Fragile hearts:Unveiling the crucial layers of frailty in elderly patients undergoing percutaneous coronary interventions

Wang and Liu's systematic review of frailty among elderly patients undergoing percutaneous coronary intervention(PCI)revealed that patients with frailty have significantly higher risks of all-cause and in-hospital death,major undesirable cardiovascular events,and major haemorrhage.Frailty is associated with adverse events,prolonged hospital stays,increased complications,and elevated mortality risk due to diminished physiological reserves.Integrating frailty into risk assessment tools is crucial,and gait speed has emerged as a key predictor of frailty.Recognizing the impact of frailty leads to personalized and informed decisionmaking,and frailty assessments should be performed.This holistic approach can inform tailored interventions,thereby optimizing outcomes for this vulnerable population undergoing PCI.

Predictors of Complications after Sheath Removal Post Transfemoral Percutaneous Coronary Interventions

Background: Complications post percutaneous coronary interventions (PCI) are more threatening than it was previously thought so that necessary measures should be taken to minimize those risks. Objective: To identify the risk factors related to patient and procedure which could be used as predictors of complications after sheath removal post PCI. Methods: The study used a prospective non-experimental correlational descriptive. Design: The sample was chosen conveniently from three different hospitals and included 118 patients who were subjected to PCI. Results: Three models were used to predict complications. In the first model, none of the baseline variables were predictive of complications. In the second model, the only type of procedure (diagnostic, stent or balloon) was predictive of complications. In the third model, compression time was found to be a risk factor and a predictor of complications after sheath removal. Conclusion: Nurses and medical professionals are in a vital position to prevent, detect and manage PCI complications at the earliest possible opportunity. It is a must to assess and categorize patients in accordance with their risk level to develop post PCI and post sheath removal complications, in order to plan management strategies to decrease the health costs and the suffering.

Outcomes after percutaneous coronary interventions in patients with chronic kidney disease

Introduction Chronic kidney disease (CKD) is a significant contributor to cardiovascular morbidity and mortality.Patients with CKD are known to have a greater prevalence of cardiovascular disease than the general population,1 and patients with concurrent CKD and coronary artery disease (CAD) have greater mortality than patients without CKD.2-4 The rate of cardiovascular mortality is approximately 50%,five to 10 times higher than the general population.

Stent visualization methods to guide percutaneous coronary interventions and assess long-term patency

Evaluation of acute percutaneous coronary intervention(PCI)results and longterm follow-up remains challenging with ongoing stent designs.Several imaging tools have been developed to assess native vessel atherosclerosis and stent expansion,improving overall PCI results and reducing adverse cardiac events.Quantitative coronary analysis has played a crucial role in quantifying the extent of coronary artery disease and stent results.Digital stent enhancement methods have been well validated and improved stent strut visualization.Intravascular imaging remains the gold standard in PCI guidance but adds costs and time to the procedure.With a recent shift towards non-invasive imaging assessment and coronary computed tomography angiography imaging have shown promising results.We hereby review novel stent visualization techniques used to guide PCI and assess stent patency in the modern PCI era.

Safety and efficacy of dual antiplatelet therapy after percutaneous coronary interventions in patients with end-stage liver disease

The prevalence of coronary artery disease(CAD)increases in patients with endstage liver disease,with part of them receiving the percutaneous coronary intervention(PCI)as a treatment option.Dual antiplatelet therapy(DAPT),a standard of care after PCI,could result in catastrophic consequences in this population.Before PCI and the start of DAPT,it is recommended to assess patient bleeding risk.Based on novel findings,liver cirrhosis does not necessarily lead to a significant increase in bleeding complications.Furthermore,conventional methods,such as the international normalized ratio,might not be appropriate in assessing individual bleeding risk.The highest bleeding risk among cirrhotic patients has a subgroup with severe thrombocytopenia(<50×10^(9)/L)and elevated portal pressure.Therefore,every effort should be made to maintain thrombocyte count above>50×10^(9)/L and prevent variceal bleeding.There is no solid evidence for DAPT in patients with cirrhosis.However,randomized trials investigating short(one month)DAPT duration after PCI with new drug-eluting stents(DES)in a high bleeding risk patient population can be implemented in patients with cirrhosis.Based on retrospective studies(with older stents and protocols),PCI and DAPT appear to be safe but with a higher risk of bleeding complications with longer DAPT usage.Finally,novel methods in assessing CAD severity should be performed to avoid unnecessary PCI and potential risks associated with DAPT.When indicated,PCI should be performed over radial artery using contemporary DES.Complementary medical therapy,such as proton pump inhibitors and beta-blockers,should be prescribed for lower bleeding risk patients.Novel approaches,such as thromboelastography and“preventive”upper endoscopies in PCI circumstances,warn clinical confirmation.

