Predictors of 30-day and 1-year mortality after primary percutaneous coronary intervention for ST-elevation myocardial infarction.

Abstract：

OBJECTIVE:Predictors of 30-day mortality may differ from predictors of mortality at 1 year among 30-day survivors of ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). We aimed to evaluate the predictors of 30-day and 1-year mortality in unselected patients with STEMI treated with PCI. METHODS:Individual patient data from 4732 patients with STEMI, who were treated with primary PCI during an 11-year study period, were recorded prospectively. Patient characteristics, 30-day, and 1-year outcome were evaluated. RESULTS:At 30-day follow-up, 219 patients (4.6%) died; and out of the 4513 30-day survivors, 109 patients (2.8%) died at 1 year. Patients who died were older, had a higher risk profile. Higher rates of Killip class greater than 2 on admission, multivessel disease, and, more often, lower left ventricular ejection fraction were observed in patients who died. Mortality rate was 7.6% at 30 days among the females when compared with 3.7 among the males, P value less than 0.001. Age and sex-adjusted multivariate analysis revealed that previous myocardial infarction, diabetes, Killip class greater than 2, post-PCI thrombolysis in myocardial infarction flow less than 3, and left ventricular ejection fraction less than 30% were strong predictors of both 30-day and 1-year mortality. However, multivessel disease, anterior myocardial infarct location and in-hospital reinfarction, ischemic time, and pre-PCI thrombolysis in myocardial infarction flow less than 3 were particularly strong predictors of 30-day mortality. CONCLUSION:Despite the fact that most characteristics of 30-day and 1-year mortality among 30-day survivors are similar, we found that variables that affect mortality beyond the acute phase may not necessarily be the same as those that influence early mortality.
