Homocysteine is an independent risk factor for cardiovascular and cerebrovascular disease and has been proposed to contribute to vascular dysfunction. We sought to determine in a real-world clinical setting whether homocysteine levels were associated with hypertension mediated organ damage (HMOD) and could guide treatment choices in hypertension. We performed a cross-sectional analysis of prospectively collected… Continue reading #Homocysteine predicts vascular target organ damage in #hypertension and may serve as guidance for first-line antihypertensive therapy

#Zinc drives #vasorelaxation by acting in sensory nerves, endothelium and smooth muscle
Zinc, an abundant transition metal, serves as a signalling molecule in several biological systems. Zinc transporters are genetically associated with cardiovascular diseases but the function of zinc in vascular tone regulation is unknown. We found that elevating cytoplasmic zinc using ionophores relaxed rat and human isolated blood vessels and caused hyperpolarization of smooth muscle membrane.… Continue reading #Zinc drives #vasorelaxation by acting in sensory nerves, endothelium and smooth muscle
#Physical Activity as a Critical Component of First-Line Treatment for Elevated Blood #Pressure or #Cholesterol: Who, What, and How?: A Scientific Statement From the American Heart Association
Current guidelines published by the American Heart Association and the American College of Cardiology broadly recommend lifestyle approaches to prevent and treat elevated blood pressure and cholesterol. For patients with mildly or moderately elevated blood pressure and blood cholesterol, lifestyle-only approaches are the first line of therapy. The purpose of this scientific statement is to:… Continue reading #Physical Activity as a Critical Component of First-Line Treatment for Elevated Blood #Pressure or #Cholesterol: Who, What, and How?: A Scientific Statement From the American Heart Association
#Antihypertensive medication needs and blood pressure control with weight loss in the #Diabetes Remission Clinical Trial (DiRECT)
Our aim was to evaluate the safety and efficacy of a planned therapeutic withdrawal of all antihypertensive and diuretic medications, on commencing a formula low-energy diet replacement, targeting remission of type 2 diabetes. MethodsPost hoc analysis of changes in BP, antihypertensive medication prescriptions and symptoms during the initial total diet replacement phase was performed in… Continue reading #Antihypertensive medication needs and blood pressure control with weight loss in the #Diabetes Remission Clinical Trial (DiRECT)
Distinctive prognostic factor of heart #failure with preserved ejection fraction stratified with admission blood pressure
The prognostic importance of admission systolic blood pressure (SBP) in heart failure with preserved ejection fraction (HFpEF) is elusive. We aimed to clarify the pathophysiological differences between patients categorized with admission SBP among HFpEF patients. Methods and resultsWe studied 1008 inpatients from PURSUIT-HFpEF, a multicentre prospective observational registry. We classified patients as having elevated (>140… Continue reading Distinctive prognostic factor of heart #failure with preserved ejection fraction stratified with admission blood pressure
#Antihypertensives and #Statin Therapy for Primary #Stroke Prevention
The HOPE-3 trial (Heart Outcomes Prevention Evaluation–3) found that antihypertensive therapy combined with a statin reduced first stroke among people at intermediate cardiovascular risk. We report secondary analyses of stroke outcomes by stroke subtype, predictors, treatment effects in key subgroups. Methods:Using a 2-by-2 factorial design, 12 705 participants from 21 countries with vascular risk factors… Continue reading #Antihypertensives and #Statin Therapy for Primary #Stroke Prevention
Ultrasound renal #denervation for #hypertension resistant to a triple medication pill (RADIANCE-HTN TRIO): a randomised, multicentre, single-blind, sham-controlled trial
Endovascular renal denervation reduces blood pressure in patients with mild-to-moderate hypertension, but its efficacy in patients with true resistant hypertension has not been shown. We aimed to assess the efficacy and safety of endovascular ultrasound renal denervation in patients with hypertension resistant to three or more antihypertensive medications. MethodsIn a randomised, international, multicentre, single-blind, sham-controlled… Continue reading Ultrasound renal #denervation for #hypertension resistant to a triple medication pill (RADIANCE-HTN TRIO): a randomised, multicentre, single-blind, sham-controlled trial
Pharmacological blood #pressure lowering for primary and secondary prevention of cardiovascular disease across different levels of blood pressure: an individual participant-level data meta-analysis
The effects of pharmacological blood pressure lowering at normal or high-normal blood pressure ranges in people with or without pre-existing cardiovascular disease remains uncertain. We analysed individual participant data from randomised trials to investigate the effects of blood pressure lowering treatment on the risk of major cardiovascular events by baseline levels of systolic blood pressure.… Continue reading Pharmacological blood #pressure lowering for primary and secondary prevention of cardiovascular disease across different levels of blood pressure: an individual participant-level data meta-analysis
KCNQ5 Potassium Channel Activation Underlies #Vasodilation by #Tea
Tea, produced from the evergreen Camellia sinensis, has reported therapeutic properties against multiple pathologies, including hypertension. Although some studies validate the health benefits of tea, few have investigated the molecular mechanisms of action. The KCNQ5 voltage-gated potassium channel contributes to vascular smooth muscle tone and neuronal M-current regulation. Methods: We applied electrophysiology, myography, mass spectrometry… Continue reading KCNQ5 Potassium Channel Activation Underlies #Vasodilation by #Tea
