Myocardial remodeling in patients with chronic heart failure and implanted cardiac contractility modulators

Abstract

Aim. To study the effect of cardiac contractility modulation on reverse remodeling and myocardial function in patients with chronic heart failure (HF) according to echocardiography (EchoCG). Materials and methods. In a group of 40 patients with a combination of chronic HF and atrial fibrillation (AF), the dynamics of standard EchoCG parameters and the effectiveness of myocardial work of the left ventricle (LV) against the background of 12-month therapy of cardiac contractility modulation (CCM) were analyzed. Results. The results obtained indicate a statistically significant positive effect of CCM on LV remodeling parameters and the effectiveness of myocardial work according to EchoCG. Conclusion. Transthoracic echocardiography is the main imaging method and provides great opportunities for evaluating the effectiveness of HF treatment, including non-drug methods such as CCM. Evaluation of LV myocardial function in patients with HF and implanted CCM devices is a promising scientific and practical research method.
