Taking part in a six-month tai chi (TC) exercise-based cardiac rehabilitation program may lead to a better prognosis for cardiac events in patients with coronary artery disease (CAD). Fifty-four Taiwanese patients were randomised to usual care or usual care plus TC (weekly 90 minute sessions of Yang-style TC) for six months. A treadmill exercise test was performed to evaluate their exercise test responses at baseline and six months. The TC exercise-based cardiac rehabilitation programme was associated with improved peak RPP (rate pressure product) and RPP reserve during exercise testing in patients with CAD. The improvement over time in two prognostic factors of cardiac events was found to be significantly different between the TC and control groups.
