Epicardial fat, left ventricular strain, and T1-relaxation times in obese individuals with a normal ejection fraction.

Epicardial fat, left ventricular strain, and T1-relaxation times in obese individuals with a normal ejection fraction. Acta Radiol. 2019 Feb 06;:284185119826549 Authors: Homsi R, Yuecel S, Schlesinger-Irsch U, Meier-Schroers M, Kuetting D, Luetkens J, Sprinkart A, Schild HH, Thomas DK Abstract BACKGROUND: Cardiac magnetic resonance (CMR) may detect early signs of cardiomyopathy. PURPOSE: The purpose of this CMR study was to evaluate epicardial fat volume (EFV), T1-relaxation times (T1), and left ventricular (LV) strain in non-obese (30 kg/m2) individuals with no other cardiovascular risk factor and with a normal LV ejection fraction (LVEF) to detect early changes of obesity cardiomyopathy. MATERIAL AND METHODS: Seventy-five individuals (38 men) without additional cardiovascular risk factors were examined at 1.5 T. EFV was assessed by a 3D-Dixon sequence. A 3(3)3(3)5 MOLLI scheme was used to assess T1 (ms). Myocardial strain (%) was evaluated by longitudinal (LS) and circumferential strain (CS) analysis. RESULTS: Obese individuals (n = 34; age = 55.6 ± 13.8 years; BMI = 33.4 ± 2.9 kg/m2) had higher EFVs (70.2 ± 27.9 vs. 56.1 ± 25.2 mL/m2; P

Abstract Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice with implications on long-term outcomes. Metabolic disorders including diabetes mellitus and obesity are independent predictors of atrial fibrillation and present therapeutic targets to reduce both the incidence and duration burden of atrial fibrillation. The presence of pericardial fat in direct contact with cardiac structures, as well the subsequent release of proinflammatory cytokines, may play an important role in this connection. Atrial fibrillation is an independent predictor of cognitive impairment and dementia....

This study demonstrates for the first time that senescent cells secrete functional LTs, significantly contributing to the LTs pool known to cause or exacerbate idiopathic pulmonary fibrosis. Against Senolytics https://www.fightaging.org/archives/2019/11/against-senolytics/ There is no consensus in science that is so strong as to have no heretics. So here we have an interview with a naysayer on the matter of senolytic treatments, who argues that the loss of senescent cells in aged tissues will cause more harm to long-term health than the damage they will do by remaining. To be clear, I think this to be a ...

ConclusionsLack of ALX/FPR2 induced obesity, reduced the lifespan, amplified leukocyte dysfunction, and facilitated profound inter-organ non-resolving inflammation. Our study shows the integrative and indispensable role of ALX/FPR2 in lipid metabolism, cardiac inflammation-resolution processes, obesogenic aging, and renal homeostasis.

Abstract Sarcopenia, obesity and their coexistence, obese sarcopenia (OBSP) as well as atherosclerosis-related cardio-vascular diseases (ACVDs), including chronic heart failure (CHF), are among the greatest public health concerns in the ageing population. A clear age-dependent increased prevalence of sarcopenia and OBSP has been registered in CHF patients, suggesting mechanistic relationships. Development of OBSP could be mediated by a crosstalk between the visceral and subcutaneous adipose tissue (AT) and the skeletal muscle under conditions of low-grade local and systemic inflammation, inflammaging. The present ...

Described herein are certain clinical and morphologic findings in 9 patients who at necropsy had hearts weighing>1000g, a weight approximately 3 times normal. With the exception of 2 patients with hypertrophic cardiomyopathy, the common finding in the remaining 7 patients was obesity. None had valvular heart disease, the previously described major cause of massive cardiomegaly. Thus, obesity needs to be added to the causes of massive cardiomegaly, a cause not previously recognized. Electrocardiograms in 4 patients disclosed high total 12-lead QRS voltage on the electrocardiogram in only one despite the massive cardiomegaly.

Adipose tissue plays a crucial role in diet- and obesity-related insulin resistance, with implications for several metabolic diseases. Identification of novel target genes and mechanisms that regulate adipocyte function could lead to improved treatment strategies. RND3 (RhoE/Rho8), a Rho-related GTP-binding protein that inhibits Rho kinase (ROCK) signaling, has been linked to diverse diseases such as apoptotic cardiomyopathy, heart failure, cancer and type 2 diabetes, in part by regulating cytoskeleton dynamics and insulin-mediated glucose uptake.

A 59-year-old woman with a history of non-ischemic cardiomyopathy (ejection fraction of 30%) and obesity was admitted to internal medicine with palpitations. She had undergone uncomplicated cardiac resynchronization therapy with defibrillator (CRT-D) placement five days previously. At a skilled nursing facility, she experienced an intermittent pulsating feeling in her left chest several times per day. She described the feeling as the sensation of “somebody doing CPR from the inside.” She was referred to the emergency department for further evaluation.
