Clinical versus echocardiographic parameters to assess response to cardiac resynchronization therapy

Am J Cardiol. 2006 Jan 15;97(2):260-3. doi: 10.1016/j.amjcard.2005.08.030. Epub 2005 Nov 28.


Currently, a clear definition of response to cardiac resynchronization therapy (CRT) is still lacking, and clinical and echocardiographic end points are used. It is also unclear whether patients with clinical responses also improve in echocardiographic end points (and vice versa). To better understand and define response to CRT, the relation between improvement in clinical and echocardiographic parameters was evaluated in 144 patients.