Long-term outcomes of high-risk percutaneous coronary interventions under extracorporeal membrane oxygenation support:An observational study

BACKGROUND Venoarterial extracorporeal membrane oxygenation(VA-ECMO)offers hemodynamic support for patients undergoing high-risk percutaneous coronary interventions(PCIs).However,long-term outcomes associated with VA-ECMO have not previously been studied.AIM To explore long-term outcomes in high-risk cases undergoing PCI supported by VA-ECMO.METHODS In the present observational cohort study,61 patients who received VA-ECMOsupported high-risk PCI between April 2012 and January 2020 at the Sixth Medical Center of Chinese People’s Liberation Army General Hospital were enrolled.The endpoint characteristics such as all-cause mortality,repeated cardiovascular diseases,and cardiac death were examined.RESULTS Among 61 patients,three failed stent implantation due to chronic total occlusions with severely calcified lesions.One patient showed VA-ECMO intolerance because of high left ventricular afterload.PCI was successfully performed in 57 patients(93.4%).The in-hospital mortality was 23.0%,and the overall survival was 45.9%,with a median follow-up period of 38.6(8.6-62.1)mo.CONCLUSION VA-ECMO can be used as a support in patients undergoing high-risk PCI as it is associated with favorable long-term patient survival.

Advances in Periprocedural Anticoagulation for Percutaneous Coronary Interventions

Percutaneous coronary intervention (PCI) is commonly used in the surgical treatment of patients with various types of cardiac diseases. Some patients require long-term anticoagulation in the presence of deep vein thrombosis, atrial fibrillation and mechanical heart valves, and inappropriate anticoagulation during the perioperative period may lead to bleeding events or thrombotic events. In this paper, the importance of anticoagulation in the practical application of percutaneous coronary intervention (PCI) is first introduced, and then the various drug regimens used in the perioperative anticoagulation of percutaneous coronary intervention are explored in detail in the light of current research advances, with a view to providing guidance for clinical practice.

Unloading and successful treatment with bioresorbable stents during percutaneous coronary intervention:A case report

BACKGROUND With the development of percutaneous coronary intervention(PCI),the number of interventional procedures without implantation,such as bioresorbable stents(BRS)and drug-coated balloons,has increased annually.Metal drug-eluting stent unloading is one of the most common clinical complications.Comparatively,BRS detachment is more concealed and harmful,but has yet to be reported in clinical research.In this study,we report a case of BRS unloading and successful rescue.This is a case of a 59-year-old male with the following medical history:“Type 2 diabetes mellitus”for 2 years,maintained with metformin extended-release tablets,1 g PO BID;“hypertension”for 20 years,with long-term use of metoprolol sustained-release tablets,47.5 mg PO QD;“hyperlipidemia”for 20 years,without regular medication.He was admitted to the emergency department of our hospital due to intermittent chest pain lasting 18 hours,on February 20,2022 at 15:35.Electrocardiogram results showed sinus rhythm,ST-segment elevation in leads I and avL,and poor R-wave progression in leads V1–3.High-sensitivity troponin I level was 4.59 ng/mL,indicating an acute high lateral wall myocardial infarction.The patient’s family requested treatment with BRS,without implanta-tion.During PCI,the BRS became unloaded but was successfully rescued.The patient was followed up for 2 years;he had no episodes of angina pectoris and was in generally good condition.CONCLUSION We describe a case of a 59-year-old male experienced BRS unloading and successful rescue.By analyzing images,the causes of BRS unloading and the treatment plan are discussed to provide insights for BRS release operations.We discuss preventive measures for BRS unloading.

