Abstract
Objective
To assess short-term and long-term effects of cardiac resynchronization therapy (CRT) in heart failure patients.
Methods
We continuously assessed forty-five end-stage heart failure patients. NYHA grade, left ventricular diastolic diameter (LVED), left ventricular ejection fraction (LVEF) and B-type natriuretic peptides (BNP) before cardiac resynchronization therapy and at six months, one year, two years after cardiac resynchronization therapy were evaluated.
Results
Compared to the results before cardiac resynchronization, six months, one year and two years after CRT, NYHA grade, LVEF, LVED, BNP improved significantly (all P 0.05).
Conclusions
CRT could improve the short-term and long-term myocardial function of hear failure patients.
