BACKGROUND: Hypertension reduction strategies use blood pressure in the brachial artery as the primary endpoint. Individuals who achieve the target blood pressure reduction with antihypertensive treatment have residual cardiovascular risk attributed to the difference in pressure between the aorta and brachial artery. Antihypertensive treatment affects the intrinsic properties of the vascular wall and arterial stiffness markers and consequently the central pressure. Recent publications stress the importance of adequate control of the central compared to peripheral blood pressure...

We analyzed the clinical features and the factors associated with the presence of hyperkalemia (serum potassium >5.3 mmol/L) in a cohort of patients presenting to an Emergency Department. A total of 168 cases were observed (89 males and 79 females), mean age 77.512 years. Fifty-six patients were diabetics (33.3%), 51 patients had chronic kidney disease (30%) and 36 patients with cardiac failure (21.4%). Sixty-nine patients (41%) were treated with RAS-blockers (ACE-I n = 50; ARBs, n = 19). 65 subjects were taking loop diuretics (39%), 17 (10%) thiazides...

The WHO ranks hypertension the leading global risk factor for disease, specifically, cardiovascular disease. Blood pressure is higher in westernized populations consuming sodium-rich processed foods compared to isolated societies consuming potassium-rich natural foods. Evidence suggests that lowering dietary Na(+) is particularly beneficial in hypertensives who consume a high Na(+) diet. Nonetheless, numerous population studies demonstrate a relationship between higher dietary K(+), estimated from urinary excretion or dietary recall, and lower blood pressure regardless of sodium intake...

BACKGROUND: Thiazide diuretics are among the most commonly prescribed antihypertensives. However, <50% of thiazide-treated patients achieve blood pressure (BP) control. Herein, we used different omics (genomics and transcriptomics) to identify novel biomarkers of thiazide diuretics BP response. METHODS AND RESULTS: Genome-wide analysis included 228 white hypertensives with BP determined at baseline and after 9 weeks of hydrochlorothiazide. Single-nucleotide polymorphisms with P <5×10(-)(5) were prioritized according to their biological function, using RegulomeDB, haploreg, and Genome-Wide Annotation of Variants...

Diuretics have been used for years to treat hypertension as both a monotherapy and in combination. Hydrochlorothiazide, indapamide, and chlorthalidone have frequently been considered in the same category as thiazide diuretics, but there is no evidence that their activities are similar. Studies have shown that chlorthalidone and indapamide reduce cardiovascular morbidity and mortality; however, there is no study indicating that hydrochlorothiazide has beneficial effects on cardiovascular outcomes such as myocardial infarction, renal failure, stroke, or death...

BACKGROUND: Nephrotic edema is considered refractory if it does not respond to maximum or near-maximum doses of loop diuretics. This condition can be treated with loop diuretics and thiazides. However, animal studies show that the simultaneous downregulation of pendrin with acetazolamide and inhibition of the sodium-chloride cotransporter with hydrochlorothiazide generates significant diuresis, and furosemide administration following a pendrin inhibitor potentiates furosemide's diuretic effect...

Spironolactone is a well-known multi-target drug and is specifically used for the treatment of high blood pressure and heart failure. It is also used for the treatment of edema, cirrhosis of the liver, malignant, pediatric, nephrosis and primary hyperaldosteronism. Spironolactone in association with thiazide diuretics treats hypertension and in association with furosemide treats bronchopulmonary dyspepsia. The therapeutic mechanism of action of spironolactone involves binding to intracellular mineralocorticoids receptors (MRs) in kidney epithelial cells, thereby inhibiting the binding of aldosterone...

BACKGROUND: Hyponatremia is associated with increased mortality and is frequently induced by diuretic use. It is uncertain whether diuretic use is linked to mortality risk in patients with hyponatremia. STUDY QUESTION: To measure the prognostic impact of diuretic use on 30-day mortality among patients hospitalized with hyponatremia. STUDY DESIGN: Using population-based registries, we identified all patients with a serum sodium measurement <135 mmol/L within 24 hours after acute hospital admission in western Denmark from 2006 to 2012 (cumulative population of 2...

Hypokalaemia is a common clinical problem. It can lead to severe disturbances in cardiac, neurological and muscle function. We present the case of a 45-year-old woman who was transported to our hospital with cardiac arrest following ventricular fibrillation. Blood sampling revealed severe acidosis (pH 7.02) and extreme hypokalaemia (0.9 mmol/l). The low serum potassium level was most likely caused by the combination of a very deficient diet and use of a thiazide diuretic. She never reported any symptoms. An acute intracellular shift of potassium due to epinephrine and perhaps also the cathecholamines in Red Bull may have further decreased the serum potassium concentration...
