BACKGROUND: Early physical therapy plays important role in improving functional capacity, activities of daily life, and quality of life after acute myocardial infarction. OBJECTIVE: We aimed to describe effects of 4 weeks physical therapy program after acute myocardial infarction. METHODS: In our study, 20 men participated in physical therapy program for 14 days after PCI surgery. The patients were diagnosed with myocardial infarction and aged 56.45±8.1. Their BMI was 27.39±3.61and waist circumference was 98±9.28. Exercise program was scheduled 3 times a week with each session consisting of 34-70% intensity exercises for 60 minutes. Exercise type is aerobic (warming up for 10 minutes, walking, bicycling and cooling down stretch for 10 minutes). RESULTS: For the 6-minute walking test (p=0.01) there was significant difference between before and after 4 weeks’ exercise program. CONCLUSION: The hospital based 4 weeks exercise program improved the functional capacity for pci patients.
