Effects of reducing sedentary behaviour on heart rate variability and cardio‐metabolic biomarkers in desk workers with untreated high blood pressure

Experimental Physiology, EarlyView.
Abstract Lower sedentary behaviour (SB) has been associated with reduced cardiovascular disease and mortality. Yet, few trials have evaluated cardiovascular mechanisms of benefit. We examined the effects of a SB reduction intervention on heart rate variability (HRV) and cardio‐metabolic biomarkers.

Acute hot‐water immersion augments the diastolic blood pressure nocturnal dip in healthy adults

Experimental Physiology, EarlyView.
Abstract Hot‐water immersion (HWI) has been shown to reduce 24 h ambulatory systolic blood pressure in hypertensive adults and might represent a preventative strategy for maintaining cardiovascular health in normotensive adults. The purpose of this study was to determine the time course of post‐HWI hypotension and test the hypothesis that a single HWI ...

Renin Angiotensin Aldosterone System Blockers

Renin Angiotensin Aldosterone System Blockers
The renin angiotensin aldosterone (RAA) system plays a central role in regulating cardiovascular and renal functions and is a key component of the blood pressure homeostasis system. Renal hypoperfusion triggers the production and release of renin from the juxtaglomerular cells, converting angiotensinogen to the decapeptide angiotensin I (angiotensin [1-

Cardiac remodelling in type 2 diabetes: Pathophysiological mechanisms and opportunities for multiscale computational modelling and simulation

The Journal of Physiology, EarlyView.
Abstract figure legend Overview of multiscale cardiac remodelling in type 2 diabetes and how to model and simulate these changes using a human‐based, multiscale computational framework. Cardiac remodelling in type 2 diabetes occurs at ionic channel, protein, cellular, tissue and whole‐organ level, affecting the electrophysiological function, mechanical

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

The Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

Idiopathic orthostatic hypotension: Recent data (eleven cases) and review of the literature [PDF]

Eight cases of Shy-Drager syndrome and three of Bradbury-Eggleston idiopathic orthostatic hypotension were examined. In all cases, examination of circulatory reflexes showed major dysfunction of the sympathetic vasoconstrictor system.