Impact of frailty on outcomes of elderly patients undergoing percutaneous coronary intervention: A systematic review and metaanalysis

BACKGROUND Frailty is a common condition in elderly patients who receive percutaneous coronary intervention(PCI).However,how frailty affects clinical outcomes in this group is unclear.AIM To assess the link between frailty and the outcomes,such as in-hospital complic-ations,post-procedural complications,and mortality,in elderly patients post-PCI.METHODS The PubMed/MEDLINE,EMBASE,Cochrane Library,and Web of Science databases were screened for publications up to August 2023.The primary outcomes assessed were in-hospital and all-cause mortality,major adverse cardiovascular events(MACEs),and major bleeding.The Newcastle-Ottawa Scale was used for quality assessment.RESULTS Twenty-one studies with 739693 elderly patients undergoing PCI were included.Frailty was consistently associated with adverse outcomes.Frail patients had significantly higher risks of in-hospital mortality[risk ratio:3.45,95%confidence interval(95%CI):1.90-6.25],all-cause mortality[hazard ratio(HR):2.08,95%CI:1.78-2.43],MACEs(HR:2.92,95%CI:1.85-4.60),and major bleeding(HR:4.60,95%CI:2.89-7.32)compared to non-frail patients.CONCLUSION Frailty is a pivotal determinant in the prediction of risk of mortality,development of MACEs,and major bleeding in elderly individuals undergoing percutaneous coronary intervention.

Impact of primary percutaneous coronary intervention on ST-segment elevation myocardial infarction patients:A comprehensive analysis

BACKGROUND Myocardial infarction,particularly ST-segment elevation myocardial infarction(STEMI),is a key global mortality cause.Our study investigated predictors of mortality in 96 STEMI patients undergoing primary percutaneous coronary intervention at Erbil Cardiac Center.Multiple factors were identified influencing in-hospital mortality.Significantly,time from symptom onset to hospital arrival emerged as a decisive factor.Consequently,our study hypothesis is:"Reducing time from symptom onset to hospital arrival significantly improves STEMI prognosis."AIM To determine the key factors influencing mortality rates in STEMI patients.METHODS We studied 96 consecutive STEMI patients undergoing primary percutaneous coronary intervention(PPCI)at the Erbil Cardiac Center.Their clinical histories were compiled,and coronary evaluations were performed via angiography on admission.Data included comorbid conditions,onset of cardiogenic shock,complications during PPCI,and more.Post-discharge,one-month follow-up assessments were completed.Statistical significance was set at P<0.05.RESULTS Our results unearthed several significant findings.The in-hospital and 30-d mortality rates among the 96 STEMI patients were 11.2%and 2.3%respectively.On the investigation of independent predictors of in-hospital mortality,we identified atypical presentation,onset of cardiogenic shock,presence of chronic kidney disease,Thrombolysis In Myocardial Infarction grades 0/1/2,triple vessel disease,ventricular tachycardia/ventricular fibrillation,coronary dissection,and the no-reflow phenomenon.Specifically,the recorded average time from symptom onset to hospital arrival amongst patients who did not survive was significantly longer(6.92±3.86 h)compared to those who survived(3.61±1.67 h),P<0.001.These findings underscore the critical role of timely intervention in improving the survival outcomes of STEMI patients.CONCLUSION Our results affirm that early hospital arrival after symptom onset significantly improves survival rates in STEMI patients,highlighting the critical need for prompt intervention.

Evaluation of CRUSADE and ACUITY-HORIZONS Scores for Predicting Long-term Out-of-Hospital Bleeding after Percutaneous Coronary Interventions

