Does Cardiac resynchronization therapy reduce adverse clinical events in patients with heart failure based on QRS duration?
CRT effectively reduces adverse clinical events in heart failure patients with a QRS duration of ≥150 ms, but lacks benefit in those with a QRS <150 ms, which is critical for patient selection.
Cardiac resynchronization therapy was effective in reducing adverse clinical events in patients with heart failure and a baseline QRS interval of 150 milliseconds or greater, but CRT did not reduce events in patients with a QRS of less than 150 milliseconds. These findings have implications for the selection of patients for CRT.
