Predictors of recurrent acute myocardial infarction despite successful percutaneous coronary intervention.

ABSTRACT:

Background/aims

Recurrent acute myocardial infarction (AMI) is an adverse cardiac event in patients with a first AMI. The predictors of recurrent AMI after the first AMI in patients who underwent successful percutaneous coronary intervention (PCI) have not been elucidated.

Methods

We analyzed the data collected from 9,869 patients (63.2 ± 12.4 years, men:women = 7,446:2,423) who were enrolled in the Korea Acute Myocardial Infarction Registry-National Institute of Health between November 2011 and October 2015, had suffered their first AMI and had received successful PCI during the index hospitalization. Multivariable logistic regression analysis was performed to identify the independent predictors of recurrent AMI following the first AMI.

Results

The cumulative incidence of recurrent AMI after successful PCI was 3.6% (359/9,869). According to the multivariable logistic regression analysis, the significant predictive factors for recurrent AMI were diabetes mellitus, renal dysfunction, atypical chest pain, and multivessel disease.

Conclusion

In this Korean prospective cohort study, the independent predictors of recurrent AMI after successful PCI for the first AMI were diabetes mellitus, renal dysfunction, atypical chest pain, and multivessel disease.

Project description:BackgroundWomen have been underrepresented in the literature; the effects of female sex on outcomes in patients with acute myocardial infarction (AMI) remain unclear.ObjectivesThis study compares the real-world outcomes of women and men with AMI who have undergone revascularization via percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery (CABG).MethodsThis is a retrospective cohort study utilizing data from the Taiwan National Health Insurance database. We identified patients who were admitted for AMI and who underwent coronary revascularization during the index admission period between January 1, 2001, and December 31, 2013. Patients were then categorized based on the treatment received into PCI and CABG groups. In-hospital and long-term outcomes were compared between women and men in each group. Interaction tests were then performed to determine whether the differences between sexes were modified by the mode of revascularization. Analyses were repeated after propensity score matching between women and men in each group to minimize possible confounders. We also conducted subgroup analyses, stratifying by the presence of diabetes mellitus, congestive heart failure, and chronic kidney disease.ResultsWe enrolled 67,534 patients who met the inclusion criteria in the analysis; 60,207 patients had undergone PCI (13,514 female and 46,693 male), while 7327 patients had received CABG (1762 female and 5565 male). Prior to matching, enrolled female patients were older on average, with more comorbidities. In-hospital and long-term outcomes were worse in women, particularly in the PCI group. After matching, the incidence of hospitalization for heart failure (HHF) was higher in women (10.4% vs 8.0%, OR 1.32, 95% CI 1.22-1.43), with fewer repeat revascularizations (28.1% vs 32.4%, OR 0.84, 95% CI 0.81-0.88). Both observations were more pronounced in the PCI group (HHF: P for interaction = 0.0496; repeat revascularization: P for interaction = 0.021).ConclusionsWomen presenting with AMI exhibited worse in-hospital and long-term outcomes than men, especially among women who received PCI as the initial mode of revascularization. Women who underwent PCI were more likely to be admitted for heart failure during follow-up. Possible socioeconomic inequalities or a distinct pathobiology of cardiac ischemia between sexes may underlie these results; thus, further investigation is needed.

