Overall, based on recent studies demonstrating a lack of improvement in mortality in some patients with dilated cardiomyopathy, the CRT-P/CRT-D implantation ratio has been increasing across Europe. Objective: To evaluate the evolution of the CRT-P/CRT-D implantation ratio and to evaluate the impact on mortality of dilated cardiomyopathy (DCM) patients who underwent resynchronization therapy.engjournal article10.1093/eurheartj/ehz747.0580
