A Study to Compare Post-exercise Treadmill versus Supine Bicycle Exercise Left Ventricular Outflow Tract Gradients Assessed by Echocardiography in Hypertrophic Cardiomyopathy

Overview

Información sobre este estudio

Exercise testing is routinely utilized in the evaluation of patient’s with hypertrophic cardiomyopathy to assess exercise capacity and also to evaluate the presence and severity of obstruction with an echocardiogram. Identifying significant obstruction is important in order to determine who could gain benefit from more invasive therapies like surgery.

There are several different exercise protocols available but it is not known which is the best method to assess the presence and severity of obstruction in hypertrophic cardiomyopathy. The purpose of this study is to determine which exercise protocol (supine bike or exercise treadmill) is better in these regards.
