Abstract

In this review, the design and objectives of ongoing clinical trials in essential hypertension are discussed along with the main results obtained from previously published therapeutic trials. In a meta-analysis of 14 of the major primary prevention trials in hypertension, the difference in diastolic blood pressure between the intervention groups and the control groups was only 5-6 mmHg. This difference was associated with significant reductions in all stroke events (42 per cent), all coronary heart disease events (14 per cent) and in cardiovascular mortality (21 per cent). In elderly hypertensive patients, available studies have shown that antihypertensive treatment reduces the incidence of non-fatal cardiovascular events without significantly modifying cardiovascular mortality. Most of these results were obtained with beta-blockers or diuretics. Despite official recommendation as first line monotherapy, none of the three new antihypertensive classes has been shown to have beneficial effects on hard primary endpoints such as cardiovascular morbidity and mortality. Several ongoing large scale randomized controlled trials vs. beta-blockers or diuretics are addressing this important issue. Moreover, other effects of antihypertensi...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.
