Abstract:
Objective To investigate the effect of cardiac resynchronization therapy on improving heart function and reversing left ventricular remodeling in chronic heart failure patients. Methods Eleven patients with NYHA class Ⅲ to Ⅳ heart failure, ejection fraction ≤35% and QRS duration ≥130 ms were implanted synchronous biventricular pacemaker. Serial assessment was performed before and up to 1-36 months after pacing. Results There were significant improvement of LVEF、 LVFS; and decrease in MR、 LVED and QRS duration. The NYHA class of heart function was improved from Ⅲ-Ⅳ to Ⅰ-Ⅱ. Six-minute hall walk distances were also improved. Conclusion For patients with NYHA class Ⅲ to Ⅳ heart failure and ventricular conduction delay, cardiac resynchronization therapy could reverse left ventricular remodeling and improve heart function.
