文摘Myocardial infarction with nonobstructive coronary arteries is a unique presentation of acute coronary syndrome occurring in patients without significant coronary artery disease.Its pathophysiology involves atherosclerotic and nonatherosclerotic mechanisms such as plaque erosion,coronary microvascular dysfunction,vasospasm,spontaneous coronary artery dissection,autoimmune and inflammatory diseases,and myocardial oxygen supply-demand imbalance.A systematic approach to diagnosis is needed due to the diverse range of underlying causes.Cardiac troponins confirm the myocardial injury and coronary angiography rules out significant obstruction.Cardiac magnetic resonance imaging differentiates ischemic from nonischemic causes,and additional investigations,such as intravascular ultrasound,optical coherence tomography,and provocative testing,play a role in identifying the etiology to guide management strategies.Atherosclerotic cases require antiplatelet therapy and statins,vasospastic cases respond to calcium channel blockers,spontaneous coronary artery dissection is typically managed conservatively,and coronary microvascular dysfunction may require vasodilators.Lifestyle modifications and cardiac rehabilitation are essential for improving outcomes.The prognosis of patients experiencing recurrent events despite treatment is uncertain,but long-term outcomes depend on the etiology,highlighting the need for personalized management.Future research should focus on refining diagnostic protocols and identifying optimal therapeutic strategies.Randomized controlled trials are necessary to establish evidence-based treatments for different subtypes of myocardial infarction with nonobstructive coronary arteries.

文摘Recent clinical trials have demonstrated a protective effect in using traditional Chinese medicine Tongxinluo(TXL)capsule to treat atherosclerosis.However,clinical evidence of the effects of TXL treatment on coronary plaque vulnerability is unavailable.In response,we developed this study to investigate the hypothesis that on the basis of statin therapy,treatment with TXL capsule may stabilize coronary lesions in patients with acute coronary syndrome(ACS).The TXL-CAP study was an investigator-initiated,randomized,double-blind clinical trial conducted across 18 medical centers in China.Patients with ACS aging from 18 to 80 years old who had a non-intervened coronary target lesion with a fibrous cap thickness(FCT)<100μm and lipid arc>90°as defined by optical coherence tomography(OCT)were recruited.A total of 220 patients who met the selection criteria but did not meet the exclusion criteria will be finally recruited and randomized to receive treatment with TXL(n=110)or placebo(n=110)for a duration of 12 months.The primary endpoint was the difference in the minimum FCT of the coronary target lesion between TXL and placebo groups at the end of the 12-month follow-up.Secondary endpoints included:(1)changes of the maximum lipid arc and length of the target plaque,and the percentage of lipid,fibrous,and calcified plaques at the end of the12-month period;(2)the incidence of composite cardiovascular events and coronary revascularization within the 12 months;(3)changes in the grade and scores of the angina pectoris as assessed using the Canadian Cardiovascular Society(CCS)grading system and Seattle angina questionnaire(SAQ)score,respectively;and(4)changes in hs-CRP serum levels.The results of the TXLCAP trial will provide additional clinical data for revealing whether TXL capsules stabilizes coronary vulnerable plaques in Chinese ACS patients.
