RESUMO

BACKGROUND: Older women presenting with ST-segment elevation myocardial infarction (STEMI) are less likely to receive revascularization and have worse outcomes relative to their male counterparts. OBJECTIVES: This study sought to determine temporal trends and sex differences in revascularization and in-hospital outcomes of younger patients with STEMI. METHODS: We used the 2004 to 2011 Nationwide Inpatient Sample databases to identify all patients age 18 to 59 years hospitalized with STEMI. Temporal trends and sex differences in revascularization strategies, in-hospital mortality, and length of stay were analyzed. RESULTS: From 2004 to 2011, of 1,363,492 younger adults (age <60 years) with acute myocardial infarction, 632,930 (46.4%) had STEMI. Younger women with acute myocardial infarction were less likely than men to present with STEMI (adjusted odds ratio [OR]: 0.74; 95% confidence interval [CI]: 0.73 to 0.75). Younger women with STEMI were less likely to receive reperfusion as compared with younger men (percutaneous coronary intervention adjusted OR: 0.74; 95% CI: 0.73 to 0.75) (coronary artery bypass grafting adjusted OR: 0.61; 95% CI: 0.60 to 0.62) (thrombolysis adjusted OR: 0.80; 95% CI: 0.78 to 0.82). From 2004 to 2011, use of percutaneous coronary intervention for STEMI increased in both younger men (63.9% to 84.8%; ptrend < 0.001) and women (53.6% to 77.7%; ptrend < 0.001). In-hospital mortality was significantly higher in younger women compared with men (4.5% vs. 3.0%; adjusted OR: 1.11; 95% CI: 1.07 to 1.15). There was an increasing trend in risk-adjusted in-hospital mortality in both younger men and women during the study period. Length of stay decreased in both younger men and women (ptrend < 0.001). CONCLUSIONS: Younger women are less likely to receive revascularization for STEMI and have higher in-hospital mortality as compared with younger men. Use of percutaneous coronary intervention for STEMI and in-hospital mortality have increased, whereas length of stay has decreased in both sexes over the past several years.

RESUMO

BACKGROUND: There has been a paradigm shift in the definition of timing of early invasive strategy (EIS) for patients admitted with non-ST-elevation myocardial infarction (NSTEMI) in the last decade. Data on trends of EIS for NSTEMI and associated in-hospital outcomes are limited. Our aim is to analyze temporal trends in the incidence, utilization of early invasive strategy, and in-hospital outcomes of NSTEMI in the United States. METHODS AND RESULTS: We analyzed the 2002-2011 Nationwide Inpatient Sample databases to identify all patients ≥40 years of age with the principal diagnosis of acute myocardial infarction (AMI) and NSTEMI. Logistic regression was used for overall, age-, sex-, and race/ethnicity-stratified trend analysis. From 2002 to 2011, we identified 6 512 372 patients with AMI. Of these, 3 981 119 (61.1%) had NSTEMI. The proportion of patients with NSTEMI increased from 52.8% in 2002 to 68.6% in 2011 (adjusted odds ratio [OR; per year], 1.055; 95% confidence interval [CI], 1.054 to 1.056) in the overall cohort. Similar trends were observed in age-, sex-, and race/ethnicity-stratified groups. From 2002 to 2011, utilization of EIS at day 0 increased from 14.9% to 21.8% (Ptrend<0.001) and utilization of EIS at day 0 or 1 increased from 27.8% to 41.4% (Ptrend<0.001). Risk-adjusted in-hospital mortality in the overall cohort decreased during the study period (adjusted OR [per year], 0.976; 95% CI, 0.974 to 0.978). CONCLUSIONS: There have been temporal increases in the proportion of NSTEMI and, consistent with guidelines, greater utilization of EIS. This has been accompanied by temporal decreases in in-hospital mortality and length of stay.
