When acute fluid collection persists for 4 - 6 weeks and is encapsulated by a fibrous wall, it is classified as a pancreatic pseudocyst. While PPC is generally asymptomatic in many patients, it can manifest with persistent abdominal pain, dyspepsia, intra-cystic infection, and potentially lead to gastrointestinal obstruction in some cases. Although smaller PPCs may resolve spontaneously, larger PPCs tend to be refractory to absorption and often necessitate surgical intervention to prevent complications such as intracystic hemorrhage. Objective: To explore the efficacy of percutaneous catheterization with negative pressure in the treatment of large pancreatic pseudocysts. Methods: The cases of large pancreatic pseudocysts treated in our hospital from 2004 to 2022 were retrospectively collected, and the general condition, operation time, drainage time, feeding time, postoperative complications, hospital stay, cost and follow-up of the patients were analyzed. Results: A total of 132 patients with large pancreatic pseudocysts were collected. The average operation time was 32.4 ± 2.1 min;The retention time of the drainage tube was 30 ± 1.8 days in the percutaneous negative pressure drainage group;The postoperative feeding time was no fasting after local anesthesia drainage;Postoperative complications (bleeding, infection, pancreatic leakage, recurrence, anastomotic leakage, etc.): Two of the 132 patients had recurrent cysts, which were cured by re-puncture and negative pressure drainage. The length of hospital stay was 6 ± 1.1 days;The cost was 11,200 ± 1300 yuan;Follow-up: The follow-up time ranged from 1 to 3 years, and the patients had no discomfort. Conclusion: Percutaneous catheterization and negative pressure drainage can effectively treat large pancreatic pseudocysts. Compared with other treatment methods, it is simple and effective, the postoperative recovery of patients is faster, the physical damage is less, the hospital stay is shorter, and the cost is lower.展开更多

For patients with kidney stones, especially large, multiple or staghorn stones, percutaneous nephrolithotomy (PCNL) is a preferred treatment method. Infection-related complications after percutaneous nephrolithotomy include transient fever, systemic inflammatory response syndrome, and urinary sepsis, especially urinary sepsis, which are considered to be common causes of death after percutaneous nephrolithotomy. Therefore, early identification and timely intervention of biomarkers can reduce the incidence and mortality of postoperative sepsis, as well as the length of hospital stay and hospitalization costs. This article reviews the biomarkers for early identification of urinary tract infection after PCNL, such as traditional inflammatory indicators, new inflammatory indicators, and composite inflammatory indicators.展开更多

文摘BACKGROUND Antithrombotic strategies after percutaneous coronary interventions(PCI)in elderly patients on oral anticoagulant therapy(OAT)are debated due to the balance between ischemic and bleeding risks.Recent guidelines recommend early transitioning from triple antithrombotic therapy to dual antithrombotic therapy,but there are limited data on elderly patients.METHODS We performed a post-hoc age-specific analysis of the PERSEO Registry population aimed to compare clinical features,therapeutic strategies,and outcomes of individuals aged≥80 years and<80 years who were on OAT and underwent PCI with stent.The primary endpoint was net adverse clinical events at 1-year follow-up.Secondary endpoints included major adverse cardiac and cerebral events(MACCE),major bleeding[Bleeding Academic Research Consortium(BARC)type 3–5],and clinically relevant bleeding(BARC type 2-5).RESULTS Among the 1234 patients enrolled,31%of patients were aged≥80 years(84±3 years,76% males).Compared to younger patients,elderly patients had higher rates of comorbidities such as hypertension,anaemia or chronic kidney disease,and atrial fibrillation was the leading indication for OAT.Elderly patients were more often discharged on dual antithrombotic therapy(23%)compared to younger patients(13%)(P<0.0001).They experienced higher net adverse clinical events(38%vs.21%,P<0.001),MACCE(24%vs.12%,P<0.001),as well as higher bleeding rates.Specifically,rates of major bleeding(9%vs.6%,P=0.026),and clinically relevant bleeding(21%vs.12%,P<0.001)were significantly higher in elderly patients.CONCLUSIONS Elderly patients on OAT undergoing PCI are a particular frail population with higher risk of MACCE and bleeding compared to younger patients despite a less aggressive antithrombotic therapy.