文摘BACKGROUND Giant coronary artery aneurysms(CAA),entailing thrombosis,myocardial infarction,and sudden death,are the most severe and life-threatening complications of Kawasaki disease(KD).Giant aneurysms rarely regress and can later transform into stenoses.Data on dynamic follow-up are scarce in the literature.AIM To evaluate clinical features and long-term outcomes of giant CAA in children with KD.METHODS A single-center retrospective study included data from patients with KD and giant CAA in the Irkutsk region(2012-2023).CAA criteria according to the American Heart Association guidelines of 2017 were used:(1)Dilated coronary artery with diameter Z-score>2 standard deviations(SD)but<2.5 SD;(2)Small CAA with Z-score>2.5 SD but<5 SD;(3)Medium CAA with Z-score>5 SD but<10 SD;and(4)Giant CAA with Z-score>10 SD or≥8 mm.RESULTS The mean age of children with coronary dilatation/aneurysms was 2.5 years,and the male-to-female ratio was 3:1.Patients with giant/medium CAA had symptoms of cerebral dysfunction more often compared with children with moderate(Z-score<5 SD but>2.0 SD)coronary dilatation(62.0%vs 21.0%,P=0.019).Major cardiovascular events(myocardial infarction,coronary artery bypass grafting,acute coronary syndrome,ischemic cardiomyopathy,left ventricular aneurysm,and giant extracardiac aneurysm)occurred in 55.5%of patients who had giant CAA.At follow-up the complete regression of giant/medium CAA was observed in 58.0%and partial regression in 42.0%after a mean of 2.3 and 5.5 years,respectively.All thrombi detected by echocardiography,CT,and angiography in giant/medium CAA disappeared between 1 year and 5 years(mean:15 months).All patients survived.CONCLUSION Risk factors for giant CAA were male sex,early age,and cerebral dysfunction.Complete regression of giant coronary aneurysms occurred in 58.0%of patients after follow-up of 2.3 years.

文摘OBJECTIVE To evaluate the safety and effectiveness of robot-assisted percutaneous coronary intervention(R-PCI)compared to traditional manual percutaneous coronary intervention(M-PCI).METHODS This prospective,multicenter,randomized controlled,non-inferior clinical trial enrolled patients with coronary heart disease who met the inclusion criteria and had indications for elective percutaneous coronary intervention.Participants were randomly assigned to either the R-PCI group or the M-PCI group.Primary endpoints were clinical and technical success rates.Clinical success was defined as visually estimated residual post-percutaneous coronary intervention stenosis<30% with no 30-day major adverse cardiac events.Technical success in the R-PCI group was defined as successful completion of percutaneous coronary intervention using the ETcath200 robot-assisted system,without conversion to M-PCI in the event of a guidewire or balloon/stent catheter that was unable to cross the vessel or was poorly supported by the catheter.Secondary endpoints included total procedure time,percutaneous coronary intervention procedure time,fluoroscopy time,contrast volume,operator radiation exposure,air kerma,and dose-area product.RESULTS The trial enrolled 152 patients(R-PCI:73 patients,M-PCI:79 patients).Lesions were predominantly B2/C type(73.6%).Both groups achieved 100% clinical success rate.No major adverse cardiac events occurred during the 30-day follow-up.The R-PCI group had a technical success rate of 100%.The R-PCI group had longer total procedure and fluoroscopy times,but lower operator radiation exposure.The percutaneous coronary intervention procedure time,contrast volume,air kerma,and dose-area product were similar between the two groups.CONCLUSIONS For certain complex lesions,performing percutaneous coronary intervention using the ETcath200 robot-assisted system is safe and effective and does not result in conversion to M-PCI.
文摘BACKGROUND 2D-echocardiography(2DE)has been the primary imaging modality in children with Kawasaki disease(KD)to assess coronary arteries.AIM To report the presence and implications of incidental congenital coronary artery anomalies that had been misinterpreted as coronary artery abnormalities(CAAs)on 2DE.METHODS Records of children diagnosed with KD,who underwent computed tomography coronary angiography(CTCA)at our center between 2013-2023 were reviewed.We identified 3 children with congenital coronary artery anomalies in this cohort on CTCA.Findings of CTCA and 2DE were compared in these 3 children.RESULTS Of the 241 patients with KD who underwent CTCA,3(1.24%)had congenital coronary artery anomalies on CTCA detected incidentally.In all 3 patients,baseline 2DE had identified CAAs.CTCA was then performed for detailed evaluation as per our unit protocol.One(11-year-boy)amongst the 3 patients had complete KD,while the other two(3.3-year-boy;4-month-girl)had incomplete KD.CTCA revealed separate origins of left anterior descending artery and left circumflex from left sinus[misinterpreted as dilated left main coronary artery(LCA)on 2DE],single coronary artery(interpreted as dilated LCA on 2DE)and dilated right coronary artery on 2DE in case of anomalous origin of LCA from the main pulmonary artery.The latter one was subsequently operated upon.CONCLUSION CTCA is essential for detailed assessment of coronary arteries in children with KD especially in cases where there is suspicion of congenital coronary artery anomalies.Relying solely on 2DE may not be sufficient in such cases,and findings from CTCA can significantly impact therapeutic decision-making.
