BACKGROUND The optimal combination drug therapy for hypertension is not established, although current U.S. guidelines recommend inclusion of a diuretic. We hypothesized that treatment with the combination of an angiotensin-converting-enzyme (ACE) inhibitor and a dihydropyridine calcium-channel blocker would be more effective in reducing the rate of(More)
CONTEXT Hypertension is a leading cause of end-stage renal disease (ESRD) in the United States, with no known treatment to prevent progressive declines leading to ESRD. OBJECTIVE To compare the effects of 2 levels of blood pressure (BP) control and 3 antihypertensive drug classes on glomerular filtration rate (GFR) decline in hypertension. DESIGN(More)
CONTEXT Incidence of end-stage renal disease due to hypertension has increased in recent decades, but the optimal strategy for treatment of hypertension to prevent renal failure is unknown, especially among African Americans. OBJECTIVE To compare the effects of an angiotensin-converting enzyme (ACE) inhibitor (ramipril), a dihydropyridine calcium channel(More)
BACKGROUND Atherosclerotic renal-artery stenosis is a common problem in the elderly. Despite two randomized trials that did not show a benefit of renal-artery stenting with respect to kidney function, the usefulness of stenting for the prevention of major adverse renal and cardiovascular events is uncertain. METHODS We randomly assigned 947 participants(More)
Insights into end-stage renal disease have emerged from many investigations but less is known about the epidemiology of chronic renal insufficiency (CRI) and its relationship to cardiovascular disease (CVD). The Chronic Renal Insufficiency Cohort (CRIC) Study was established to examine risk factors for progression of CRI and CVD among CRI patients and(More)
Since the first International Society on Hypertension in Blacks consensus statement on the "Management of High Blood Pressure in African American" in 2003, data from additional clinical trials have become available. We reviewed hypertension and cardiovascular disease prevention and treatment guidelines, pharmacological hypertension clinical end point(More)
In the short term, the endothelin antagonist avosentan reduces proteinuria, but whether this translates to protection from progressive loss of renal function is unknown. We examined the effects of avosentan on progression of overt diabetic nephropathy in a multicenter, multinational, double-blind, placebo-controlled trial. We randomly assigned 1392(More)
Endothelial Dysfunction The endothelium constitutes the largest organ system in the body. “Endothelial function” refers to a multitude of physiological functions of the vascular endothelium that are achieved via secretion of diverse bioactive substances. This renders the endothelium an active participant in healthy homeostasis of the vascular wall that(More)
This article reports further analyses of the Hypertension Optimal Treatment (HOT) Study data with the aim to describe (1) the value of baseline serum creatinine and its clearance (estimated by Cockroft and Gault formula) as predictors of cardiovascular events, (2) the effects of intensive lowering of BP on cardiovascular events and renal function in(More)
BACKGROUND Atherosclerotic renal artery stenosis is a problem with no consensus on diagnosis or therapy. The consequences of renal ischemia are neuroendocrine activation, hypertension, and renal insufficiency that can potentially result in acceleration of atherosclerosis, further renal dysfunction, myocardial infarction, heart failure, stroke, and death.(More)
