Abstract
Background and objectives: Cardiovascular disease is one of the most important causes of mortality worldwide. The present study aimed to compare two different cardiac rehabilitation protocols on ATP-binding cassette sub-family G member 1 (ABCG1) lymphocyte expression and blood lipid profile in middle-aged men undergoing coronary artery bypass grafting.
Methods: Forty five middle-aged men who had previously undergone coronary artery bypass surgery were randomly divided into three groups of control (C; n=15), aerobic training (AT; n=15) and combined training (CT; n=15). Blood samples were taken before the first and after the last exercise sessions. After isolation of mononuclear cells using Ficoll and mRNA purification, gene expression changes were examined by real-time PCR. Data were analyzed using one-way ANOVA and Bonferroni post-hoc tests.
Results: Eight weeks of training intervention resulted in a significant increase in ABCG1 expression as well as a significant decrease in plasma levels of LDL, triglyceride and total cholesterol in both training groups. However, there was no significant difference between the AT and CT groups. In addition, high-density lipoprotein was significantly increased in the AT and CT groups.
Conclusion: Both AT and CT can increase plasma LDL and increase ABCG1 expression and HDL concentrations, indicating the positive effects of both interventions on the prevention of atherosclerosis.

Abstract
Background: Significant economic consequences can lead to various problems and complications, including medical complications. Coronary artery disease (CAD), a serious health threat with increasing prevalence, is a major cause of death and mortality worldwide. This study aimed to investigate the effects of a special training program on cytochrome P450 (CYP) gene expression and reactive oxygen species (ROS) levels in patients with coronary artery bypass surgery.
Methods: This semi-experimental study was conducted on 16 patients who underwent coronary artery surgery in Babol City, Iran. The patients were selected using a random sampling method and divided into 2 groups: experimental and control groups. The experimental group engaged in an exercise program consisting of 3 sessions per week for a duration of 8 weeks. The expression levels of CYP and ROS genes were measured by the real-time polymerase chain reaction (PCR) method. The analysis was performed by comparing covariances and means.
Results: ROS gene expression levels significantly decreased in the experimental group than in the control group (P=0.003). However, there was no significant difference in P450 levels between the experimental and control groups (P=0.99).
Conclusion: Special exercises reduced ROS expression and increased P450 expression in patients who had coronary bypass surgery. There is a probability that special exercises, can effectively prevent heart damage by increasing antioxidant capacity and reducing ROS.
