Insights
Intensive lifestyle changes significantly improved endothelial function and reduced inflammation in coronary artery disease patients. This cardiac lifestyle intervention offers a promising approach to managing cardiovascular health.
Area of Science:
- Cardiology
- Preventive Medicine
- Biochemistry
Background:
- Intensive lifestyle changes can regress atherosclerosis and improve cardiovascular risk. Endothelial dysfunction and inflammation are key markers in atherosclerosis progression.
- The Multisite Cardiac Lifestyle Intervention Program offers a structured approach to lifestyle modification for cardiovascular health.
Purpose of the Study:
- To evaluate the impact of a comprehensive lifestyle intervention on endothelial function and inflammatory markers in individuals with coronary artery disease (CAD) or risk factors.
- To assess changes in brachial artery flow-mediated dilatation (FMD) and serum inflammatory markers after a 12-week intervention.
Main Methods:
- A pilot study involving 27 participants in an experimental group (intensive lifestyle changes: diet, exercise, stress management) and 20 matched controls (standard care).
- Endothelium-dependent brachial artery flow-mediated dilatation (FMD) was measured at baseline and after 12 weeks.
- Serum levels of C-reactive protein (CRP) and interleukin-6 (IL-6) were assessed in the experimental group.
Main Results:
- The experimental group showed a significant improvement in FMD (4.23 to 4.65 mm), while the control group showed a decrease (4.62 to 4.48 mm) (p <0.0001).
- Significant reductions in C-reactive protein (CRP) (2.07 to 1.6 mg/L, p = 0.03) and interleukin-6 (IL-6) (2.52 to 1.23 pg/ml, p = 0.02) were observed in the intervention group.
- These improvements suggest a potential mechanism for the clinical benefits of lifestyle interventions in cardiovascular disease.
Conclusions:
- Intensive lifestyle changes, including diet, exercise, and stress management, significantly enhance endothelial function.
- The intervention effectively reduced key inflammatory markers associated with atherosclerosis, such as CRP and IL-6.
- This study supports lifestyle modification as a critical component in managing and potentially reversing cardiovascular disease processes.
Abstract:
Intensive lifestyle changes have been shown to regress atherosclerosis, improve cardiovascular risk profiles, and decrease angina pectoris and cardiac events. We evaluated the influence of the Multisite Cardiac Lifestyle Intervention Program, an ongoing health insurance-covered lifestyle intervention conducted at our site, on endothelial function and inflammatory markers of atherosclerosis in this pilot study. Twenty-seven participants with coronary artery disease (CAD) and/or risk factors for CAD (nonsmokers, 14 men; mean age 56 years) were enrolled in the experimental group and asked to make changes in diet (10% calories from fat, plant based), engage in moderate exercise (3 hours/week), and practice stress management (1 hour/day). Twenty historically (age, gender, CAD, and CAD risk factors) matched participants were enrolled in the control group with usual standard of care. At baseline endothelium-dependent brachial artery flow-mediated dilatation (FMD) was performed in the 2 groups. Serum markers of inflammation, endothelial dysfunction, and angiogenesis were performed only in the experimental group. After 12 weeks, FMD had improved in the experimental group from a baseline of 4.23 + or - 0.13 to 4.65 + or - 0.15 mm, whereas in the control group it decreased from 4.62 + or - 0.16 to 4.48 + or - 0.17 mm. Changes were significantly different in favor of the experimental group (p <0.0001). Also, significant decreases occurred in C-reactive protein (from 2.07 + or - 0.57 to 1.6 + or - 0.43 mg/L, p = 0.03) and interleukin-6 (from 2.52 + or - 0.62 to 1.23 + or - 0.3 pg/ml, p = 0.02) after 12 weeks. Significant improvement in FMD, C-reactive protein, and interleukin-6 with intensive lifestyle changes in the experimental group suggests > or = 1 potential mechanism underlying the clinical benefits seen in previous trials.
