EXERCISE RESISTANCE EFFECT ON ADVERSE REACTION RATE IN HEART FAILURE
ABSTRACT Introduction: Heart Failure is a common disease in the elderly. In the end stage, patients usually accompany a reduction in fat content and lean body mass in addition to heart failure. Objective: Study the exercise resistance effects and adverse reaction rate in patients with heart failure. Methods: 52 patients with chronic heart failure (38 males, age 67 ± 2.2 years) were randomly divided into two groups. According to New York Heart Association Functional Classification, 27 patients with grade II and 25 with grade I was randomly divided. The experimental group was submitted to aerobic exercises under heart rate control for seven months and the control group with no exercise prescription. In the comparison, the 6-minute walk test and a cardiac function test were employed by Agilent 4500 EcoDoppler at a frequency of 2.5MHz. The indices of systolic and left ventricular function were recorded on ECG simultaneously using the improved Simpsons method, and the following indices were measured: left ventricular systolic and end-diastolic; left ventricular ejection fraction; left ventricular diastolic function; early, late peak velocity and its ratio; mitral valve diastole. Results: Compared to the control group, heart rate decreased to different degrees (P < 0.05), exercise endurance increased significantly (P < 0.01), and left ventricular function index improved significantly (P < 0.01). Conclusion: We observed a positive impact of aerobic exercise directed at the rehabilitation of the cardiovascular system and mental health in elderly patients. Evidence Level II; Therapeutic Studies – Investigating the results.
