Abstract Aims. Blood pressure control is influenced by various genetic and environmental factors, and genetic susceptibility is important in the development of essential hypertension. Because the renin-angiotensin-aldosterone system (RAAS) has a key role in vasoconstriction, vasodilation, and sodium and electrolyte balance, it is central in blood pressure control and so ...

BACKGROUND: Continuous positive airway pressure (CPAP) is an effective therapy for obstructive sleep apnea (OSA). However, for patients who already have OSA and coronary heart diseases (CHD) with optimal medications, whether CPAP can reduce the blood pressure (BP) is not clear. This is a controlled study to evaluate the effects ...

Aims Major guidelines recommend lowering systolic blood pressure (SBP) to <140 mmHg in all hypertensives, but evidence is missing whether this is beneficial in (i) uncomplicated hypertensives, (ii) grade 1 hypertensives, and (iii) elderly hypertensives. Providing this missing evidence is important to justify efforts and costs of aggressive therapy in ...

Obstructive sleep apnoea (OSA) plays a significant role in increasing blood pressure. Significant decreases were reported in blood pressure of hypertensive OSA patients with sleepiness who underwent continuous positive airway pressure (CPAP) treatment, but not in non-sleepy hypertensive OSA patients. More recently, however, significant decreases in blood pressure in non-sleepy ...

Flow-mediated dilatation (FMD) is widely used as an index of nitric oxide-mediated vasodilator function, yet its methodology has not been well established. Previous research indicates that a rapid inflation of a blood pressure cuff evokes systemic vasoconstriction, as it was observed even on non-occluded contralateral arm. This would potentially contribute ...
