Impact of sex difference on clinical outcomes in acute myocardial infarction patients with single-vessel and multi-vessel disease: based on Korea Acute Myocardial Infarction Registry-National Institute of Health.

ABSTRACT:

Background

Several studies have compared clinical outcomes according to sex in patients with acute myocardial infarction (AMI). However, studies evaluating sex differences in clinical outcomes of single-vessel disease (SVD) and multi-vessel disease (MVD) in Korean patients with AMI are lacking. Therefore, this study aimed to analyze sex differences in the clinical characteristics of patients with AMI with SVD and MVD and to evaluate the impact of sex differences on the clinical outcomes in patients with AMI with SVD and MVD.

Methods

A total of 11,002 AMI patients from November 2011 to June 2015 in the Korea AMI Registry, National Institute of Health, were enrolled. The current study was retrospective observational study. Patients were divided into SVD (n=5,644) and MVD (n=5,358) groups, and clinical impact of sex difference were analyzed by propensity score matching analysis and Cox proportional hazard regression model.

Results

Women were older and had poor baseline clinical characteristics than men. Propensity score-matched analysis of men and women with SVD and MVD revealed that the adjusted 3-year risk of major adverse cardiac event (MACE) (15.0% vs. 9.4%; hazard ratio, 1.86; 95% confidence interval, 1.10-3.13; P=0.020) was higher in women with SVD aged <65 years. However, the incidence and risk of MACE were similar for men and women with MVD, and those with SVD aged ≥65 years.

Conclusions

In the present study of Korean patients with AMI, women were older and exhibited a higher prevalence of comorbidities than men. Women with SVD aged <65 years had a significantly higher risk of MACE.

Project description:BackgroundThis study assessed sex differences in treatments, all-cause mortality, relative survival, and excess mortality following acute myocardial infarction.Methods and resultsA population-based cohort of all hospitals providing acute myocardial infarction care in Sweden (SWEDEHEART [Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies]) from 2003 to 2013 was included in the analysis. Excess mortality rate ratios (EMRRs), adjusted for clinical characteristics and guideline-indicated treatments after matching by age, sex, and year to background mortality data, were estimated. Although there were no sex differences in all-cause mortality adjusted for age, year of hospitalization, and comorbidities for ST-segment-elevation myocardial infarction (STEMI) and non-STEMI at 1 year (mortality rate ratio: 1.01 [95% confidence interval (CI), 0.96-1.05] and 0.97 [95% CI, 0.95-0.99], respectively) and 5 years (mortality rate ratio: 1.03 [95% CI, 0.99-1.07] and 0.97 [95% CI, 0.95-0.99], respectively), excess mortality was higher among women compared with men for STEMI and non-STEMI at 1 year (EMRR: 1.89 [95% CI, 1.66-2.16] and 1.20 [95% CI, 1.16-1.24], respectively) and 5 years (EMRR: 1.60 [95% CI, 1.48-1.72] and 1.26 [95% CI, 1.21-1.32], respectively). After further adjustment for the use of guideline-indicated treatments, excess mortality among women with non-STEMI was not significant at 1 year (EMRR: 1.01 [95% CI, 0.97-1.04]) and slightly higher at 5 years (EMRR: 1.07 [95% CI, 1.02-1.12]). For STEMI, adjustment for treatments attenuated the excess mortality for women at 1 year (EMRR: 1.43 [95% CI, 1.26-1.62]) and 5 years (EMRR: 1.31 [95% CI, 1.19-1.43]).ConclusionsWomen with acute myocardial infarction did not have statistically different all-cause mortality, but had higher excess mortality compared with men that was attenuated after adjustment for the use of guideline-indicated treatments. This suggests that improved adherence to guideline recommendations for the treatment of acute myocardial infarction may reduce premature cardiovascular death among women.Clinical trial registrationURL: https://www.clinicaltrials.gov.
