摘要
Objectives: We evaluated the effects of lifestyle modification (LM) on lipid profile, oxidative stress and serum-stimulated human coronary artery endothelial cell (HCAEC) viability in coronary artery disease (CAD) patients after 6 months. Design and methods: Thirty patients with CAD were randomly assigned to LM intervention (n=15) and usual care control (n=15) groups. LM-intervened patients were instructed to consume low-fat, high-antioxidants and fiber diets. Moderate exercise and stress management were also advised. Group support to maintain patients' compliance was applied. Results: Serum cholesterol, triglyceride, oxidized LDL and protein carbonyl were decreased in LM group. Serum triglyceride was increased in control group. HCAEC viability was increased, while intracellular reactive oxygen species was decreased, by serum from the LM group. Conclusion: LM is capable of improving lipid profile, reducing oxidative stress and increasing HCAEC survival in the patients with CAD, hence lowering a risk for the future cardiovascular event.
