Optimal left ventricular lead placement for cardiac resynchronization therapy in postmyocardial infarction patients.

摘要

To evaluate at a 12-month follow-up, the clinical and echocardiographic outcomes in postmyocardial infarction (MI) heart failure patients who underwent cardiac resynchronization therapy (CRT) device implantation. A total of 100 patients received a CRT device, and the study population was divided into three groups, according to the site of MI?and left ventricular (LV) lead placed downstream of the ischemic area, as evaluated by echocardiography. At the end of the 12-month follow-up, we reported a general improvement of LV ejection fraction from 28?±?7% to 35?±?9% (p?
