Comparative efficacy and safety of combination aliskiren/amlodipine and amlodipine monotherapy in African Americans with stage 2 hypertension.

Abstract: Initial multiple drug therapy for hypertension achieves greater and quicker reductions and higher blood pressure (BP) control rates than monotherapy. This 8-week, prospective, multicenter, randomized, double-blind study compared the efficacy and safety of the initial combination of aliskiren/amlodipine with amlodipine monotherapy in African Americans with stage 2 hypertension. After a 1- to 4-week washout, patients received aliskiren/amlodipine 150/5 mg or amlodipine 5 mg for 1 week and then were force-titrated to aliskiren/amlodipine 300/10 mg or amlodipine 10 mg for 7 weeks. At week 8, greater reductions in mean sitting systolic BP were obtained with aliskiren/amlodipine (n = 220) than with amlodipine (n = 223) (least squares mean change [standard error of the mean], -34.1 [1.14] mm Hg vs -28.9 [1.12] mm Hg; P<.001). Ambulatory and central BP measures were consistent with clinic BP findings, although these were conducted in a small subset of patients (n = 94 in ambulatory BP monitoring substudy and n = 136 for central BP). More patients achieved goal BP (<140/90 mm Hg) with aliskiren/amlodipine than with amlodipine at week 8 (57.3% vs 48.0%; P = .051). Both treatment groups had similar adverse event rates (35.0% and 32.7%, respectively). The most common adverse events were peripheral edema (7.7% with aliskiren/amlodipine and 9.0% with amlodipine), headache, fatigue, and nausea. The combination of aliskiren/amlodipine reduced peripheral, ambulatory, and central BP more than amlodipine alone with similar tolerability in African Americans with stage 2 hypertension.

Protective effects of beta blockade on pulmonary function when intracranial pressure is elevated.

Abstract: Intracranial pressure (ICP) was increased by hyperosmolar intracerebral infusion in dogs and the cardiopulmonary and catecholamine (CA) responses followed for 4 h Increased ICP evoked persistent increases in endogenous CAs, pulmonary vascular pressures, pulmonary blood volume, and venous admixture Other dogs similarly monitored were treated with a beta-blocking dose of propranolol 25 min after the onset of increased ICP Although catecholamines were increased, elevated pulmonary pressures and venous admixture returned to control levels CO and heart rate (HR) were reduced after beta blockade but systemic vascular resistance increased It was concluded that increased ICP induces sustained increases in CAs which adversely affect pulmonary pressures and shunting Selective beta blockade reverses these effects and may be useful in patients with evidence of sympathetic overactivity and progressive hypoxemia after head injury

Systolic hypertension, arterial stiffness, and vascular damage: role of the renin-angiotensin system.

Abstract: The field of hypertension is entering an exciting new era in which new concepts in basic and clinical science are being rapidly translated into new recommendations for clinical practice. It is now readily apparent that an age-related increase in stiffness of the walls of the large arteries causes the predominant hemodynamic characteristic of hypertension in later life: increased systolic blood pressure. Systolic hypertension is now recognized to have greater prognostic significance than diastolic hypertension, and it is also known that the effective treatment of systolic hypertension confers a proportional benefit in risk reduction. A rapidly advancing knowledge of vascular biology has revealed that the renin-angiotensin system plays a central role in the pathogenesis of vascular hypertrophy and arterial stiffness. Angiotensin-converting enzyme inhibitors have been shown to reduce arterial stiffness to a greater degree than diuretics or beta-blockers. The pharmacologic interruption of the renin-angiotensin system may therefore confer previously unrecognized benefits on age-related vascular damage, providing special benefits in systolic hypertension.

Cardiovascular hormonal effects of circulating norepinephrine.

Abstract: The hormonal effects of circulating norepinephrine (NE) were evaluated with two-step NE infusion studies in normal volunteers. At an infusion rate that increased plasma NE 2.5-fold (approximately equivalent to the change from supine to upright posture), there were small but consistent increases in diastolic pressure (+5 mm Hg) and plasma renin activity (+13%). At the high extreme of the physiologic range (a 9-fold increase over supine basal), circulating NE caused major changes in blood pressure (+22/15 mm Hg), heart rate (-7 bpm), and plasma renin activity (+67%). Thus, at physiologic concentrations, circulating NE should be considered to be a cardiovascular hormone as well as an index of sympathetic nervous activity.

The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure: the JNC 7 report.

