FIELD: medicine; cardiology.
SUBSTANCE: transthoracic echocardiography is performed, the level of blood pressure is measured according to the Korotkov’s method. Based on these data, as well as indicators of global longitudinal deformation the value of the global constructive work of the LV myocardium (GCW) is determined. With a GCW value <762 mmHg, %, in patients with chronic heart failure with reduced left ventricular ejection fraction and atrial fibrillation a high risk of adverse cardiovascular events during the next 12 months of follow-up after implantation of the cardiac contractility modulation system is predicted.
EFFECT: method provides improved accuracy of predicting adverse cardiovascular events.
