Does Cardiac Resynchronization Therapy Benefit Patients With Ischemic and Non-Ischemic Cardiomyopathy Similarly?

Randomized clinical trials (RCTs) show that cardiac resynchronization therapy (CRT) can reduce mortality and hospitalization rates in patients with heart failure due to left ventricular systolic dysfunction and intraventricular conduction delay (IVCD) (QRS ≥ 120 ms) when used in addition to optimal medical therapy.