Abstract: "The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure" provides a new guideline for hypertension prevention and management. The following are the key messages(1) In persons older than 50 years, systolic blood pressure (BP) of more than 140 mm Hg is a much more important cardiovascular disease (CVD) risk factor than diastolic BP; (2) The risk of CVD, beginning at 115/75 mm Hg, doubles with each increment of 20/10 mm Hg; individuals who are normotensive at 55 years of age have a 90% lifetime risk for developing hypertension; (3) Individuals with a systolic BP of 120 to 139 mm Hg or a diastolic BP of 80 to 89 mm Hg should be considered as prehypertensive and require health-promoting lifestyle modifications to prevent CVD; (4) Thiazide-type diuretics should be used in drug treatment for most patients with uncomplicated hypertension, either alone or combined with drugs from other classes. Certain high-risk conditions are compelling indications for the initial use of other antihypertensive drug classes (angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, β-blockers, calcium channel blockers); (5) Most patients with hypertension will require 2 or more antihypertensive medications to achieve goal BP (<140/90 mm Hg, or <130/80 mm Hg for patients with diabetes or chronic kidney disease); (6) If BP is more than 20/10 mm Hg above goal BP, consideration should be given to initiating therapy with 2 agents, 1 of which usually should be a thiazide-type diuretic; and (7) The most effective therapy prescribed by the most careful clinician will control hypertension only if patients are motivated. Motivation improves when patients have positive experiences with and trust in the clinician. Empathy builds trust and is a potent motivator. Finally, in presenting these guidelines, the committee recognizes that the responsible physician's judgment remains paramount.

Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure

Abstract: The National High Blood Pressure Education Program presents the complete Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. Like its predecessors, the purpose is to provide an evidence-based approach to the prevention and management of hypertension. The key messages of this report are these: in those older than age 50, systolic blood pressure (BP) of greater than 140 mm Hg is a more important cardiovascular disease (CVD) risk factor than diastolic BP; beginning at 115/75 mm Hg, CVD risk doubles for each increment of 20/10 mm Hg; those who are normotensive at 55 years of age will have a 90% lifetime risk of developing hypertension; prehypertensive individuals (systolic BP 120-139 mm Hg or diastolic BP 80-89 mm Hg) require health-promoting lifestyle modifications to prevent the progressive rise in blood pressure and CVD; for uncomplicated hypertension, thiazide diuretic should be used in drug treatment for most, either alone or combined with drugs from other classes; this report delineates specific high-risk conditions that are compelling indications for the use of other antihypertensive drug classes (angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, beta-blockers, calcium channel blockers); two or more antihypertensive medications will be required to achieve goal BP (<140/90 mm Hg, or <130/80 mm Hg) for patients with diabetes and chronic kidney disease; for patients whose BP is more than 20 mm Hg above the systolic BP goal or more than 10 mm Hg above the diastolic BP goal, initiation of therapy using two agents, one of which usually will be a thiazide diuretic, should be considered; regardless of therapy or care, hypertension will be controlled only if patients are motivated to stay on their treatment plan. Positive experiences, trust in the clinician, and empathy improve patient motivation and satisfaction. This report serves as a guide, and the committee continues to recognize that the responsible physician's judgment remains paramount.

Diagnosis and Management of the Metabolic Syndrome An American Heart Association/National Heart, Lung, and Blood Institute Scientific Statement

Abstract: The metabolic syndrome has received increased attention in the past few years. This statement from the American Heart Association (AHA) and the National Heart, Lung, and Blood Institute (NHLBI) is intended to provide up-to-date guidance for professionals on the diagnosis and management of the metabolic syndrome in adults. The metabolic syndrome is a constellation of interrelated risk factors of metabolic origin— metabolic risk factors —that appear to directly promote the development of atherosclerotic cardiovascular disease (ASCVD).1 Patients with the metabolic syndrome also are at increased risk for developing type 2 diabetes mellitus. Another set of conditions, the underlying risk factors , give rise to the metabolic risk factors. In the past few years, several expert groups have attempted to set forth simple diagnostic criteria to be used in clinical practice to identify patients who manifest the multiple components of the metabolic syndrome. These criteria have varied somewhat in specific elements, but in general they include a combination of both underlying and metabolic risk factors. The most widely recognized of the metabolic risk factors are atherogenic dyslipidemia, elevated blood pressure, and elevated plasma glucose. Individuals with these characteristics commonly manifest a prothrombotic state and a pro-inflammatory state as well. Atherogenic dyslipidemia consists of an aggregation of lipoprotein abnormalities including elevated serum triglyceride and apolipoprotein B (apoB), increased small LDL particles, and a reduced level of HDL cholesterol (HDL-C). The metabolic syndrome is often referred to as if it were a discrete entity with a single cause. Available data suggest that it truly is a syndrome, ie, a grouping of ASCVD risk factors, but one that probably has more than one cause. Regardless of cause, the syndrome identifies individuals at an elevated risk for ASCVD. The magnitude of the increased risk can vary according to which components of the syndrome are …
