The goal of antihypertensive therapy is to abolish the risks associated with blood pressure (BP) elevation without adversely affecting quality of life. Drug selection is based on efficacy in lowering BP and in reducing cardiovascular (CV) end points including stroke, myocardial infarction, and heart failure. Although the choice of initial drug therapy(More)
To investigate the pathophysiology of nonpharmacologically induced panic attacks, 18 drug-free agoraphobic patients and 13 matched healthy subjects underwent structured exposure to phobic situations. Heart rate, blood pressure, and plasma free 3-methoxy-4-hydroxyphenylglycol (MHPG), cortisol, growth hormone, and prolactin levels were measured before,(More)
The relation between baseline clinical variables and subsequent mortality was examined in 295 patients with mild to moderate heart failure who participated in a multicenter trial comparing the effect on treadmill exercise tolerance of captopril, digoxin and placebo given in addition to a diuretic drug. At baseline study, all patients had a left ventricular(More)
Aliskiren is a potent, highly specific renin inhibitor with better oral bioavailability than earlier renin inhibitors and a long plasma half-life that makes it suitable for once-daily dosing. The efficacy and safety of aliskiren in treating hypertension has been studied in clinical trials both as monotherapy, comparing it with existing antihypertensive(More)
BACKGROUND African Americans with hypertension, particularly those with more severe blood pressure elevations, are generally less responsive to monotherapy from any antihypertensive class. These patients usually require treatment with drugs from > or = 2 antihypertensive classes to achieve adequate blood pressure control. OBJECTIVE The purpose of this(More)
BACKGROUND Stopping the detrimental effects of the renin-angiotensin system at the most upstream point of the cascade offers theoretical advantages for cardiovascular protection. This study compares the antihypertensive efficacy and safety of the novel oral renin inhibitor aliskiren with placebo and an active comparator. METHODS AND RESULTS The study was(More)
The purpose of this multicenter investigation was to determine the efficacy and safety of the alpha/beta-blocker labetalol versus the beta 1-selective beta-blocker atenolol in white and black patients with essential hypertension. Equal numbers of black and white patients were enlisted to form four treatment groups (white patients taking either labetalol or(More)
BACKGROUND AND PURPOSE The physiological basis for the arrhythmias commonly observed after a stroke is not well understood. Based on evidence that the right and left cerebral hemispheres influence cardiac function in different ways, we sought to determine whether the nature and severity of cardiac arrhythmias in the context of an acute stroke vary in(More)
BACKGROUND The fixed-dose combination of any two antihypertensive drugs from different drug classes is typically more effective in reducing blood pressure than a dose increase of component monotherapy. We assessed the efficacy and safety of a fixed-dose combination of a vasodilating β blocker (nebivolol) and an angiotensin II receptor blocker (valsartan) in(More)
BACKGROUND The mechanism by which angiotensin-converting enzyme inhibitors reduce mortality rates and disease progression in patients with heart failure is likely mediated in part through prevention of adverse ventricular remodeling. This study examined the effects of the angiotensin-converting enzyme inhibitor captopril and the angiotensin II type 1(More)