Background：There is scanty evidence concerning the ability of Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes with Early Implementation of the ACC/AHA Guidelines （CRUSADE） and Acute Catheterization and Urgent Intervention Triage Strategy and Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction （ACUITY-HORIZONS） scores to predict out-of-hospital bleeding risk after percutaneous coronary interventions （PCIs） with drug-eluting stents （DES） in patients receiving dual antiplatelet therapy.We aimed to assess and compare the long-term prognostic value of these scores regarding out-of-hospital bleeding risk in such patients.Methods：We performed a prospective observational study of 10,724 patients undergoing PCI between January and December 2013 in Fuwai Hospital,China.All patients were followed up for 2 years and evaluated through the Fuwai Hospital Follow-up Center.Major bleeding was defined as Types 2,3,and 5 according to Bleeding Academic Research Consortium Definition criteria.Results：During a 2-year follow-up,245 of 9782 patients （2.5%） had major bleeding （MB）.CRUSADE （21.00 [12.00,29.75] vs.18.00 [11.00,26.00],P 〈 0.001） and ACUITY-HORIZONS （9.00 [3.00,14.00] vs.6.00 [3.00,12.00],P 〈 0.001） risk scores were both significantly higher in the MB than non-MB groups.Both scores showed a moderate predictive value for MB in the whole study cohort （area under the receiver-operating characteristics curve [AUROC],0.565;95% confidence interval [CI],0.529-0.601,P =0.001;AUROC,0.566;95% CI,0.529-0.603,P 〈 0.001,respectively） and in the acute coronary syndrome （ACS） subgroup （AUROC：0.579,95% CI：0.531-）.627,P =0.001;AUROC,0.591;95% CI,0.544-0.638,P 〈 0.001,respectively）.However,neither score was a significant predictor in the non-ACS subgroup （P 〉 0.05）.The value of CRUSADE and ACUITY-HORIZONS scores did not differ significantly （P 〉 0.05） in the whole cohort,ACS subgroup,or non-ACS subgroup.Conclusions：CRUSADE and ACUITY-HORIZONS scores showed statistically significant but relatively limited long-term prognostic value for out-of-hospital MB after PCI with DES in a cohort of Chinese patients.The value of CRUSADE and ACUITY-HORIZONS scores did not differ significantly （P 〉 0.05） in the whole cohort,ACS subgroup,or non-ACS subgroup.

Characteristics and risk factors of cerebrovascular accidents after percutaneous coronary interventions in patients with history of stroke

Background Percutaneous coronary intervention （PCI） is a well-established method for managing coronary diseases. However, the increasing use of PCI has led to an increased incidence of acute cerebrovascular accidents （CVA） related to PCI. In this study, we investigated the characteristics and risk factors of CVA after PCI in patients with known stroke history. Methods Between January 1, 2005 and March 1, 2009, 621 patients with a history of stroke underwent a total of 665 PCI procedures and were included in this retrospective study. Demographic and clinical characteristics, previous medications, procedures, neurologic deficits, location of lesion and in-hospital clinical outcomes of patients who developed a CVA after the cardiac catheterization laboratory visit and before discharge were reviewed. Results Acute CVA was diagnosed in 53 （8.5%） patients during the operation or the perioperative period. Seventeen patients suffered from transient ischemic attack, thirty-four patients suffered from cerebral infarction and two patients suffered from cerebral hemorrhage. The risk factors for CVA after PCI in stroke patients were： admission with an acute coronary syndrome, use of an intra-aortic balloon pump, urgent or emergency procedures, diabetes mellitus, and poor left ventricular systolic function, arterial fibrillation, previous myocardial infarction, dyslipidemia, tobacco use, and no/irregular use of anti-platelet medications. Conclusions The incidence of CVA during and after PCI in patients with history of stroke is much higher than that in patients without history of stroke. Patients with atrial fibrillation, previous myocardial infarction, diabetes mellitus, dyslipidemia, tobacco use, and no or irregular use of anti-platelet medications were at higher risk for recurrent stroke. This study showed a strong association between acute coronary svndromes and in-hospital stroke after PCI.

Bioresorbable stent unloading during percutaneous coronary intervention:Early detection and management

In this letter,we comment on a recent case report by Sun et al in the World Journal of Cardiology.The report describes the successful management of a rare complication:The unloading or detachment of a bioresorbable stent(BRS)during percutaneous coronary intervention(PCI)in a male patient.The unloading of BRS was detected via angiography and intravascular ultrasound(IVUS)imaging of the left coronary artery and left anterior descending artery.Although this case is interesting,the authors’report lacked crucial details.Specifically,insufficient information about the type of BRS used,potential causes of BRS unloading,or whether optical coherence tomography(OCT)imaging for coronary arteries was performed before,during,or after PCI.The OCT imaging of coronary arteries before PCI can potentially prevent BRS unloading due to its higher resolution compared to IVUS.In addition,despite detecting myocardial bridging during the PCI,the authors did not provide any details regarding this variation.Here we discuss the various types of BRS,the importance of OCT in PCI,and the clinical relevance of myocardial bridging.

