Body composition of metabolically unhealthy normal-weight patients with aortic stenosis: a prospective cohort study.

Background: The aim of this study was to evaluate the prognostic impact of computed tomography (CT)-based body composition parameters in metabolically unhealthy normal-weight patients (MUHNW) with aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR).

Methods: This prospective cohort study involved adults with normal weight scheduled for TAVR. Patients were divided into two groups: metabolically healthy normal-weight (MHNW) and MUHNW.

Prognostic utility of dynamic changes in epicardial adipose tissue in patients undergoing transcatheter aortic valve replacement.

Background: Epicardial Adipose Tissue (EAT) volume is associated with the risk of cardiovascular events, which can be assessed by cardiac computed tomography. However, he optimal method and their prognostic utility in patients following transcatheter aortic valve replacement (TAVR) is unknown.

Methods: We evaluated 258 participants, focusing on changes in EAT volume using cardiac CT enhancement.

The prognostic value of epicardial and pericoronary adipose tissue in heart failure with preserved ejection fraction using coronary computed tomography angiography.

Objectives: To assess the prognostic significance of epicardial adipose tissue volume (EATv) and pericoronary adipose tissue attenuation (PCATa) in patients with heart failure with preserved ejection fraction (HFpEF).

Methods: This retrospective study was based on HFpEF and controls who underwent coronary CT angiography (CCTA) screening to rule out coronary disease. Comparisons of EATv and PCATa were made between HFpEF patients and a control group, using statistical analyses including Kaplan-Meier and Cox regression to assess prognostic significance.
