May refine risk stratification in chronic systolic HF; extends echocardiographic predictors but requires prospective validation.
Does systolic mitral annular velocity (Sm) measured with Doppler tissue imaging predict death or heart transplantation in patients with chronic heart failure and LV systolic dysfunction?
Systolic mitral annular velocity measured by Doppler tissue imaging is a strong independent predictor of mortality or need for heart transplantation in patients with chronic heart failure and reduced ejection fraction.
