Predictors of exercise capacity and adaptability to training in patients with coronary artery disease.

摘要: PURPOSE Systolic left ventricular dysfunction is a weak predictor of exercise tolerance in patients with chronic congestive heart failure. This study aimed to determine physiologic and other predictors effort adaptability training wide variety coronary artery disease. METHODS One hundred seventy-one (group 0) documented disease various degrees were enrolled into medically supervised program for 6 months. six had an ejection fraction greater than 50% 1), 38 between 35% 2), 27 less 3). RESULTS Resting parameters systolic diastolic function did not predict the at any level impairment. Noncardiac factors including age, gender, Broca index, forced vital capacity explained variation peak oxygen uptake group 0. Peak uptake, ventilatory threshold, treadmill time exhaustion increased significantly after all groups. The magnitude improvement these variables was same CONCLUSIONS better entry or months training. A similar degree adaptation seen regardless their dysfunction.