Comprehensive analysis of the impact of primary percutaneous coronary intervention on patients with ST-segment elevation myocardial infarction

This comprehensive analysis by Saeed and Faeq investigates the impact of primary percutaneous coronary intervention(pPCI)on mortality among patients with ST-segment elevation myocardial infarction(STEMI)at the Erbil Cardiac Center.Analyzing data from 96 consecutive STEMI patients,the study identified significant predictors of in-hospital mortality,emphasizing the critical impact of time of hospital arrival post-symptom onset on overall prognosis.Findings indicate that factors such as atypical presentation,cardiogenic shock,chronic kidney disease,and specific coronary complications are associated with higher mortality rates.The study underscores the necessity of prompt medical intervention for improving survival outcomes in STEMI patients,especially in the high-risk subgroup.This research offers valuable insights into optimizing STEMI management and enhancing patient survival rates through effective and timely pPCI.

Research Progress on the Depression Status and Nursing Intervention in Patients after Percutaneous Coronary Intervention

Percutaneous coronary intervention(PCI)is an effective treatment method for myocardial ischemic necrosis.Postoperative depression caused by PCI stress will adversely affect the prognosis of patients.This article reviews the current status and influencing factors of postoperative depression after PCI and summarizes the corresponding nursing interventions,to provide a literature reference to implement effective nursing interventions for depressed patients after clinical PCI.

Fundamentals of percutaneous coronary bifurcation interventions

Coronary bifurcation lesions(CBLs)account for 15%-20%of all percutaneous coronary interventions.The complex nature of these lesions is responsible for poorer procedural,early and late outcomes.This complex lesion subset has received great attention in the interventional cardiac community,and multiple stenting techniques have been developed.Of these,the provisional stenting technique is most often the default strategy;however,the elective double stenting(EDS)technique is preferred in certain subsets of complex CBLs.The double kissing crush technique may be the preferred EDS technique because of its efficacy and safety in comparative trials;however,this technique consists of many steps and requires training.Many new methods have recently been added to the EDS techniques to provide better stent scaffolding and to reduce early and late adverse outcomes.Intravascular imaging is necessary to determine the interventional strategy and postinterventional results.This review discusses the basic concepts,contemporary percutaneous interventional technical approaches,new methods,and controversial treatment issues of CBLs.

Contrast use in relation to the arterial access site for percutaneous coronary intervention:A comprehensive meta-analysis of randomized trials

AIM To compare the amount of contrast used during percutaneous coronary intervention(PCI) via trans-radial access(TRA) vs trans-femoral access(TFA).METHODS Scientific databases and websites were searched for:randomizedcontrolledtrials(RCTs). Data were extracted by two independent reviewers and was summarized as the weighted mean difference(WMD) of contrast used with a 95%CI using a random-effects model. RESULTS The meta-analysis included 13 RCTs with a total of 3165 patients. There was no difference between the two strategies in the amount of contrast used(WMD =-0.65 mL,95%CI:-10.94-9.46 mL; P = 0.901). CONCLUSION This meta-analysis shows that in patients undergoing PCI,the amount of contrast volume used was not different between TRA and TFA.

A comparative study on transradial vs transfemoral artery access for primary percutaneous coronary intervention in patients with acute myocardial infarction

