Beta-adrenergic antagonists in hypertension: a review of the evidence
Abstract
To evaluate the effects of beta-adrenergic antagonist therapy on cardiovascular and cerebrovascular outcomes in the treatment of hypertension. Literature searches were conducted using MEDLINE (1966-August 2009), International Pharmaceutical Abstracts (1970-August 2009), and Cochrane Database of Systematic Reviews (until third quarter 2009) to locate clinical trials and meta-analyses comparing beta-blocker therapy with placebo or other antihypertensive agents in patients with hypertension. Bibliographies from relevant research and review articles were reviewed for additional references. All English-language articles identified from the data sources were reviewed. Articles describing original research with cardiovascular or cerebrovascular outcomes and/or death as either primary or secondary endpoints were included. Articles describing the use of beta-blocker therapy for conditions other than hypertension were not included. Five placebo-controlled studies and 10 active-controlled studies were reviewed. In addition, 11 meta-analyses were evaluated. Placebo-controlled trials of beta-blockers in hypertension provide evidence of reduced risk for stroke, cardiovascular events, and heart failure. Only 2 studies comparing beta-blockers ...Continue Reading

Cardiovascular Disease Pathophysiology
Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
Antihypertensive Agents: Mechanisms of Action
Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
