ABSTRACT
OBJECTIVE:
To examine the effect and safety of cardiac rehabilitation (CR) program in high-risk cardiac patients and compare these results to those of control CR participants without high-risk criteria.METHODS:
A total of 12 high-risk cardiac patients were recruited as subjects. The high-risk criteria were advanced heart failure with left ventricular ejection fraction (LVEF) of less than 30%, a recent history of cardiac arrest or dangerous arrhythmia, and cardiac device insertion. Another 12 CR participants without any high-risk criteria mentioned above were recruited as controls. Both groups underwent 6 to 8 weeks of CR exercise training. Exercise tolerance tests were performed before and after completion of the CR program. After CR completion, both groups were evaluated and their results were compared.RESULTS:
After completion of the CR exercise program, both groups showed significant increases in peak oxygen uptake (VO(2peak)) and LVEF. In the control group (n=12), VO(2peak) increased from 25.9 to 31.8 mL/kg/min (changing rate, +21.4%±22.1%) and LVEF increased from 56.1% to 59.1% (changing rate, +5.3%±8.4%). In the high-risk group (n=12), VO(2peak) increased from 16.8 to 21.0 mL/kg/min (changing rate, +28.6%±21.4%) and LVEF increased from 26.1% to 29.4% (changing rate, +16.1%±12.9%). There was no serious cardiovascular event during all exercise hours.CONCLUSION:
High-risk cardiac patients who completed a supervised CR program demonstrated significant improvements in VO(2peak) and LVEF without any serious cardiovascular event. The improvement rate was similar to that of control group.
