Measurement of cost-effectiveness of drug therapy: a review of the treatment of hypertension

Abstract

There is good quantitative epidemiological evidence on the risk of cardiovascular disease posed by hypertension and, from large clinical trials, on the actual benefits gained from treatment of hypertension. Thus, hypertension presents a good model for the performance of cost-effectiveness analysis. From the Framingham study, it can be calculated that hypertensive men (blood pressure, greater than 160/95 mmHg) have a 2.8-fold higher cardiovascular mortality than normotensive men (blood pressure, less than 140/90 mmHg), and hypertensive women have a 2.3-fold higher incidence of cardiovascular mortality than normotensive women. Hypertension presents an equal relative risk to both men and women, but the absolute risk to men is greater. The largest absolute risk from hypertension is of coronary heart disease (144 events per 10,000 men per year); however, the largest relative risk from hypertension is of stroke (approximately 700%). From the Framingham data, it can be calculated that the complete reversal of hypertension for 18 years across a community could reduce the incidence of coronary heart disease by approximately 63%, and of strokes by 87%. Meta-analysis of the large clinical trials on the treatment of hypertension shows that...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.