文摘Background Coronary atherectomy is used to treat severely calcified coronary artery lesions which are more frequent with increasing age,but its impact in older adults has not been sufficiently examined.Methods We compared adults≥18 years old who underwent coronary atherectomy during inpatient PCI in 2016–2023 from the Vizient Clinical Data Base and compared outcomes in younger(<65 years),youngest-old(65–74 years),middle-old(75–84 years),and oldest-old(≥85 years)adults.Primary outcome was in-hospital mortality,and secondary outcomes included postprocedural complications.Results Among 47,337 patients who underwent coronary atherectomy,19,862(42.0%)were younger adults and 27,475(58.0%)were older adults,including 13,583 youngest-old,10,206 middle-old,and 3,686 oldest-old adults.Compared with younger adults,youngest-old adults had higher mortality(adjusted odds ratio[aOR]=1.37,P<0.001),ischemic stroke(aOR=1.35,P=0.005),gastrointestinal hemorrhage(GIH)(aOR=1.44,P<0.001),acute kidney injury(AKI)(aOR=1.43,P<0.001),tamponade(aOR=1.86,P<0.001),and pericardiocentesis(aOR=2.32,P<0.001).Middle-old adults had higher mortality(aOR=1.80,P<0.001),GIH(aOR=1.42,P=0.002),AKI(aOR=1.63,P<0.001),tamponade(aOR=2.52,P<0.001),and pericardiocentesis(aOR=3.13,P<0.001).Oldest-old adults had the highest odds for mortality(aOR=2.03,P<0.001),GIH(aOR=1.48,P=0.016),AKI(aOR=2.26,P<0.001),tamponade(aOR=3.86,P<0.001),and pericardiocentesis(aOR=4.21,P<0.001).There was a significant interaction(P-interaction=0.035)between atherectomy and age groups with regard to the odds of in-hospital mortality.Conclusions In this large claims-based study,in-hospital mortality,GIH,AKI,tamponade,and pericardiocentesis were higher in older adults compared with younger adults,in a stepwise manner by age group.

文摘BACKGROUND Our understanding of the correlation between postdischarge cancer and mortality in patients with coronary artery disease(CAD)remains incomplete.The aim of this study was to investigate the relationships between postdischarge cancers and all-cause mortality and cardiovascular mortality in CAD patients.METHODS In this retrospective cohort study,25%of CAD patients without prior cancer history who underwent coronary artery angiography between January 1,2011 and December 31,2015,were randomly enrolled using SPSS 26.0.Patients were monitored for the incidence of postdischarge cancer,which was defined as cancer diagnosed after the index hospitalization,survival status and cause of death.Cox regression analysis was used to explore the association between postdischarge cancer and all-cause mortality and cardiovascular mortality in CAD patients.RESULTS A total of 4085 patients were included in the final analysis.During a median follow-up period of 8 years,174 patients(4.3%)developed postdischarge cancer,and 343 patients(8.4%)died.A total of 173 patients died from cardiovascular diseases.Postdischarge cancer was associated with increased all-cause mortality risk(HR=2.653,95%CI:1.727–4.076,P<0.001)and cardiovascular mortality risk(HR=2.756,95%CI:1.470–5.167,P=0.002).Postdischarge lung cancer(HR=5.497,95%CI:2.922–10.343,P<0.001)and gastrointestinal cancer(HR=1.984,95%CI:1.049–3.750,P=0.035)were associated with all-cause mortality in CAD patients.Postdischarge lung cancer was significantly associated with cardiovascular death in CAD patients(HR=4.979,95%CI:2.114–11.728,P<0.001),and cardiovascular death was not significantly correlated with gastrointestinal cancer or other types of cancer.CONCLUSIONS Postdischarge cancer was associated with all-cause mortality and cardiovascular mortality in CAD patients.Compared with other cancers,postdischarge lung cancer had a more significant effect on all-cause mortality and cardiovascular mortality in CAD patients.
