OBJECTIVE: Exercise training programs have been proposed as adjuncts to treatment of heart failure. The effects of a 3-month-exercise-training-program with 3 exercise sessions per week were assessed in patients with stable systolic chronic heart failure. METHODS: We studied 24 patients with final left ventricle diastolic diameter of 70 +/- 10 mm and left ventricular ejection fraction of 37 +/- 4%. Mean age was 52 +/- 16 years. Twelve patients were assigned to an exercise training group (G1), and 12 patients were assigned to a control group (G2). Patients underwent treadmill testing, before and after exercise training, to assess distance walked, heart rate, systolic blood pressure, and double product. RESULTS: In G2 group, before and after 3 months, we observed, respectively, distance walked 623 +/- 553 and 561 +/- 460 m (ns); peak heart rate 142 +/- 23 and 146 +/- 33 b/min (ns); systolic blood pressure 154 +/- 36 and 164 +/- 26 mmHg (ns); and double product 22,211 +/- 6,454 and 24,293 +/- 7,373 (ns). In G1 group, before and after exercise, we observed: distance walked 615 +/- 394 and 970 +/- 537 m (p < 0.003); peak heart rate 143 +/- 24 and 143 +/- 29 b/min (ns); systolic blood pressure 136 +/- 33 and 133 +/- 24 mmHg (ns); and double product 19,907 +/- 7,323 and 19,115 +/- 5,776, respectively. Comparing the groups, a significant difference existed regarding the variation in the double product, and in distance walked. CONCLUSION: Exercise training programs in patients with heart failure can bring about an improvement in physical capacity.
