THE ROLE OF ECHOCARDIOGRAPHIC RESEARCH IN DIAGNOSIS AND PREDICTION OF HEART FAILURE AT THE PRESENT STAGE
The prediction of cardiovascular complications remains a challenge in patients with heart failure (CH). Despite the development of such visualization methods as computer tomography of coronary vessels, positron emission tomography, single-photon emission computer tomography, in the evaluation of structural pathology of the heart, the function of the left and right ventricles, echocardiography (EchoCG) is the primary role. Left ventricular ejection fraction (LVEF) was correlated with an increased risk of unwanted cardiovascular events. However, heart failure with a preserved ejection fraction in recent years is becoming more common. Diastolic heart failure is associated with a mortality risk similar to heart failure with a reduced ejection fraction [1]. Diastolic dysfunction is often difficult to assess, because it is necessary to quantify several parameters and coordinate them with a clinical assessment of the patient's condition. The article presents modern possibilities of the echocardiographic method in the evaluation of myocardial function.
