Insights
Cardiac rehabilitation improves life quality in coronary heart disease patients by enhancing endothelial function through exercise and lifestyle changes. Further research is needed to explore new interventions for better endothelial protection.
Area of Science:
- Cardiology
- Vascular Biology
- Rehabilitation Medicine
Background:
- Coronary heart disease (CHD) significantly impacts patient morbidity and quality of life.
- Endothelial function is a critical marker for CHD progression.
- Traditional cardiac rehabilitation (CR) includes exercise, medication, and smoking cessation, but emerging programs' effects on endothelial function are less understood.
Purpose of the Study:
- To review the endothelium-beneficial effects of various CR pathways in CHD patients.
- To summarize the cellular and molecular mechanisms underlying CR's role in endothelial function.
- To identify gaps and suggest future research directions for enhancing endothelial protection in CHD.
Main Methods:
- Literature review of existing studies on cardiac rehabilitation and endothelial function.
- Analysis of cellular and molecular mechanisms, including nitric oxide bioavailability, endothelial progenitor cells (EPCs), oxidative stress, endothelial-dependent hyperpolarizing factors, and inflammation.
- Examination of both traditional and emerging CR interventions.
Main Results:
- Exercise training and lifestyle modifications in CR enhance nitric oxide bioavailability, increase circulating EPCs, and reduce oxidative stress.
- Preservation of endothelial-dependent hyperpolarizing factors and inflammatory suppression also contribute to improved endothelial function.
- Key mechanisms involve increased nitric oxide, more EPCs, and reduced oxidative stress.
Conclusions:
- Cardiac rehabilitation, particularly exercise and lifestyle interventions, offers significant endothelium-protective benefits in coronary heart disease.
- Further well-designed clinical trials and experimental studies are necessary to fully elucidate the mechanisms and optimize new CR strategies for endothelial health.
- Standardized CR programs and assessment methods are crucial for advancing research in this field.
Abstract:
Cardiac rehabilitation, a comprehensive exercise-based lifestyle and medical management, is effective in decreasing morbidity and improving life quality in patients with coronary heart disease. Endothelial function, an irreplaceable indicator in coronary heart disease progression, is measured by various methods in traditional cardiac rehabilitation pathways, including medicinal treatment, aerobic training, and smoking cessation. Nevertheless, studies on the effect of some emerging cardiac rehabilitation programs on endothelial function are limited. This article briefly reviewed the endothelium-beneficial effects of different cardiac rehabilitation pathways, including exercise training, lifestyle modification and psychological intervention in patients with coronary heart disease, and related experimental models, and summarized both uncovered and potential cellular and molecular mechanisms of the beneficial roles of various cardiac rehabilitation pathways on endothelial function. In exercise training and some lifestyle interventions, the enhanced bioavailability of nitric oxide, increased circulating endothelial progenitor cells (EPCs), and decreased oxidative stress are major contributors to preventing endothelial dysfunction in coronary heart disease. Moreover, the preservation of endothelial-dependent hyperpolarizing factors and inflammatory suppression play roles. On the one hand, to develop more endothelium-protective rehabilitation methods in coronary heart disease, adequately designed and sized randomized multicenter clinical trials should be advanced using standardized cardiac rehabilitation programs and existing assessment methods. On the other hand, additional studies using suitable experimental models are warranted to elucidate the relationship between some new interventions and endothelial protection in both macro- and microvasculature.