文摘Percutaneous coronary intervention(PCI),as an essential treatment for coronary artery disease,has significantly improved the prognosis of patients with large coronary artery lesions.However,some patients continue to experience myocar-dial ischemic symptoms post-procedure,largely due to coronary microvascular dysfunction(CMD).The pathophysiological mechanisms of CMD are complex and involve endothelial dysfunction,microvascular remodeling,reperfusion in-jury,and metabolic abnormalities.Moreover,components of metabolic syndrome,including obesity,hyperglycemia,hypertension,and dyslipidemia,exacerbate the occurrence and progression of CMD through multiple pathways.This review systematically summarizes the latest research advan-cements in CMD after PCI,including its pathogenesis,diagnostic techniques,management strategies,and future research directions.For diagnosis,invasive techniques such as coronary flow reserve and the index of microcirculatory resistance,as well as non-invasive imaging modalities(positron emission tomography and cardiac magnetic reso-nance),provide tools for early CMD detection.In terms of management,a multi-level intervention strategy is emphasized,incorporating lifestyle modifications(diet,exercise,and weight control),pharmacotherapy(vasodilators,hypoglycemic agents,statins,and metabolic modulators),traditional Chinese medicine,and specialized treatments(enhanced external counterpulsation,metabolic surgery,and lipoprotein apheresis).However,challenges remain in CMD treatment,including limitations in diagnostic tools and the lack of personalized treatment strategies.Future research should focus on the complex interactions between CMD and metabolic risks,aiming to optimize diagnostic and therapeutic strate-gies to improve the long-term prognosis of patients post-PCI.
文摘Background Percutaneous coronary intervention(PCI)is a widely utilized revascularization technique for coronary artery disease(CAD).While clinical and biomarker-based prognostic tools are standard for predicting outcomes,there is growing interest in sarcopenia as a marker of frailty and its potential role in long-term prognosis.The prognostic value of the psoas muscle index(PMI),a sarcopenia metric,remains underexplored in PCI populations regarding long term survival.Methods This single-center retrospective cohort study evaluated 177 patients undergoing PCI from 2015 to 2019.PMI was calculated from computed tomography(CT)imaging at the L3 vertebral level using the formula:(left psoas area+right psoas area)/height2 and expressed in cm2/m2.Sarcopenia was defined as the lowest sex-specific PMI quartile.Primary outcomes included 5-year all-cause mortality and 3-point major adverse cardiovascular events(MACE:non-fatal myocardial infarction,ischemic stroke,and cardiac death).Binary linear regression and Cox proportional hazards models were utilized to determine associations between PMI and outcomes Results Sarcopenic patients exhibited significantly higher 5-year all-cause mortality compared to non-sarcopenic counterparts(64.4%vs.35.6%,P<0.001),while no significant difference was observed in 3-point MACE incidence(55.6%vs.51.4%,P=0.520).Sarcopenia was independently associated with all-cause mortality on binary logistic regression(OR=3.49;95%CI:1.69–7.19;P=0.0007),but not MACE(OR=1.00;95%CI:0.50–1.98;P=0.99).In a multivariable Cox regression model,sarcopenia was associated with increased hazard of mortality(HR=1.60;95%CI:0.96–2.66;P=0.071),though this did not reach statistical significance.Kaplan-Meier analysis demonstrated significantly reduced survival among sarcopenic patients(χ2=6.13,P=0.0133).Conclusions PMI is a significant independent predictor of 5-year all-cause mortality in PCI patients,underscoring the prognostic importance of assessing skeletal muscle mass in this population.