Objective Comparative study on the feasibility,safety and outcome of transradial artery and transfemoral artery access for primary percutaneous coronary intervention (PCI) in patients with acute myocardial infarction(AMI).Methods Two hundred and eight patients with AMI episoded within 12 hours, male 159, female 49, age 58.9 ±11.9 (34～88)years, were randomly divided into transradial artery access for primary PCI (TRA pPCI) group of 106 cases and transfemoral artery access for PCI (TFA pPCI) group of 102 cases during Sept, 2000 to Aug, 2002. The protocols of the manipulation duration and the effect for TRA pPCI and TFA pPCI procedures were respectively compared, including the time of transradial artery puncture and the rate of puncture success at first time ; the time of guiding catheter engaging into target coronary ostium; the rate of patence in infarct related artery (IRA); total duration of manipulation and the successful rate.The incidence of complications such as bleeding, vessel injury,thrombi and embolism as well as the average stay of hospitalization between two groups was compared. The status and the incidance of vessel spasm were observed and the effect of medicine administration to prevent from and relieve the vascular spasm was evaluated. The time of Allen’s test before and after TRA pPCI , the inner diameter and the peak of blood velocity of the right and left radial artery were investigated with color Doppler vessel echography as well as the complications of radial artery were followed up 1 month after TRA pPCI procedure. Results Two cases in every TRA pPCI and TFA pPCI groups were crossed over each other because procedure of the transradial or transfemoral access was failure. One handred and six vessels (48 vessels in LAD,22 vessels in LCX and 36 vessels in RCA) associated with 28 vessels of total occlusion in TRA pPCI group and 102 vessels (51 vessels in LAD,18 veesles in LCX and 33 vessels in RCA) with 24 vessels in total occlusion in TFA pPCI group were angioplasticized . The successful rates of the first time puncture in access artery, the re patence IRA and pPCI were similar in TRA pPCI and TFA pPCI groups ( 93.4% vs 96.1% ;100% vs 100%; 96.2% vs 97.1% , P >0.05 ). There were no significant diffierence in the average time of puncture time of access artery ,engaging in target vessels of guiding catheters and the total procedure of PCI between the two groups ( 1.3 ±0.3s vs 1.2 ±0.3s ; 6.0 ±1.6min vs 5.8 ±0.9min ; 49.2 ±24.1min vs 46.5 ± 26.4min , P >0.05 ). The access artery complications such as bleeding ,hematoma and embolism as well the veneous thrombosis in TFA pPCI group were much more than those in TRA pPCI group(p< 0.01 ). Although slight artery spasm of 4.7% cases in TRA pPCI group was happened during the procedure of PCI , the procedure had being continued after administration of medicine to release the spasm. The time of Allen’s test ,diameter and the systolic velocity of blood in daul radial arteries were no significant change before and after pPCI.Conclusions The duration and effect by TRA pPCI for AMI with stable hemodynamics was similar to TFA pPCI. The complications such as of bleeding,vessel injury, thrombi and embolism by TRA pPCI were few, and it was unnecessary to discontinue the anticoagulation medicine. TRA pPCI might be selected as a access vessel for pPCI in AMI patients with stable hemodynamics.

A randomized trail comparing primary percutaneous coronary intervention with a strategy of short-acting thrombolysis and immediate planned primary percutaneous coronary intervention in acute myocardial infarction

Objective This study was to evaluate the efficacy and safety of a short acting reduced dose fibrinolytic regimen to promote early infarct related artery (IRA) patency for acyute myocardial infarction (AMI) patients referred for percutaneous coronary intervention (PCI).Methods Following aspirin and heparin, 166 patients were randomized to a 50 mg bolus of recombinant tissue type plasminogen activator(rt PA) or to a same volume sodium chloride injection followed by immediate primary PCI. The end points included patency rates on catheterization laboratory (cath lab) arrival, revascularization results when PCI was performed, complication rates, left ventricular function and restored patency rate following PCI. Results Patency on cath lab arrival was 64% with rt PA (34% TIMI 3,30% TIMI 2), while 31% of placebo (13% TIMI 3, 18% TIMI 2). There was no difference in the restored TIMI 3 rates of IRA between the two groups (85% vs 87%). No difference were observed in stroke or major bleeding. Left ventricular function was similar in both groups (52±9% vs 50±8%), but left ventricular ejection fraction fraction (LVEF) was higher with patent IRA (TIMI 3) on cath lab arrival than that of others (56±12% vs 48±10%).Conclusions Strategy thrombolytic regimens were compatible with subsequent PCI lead to more frequenc early recanalization (before cath lab arrival), which facilitates greater left ventricular function preservation with no augmentation of adverse events.

Physical activity levels and predictors in patients following percutaneous coronary intervention: a cross-sectional study

Objective: To examine physical activity(PA) of post-percutaneous coronary intervention(PCI) patients and explore the demographic, clinical, and social psychological characteristics associated with PA levels. Methods: A total of 246 post-PCI patients from the Peking University Third Hospital in Beijing, China, were included in this crosssectional study through convenience sampling. Data were collected from a self-repor ted questionnaire. PA was categorized into low, moderate, or high levels. The ordinal multinomial logistic regression model was used to estimate the relationship among demographic, medical, and psychosocial characteristics. Results: The overall prevalence of low, moderate, and high PA was 20%, 70%, and 10%, respectively. For the domain-specific PA patterns, most par ticipants took par t in leisure-time PA(84.5%);walking was the most common PA. Increased motivation and selfefficacy, lower monthly income, and unemployment were predictors of high PA. Conclusions: PA levels in post-PCI patients was not optimal, and leisure-time PA had the highest par ticipation rate. Analyses of influencing factors can provide medical staff and health workers information to focus on high-risk groups and introduce more tailored interventions. Future studies can explore more regions, and ecological models can be introduced to study more influencing factors.
