Can we “ScREEN” response to cardiac resynchronization therapy by a simple score?

Cardiac resynchronization therapy (CRT) is an established treatment in symptomatic patients with heart failure with a prolonged QRS duration and reduced left ventricular ejection fraction (LVEF) despite optimal medical therapy to improve symptoms and reduce morbidity and mortality [1]. However, approximately one-third of the patients do not benefit from this therapy [2 –4]. Many studies have been published of possible predictors of CRT response, such as age, gender, etiology of cardiomyopathy, atrial fibrillation, QRS duration, QRS morphology, chronic kidney disease, left ventricular end-diastolic volume (LVEDV), LVEF, prior heart failure hospitalization, and Ne w York Heart Association (NYHA) functional class [3,4].