文摘BACKGROUND As the global population ages,the number of elderly patients with acute coronary syndrome(ACS)rises.However,prognostic assessment tools for elderly patients with ACS remain lacking,particularly in the Chinese population.This study aimed to develop and validate a nomogram to predict 2-year major adverse cardiovascular and cerebrovascular events(MACCE)in elderly Chinese patients with ACS.METHODS A retrospective analysis was conducted using two independent cohorts of ACS patients aged≥65 years who underwent percutaneous coronary intervention:the derivation cohort(n=1674)and the validation cohort(n=2333).Candidate predictors were selected using multivariable Cox proportional hazards regression and the Akaike information criterion.A final nomogram incorporating ten variables was constructed.Model performance was evaluated in terms of discrimination[concordance index(C-index)and area under the receiver operating characteristic curve(AUC)]and calibration(calibration plots).RESULTS The 2-year incidence of MACCE was 12.5%(n=210)in the derivation cohort and 15.6%(n=364)in the validation cohort.The nomogram demonstrated good discrimination,with C-index values of 0.727 and 0.661 and AUCs of 0.723 and 0.699 in the derivation cohort and the validation cohort,respectively;significantly outperforming the GRACE risk score(P<0.001).Calibration plots showed good agreement between the predicted and observed outcomes.Patients classified as the high-risk group by the nomogram had a significantly higher MACCE incidence compared to that of the low-risk group(log-rank P<0.001).CONCLUSIONS This newly developed nomogram provides a reliable tool for individualized prediction of the 2-year MACCE risk in elderly Chinese patients with ACS who underwent percutaneous coronary intervention.It outperformed the GRACE score in both discrimmination and calibration and may help improve clinical decision-making and personalized risk stratification in this vulnerable population.
文摘BACKGROUND Postmenopausal women face an increased risk of cardiovascular disease(CVD)due to estrogen withdrawal,which exacerbates traditional cardiovascular risk factors such as dyslipidemia,glucose intolerance,and hypertension.Coronary Artery Calcium Score(CACS),a well-established marker of subclinical atherosclerosis,has emerged as a key predictor of adverse cardiovascular events.Despite the recognized association between menopause and heightened CVD risk,there remains a paucity of literature exploring the specific role of menopause in influencing CACS and its implications for cardiovascular morbidity and morta lity.AIM To examine the interplay between menopause,CACS,and cardiovascular health by synthesizing existing literature.METHODS A comprehensive literature search was conducted using PubMed and Google Scholar,focusing on studies that analyzed CACS in postmenopausal women,including the influence of factors such as hormone therapy,Triglyceride-Glucose index,bone mineral density,lipid metabolism,and type-1 diabetes.Data extraction and synthesis emphasized key patterns,metabolic influences,and potential mechanisms driving coronary calcification in menopause.RESULTS Findings suggest that menopause contributes to increased CACS through multiple pathways,including altered lipid metabolism,insulin resistance,and arterial stiffness.Additionally,premature menopause is associated with higher CACS and elevated CVD risk.While hormone replacement therapy(HRT)appears to have a protective effect against coronary calcification,further research is needed to clarify its long-term benefits and risks.CONCLUSION We introduce a novel framework combining CACS with metabolic and hormonal markers,and discuss estrogendriven mechanisms and HRT considerations in postmenopausal cardiovascular risk.This review underscores the need for targeted cardiovascular risk assessment in postmenopausal women,integrating CACS with other metabolic markers to improve early detection and prevention of CVD in this high-risk population.

