Methods: A total of 110 elderly patients with coronary heart disease and chronic heart failure according to random data table were divided into control group (n=54) and observation group (n=56). The patients in control group were treated with conventional drug, and patients in the observation group received conventional drug combined with aerobic exercise training. Before and after treatment, levels of red blood cell parameters, vascular endothelial function and cardiac function indexes were compared between the two groups. Results: Before treatment, the difference of HCT, RDW, RBC, NO, ET-1, LVEF, LVEDD and LVESD levels in the two groups were not significantly. After treatment, HCT and RBC levels in two groups were no statistically significant difference;The levels of RDW, ET-1, LVEDD and LVESD in observation group were significantly lower than those in this group before treatment, and significantly lower than those in the control group after treatment;The levels of NO and LVEF in two groups were significantly higher than those in the group before treatment, and levels of NO and LVEF in the observation group were significantly higher than those in control group after treatment. Conclusion: The clinical effect of aerobic exercise training combined with conventional drug in treatment of senile coronary heart disease with chronic heart failure was significant, which can effectively increase the RDW level of patients, improve vascular endothelial function and heart function, it has important clinical value.展开更多
