Angiographic and clinical characteristics associated with the development of Q-wave and non-Q-wave myocardial infarction in the thrombolysis in myocardial infarction (TIMI) 14 trial.

Abstract

In the absence of thrombolytic therapy, patients with non-Q-wave myocardial infarction (MI) have previously been shown to have lower long-term mortality rates than patients with Q-wave MI. The goal of our study was to examine the angiographic and clinical differences between non-Q-wave MI and Q-wave MI in patients with ST elevation MI (STEMI) in the era of thrombolytic and combination therapy of thrombolytics plus glycoprotein IIb/IIIa inhibitors.
