Abstract
Objective To observe the efficacy of cardiac resynchronization therapy( CRT ) in the treatment of patients with mild chronic heart failure. Methods Seven dilated cardiomyopathy patients with mild chronic heart failure and left bundle branch block received CRT,and followed up for 12 months. Doppler echocardiograms were recorded at baseline,before hospital discharge,and on the 12th month after operation. Results There were no patients hospitalized again for heart failure during the 12-month follow-up,and the patients' exercise capacity was improved. Compared with baseline,left ventricular end-diastolic dimension( LVEDD ) and mitral regurgitation( MR ) were significantly decreased ( P <0.05 ),while left ventricular ejection fraction( LVEF ),left ventricular end-systolic dimension( LVESD ) and left ventricular fraction shortening( LVFS ) did not change before hospital discharge( P > 0. 05 ). On the 12th month after operation, LVEF and LVFS were significantly increased( P < 0.05 ) while LVESD, LVEDD and MR were significantly decreased compared with baseline( P < 0. 05 ). The change of LVEDD on the 12th month after operation was positive correlated with QRS duration at baseline( P <0.05 ). Conclusion CRT can improve ventricular structure and function in dilated cardiomyopathy patients with mild chronic heart failure and left bundle branch block.关键词