文摘BACKGROUND Simultaneous acute ischemic stroke(AIS)and myocardial infarction(cardio-cerebral ischemic attack)have rarely been reported in the literature.Currently,no clear evidence-based guidelines or clinical trials exist to determine the optimal therapeutic strategy for these patients.CASE SUMMARY We present the case of a 27-year-old Chinese man who simultaneously experie-nced acute concomitant cerebrocardiac infarction(CCI)and painless ST-elevation myocardial infarction.The patient was successfully treated with elective percu-taneous coronary intervention(PCI)after receiving urgent systemic thrombolysis at the standard dose for AIS.CONCLUSION Urgent thrombolysis followed by elective PCI was an appropriate strategy for the management of simultaneous CCI.
文摘Bcakground: Pancreatic pseudocyst (PPC) is a common complication arising from acute or chronic pancreatitis, trauma, or pancreatic duct obstruction. When acute fluid collection persists for 4 - 6 weeks and is encapsulated by a fibrous wall, it is classified as a pancreatic pseudocyst. While PPC is generally asymptomatic in many patients, it can manifest with persistent abdominal pain, dyspepsia, intra-cystic infection, and potentially lead to gastrointestinal obstruction in some cases. Although smaller PPCs may resolve spontaneously, larger PPCs tend to be refractory to absorption and often necessitate surgical intervention to prevent complications such as intracystic hemorrhage. Objective: To explore the efficacy of percutaneous catheterization with negative pressure in the treatment of large pancreatic pseudocysts. Methods: The cases of large pancreatic pseudocysts treated in our hospital from 2004 to 2022 were retrospectively collected, and the general condition, operation time, drainage time, feeding time, postoperative complications, hospital stay, cost and follow-up of the patients were analyzed. Results: A total of 132 patients with large pancreatic pseudocysts were collected. The average operation time was 32.4 ± 2.1 min;The retention time of the drainage tube was 30 ± 1.8 days in the percutaneous negative pressure drainage group;The postoperative feeding time was no fasting after local anesthesia drainage;Postoperative complications (bleeding, infection, pancreatic leakage, recurrence, anastomotic leakage, etc.): Two of the 132 patients had recurrent cysts, which were cured by re-puncture and negative pressure drainage. The length of hospital stay was 6 ± 1.1 days;The cost was 11,200 ± 1300 yuan;Follow-up: The follow-up time ranged from 1 to 3 years, and the patients had no discomfort. Conclusion: Percutaneous catheterization and negative pressure drainage can effectively treat large pancreatic pseudocysts. Compared with other treatment methods, it is simple and effective, the postoperative recovery of patients is faster, the physical damage is less, the hospital stay is shorter, and the cost is lower.
文摘While cystolitholapaxy for bladder stones is commonly performed using a transurethral approach,large or complex stone burdens in patients with complex lower urinary tract anatomy may make this inefficient or infeasible.Percutaneous cystolitholapaxy is a safe,effective,minimally invasive alternative for diverse indications,including patients with benign prostatic hyperplasia,urethral stricture disease,closed bladder neck,continent catheterized channel,or other urinary diversion.In this article,we review the indications for and advantages of percutaneous cystolitholapaxy and describe our step-by-step technique for this procedure,including representative imaging and favored equipment.We also discuss preoperative and postoperative considerations,management of potential complications,strategies to optimize clinical outcomes and patient safety,and comparisons with transurethral approaches.Finally,we report outcomes from our institutional series of percutaneous cystolitholapaxy cases to highlight the safety and efficacy of the procedure.
