Effect of an Aerobic Exercise Session on Cardiovascular and Autonomic Parameters of Adults With Hypertrophic Cardiomyopathy
Sponsor: Instituto de Cardiologia do Rio Grande do Sul
Summary
Hypertrophic cardiomyopathy is a genetic heart disease with symptoms that may include dyspnea and fatigue predominantly on exertion, with or without chest pain, palpitations, syncope/presyncope and sudden cardiac death, mostly in young individuals, often without symptoms. Due to the higher cardiovascular risk described for individuals with hypertrophic cardiomyopathy, it is extremely important to create non-pharmacological strategies that can minimize the evolution of cardiovascular risk factors found in this population. The objective of the study will be to evaluate the effect of an aerobic exercise session on the ratio between the low frequency (LF) and high frequency (HF) bands of heart rate variability, endothelial function through flow-mediated dilation and systolic and diastolic blood pressure during the 24-hour period in adult individuals with hypertrophic cardiomyopathy. The study design will be a randomized crossover clinical trial with individuals aged 18 to 59 years, of both sexes, randomized by lottery and divided into two groups: Exercise group and control group without exercise. An exercise stress test will be performed and on a new date the individuals will perform a supervised session of moderate-intensity aerobic exercise on a horizontal stationary bicycle for 50 minutes or will remain seated in an air-conditioned room for the same period of time. Subsequently, the procedures will be crossed. It is expected to find improvements in the parameters of endothelial function, autonomic modulation and 24-hour blood pressure in adult individuals with non-obstructive hypertrophic cardiomyopathy undergoing a session of aerobic physical exercise when compared to a control session without exercise.
