Abstract

Objective: To observe the prognostic influences of the cardiac rehabilitation (CR) program in Korean acute myocardial infarction (AMI) patients during the first 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. The 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. The 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 first year.

Keywords: Event-free survival rate; Myocardial infarction; Recurrence rate; Rehabilitation; hs-CRP.
