Changes in contractility determine coronary haemodynamics in dyssynchronous left ventricular heart failure, not vice versa

Conclusions Acutely increasing coronary flow with adenosine in patients with systolic heart failure does not increase contractility. Changes in coronary flow with biventricular pacing are likely to be a consequence of enhanced cardiac contractility from resynchronization and not vice versa.
