| Popis: | In 183 consecutive patients with recent, uncomplicated myocardial infarction, the following variables were associated with 4-year cardiac death: haemodynamic decompensation with exercise (P = 0.01), left ventricular ejection fraction at rest (P = 0.004) and at peak exercise (P = 0.003), persistent ST segment elevation at rest in the area of infarction (P = 0.004), exercise-induced ST segment elevation (P=0.02), and late aneurysmal evolution (P=0.01). Exercise left ventricular ejection fraction was the sole variable selected by Cox regression analysis as an independent predictor of cardiac death. In 40 patients with ST segment elevation at rest, left ventricular ejection fraction was 42± 17% at rest and 40 ± 18% at peak exercise, versus 52 ± 12% and 52 ± 14% in the remaining patients (both P |
