Insights
Hypertension significantly increases cardiovascular disease risk. Antihypertensive treatments lower this risk, particularly for stroke and heart failure, but do not fully normalize it.
Area of Science:
- Cardiology
- Epidemiology
- Clinical Trials
Context:
- Hypertension is a primary risk factor for cardiovascular diseases (CVDs).
- Elevated blood pressure correlates with increased incidence of cerebral, coronary, and peripheral artery diseases.
- Epidemiological data over 30 years confirm this strong association.
Purpose:
- To review interventional trials on antihypertensive therapy in various hypertensive states.
- To discuss ongoing trials and unresolved issues in hypertension management.
- To evaluate the efficacy of blood pressure reduction on cardiovascular risk.
Summary:
- Antihypertensive treatment reduces cardiovascular risk in hypertensive patients by lowering blood pressure.
- Treatment is more effective in preventing stroke and heart failure than coronary artery disease.
- Efficacy varies across different severities of hypertension and in elderly patients with isolated systolic hypertension.
Impact:
- Provides a comprehensive review of antihypertensive therapy's effectiveness.
- Highlights the differential benefits of treatment for various cardiovascular outcomes.
- Informs future research and clinical practice for managing hypertension and its complications.
Abstract:
Several epidemiological studies carried out over the past 30 years have unequivocally shown that hypertension is a major risk factor for cardiovascular diseases, the incidence of cerebral, coronary, and peripheral artery disease being progressively higher as blood pressure values become more and more elevated. Interventional clinical trials have also shown that antihypertensive treatment is able, by decreasing high blood pressure values, to reduce the cardiovascular risk profile of the hypertensive patient, although not to normalize it. Furthermore, antihypertensive treatment has been demonstrated to be more effective in protecting against stroke and congestive heart failure than against coronary artery disease. This paper will review the results of the various interventional trials carried out in hypertensive states of different clinical severity and in isolated systolic hypertension of the elderly. It will also briefly discuss the peculiar features of the ongoing interventional clinical trials, whose results will allow clarification of important and still unsolved issues concerning antihypertensive therapy.
