Left ventricular elastance with resting volumetric transthoracic echocardiography identifies different phenotypes in heart failure with preserved ejection fraction: A retrospective analysis of a multicenter prospective observational study.

Background: Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous entity including patients with different phenotypes of near normal, normal, and supernormal left ventricular (LV) function.

Objectives: To assess the value of resting LV elastance (also known as force) with transthoracic echocardiography (TTE) to identify HFpEF phenotypes.

Methods: In a prospective, observational, multicenter study, 2380 HFpEF patients were recruited from July 2016 to May 2024.

Clinical and Diagnostic Value of ABCDE Stress Echocardiography With Exercise in Patients With Myocardial Infarction.

Aim: Evaluation of the clinical and diagnostic role of stepwise stress echocardiography (Stress Echo) with exercise using the ABCDE protocol in patients with myocardial infarction (MI).

Material And Methods: This single-site study included 75 patients (mean age 61.6±9.

Assessment of Pulmonary Congestion According to Ultrasound and Remote Dielectric Sensing (ReDS) in Patients Hospitalized With Heart Failure.

Background: The reduction of pulmonary congestion is an essential clinical target in the management of chronic heart failure. The remote dielectric sensing (ReDS) system is a recently introduced non-invasive technology used to easily estimate the degree of lung fluid volume without any expert techniques.

Objective: To conduct a comparative assessment of pulmonary congestion according to ultrasound and ReDS technology in patients hospitalized with decompensation of chronic heart failure (CHF).

[Life expectancy for the regions of the Northwestern Federal District. Part 2: Dynamics of old age threshold.].

The paper continues the study of the population ageing in the regions of the Northwestern Federal District. It characterized population ageing based on prospective ageing indicators that take into account remaining life expectancy. The dynamics of life expectancy (LE) at birth was analyzed.
