چکیده
Objectives. To develop an algorithm for determining the remodelling of heart in chronic failure with preserved ejection fraction (HFpEF). Material and methods. In 2017-2019, on basis Healthcare Institution «1st City Clinical Hospital» Minsk, a one-stage (cross-sectional) comparative clinical instrumental study stratified random sample consisting 175 patients aged 71.0 (64.0; 78.0) years was performed. 2019-2021, State «Minsk Scientific-Practical Center Surgery, Transplantation Hematology» performed independent reproductive (examination) sample, which included 129 64.5 (58.0; 70.0) years. Criteria inclusion study: sinus rhythm; essential arterial hypertension; ischemic disease; HFpEF; presence voluntary informed consent patient to participate study. Exclusion criteria: primary mitral regurgitation, stenosis, valve repair or replacement, congenital defects, cardiomyopathies, acute respiratory diseases. Echocardiography 2D Speckle Tracking were using ultrasound devices Siemens Acuson S1000 (Germany), Vivid E9 (GE Healthcare, USA). Results. An HFpEF is based concept comprehensive, targeted echocardiographic assessment leading risk factors, pathofunctional mechanisms development, structural, functional abnormalities, intracardiac pulmonary hemodynamics, contains scientifically signs characterized by high diagnostic efficiency. The application echocardiography technology aimed at subthreshold systolic ventricular dysfunction, mechanical dispersion myocardial dyssynergy. Conclusions. developed reproducibility accuracy (93.8%), as has been shown examination makes it possible recommend its practical use determination HFpEF.

Atrial remodelling in heart failure: recent developments and relevance for heart failure with preserved ejection fraction
As specialized compartments of the heart, the atria feature unique mechanical and structural properties that differ considerably from those of the ventricular myocardium. Beyond their contribution to cardiac output as a reservoir, conduit, and booster pump at different phases of the cardiac cycle, the atria determine heart rhythm, regularity, and rate (chronotropy). They also function as mechan...

متن کاملHeart Failure With Preserved Ejection Fraction
Symptomatic heart failure, despite preserved left ventricular (LV) ejection fraction, is a well-recognized phenomenon. This manifestation of diastolic dysfunction is associated with increased morbidity and mortality and can be attributed to a variety of pathogeneses, including diabetes mellitus, hypertension, infiltrative processes, and obesity. Unlike in systolic heart failure, where LV ejecti...

1. Demonstrate the association between heart failure with preserved ejection fraction (HFpEF) and survival. 2. Given a patient with heart failure (HF), recognize HFpEF on the basis of clinical signs and symptoms, physical examination, echocardiography, and radiographic findings. 3. Classify patients at high risk of hospitalization and mortality through assessing risk factors, clinical presentat...
