Submaximal effort tolerance as a predictor of all‐cause mortality in patients undergoing cardiac rehabilitation

600 consecutive patients (450 men and 150 women, mean age 65 years) referred to a 12-week outpatient program of cardiac rehabilitation; 37% had a prior myocardial infarction (MI), 44% had a recent percutaneous intervention (PCI), and 39% had history of coronary artery bypass surgery (CABG).
