BACKGROUND/AIM: Intradialytic hypotension is the most common complication associated with hemodialysis, and its cause is multifactorial. However, the relationship between hypertension and intradialytic hypotension is not clear. We investigated the influence of predialysis blood pressure and antihypertensive drugs on intradialytic hypotension. METHODS: Risk factors for intradialytic hypotension were analyzed in ...

Hypertension is a common condition with high mortality from associated diseases. Epidemiological evidence suggests that a dietary deficiency of vitamin C may be a risk factor for hypertension. However the literature on vitamin C interventional trials appears divided on the efficacy of vitamin C utilization clinically. A literature search and ...

Fish is considered protective for coronary heart disease (CHD), but mercury (Hg) intake from fish may counterbalance beneficial effects. Although neurotoxic effects of methylmercury (MeHg) are well established, cardiovascular effects are still debated. The objective of the present study was to evaluate blood pressure in relation to Hg exposure and ...

Generalized retinal arteriolar narrowing is an important sign of systemic hypertension, and a lower arteriolar:venular diameter ratio predicts the risk of hypertension. We investigated whether this association was based on arteriolar or venular diameters or both. This study was based on the prospective population-based Rotterdam Study (1990-1993) and included 1900 ...

BACKGROUND: During maintenance hemodialysis acute elevation in serum calcium is common. Low calcium dialysis is advocated as a therapy for prevention of dialysis-induced hypercalcemia. Approximately 16% of our chronic hemodialysis patients experience elevated arterial blood pressure during the hemodialysis session, becoming hypertensive by the end of the treatment. All these ...

Patients with resistant hypertension present high prevalence of a non-dipper blood pressure pattern. Recent results indicate that non-dipping is related partly to the absence of 24-hour therapeutic coverage in patients treated with single morning doses. Accordingly, we investigated the impact of treatment time on the blood pressure pattern in 700 ...

Aspirin is a potent antioxidative agent that reduces vascular production of superoxide, prevents angiotensin II-induced hypertension, and induces NO release. Low-dose aspirin administered at bedtime, but not on awakening, has also been shown to reduce blood pressure, possibly enhancing the nocturnal trough in NO production. Because endothelium-dependent vasodilation is blunted ...

Hypertension is a common disorder with well-recognized consequences on the heart, brain, and kidney as target organs. Guidelines espouse a treatment goal of blood pressure reduction to <140 mm Hg for the systolic pressure and <90 mm Hg for the diastolic pressure in most hypertensive patients. In this review, the ...

BACKGROUND: Impaired neural control of heart rate, elevated arterial stiffness, and hypertension place patients with end-stage renal disease (ESRD) at increased risk of cardiovascular mortality. Nocturnal hemodialysis (6 x 8 hours/week), a more intense program than conventional hemodialysis (3 x 4 hours/week), lowers blood pressure and restores brachial dilator responses ...

BACKGROUND: Many cases of end-stage renal disease (ESRD) are ascribed to hypertension. However, because renal disease itself can raise blood pressure, some investigators argue that ESRD seen in patients with hypertension is due to underlying primary renal disease. Previous cohort studies of the relationship between blood pressure and ESRD did ...
