Abstract

The impact of exercise intolerance on quality of life among patients with congestive heart failure (CHF) is obvious. The purpose of this study was to explore exercise tolerance and related factors among patients with CHF. An explored-correlated design was used to guide the study. Forty-nine subjects who met the selection criteria were selected from a medical center of Taipei by purposive sampling. Data was collected by the treadmill exercise tests, with a fixed protocol and a graded protocol.
Research results were shown as following: (1).The average peak VO2 (exercise intensity tolerance) was 4.56 METs. The average duration of exercise tolerance was 768.55 seconds, 1717.04 seconds, and 1923.84 seconds at 50% heart rate reserve (HRR), 90% HRR, and the end of the test, respectively. (2).A significant relationship between age and duration of exercise tolerance at 50% HRR was observed. (3).The New York Heart Association (NYHA) function class, intensity tolerance of exercise and duration tolerance of exercise were significantly correlated with each other. The findings of the study proved that the exercise testing is safe, feasible, and effective for evaluation of exercise tolerance, and should be recommended to patients with stable congestive heart failure.