文摘BACKGROUND Understanding the type and extent of coronary artery involvement in patients with acute type A aortic dissection(ATAAD)is vital for surgical planning.The Neri classification has been proposed as a guide for surgical strategies,however,its prognostic impact on postoperative mortality rates remains understudied in large-scale cohorts.METHODS We reviewed 600 ATAAD patients who underwent surgery and coronary computed tomography angiography from 2016 to 2020 at Fuwai Hospital,National Center for Cardiovascular Diseases,Chinese Academy of Medical Sciences and Peking Union Medical College,Beijing,China.Patients were classified based on the Neri classification system:no coronary artery involvement,type A(ostial involvement),type B(dissection in coronary body),and type C(circumferential detachment or complete avulsion).The primary endpoint was 30-day mortality.RESULTS Overall,28.3%of the patients had coronary artery involvement,with Neri type A,Neri type B,and Neri type C accounting for 13.3%,11.2%,and 3.8%,respectively.The right coronary artery was more frequently involved(25.3%)than the left coronary artery(8.0%).In the unadjusted analysis,patients with coronary artery involvement exhibited a numerically higher 30-day mortality compared to those without(5.3%vs.2.3%)(OR=2.35,95%CI:0.94–5.88,P=0.07),though this difference did not reach statistical significance.However,multivariable adjustment revealed significant association(adjusted OR=3.71,95%CI:1.05–13.13,P=0.04).Interestingly,after additional adjustment for coronary artery bypass grafting,the impact of coronary artery involvement on 30-day mortality no longer remained statistically significant(adjusted OR=3.13,95%CI:0.85–11.58,P=0.09).The 1-year mortality was higher in those with coronary artery involvement,but this significant association disappeared after adjusting for potential confounding variables.Furthermore,no significant difference in 30-day and 1-year mortality were observed among patients with different Neri classifications.CONCLUSIONS In patients with ATAAD who undergo surgery,the presence of coronary artery involvement is significantly associated with an increased risk of 30-day mortality.Proactive coronary artery bypass grafting may potentially mitigate the adverse impact of coronary artery involvement on 30-day mortality.

文摘Kounis syndrome(KS)is a rare but clinically significant condition characterized by the simultaneous occurrence of acute coronary syndrome(ACS)and allergic reactions,which can develop in patients with either normal or diseased coronary arteries.[1,2]The condition is typically triggered by various allergens including medications(particularly contrast media),environmental factors,or food exposures,with symptom onset usually occurring within one hour of exposure.
文摘BACKGROUND Coronary artery bypass grafting(CABG)and percutaneous coronary intervention(PCI)are well-established treatments for multivessel coronary artery disease(CAD),a condition where multiple heart arteries are narrowed.A newer approach,fractional flow reserve(FFR)-guided PCI,uses a specialized measurement to select which artery blockages to treat,aiming to enhance patient outcomes.Despite its adoption,the comparative effectiveness of FFR-guided PCI vs CABG remains unclear,particularly regarding key health outcomes such as survival,heart-related complications,and the need for further procedures.AIM To evaluate the safety and effectiveness of FFR-guided PCI compared to CABG in patients with multivessel CAD.METHODS This meta-analysis followed standard reporting guidelines and included randomized controlled trials(RCTs)comparing FFR-guided PCI with CABG in patients with multivessel CAD.We searched medical databases,including PubMed,EMBASE,ScienceDirect,and ClinicalTrials.gov,from their start to May 2025.We calculated combined risk ratios(RRs)with 95%confidence intervals(95%CIs)to analyze the data.RESULTS Three RCTs were analyzed.There was no notable difference in all-cause mortality between FFR-guided PCI and CABG(RR=1.01,95%CI:0.78-1.31,P=0.93).However,FFR-guided PCI showed higher rates of major adverse cardiac events(MACEs;RR=1.30,95%CI:1.11-1.52,P=0.001),myocardial infarction(RR=1.49,95%CI:1.11-2.01,P=0.009),and repeat revascularization(RR=2.25,95%CI:1.78-2.85,P<0.00001).Stroke rates were comparable between the two treatments(RR=0.80,95%CI:0.54-1.20,P=0.28).CONCLUSION FFR-guided PCI and CABG have similar rates of all-cause mortality and stroke in patients with multivessel CAD.However,CABG results in fewer MACEs,myocardial infarctions,and repeat procedures.

