Cumulative rate of the composite end-point (death plus hospitalisation for heart failure -HF-) in patients with left ventricular ejection fraction (LVEF) <35 % vs. patients with LVEF 35–40 % (upper panel) calculated according to the Kaplan–Meier method. Similarly, the lower panel shows cumulative rate of the composite end-point in patients with 2–3 diseased vessels vs. one-diseased vessel (referring to the number of coronary lesions at angiography). Follow up stops at 28 months
