Objective: To observe the prognostic influences of the cardiac rehabilitation (CR) program in Korean acute myocardial infarction (AMI) patients during the fi rst year after an occurrence of the disease.
Method: A total of 141 AMI patients who underwent percutaneous coronary intervention (PCI) were recruited consecutively for this study and divided into the CR group and the control group. Th e CR group completed the phase 2 CR program in the hospital for a period of 6-8 weeks and maintained self-exercise in their community by exercise prescription for a year after AMI. We performed a prospective comparison of the patients’ demographic data, high sensitive C-reactive protein (hs-CRP) level after the 4-month CR program, and the rate of recurrence (AMI, re-hospitalization, positive coronary angiogram, needed revascularization procedure, or death) between the two groups.
Results: Compared to the control group (0.33±0.48 mg/dl), the hs-CRP level was lower in the CR group (0.18±0.32 mg/dl) after 4 months of exercise. Th e recurrence rate was lower (10%, 7/69) in the CR group, compared to the control group (24%, 17/72, p<0.05). The number of disease-free days was larger in the CR group (354±38.34), compared to the control group (316±99.96, p<0.05). In a comparison of statistical methods used for testing the equality of two survivor distributions, the CR group showed a lower recurrence rate than the control group (p<0.05).
Conclusion: Participation in the CR program designed for AMI patients who underwent PCI-induced normalization of the serum hs-CRP level and lowering of the recurrence rate by 14% during the fi rst year.
