The blood pressure J-curve discussion has been ongoing for more than 30 years, yet there are still questions in need of definitive answers. On one hand, existing antihypertensive therapy studies provide strong evidence for J-curve-shaped relationships between both diastolic and systolic blood pressure and primary outcomes in the general hypertensive patient ...

Dietary salt consumption is closely associated with the level of blood pressure (BP); stricter salt reduction more markedly decreased BP. Obesity/metabolic syndrome, Dietary Approach to Stop Hypertension (DASH) diet, exercise and mental stress influence the BP-elevating effect of high-salt diet. Observational and intervention studies suggested that salt restriction improved the ...

Hypertension treatment and control efforts represent a major component of primary care with dedicated clinical guidelines and recommendations. However, high blood pressure (BP) control rates are complicated with the difficult to treat and resistant hypertensive patients. This category of patient, therefore, affects the development and implementation of the clinical guidelines. ...

Pre-hypertension, defined as blood pressure 120-139/80-89 mmHg, affects ~70 million people in the US. Blood pressures in the upper half of the pre-hypertensive range are linked with roughly threefold greater risk of incident hypertension than normal blood pressure <120/<80 mmHg, with an incidence rate of 8-20 % annually. Blood pressures in the upper ...

Obstructive sleep apnea (OSA) is a risk factor for the development of hypertension and cardiovascular disease. Apnea overloads the autonomic cardiovascular control system and may influence blood pressure variability, a risk for vascular damage independent of blood pressure levels. This study investigates the hypothesis that blood pressure variability is associated ...

Guidelines on home blood pressure measurement (HBPM) recommend taking at least 12 measurements. For screening purposes, however, it is preferred to reduce this number. We therefore derived and validated cut-off values to determine hypertension status after the first duplicate reading of a HBPM series in a web-based worksite health promotion ...

The increased risk of cardiovascular morbidity and mortality associated with arterial hypertension is particularly pronounced in patients with type 2 diabetes mellitus. Blood pressure control is, therefore, decisively important but often not sufficiently achieved. The primary objective of this study was to evaluate the antihypertensive effect of low dose spironolactone ...

Hypertension affects about 40% of the world's population and is a major risk factor for cardiovascular events. The important role of salt balance and aldosterone regulation in hypertension and cardiovascular disease has become increasingly evident over recent decades. Several recent studies have now shed some light on hyperaldosteronism and the ...

Essential hypertension is associated with multiple metabolic abnormalities, among them one of the most important is hyperinsulinemia. Hyperinsulinemia has been suggested as being responsible for the increased arterial pressure in patients with essential hypertension. But this is contradicted by the finding that all patients of essential hypertension are not hyperinsulinemic. ...

Our aim is to study associations between circulating endostatin, hypertension duration, and hypertensive target-organ damage. Long-term hypertension induces cardiovascular and renal remodeling. Circulating endostatin, a biologically active derivate of collagen XVIII, has been suggested to be a relevant marker for extracellular matrix turnover and remodeling in various diseases. However, the ...
