p-value: p=<0.05 or 0.01
Rehabilitation training starting 3 days post-PCI for 3 months significantly improves exercise tolerance, relieves angina, and amends ischemic ECG features.
Supports early post-PCI rehabilitation in routine care; extends RCT evidence for functional gains in coronary disease.
The aim of this present study was to investigate the effects of training on exercise tolerance of patients with coronary heart disease after percutaneous coronary intervention. Fifty-seven cases of coronary heart disease after percutaneous coronary intervention were divided randomly into the rehabilitation training group (26 cases) and control group (31 cases). Patients in the rehabilitation training group received rehabilitation training at different stages and exercise intensities 3 d after percutaneous coronary intervention for 3 months. The heart rate, blood pressure, ECG changes in treadmill exercise test, and the frequency of anginal episodes were observed. The results showed that NST and ΣST of ECG and the frequency of anginal episodes were significantly reduced in the rehabilitation training group. In addition, exercise tolerance was improved and the total exercise time was lengthened in these patients. Moreover, ST segment depression time and emergence time of angina with exercise were also lengthened compared with controls (P < 0.05, or 0.01). However, the heart rate and blood pressure before and after exercise of the two groups were similar. The study indicated that rehabilitation training could significantly relieve angina, amend ischemic features of ECG, and improve exercise tolerance of coronary heart disease patients after percutaneous coronary intervention.

Jin et al. (2012) conducted an RCT in Coronary heart disease after percutaneous coronary intervention (n=57). Rehabilitation training vs. Control group was evaluated on Exercise tolerance, ECG changes, and frequency of anginal episodes (p=<0.05 or 0.01). Rehabilitation training for 3 months after percutaneous coronary intervention significantly improved exercise tolerance and reduced anginal episodes compared with controls (P<0.05 or 0.01).
