It has been suggested that nitrate-rich beetroot juice (BRJ) reduces blood pressure (BP) in various populations. We aimed to investigate the effect of BRJ on BP in adults with hypertension according to the European Society of Hypertension Guidelines (clinical BP ≥ 140/≥ 90 mmHg) and whether BRJ can be considered as an adjunct to hypertension drug treatment, by conducting a meta-analysis of randomized controlled trials. PubMed, SCOPUS, Medline Ovid, Cinahl, Cochrane Library and Web of Science were searched from inception until April 13, 2024 to identify randomized controlled trials of BRJ versus placebo, water, or no intake. Risk of bias was assessed using a standardized appraisal instrument from the Swedish Agency for Health Technology and Assessment of Social Services, which is based on the Cochrane risk-of-bias tool for randomized trials. The pooled BP effect size was calculated using random effects models and meta-regression. Certainty of evidence was a

Nutraceuticals in Patients With Heart Failure: A Systematic Review.

Nutraceuticals are pharmacologically active substances extracted from vegetable or animal food and administered to produce health benefits. We recently reviewed the current evidence for nutraceuticals in patients diagnosed with heart failure as part of the writing of the Australian Guidelines for the prevention, diagnosis, and management of heart failure. A systematic search for studies that compared nutraceuticals to standard care in adult patients with heart failure was performed. Studies were included if >50 patients were enrolled, with ≥6 months follow-up. If no studies met criteria then studies <50 patients and <6 months follow-up were included. The primary outcomes included mortality/survival, hospitalization, quality of life, and/or exercise tolerance. Iron was not included in this review as its role in heart failure is already well established. Forty studies met the inclusion criteria. The strongest evidence came from studies of polyunsaturated fatty acids, wh

Nitrate-rich Beet Juice Intake and Aerobic Exercise on Cardiovascular Health of Postmenopausal Women With Arterial Hypertension

n=20 · NCT05384340 · UNKNOWN · UNKNOWN

In the context of physical exercise, there is no evidence of the acute and continued use of beetroot juice with a previously recommended dose of nitrate (NO3) (\>300mg) on the cardiovascular performance of hypertensive and postmenopausal women. We will investigate the effects of beetroot juice rich in NO3 acutely (first day: 140mL/800mg) and during a week with daily doses (second to the seventh day: 70mL/400mg) on blood pressure, heart rate (HR), cardiac autonomic control, EF, inflammatory, hormonal, and stress biomarkers oxidative stress and enzymes involved in nitric oxide synthesis and mitochondrial regulation, under resting conditions, as well as mediated by submaximal aerobic exercise sessions. Through a randomized, crossover, triple-blind, placebo-controlled clinical trial, 20 physically inactive hypertensive women will undergo an acute and 7-day trial, each with two intervention protocols: 1) placebo and 2) beetroot; in which will ingest beet juice with or without NO3 in its composition with a 7-day washout interval. On collection days, exercise will be performed on a treadmill for 40 minutes at a speed corresponding to 65-70% of VO2peak. The collection of variables (cardiovascular, autonomic, and blood samples for molecular analyses) of the study will take place at rest (120 minutes after ingestion of the intervention), during exercise (40 minutes), and in the effort recovery stage (during 65 minutes) based on previously validated protocols. The collections were arranged so that the measurement of one variable does not interfere with the other and that they have adequate intervals between them.
