched baseline characteristics without shock (17 men, 64 ± 9 years) undergoing percutaneous coronary intervention (PCI) for an early phase of a first anterior STEMI in whom plasma level of cardiac enzyme was less elevated. We measured systemic and coronary levels of C-reactive protein, interleukin-6, and angiotensin II, and evaluated the relation of those to myocardial tissue-level reperfusion using both angiographic myocardial blush grade from 0 to 3, with the highest grade indicating normal myocardial perfusion, and a resolution of the sum of ST-segment elevation in 12-lead electrocardiogram. Results: In-hospital mortality was 57% in patients with cardiogenic shock and 6% without shock (p = 0.005). Coronary levels of C-reactive protein (9.2 ± 6.9 vs. 1.7 ± 2.1 mg/L, p = 0.001), interleukin-6 (379 ± 137 vs. 24 ± 20 pg/mL, p = 0.003), and angiotensin II (19 ± 10 vs. 10 ± 6 pg/mL, p = 0.010) were extremely higher in patients with shock than without shock. Interleukin-6 and angiotensin II, but not C-reactive protein, revealed higher in coronary levels than in systemic levels. The presence of both myocardial blush grade el reperfusion (p = 0.012). Conclusions: The exaggerated systemic and coronary inflammation, presumably associated with myocardial mal-reperfusion, was presented in patients with a cardiogenic shock complicating first anterior STEMI.
