Android to gynoid fat ratio and its association with functional capacity in male patients with heart failure

AbstractAimsWe studied the association between android (A) to gynoid (G) fat ratio and functional capacity (peak VO2) in male patients with heart failure with reduced ejection fraction (HFrEF).Methods and resultsWe enrolled 118 male patients with HFrEF with left ventricular ejection fraction (LVEF) 25 kg/m2 with FNIH index 0.55 was detected in 60 patients. Relative peak VO2 was lower in patients with A/G ratio> 0.55 than in patients with A/G ratio

A fair amount of effort is presently put towards the exploration of supplements derived from vitamin B3 compounds (nicotinamide, niacin, nicotinamide riboside) that act as precursors to enable the manufacture of nicotinamide adenine dinucleotide (NAD). NAD is an important component in mitochondrial activity, and levels decline with age. Some portion of the loss of mitochondrial function, implicated in the progression of many age-related conditions, is due to NAD insufficiency. There is a rich history of the use of high doses of vitamin B3 as an intervention, most of it predating modern understanding of the role of NAD in m...

Chronological aging as well as biological aging accelerated by various pathologies such as diabetes and obesity contribute to cardiovascular aging, and structural and functional tissue damage of the heart and vasculature. Cardiovascular aging in humans is characterized by structural pathologic remodeling including cardiac and vascular fibrosis, hypertrophy, stiffness, micro- and macro-circulatory impairment, left ventricular diastolic dysfunction precipitating heart failure with either reduced or preserved ejection fraction, and cardiovascular cell death. Cellular senescence, an important hallmark of aging, is a critical f...

AbstractThe heart failure (HF) epidemic is growing and approximately half of the HF patients have heart failure with preserved ejection fraction (HFpEF). HFpEF is a heterogeneous syndrome, characterized by a preserved left ventricular ejection fraction (LVEF ≥ 50%) with diastolic dysfunction, and is associated with high morbidity and mortality. Underlying comorbidities of HFpEF, i.e., hypertension, type 2 diabetes mellitus, obesity, and renal failure, lead to a systemic pro-inflammatory state, thereby affecting normal cardiac function. Increased inf lammatory biomarkers predict incident HFpEF and are higher in pa...

In this study, we analyzed whether the risk of HF increases in participants according to baseline glycemic status and whether this increased risk is associated with obesity status. METHODS: We analyzed the risk of HF according to baseline glycemic status (normoglycemia, impaired fasting glucose [IFG], and diabetes) in 9,720,220 Koreans who underwent Korean National Health Screening in 2009 without HF at baseline with a median follow-up period of 6.3 years. The participants were divided into five and six groups according to baseline body mass index (BMI) and waist circumference, respectively. RESULTS: Participants w...

In cardiomyocytes, there is microRNA (miR) in the mitochondria that originates from the nuclear genome and matures in the cytoplasm before translocating into the mitochondria. Overexpression of one such miR, miR-181c, can lead to heart failure by stimulating reactive oxygen species (ROS) production and increasing mitochondrial calcium level ([Ca2+]m). Mitochondrial calcium uptake 1 protein (MICU1), a regulatory protein in the mitochondrial calcium uniporter complex, plays an important role in regulating [Ca2+]m.

This study provides direct evidence for the contribution of gut microbiota to the cognitive decline during normal aging and suggests that restoring microbiota homeostasis in the elderly may improve cognitive function. On Nutraceutical Senolytics https://www.fightaging.org/archives/2020/05/on-nutraceutical-senolytics/ Nutraceuticals are compounds derived from foods, usually plants. In principle one can find useful therapies in the natural world, taking the approach of identifying interesting molecules and refining them to a greater potency than naturally occurs in order to produce a usefully large therape...
