Exercise Echocardiography in Asymptomatic or Minimally Symptomatic HCM: Exercise Capacity, and Not Rest or Exercise LV Outflow Tract Gradients Predicts Long-Term Outcomes

Study Questions:

What are the predictors of long-term outcome in asymptomatic or minimally symptomatic patients with hypertrophic cardiomyopathy (HCM) who underwent exercise echocardiography, without invasive therapies for relief of left ventricular outflow tract (LVOT) obstruction?
