Key result
Cardiac resynchronisation therapy elicited a clinical or echocardiographic response in 70.5% of heart failure patients, with responders showing improved survival over non-responders (96.2% vs 45.5%, p<0.001).

LV diameter and diastolic pattern may aid CRT responder identification; leaves open whether they refine selection in prospective trials.
Gradaus et al. (2007) conducted an observational in Heart failure (n=122). Cardiac resynchronisation therapy (CRT) was evaluated on Improvement by ≥1 NYHA functional class or reduction of left ventricular end-systolic volume by ≥10%. Cardiac resynchronisation therapy elicited a clinical or echocardiographic response in 70.5% of heart failure patients, with responders showing improved survival over non-responders (96.2% vs 45.5%, p<0.001).