文摘Pericoronary adipose tissue(PCAT)plays an important role in the pathogenesis and progression of cardiovascular diseases due to its bidirectional communication with the coronary artery wall.In recent years,PCAT parameters measured using coronary computed tomography have emerged as potential noninvasive imaging biomarkers for quantifying coronary artery inflammation,with significant clinical value in the early detection,disease progression assessment,treatment efficacy evaluation,and prognosis prediction of cardiovascular diseases.Furthermore,new technologies such as PCAT radiomics analysis have broadened its potential applications in evaluating coronary plaque vulnerability,predicting cardiovascular events,and improving risk stratification.This review discusses recent advances in PCAT research,focusing on its role in coronary artery disease risk identification and inflammation monitoring,and aims to offer imaging-based insights to support its future clinical use in cardiovascular disease management.

文摘BACKGROUND With rising angiography costs and risks,we explored whether a 5-minute femoral ultrasound can predict patients that actually require angiography.AIM To detect associations between atherosclerosis of peripheral arteries and coronary stenosis in patients with coronary heart disease(CHD).METHODS The study included a total of 218 patients(63±10.9 years of age;54%male)with CHD subjected to coronary angiography and routine diagnostic assessment,including ultrasound imaging to assess the extent of peripheral atherosclerotic lesions.Receiver operating characteristic analysis and binomial logistic regression were used to detect the associations.RESULTS We demonstrated for the first time that the presence of atherosclerotic plaque with≥70%stenosis in femoral arteries was associated with significant coronary stenosis,with 93%sensitivity and 90%specificity,and thus can be used as an additional diagnostic marker for coronary stenosis.The data indicated associations between femoral artery atherosclerosis and atherosclerotic lesions of coronary arteries,with a high correlation coefficient r=0.8(P<0.05).The presence of an atherosclerotic plaque in the femoral arteries with≥30% or≥70%stenosis was associated with a 30-or 70-fold higher odds ratio of coronary stenosis,respectively.CONCLUSION For resource-limited clinics,our findings suggest skipping carotids-femoral ultrasound alone may suffice to rule out severe CHD.Ultrasound imaging femoral artery atherosclerosis provides a simplified approach for patient stratification.
文摘BACKGROUND Listening to music has been shown to reduce pain and anxiety before,during,and after invasive coronary procedures.AIM To perform a systematic review and meta-analysis to explore the effect of therapeutic use of music on both,perioperative and postoperative outcomes of invasive coronary procedures.METHODS An exhaustive literature search of 3 electronic databases(MEDLINE,Scopus,Cochrane CENTRAL)was conducted from inception until 10th December 2023.The results of our analyses are presented as standard mean difference(SMD)or weighted mean difference,with 95%CI and pooled using a random effects model.A P value<0.05 was considered significant in all cases.RESULTS From 21 studies,2141 participants were included in our analysis.The pooled analysis demonstrated that music listening significantly improves post-procedural pain(SMD=-0.78,95%CI:-1.34 to-0.23;P=0.006),anxiety(SMD=-0.86,95%CI:-1.43 to-0.29;P=0.003),heart rate[mean difference(MD)=-3.38,95%CI:-5.51 to-1.25;P=0.002],and systolic blood pressure(MD=-5.89,95%CI:-9.75 to-2.02;P=0.003).There was no significant improvement in diastolic blood pressure(MD=-3.22,95%CI:-6.58 to 0.14;P=0.06)or respiratory rate(MD=-0.97,95%CI:-1.98 to 0.03;P=0.06).CONCLUSION Music listening can be used in healthcare settings for patients undergoing invasive coronary procedures to reduce anxiety levels and improve their physiological parameters.
