Cases Analysis Of Application Of Cardiac Resynchronization Therapy In Patients With Refractory Heart Failure

Objective:Summarize the clinical experience and the effectiveness of cardiac rsynchronization therapy.Methods:Retrospective analysis was conducted to the clinical data of 8 patients, who were all with refractory heart failure and received cardiac resynchronization therapy. In the basic of optimal drug therapy, all patients accepted cardiac resynchronization therapy and followed up after the operation. They all received routine 12-lead electrocardiogram, heart X-ray, echocardiography,6 Minutes Hall Walking Test(6MHWT) and clinical cardiac function evaluation etc before and after the operation. Then we make a statistical analysis of the data.Results:8 patients were all successfully completed a pacemaker implantation in the basic of optimal drug therapy. Clinical cardiac function was all obviously improved. The 6 minutes hall walking distance was increased and QRS duration was decreased. The cardiac indexes in echocardiography were all improved. The hospitalization event for heart failure was significantly decreased. Conclusions:Cardiac resynchronization therapy can improve cardiac function in patients with refractory heart failure, reverse ventricular remodeling and improve the quality of life of the patients and decrease readmission rate.
