E/e′ ratio and outcome prediction in hypertrophic cardiomyopathy: the influence of outflow tract obstruction

Abstract

Assessment of E/e' is useful for risk stratification in HCM patients. Nevertheless, the predictive power is confounded by dynamic LVOT obstruction. Higher E/e' predicts worse clinical outcomes in non-obstructive HCM and in labile/obstructive after myectomy.