文摘BACKGROUND Flat bone metastases are common in patients with advanced cancers,often resulting in severe pain,limited mobility,and reduced quality of life(QOL).Traditional treatment options,such as radiotherapy or systemic therapies,often fail to provide sufficient pain relief or improve functional outcomes in these patients.Microwave ablation(MWA)offers advantages,such as shorter pro-cedure times and larger ablation zones,while percutaneous osteoplasty(PO)enhances bone stability and prevents pathological fractures.Despite these be-nefits,the combination of these techniques for treating flat bone metastases re-mains underexplored.AIM To evaluate the efficacy and safety of C-arm computed tomography(CT)-guided MWA combined with PO for managing painful flat bone metastases,focusing on pain relief,functional improvement,and QOL enhancement.METHODS A total of 45 patients with refractory moderate-to-severe pain resulting from flat bone metastases who underwent C-arm CT-guided MWA combined with PO between January 2015 and January 2021 were included.The efficacy of the pro-cedure was assessed by changes in the visual analog scale(VAS),Oswestry disability index(ODI),and QOL,as well as the occurrence of complications.Tumor response was evaluated using RECIST v1.1 and mRECIST criteria,with overall response rate(ORR)and disease control rate(DCR)as the primary end-points.RESULTS No serious complications were observed in any of the patients.A significant reduction in VAS and ODI was noted at 1 week,1 month,and 3 months post-procedure.A marked improvement in QOL was observed at all follow-up points.Bone cement extravasation was observed in 10 patients;however,none exhibited significant clinical symptoms.Based on RECIST v1.1,the ORR was 26.7%and the DCR was 88.9%.The mRECIST evaluation revealed a higher ORR of 51.1%and DCR of 88.9%.CONCLUSION C-arm CT-guided MWA with PO provides a dependable and effective strategy for managing flat bone metastases.It demonstrates significant pain relief,improved functional outcomes,and enhanced QOL.This treatment combination also shows promising tumor response rates with a low complication profile.

文摘BACKGROUND Choledochal cyst is a rare biliary tract disorder with five subtypes categorized based on the anatomical location of cystic dilatation.Type IV(which affects the intrahepatic and extrahepatic ducts)is the most common subtype in adults.Its clinical manifestations are diverse and the disease can potentially become malignant.Currently,the mainstay treatment is surgical excision which is used as a definitive treatment to prevent complications and avoid carcinogenesis.However,the surgical operation for giant choledochal cysts is technically challenging.CASE SUMMARY Here,we present a case of a giant choledochal cyst in an 18-year-old female.The diagnosis of patient was confirmed through magnetic resonance cholangiopancreatography.The patient developed acute cholangitis,and was treated with percutaneous transhepatic cholangial drainage to alleviate symptoms.The final treatment approach was cyst excision followed by Roux-en-Y hepaticojejunostomy,which successfully achieved excellent postoperative recovery.CONCLUSION Ultrasonography and magnetic resonance cholangiopancreatography can effectively diagnose choledochal cysts.Combined percutaneous transhepatic cholangial drainage surgery for giant choledochal cysts is safe and effective.
文摘Ultrasound-guided percutaneous thermal ablation has gained popularity as treatment for malignant hepatic tumors.It was first introduced as ablation therapy for hepatocellular carcinoma and cirrhosis comorbidity.Recently,this technique has also been used in the treatment of intrahepatic cholangiocarcinoma for patients who are not eligible for surgical resection.There are several types of thermal ablation techniques.Radiofrequency ablation and microwave ablation are two common methods that induce necrosis of the lesions.Irreversible electroporation is a relatively new non-thermal technique and is suitable in cases where thermal ablation would be ineffective or dangerous(e.g.,malignant tumors close to vascular or biliary structures).Irreversible electroporation can induce tumoral necrosis without damage to vascular and biliary structures.The aim of this minireview was to describe the safety,efficacy,and clinical indications of these techniques in the treatment of patients with intrahepatic cholangiocarcinoma who are ineligible for surgery.
