ABSTRACT
Objective: To explore the inlfuence of diastolic iflling pattern on cardiac resynchronization therapy (CRT) in patients with ischemic cardiomyopathy. Methods: A total of 61 patients with ischemic cardiomyopathy received CRT in our hospital from 2012-03 to 2014-03 were studied. According to pre-CRT diastolic iflling pattern, the patients were divided into 2 groups:Non-restrictive iflling (NRF) group, n=36 and RF group, n=25. All patients were followed-up for 12 months, based on NYHA classiifcation, CRT efifcacy was assessed by echocardiography;the endpoints included re-hospitalization for heart failure or cardiac death. Kaplan-Meier survival curve was used to assess the prognosis. Results: ①NRF group had CRT response rate at 66.7%(24/36) which was higher than RF group 28.0%(7/25), (χ2=8.826, P=0.003);the post-operative NYHA classiifcation, LVEF, FS, LVEDV and LVESV were signiifcantly improved, all P Conclusion: Diastolic iflling pattern affected CRT efifcacy in patients with ischemic cardiomyopathy;NRF patients were more beneifciary for CRT, while RF patients had lower response to CRT which associated to poor prognosis.
