Randomized clinical trials have firmly established the role of cardiac resynchronization therapy (CRT) in chronic heart failure patients in New York Heart Association (NYHA) class III or IV who have left ventricular dysfunction and a prolonged QRS complex. CRT improves symptoms, reduces the need for hospitalizations, and improves survival by reversal of left ventricular remodelling and by slowing of disease progression.
In these CRT trials, patients were selected on the basis of the degree of heart failure. COMPANION1 included 86% class III and 14% class IV patients. CARE-HF included 94% NYHA class III and 6% class IV patients.2 Thus, the data on the beneficial effects of CRT, based on large trials, are restricted to class III and to a
