Abstract

Purpose

To determine the impacts of cardiac rehabilitation on exercise capacity, quality of life (QOL), and functional status in patients with coronary artery disease (CAD).

Design

Self-controlled clinical trial.

Methods

CAD patients with mild to moderate left ventricular dysfunction participated in an exercise-based rehabilitation program for eight consecutive weeks. Subjects underwent an exercise test before and 8 weeks after rehabilitation. QOL was assessed with the SF-36 questionnaire. Functional status was assessed in terms of sleep time, walking, cycling, exercise, and working duration.

Findings

Seventy patients (age = 57.5 ± 10.2 years, 77.1% male) were studied. After rehabilitation, peak exercise capacity increased from 8.00 ± 2.56 to 10.08 ± 3.00 METs (p < .001) and exercise duration increased from 14.17 ± 5.27 to 17.21 ± 5.85 minutes (p < .001). Patients' QOL improved in physical and psychological dimensions (p < .05). Cycling, walking, and exercising status significantly increased after the study (p < .05).

Conclusions

Cardiac rehabilitation improves exercise capacity, QOL, and functional status of CAD patients with mild to moderate left ventricular dysfunction.

Clinical Relevance

Cardiac rehabilitation practitioners should encourage patients to attend to and be compliant in the rehabilitation programs.
