Values are expressed as number (n) of patients, mean ± standard error of the mean (SE) or mean with minimum (min) and maximum (max) values. LVEF, left ventricular ejection fraction determined by echo-cardiography; STEMI, ST-elevation myocardial infarction; PCI, percutaneous coronary intervention; CABG, coronary artery by-pass grafting; NTG, long-acting nitrate preparation.