文摘Background Quantitative flow ratio(QFR)based lesion selection for percutaneous coronary intervention(PCI)treatment has shown clinical benefits in terms of reduced risk for myocardial infarction and repeat revascularization.Whether this benefit is consistent across different age groups still needs further investigation.Methods In this prespecified subgroup study of FAVORⅢChina trial,we compared long-term clinical outcomes between QFR-guided and angiography-guided PCI among different age groups among 3825 enrolled subjects.The primary endpoint was major adverse cardiac events(MACEs),a composite of all-cause death,myocardial infarction,and ischemia-driven revascularization.Results Of the 3825 patients,1717(44.9%)were aged≥65 years.At baseline,patients≥65 had higher rates of hypertension,hyperlipidaemia,stroke history(P<0.0001),and peripheral vascular disease(P=0.024)and had higher SYNTAX scores(P=0.0095).Compared with standard angiography guidance,the QFR-guided strategy consistently reduced the 1-year(≥65 years,6.04%vs.9.19%,HR=0.65,95%CI:0.46–0.92;<65 years,5.53%vs.8.43%,HR=0.65,95%CI:0.47–0.91)and 3-year MACE rates in both age groups(≥65 years,11.8%vs.15.2%,HR:0.75,95%CI:0.58–0.98;<65 years,9.5%vs.14.6%,HR=0.63;95%CI:0.49–0.81),without a significant interaction(Pinteraction=0.99).Within the QFR-guided group,the 3-year MACE rate in patients with deferred vessels was numerically greater in patients aged≥65 years than in those aged<65 years(8.3%vs.3.0%,P=0.10).Conclusions Although with higher rate of comorbidities and more complex coronary anatomy,the long-term benefit of the QFR-guided PCI strategy remained consistent in patients≥65 years,compared with those<65 years.
文摘BACKGROUND The persistent burden of cardiovascular(CV)disease in the United States requires innovative and cost-effective prognostic markers that can be relied upon.AIM To provide insights into how adiponectin can predict all-cause mortality and major adverse CV events(MACE)in patients with coronary artery disease(CAD)and to determine the prognostic value of adiponectin in predicting all-cause mortality and MACE in patients with stable CAD.METHODS We conducted a systematic search on PubMed,Scopus,and Google Scholar to find relevant studies published through June 2023 evaluating the long-term prognostic role of adiponectin in patients with stable CAD.Using a random effects model with 95%CI,we estimated the odds ratio(OR)while assessing heterogeneity through I^(2)statistics.To ensure robustness,we performed a sensitivity analysis using the leave-one-out approach.RESULTS After screening,we included five prospective studies involving 3225 patients who were followed up for a median duration of 3.8 years.Within the study population,prevalent risk factors included hypertension,diabetes,hyperlipidemia,and smoking.The commonly prescribed medications were angiotensin-converting enzyme inhibitors,beta blockers,and statins.The combined adjusted OR for all-cause mortality was found to be 2.51(95%CI:1.36–4.62),showing heterogeneity(I^(2)=65.51%,P=0.03).On the other hand,the combined adjusted OR for MACE was determined to be 1.04(95%CI:1.02–1.06)with no significant heterogeneity observed(I^(2)=0%,P=0.68).Through a sensitivity analysis,it was discovered that none of the studies significantly impacted the overall results of the meta-analysis,thus indicating their robustness.CONCLUSION Higher levels of adiponectin were found to be associated with an increased risk of long-term mortality and MACE in patients with CAD,which highlights its potential as a cost-effective marker for risk assessment and guiding treatment strategies.Further research on the role of adiponectin could greatly influence decision-making and resource allocation in CV care.
