Abstract

To retrospectively analyze the efficacy of polypharmacy conventional drugs and aerobic exercise diagnosed in the treatment of chronic heart failure is the objective of the study. From January 2021 to June 2022, 106 patients with chronic heart failure were hospitalized in cardiovascular department of Zhejiang hospital. The control group was taken conventional anti-heart failure drug treatment. On the basis of the control group, the research group implemented 12 w of scientific aerobic exercise and monitored the patient’s exercise status and treatment effect on the mobile phone exercise applications. After receiving medication and 12 w of aerobic exercise training, left ventricular systolic dysfunction and left ventricular diastolic dysfunction in the study were lower than those in the control group and the left ventricular ejection fraction increased significantly compared to the study group and differences between the two groups was statistically significant (p<0.05). The red blood cell distribution width and the opposite association were seen in the subjects studied using New York heart association grade and left ventricular ejection fraction in cardiac function was determined. Manifestations of red blood cells were negatively associated with the maximal oxygen consumption in exercise capacity. Maximum power and time of exhaustion were negatively correlated. The two different groups have marked differences in the left ventricular ejection fraction and New York heart association classification, improvement of maximal oxygen consumption and time of exhaustion (p<0.05). Failure in the application of anti-heart failure drug therapy combined with moderate aerobic exercise application in long-term heart failure patients can effectively reduce the red blood cell distribution width and improve the patient’s health. Cardiac function and exercise capacity, and aerobic exercise can effectively reduce the degree of myocardial damage, improve exercise tolerance, and promote medical recovery of heart failure patients.