文摘BACKGROUND Severe acute cholangitis is a potentially life-threatening disease in low-middle income countries(LMIC).Due to limited endoscopic services,these patients mostly undergo percutaneous transhepatic biliary drainage(PTBD).Studies from developed countries reported more complications with PTBD as compared with endoscopic retrograde cholangiopancreatography(ERCP).AIM To compare safety,therapeutic success,and survival among the PTBD and ERCP procedure in severe cholangitis in LMIC.METHODS A retrospective study was conducted in the Aga Khan University Hospital from January 2017 to December 2023.All patients who had severe acute cholangitis and underwent ERCP or PTBD were included.Patients were followed for complications,procedure success,and mortality.Data was gathered through an electronic medical record system and analyzed usingχ²and two sample t-tests.RESULTS A total of 33 patients were recruited,consisting of 12 females and 21 males with a mean age of 61 years.Among these participants,12 patients underwent ERCP,and the remaining 21 patients underwent PTBD.Therapeutic success was seen more in the ERCP group[11/12(97.1%)]than in the PTBD group[12/21 patients(57.1%)].Post-procedure complications were seen in both groups;however,more were observed in the PTBD cohort with a significant P value of 0.02.There were no mortalities among the patients who underwent ERCP while 5(23.8%)mortalities were seen in the PTBD group.CONCLUSION Fewer post-procedure complications and deaths were observed after ERCP than after PTBD,laying the foundation for large prospective studies and shifting the local paradigm of acute cholangitis treatment in LMICs.
文摘BACKGROUND Gas-containing pseudocysts rarely cause of lumbar radiculopathy.This report describes successful treatment of a gas-containing pseudocyst using percutaneous transforaminal endoscopy.CASE SUMMARY A 48-year-old man presented with severe pain and numbness in his right leg,which worsened upon walking or weight bearing.Computed tomography and magnetic resonance imaging revealed a gas-containing cyst compressing the left L5 nerve root at the L4-5 level.The pseudocyst was successfully removed using a percutaneous transforaminal endoscopic discectomy.Vivid and clear endoscopic imaging of the pseudocysts was performed intraoperatively.The patient experienced immediate pain relief and was discharged one day after the operation.The patient returned to work.Moreover,numbness in the right leg returned to normal within 6 months.At the one-year follow-up,there was no symptoms recurrence.CONCLUSION Transforaminal endoscopy offers excellent surgical visualization and facilitates meticulous operative manipulation,making it a minimally invasive approach for treating gas-containing pseudocysts in the intervertebral foramen.
文摘BACKGROUND It is well known that in case of high initial strictures of bile ducts surgical treatment is associated with a high risk of damage to the hepatoduodenal ligament elements,often involved in rough scarring,and with a significant risk of stricture recurrence.AIM To compare the long-term outcomes of different surgical treatment options for patients with high-grade benign biliary strictures.METHODS From 2012 to 2022,193 patients were treated at the A.V.Vishnevsky Surgical Center.All of them had different levels of strictures according to Bismuth-Strasberg classification:Type E1-2 in 32 patients,type E3-99,type E4-62.123 patients underwent open reconstructive interventions,70 percutaneous endobiliary interventions.RESULTS Long-term results were available for 192(99%)patients with a follow-up of 4.7±1.6 years after reconstructive surgery;3.0±1.4 years after percutaneous interventions.Excellent and good results(according to Terblanche classification)were achieved in 35%(42/122)of patients after open reconstructive surgery and in 13%(9/70)of patients after percutaneous transhepatic interventions(P-value<0.05).CONCLUSION Technically,the most difficult bile duct strictures for reconstructive and percutaneous transhepatic interventions with a high recurrence rate are Bismuth-Strasberg type E4 and E5.The comparative analysis of long-term results of percutaneous and open procedures showed a statistically significant advantage of percutaneous procedures compared to open reconstructive procedures.
