Background: There is a paucity of information on the effectiveness of angiotensin II-receptor antagonists in lowering blood pressure (BP) in black African hypertensive patients. This study was conducted to evaluate the antihypertensive effect, tolerability and safety profile of telmisartan, an angiotensin II-receptor antagonist, when given alone or as add- on ...

Some beta-blockers are less effective in reducing central blood pressure than other antihypertensive drugs, which may explain the higher rate of events in subjects randomized to atenolol in recent trials. We hypothesized that nebivolol, a mixed beta-blocker/nitro-vasodilator, would be more effective than atenolol in reducing central blood pressure and augmentation ...

INTRODUCTION: The introduction of phosphodiesterase-5 inhibitors as sildenafil, tadalafil, or vardenafil, has tremendously improved the treatment of erectile dysfunction. Patients with the common comorbidity of cardiovascular disease and erectile dysfunction, however, are at risk for critical hypotension in case of self-treatment of cardiac angina with nitrates after the intake of ...

Angiotensin II type-1 receptor blockers (ARBs) are regarded as first-line treatments for type-2 diabetes with hypertension. Despite the availability of various types of ARBs, there are no comparative studies of their effects on patients with diabetes. In this open-label prospective crossover study, we compared the effects of olmesartan (20 mg/day) ...

By pre-synaptic stimulation of DA(2)-dopaminergic and alpha(2)-adrenergic receptors, nolomirole inhibits norepinephrine secretion from sympathetic nerve endings. We performed a clinical study with nolomirole in patients with heart failure (HF). The study was designed as a multicentre, double blind, parallel group trial of 5 mg b.i.d. of nolomirole (n=501) versus placebo ...

Guidelines stress the importance of the simultaneous management of multiple cardiovascular risk factors. This can in part be achieved by coadministration of lipid-lowering and antihypertensive treatments. Potential pharmacodynamic interaction between drugs should be investigated as part of developing single-pill combinations. The Respond trial assessed whether combining amlodipine to treat hypertension ...

BACKGROUND: Angiotensin II-mediated increases in sympathetic activity may contribute to smaller blood-pressure decreases in response to dihydropyridines in young versus older hypertensive patients. We evaluated whether quinapril unmasks angiotensin II-dependent sympathetic activity on amlodipine. METHODS: In this double-blind, randomized, clinical trial, young mild hypertensives were randomized to quinapril for 1 ...

Both strict blood pressure control and efferent artery dilatation are critical in reducing proteinuria, which in turn helps to regulate blood pressure. Benidipine, an L- and T-type calcium channel blocker, has the potential for increased effectiveness compared with L-type-dominant calcium channel blockers such as amlodipine. Therefore, we evaluated blood pressure ...

Valsartan administration at bedtime as opposed to on wakening improves the sleep time-relative blood pressure decline toward a more dipper pattern without loss in 24-hour efficacy. Yet to be determined is whether this administration time-dependent efficacy is a class-related feature, characteristic of all angiotensin receptor blockers or specific only to ...

The intake of (n-3) long-chain PUFA is associated with a decreased risk of fatal myocardial infarction. Whether this effect is attributable to the effects of docosahexaenoic acid [22:6(n-3) (DHA)] on vascular function, particularly at intakes <1 g/d, is unknown. We report a randomized, double-blind, crossover, placebo controlled trial of 0.7 ...

S-amlodipine is the only vaso-active enantiomer of amlodipine. This article reviews the published data in nearly 5000 patients. Randomised controlled trials of S-amlodipine at half the dose of racemate in the treatment of hypertension, have shown it to be as effective as racemic amlodipine. The postmarketing surveillance studies (n = ...

Current guidelines from the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure recommend first-line treatment with a thiazide diuretic but do not provide specific guidance for obese patients. The renin system is activated in obesity-associated arterial hypertension. Therefore, we tested the hypothesis that the oral ...

BACKGROUND: Only a minority of hypertensive individuals is adequately controlled for their hypertension, partially because reliable predictors for efficient antihypertensive drug therapy are lacking. METHODS: In a prospective, randomized, double-blind, cross-over, placebo-controlled study (The GENRES Study), 208 moderately hypertensive Finnish men (aged 35 to 60 years) were treated for 4 ...

BACKGROUND: Most hypertensive renal transplant recipients require two or more antihypertensive medications to achieve blood pressure control. However, which medications must be combined is still a matter of debate. METHODS: A prospective randomized open-label blinded evaluation trial comparing the six-month effects of the amlodipine-enalapril combination (n = 32) vs. enalapril ...

BACKGROUND: Coenzyme Q10 (CoQ10) is an endogenous cofactor required for mitochondrial energy production and touted to treat heart failure and prevent statin-induced myopathy. In guinea pig ventricular myocytes, CoQ10 prolongs action potential duration, an effect that might prolong the QTc interval in humans. Additionally, CoQ10 reduced blood pressure in patients ...

OBJECTIVE: Although alpha-blockers are effective in lowering blood pressure, they may increase heart rate, an unwanted effect that could negatively affect outcome. However, the alpha-blocker urapidil might not increase heart rate due to its additional effect on 5-HT1A receptors. Therefore, we compared the effects of urapidil on heart rate with ...
