Abstract
BACKGROUND AND OBJECTIVE: The control of well-known atherosclerotic risk factors represents the optimal strategy in the prevention of acute coronary syndromes. It was the aim of this work to analyze the effects of a long-term cardiac rehabilitation program on the changes of fibrinolysis parameters and plasma lipid profile in coronary patients. DESIGN AND METHODS: The study was carried out in 30 (M/F:22/8, mean age 47 years) survivors of a first acute myocardial infarction (AMI) and in 30 healthy controls who underwent a cardiac rehabilitation program (9 months duration). Samples were taken before, at 3 and 9 months after the beginning of the program to measure: tissue-type plasminogen activator (t-PA) antigen and plasminogen activator inhibitor (PAI-1) activity and antigen. A lipid profile including cholesterol (both HDL and LDL) and lipoprotein(a) was also assessed. The Wilcoxon and Mann-Whitney tests were used for statistical comparisons. RESULTS: There was a marked decrease of functional PAI-1 after 3 and 9 months as compared with baseline in AMI patients (p < 0.01). Results showed a significant increase of HDL-cholesterol (p < 0.01) and decrease of lipoprotein(a) levels after the exercise program (p < 0.01). INTERPRETATION AND CONCLUSIONS: The cardiac rehabilitation program improved fibrinolysis, by reducing the functional levels of PAI-1, and ameliorated the lipid profile by decreasing lipoprotein(a) and increasing HDL-cholesterol in patients with AMI. A long-term cardiac rehabilitation has positive effects on some risk factors for coronary disease.