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Objectives This study aimed to develop a hospital-community-family trinity cardiac rehabilitation(CR)intervention program and assess its’effects on patients with acute myocardial infarction(AMI)after percutaneous coronary intervention(PCI).Methods Between April 2022 and April 2023,patients who had experienced AMI after PCI were enrolled.These patients were randomly assigned to an intervention group(IG)or a control group(CG)in equal numbers.The CG received standard CR,while the IG participated in the advanced trinity CR program in addition to the standard CR.Key parameters measured included the anaerobic threshold(AT),maximum oxygen uptake(V̇O2max),maximum exercise load(MEL),metabolic equivalent(MET),left ventricular ejection fraction(LVEF),left ventricular end-systolic volume(LVESV),left ventricular end-diastolic volume(LVEDV),and quality of life(measured by the SF-36).These were assessed pre-intervention and at 3,6,9,and 12 months post-intervention.SPSS.26 was employed for data analysis,with statistical methods such as repeated measures analysis of variance(ANOVA),Chi-square tests,and independent sample t-tests.Results A total of 110 patients completed the intervention,55 in each group.There was no significant difference in the scores of all indicators between the two groups before intervention(P>0.05).However,at 3,6,9 and 12 months after intervention,the scores of AT,VO2max,MEL,MET,LVEDV,LVESV,LVEF,and quality of life in the intervention group were higher than those in the control group,there was statistical significance at four-time points,group,time,and interaction effect(P<0.05).Conclusions The hospital-community-family trinity CR intervention program developted in this study significantly improved exercise endurance,cardiac function,and quality of life in patients with AMI after PCI.

文摘Urinary calculi are a common and frequently occurring disease in urology. For patients with kidney stones, especially large, multiple or staghorn stones, percutaneous nephrolithotomy (PCNL) is a preferred treatment method. Infection-related complications after percutaneous nephrolithotomy include transient fever, systemic inflammatory response syndrome, and urinary sepsis, especially urinary sepsis, which are considered to be common causes of death after percutaneous nephrolithotomy. Therefore, early identification and timely intervention of biomarkers can reduce the incidence and mortality of postoperative sepsis, as well as the length of hospital stay and hospitalization costs. This article reviews the biomarkers for early identification of urinary tract infection after PCNL, such as traditional inflammatory indicators, new inflammatory indicators, and composite inflammatory indicators.
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Co-occurrence of acute ischemic stroke and acute myocardial infarction,named concomitant cerebrocardiac infarction,is a rare yet critical medical challenge.Optimal management strategies remain undefined,particularly for ST-segment elevation myocardial infarction.This editorial discusses a case report by Zheng and Liu,where a 27-year-old male with simultaneous acute transmural anterior myocardial infarction and acute ischemic stroke was treated with urgent thrombolysis followed by elective percutaneous coronary intervention.We offer a perspective on the rationale behind this combined approach,discussing the delicate balance of addressing acute stroke and myocardial infarction.This commentary highlights the critical need for further research and clinical discussion to develop evidence-based strategies for optimal patient care in these complex,time-sensitive cases,encouraging critical evaluation of current practices.

文摘BACKGROUND Comminuted calcaneal fractures present significant treatment challenges.Open reduction and internal fixation carries risks such as infection and skin necrosis,while minimally invasive techniques may compromise reduction stability.Conservative management is generally limited to minimally displaced fractures.Traditional Chinese manual bone-setting has a long history in fracture treatment and is renowned globally for achieving functional reduction.It offers distinct advantages including lower cost,minimal soft tissue trauma,and the avoidance of expensive reduction equipment or internal fixation materials.CASE SUMMARY A 60-year-old female presented with left foot pain and limited mobility following a fall.Computed tomography scan revealed a Sanders type IV calcaneal fracture with a Böhler angle of 0°.A standardized,stepwise Traditional Chinese manual bone-setting was initially performed,followed by percutaneous screw fixation through several mini-incisions after satisfactory alignment was confirmed under fluoroscopy.The Visual Analog Scale score decreased from 5 on postoperative day 1 to 3 by day 3.The American Orthopaedic Foot and Ankle Society score improved from 73 at 6 weeks to 90 at 3 months,indicating rapid functional recovery and high patient satisfaction.At 7 months postoperatively,the American Orthopaedic Foot and Ankle Society score reached 95,prompting removal of internal fixation.At the 6-year follow-up,reduction remained well maintained,with the Böhler angle preserved at 22°.CONCLUSION The combination of Traditional Chinese manual bone-setting and percutaneous screw fixation achieved satisfactory functional reduction for comminuted calcaneal fractures.