Project description:BackgroundPrimary percutaneous coronary intervention (PPCI) has been widely recognized as the preferred treatment for ST-segment-elevation myocardial infarction (STEMI). However, substantial numbers of STEMI patients cannot receive timely PPCI. Early fibrinolysis followed by routine percutaneous coronary intervention (FPCI) has been proposed as an effective and safe alternative for eligible patients. To date, few studies have compared FPCI with PPCI in terms of microvascular reperfusion. This study aimed to evaluate the microvascular function of FPCI and PPCI.MethodsSTEMI patients at the Peking University First Hospital and Miyun Hospital were enrolled in this retrospective study between January 2015 to December 2020. Microvascular function documented by the coronary angiography-derived index of microvascular resistance (caIMR) was measured at the final angiogram after revascularization. The primary end point was the caIMR of the culprit vessels. The secondary end points were in-hospital and follow-up major adverse cardiovascular events (MACE), including cardiovascular death, non-fatal recurrent myocardial infarction, target-vessel revascularization (TVR), and non-fatal stroke/transient ischemic attacks (TIA). Details of the adverse clinical events were obtained from telephone interviews and electronic medical record systems until January 2022.ResultsIn total, 496 STEMI patients were enrolled in this cross-sectional retrospective study. Of these patients, 81 underwent FPCI, and 415 underwent PPCI. At the baseline, the PPCI patients had a higher-risk profile than the FPCI patients. The time from symptom onset to reperfusion therapy was significantly shorter in the FPCI group than the PPCI group (median 3.0 vs. 4.5 hours; P<0.001). The caIMR was significantly lower in the FPCI group than the PPCI group (median 20.34 vs. 40.33; P<0.001). The median follow-up duration was 4.1 years. During the follow-up period, the rate of MACE was lower in the FPCI group than the PPCI group [7 (10.1%) vs. 82 (20.8%), P=0.048]. After propensity score matching to adjust for the imbalances at the baseline, the caIMR remained significant and the clinical outcomes did not differ significantly between the two groups.ConclusionsIn eligible STEMI patients, clinically successful FPCI may be associated with better microvascular reperfusion and comparable clinical outcomes as compared with PPCI.

Project description:ImportanceDespite a rapid increase in percutaneous coronary intervention (PCI) procedures in China, little is known about patient-reported health status before and after PCI in patients without acute myocardial infarction (AMI).ObjectiveTo describe self-perceived angina-specific health status prior to PCI and 1 year after the procedure in patients without AMI in China.Design, setting, and participantsThe China Patient-Centered Evaluative Assessment of Cardiac Events (PEACE) Prospective Study of PCI was a population-based, multicenter cohort study of a consecutive sample of 1611 patients without AMI undergoing elective PCI. Participants were enrolled from 40 hospitals in 18 provinces in China from December 2012 to August 2014. Participants were eligible if they underwent PCI for stable and unstable angina and did not have AMI. Participants were excluded if they died in hospital, withdrew from follow-up, or had missing data on self-reported health status at baseline or at 1 year after PCI. The date of the analysis was September 15, 2018.ExposuresPercutaneous coronary intervention for ischemic heart disease.Main outcomes and measuresAngina frequency and angina-related quality of life were assessed with the Seattle Angina Questionnaire (SAQ) immediately prior to PCI and 1 year after the procedure. Either (1) an increase in the SAQ Angina Frequency score of 10 or more points or (2) an increase in the SAQ Quality-of-Life score of 10 or more points was considered to represent clinically significant improvement.ResultsOf 1611 patients, 520 (32.3%) were women; mean (SD) age was 61.3 (9.8) years. Among these patients, 443 (27.5%) had stable coronary artery disease and 1168 (72.5%) had unstable angina. One hundred fourteen of 443 patients undergoing PCI for stable coronary artery disease (25.7%) and 175 of 1168 undergoing PCI for unstable angina (15.0%) had no reported angina symptoms at the time of the procedure (SAQ Angina Frequency score = 100). Moreover, 18% of all patients (290) had minimal angina symptoms (SAQ Angina Frequency score >90) and, thus, no potential for substantial clinical improvement. Patients with smaller clinical improvements in angina symptom burden at 1 year following PCI had significantly higher baseline SAQ scores for all scales than patients with greater clinical improvement, but generally similar sociodemographic and procedural characteristics.Conclusions and relevanceIn this study, 25.7% of patients undergoing PCI for stable coronary artery disease had no reported angina symptoms at the time of the procedure. Patients with smaller clinical improvements in angina symptom burden had higher baseline SAQ scores, which highlights the importance of ascertaining impairment from angina among patients without AMI prior to performing PCI.
