Is Aberrant Reno-Renal Reflex Control of Blood Pressure a Contributor to Chronic Intermittent Hypoxia-Induced Hypertension?
This study demonstrated unaltered vascular conductance in response to lumbar sympathetic stimulation in CIH-exposed rats. Aortic compliance was increased and estimated blood volume was unchanged in CIH-exposed rats. Increased blood pressure was related to an increase in cardiac output, which was confirmed by echocardiography (Lucking et al., 2014). It is suggested therefore that hypertension in the CIH model can be evoked by over-excitation of the cardiac arm of sympathetic nervous system (SNS), even before mechanisms of enhanced peripheral vasoconstriction and endothelial dysfunction are initiated (Naghshin et al., 2009)....

Registration of amiloride in South Africa: Cutting the Gordian knot.
Authors: Rayner BL, Spence JD, Bryer A, Mpe MT Abstract Amiloride is an antagonist of the renal tubular epithelial sodium channel (ENaC). As such, it is a diuretic that is both potassium and magnesium sparing. It is used for the treatment of potassium depletion and hypertension, and is the specific therapy for hypertension due to overactivity of the ENaC (Liddle syndrome and several additional genetic causes of the Liddle phenotype - low renin and low aldosterone). It is listed as a World Health Organization essential drug, but has never been registered in South Africa (SA) and can therefore only be prescribed unde...

Salt Substitute Cut Disease and Death Rates in Large Trial
A randomized trial recently reported in the New England Journal of Medicine focused on an important question for older adults with high blood pressure or a previous stroke: Can switching from regular salt to a 75% sodium chloride and 25% potassium chloride substitute help protect against stroke, major cardiovascular events, or death?

Aldosterone and cardiovascular diseases
Cardiovasc Res. 2022 Apr 7:cvac027. doi: 10.1093/cvr/cvac027. Online ahead of print.ABSTRACTAldosterone's role in the kidney and its pathophysiologic actions in hypertension are well known. However, its role or that of its receptor [minieralocorticoid receptor (MR)] in other cardiovascular (CV) disease are less well described. To identify their potential roles in six CV conditions (heart failure, myocardial infarction, atrial fibrillation, stroke, atherosclerosis, and thrombosis), we assessed these associations in four areas: 1) mechanistic studies in rodents and humans; 2) preclinical studies of MR antagonists; 3) clinica...

Grading of Japanese Diet Intakes by 24-Hour Urine Analysis of Taurine and Soy Isoflavones in Relation to Cardiovascular Risks
In conclusion, the higher the J score, which corresponds to Japanese dietary habits, the lower the BMI and cholesterol levels, as well as mortality rate from coronary heart disease, but the higher the average life expectancy among the Japanese. However, these higher J scorings were associated with high-salt intake and high Na/K ratios; therefore, they contributed to high blood pressure and high mortality rate caused by stroke in Japan. These results indicate that low-salt intake should be recommended to the Japanese who are consuming seafood and soy regularly in order to maintain lower blood pressure and to extend healthy ...

Roots of < em > Astragalus propinquus < /em > Schischkin Regulate Transmembrane Iron Transport and Ferroptosis to Improve Cerebral Ischemia-Reperfusion Injury
CONCLUSION: RAP stimulation inhibited ferroptosis by regulating the expression of the key ferroptosis factors XCT, SLC3A2, GPX4, NRF2, HO-1, and IREB2. In conclusion, RAP regulates transmembrane iron transport and ferroptosis to improve CIRI.PMID:35958925 | PMC:PMC9363172 | DOI:10.1155/2022/7410865

Kids and sodium: Serious risks, alarming realities
When it comes to sodium intake among adults, the general consensus is that high consumption will increase risk of hypertension and stroke. According to the 2020 –2025 Dietary Guideline for Americans, 45% of people 18 and older are living with hypertension. Hypertension is a preventable risk factor for cardiovascular disease and stroke. Does a high sodium intake pose the same risks for children and adolescents as it does for adults? Children and adolescent s, ages 2–18, develop…

Effects of the Sodium-Glucose Cotransporter Inhibitors on Cardiovascular Death and All-Cause Mortality: A Systematic Review and Meta-analysis of Randomized Placebo-Controlled Clinical Trials
ConclusionsSodium-glucose cotransporter inhibitors  significantly reduced major adverse cardiovascular events, including hospitalization and all-cause mortality in patients with or without established atherosclerotic cardiovascular disease. We observed a beneficial trend in patients with heart failure with preserved ejection fraction, and no benefi ts in patients with stroke or myocardial infarction.

Less Sodium, More Potassium, or Both: Population-wide Strategies to Prevent Hypertension
Am J Physiol Renal Physiol. 2023 Jun 1. doi: 10.1152/ajprenal.00007.2023. Online ahead of print.ABSTRACTHypertension is among the most prevalent medical conditions globally and a major contributor to chronic kidney disease, cardiovascular disease, and death. Prevention through non-pharmacologic, population-level interventions is critically needed to halt this worldwide epidemic. However, there are ongoing debates as to where public policy efforts should focus. Recently the Salt Substitute and Stroke Study demonstrated the efficacy of substituting table salt with potassium salt to reduce the risk of stroke, major cardiovasc...