文摘BACKGROUND Primary percutaneous coronary intervention(PCI)is the preferred treatment for ST-segment elevation myocardial infarction(STEMI).However,in patients with high thrombus burden,immediate stenting during PCI can lead to poor outcomes due to the risk of thrombus migration and subsequent microvascular occlusion,resulting in no-reflow phenomena.Deferred stenting offers a potential advantage by allowing for the reduction of thrombus load,which may help to minimize the incidence of slow-flow and no-reflow complications.This study explores the effectiveness of a deferred stenting strategy in improving outcomes for STEMI patients.AIM To evaluate the effectiveness and safety of deferred PCI in a real-world setting in acute STEMI patients.METHODS RESULTS Anterior wall myocardial infarction was the predominant type of STEMI in 62%of the selected 55 patients(mean age:54 years;70%males),and diabetes mellitus was the most common risk factor(18.2%),followed by hypertension(16.2%).On the second angiogram of these patients measures of thrombus grade,thrombolysis in myocardial infarction flow grade,myocardial blush grade,and severity of stenosis of culprit lesion were consid-erably improved compared to the first angiogram,and the average culprit artery diameter had increased by 7.8%.Most patients(60%)had an uneventful hospital stay during the second angiogram and an uneventful intrapro-cedural course(85.19%),with slow-flow/no-reflow occurring only in 7.4%of the patients;these patients recovered after taking vasodilator drugs.In 29.3%of patients,the culprit artery was recanalized,preventing unnecessary stent deployment.CONCLUSION Deferred PCI strategy is safe and reduces the thrombus burden,improves thrombolysis in myocardial infarction(TIMI)flow,improves myocardial blush grade,and prevents unwarranted stent deployment.
文摘BACKGROUND Glycated hemoglobin(HbA1c)is a well-established biomarker for diagnosing and managing diabetes.However,its prognostic significance in patients without diagnosed diabetes undergoing percutaneous coronary intervention(PCI)remains uncertain.This systematic review and meta-analysis evaluates the association between elevated HbA1c levels in the prediabetic range(≥5.7%)and adverse cardiovascular outcomes in this population.AIM To investigate the association between elevated HbA1c levels in the prediabetic range and adverse outcomes in patients without diagnosed diabetes undergoing PCI.METHODS We systematically searched PubMed,EMBASE,and Cochrane Central through April 2025 for studies comparing clinical outcomes in coronary artery disease(CAD)patients without a prior diabetes diagnosis,stratified by HbA1c levels(≥5.7% vs<5.7%).Risk ratios(RR)with 95%confidence intervals(CI)were pooled using a random-effects model.Statistical analysis was performed using R software(version 4.3.2).Primary outcomes were long-term allcause mortality and major adverse cardiovascular events(MACE);secondary outcomes included short-term mortality and cardiac death.RESULTS Ten studies involving 32403 patients(mean age:60 years;29% female)were included.Elevated HbA1c levels in patients without diagnosed diabetes were significantly associated with increased risk of long-term all-cause mortality(RR:1.30;95% CI:1.10-1.54;P<0.01;I2=41%)and MACEs(RR:1.31;95% CI:1.01-1.69;P=0.04;I2=61%).Although the risks of short-term all-cause mortality(RR:1.16;95% CI:0.88-1.53;P=0.29;I2=1%)and cardiac mortality(RR:1.76;95% CI:0.85-3.67;P=0.13;I2=94%)were elevated,they did not reach statistical significance.Sensitivity analyses confirmed the robustness of the findings despite moderate to high heterogeneity in some outcomes.CONCLUSION Among CAD patients without diagnosed diabetes,elevated HbA1c levels in the prediabetic range(≥5.7%)are independently associated with worse long-term outcomes following PCI.HbA1c may serve as a valuable biomarker for post-PCI risk stratification in this metabolically at-risk group.
