Calcium antagonists for the treatment of systemic hypertension
1Hypertension Research Center, Indiana University School of Medicine, Indianapolis 46202-5111.
Insights
Diuretics effectively lower stroke risk but not atherosclerotic complications in hypertension. Metabolically neutral agents like calcium antagonists are better for treating hypertension and related cardiovascular issues.
Area of Science:
- Cardiology
- Pharmacology
- Public Health
Background:
- Diuretics reduce stroke incidence in hypertensive patients.
- Diuretics do not significantly reduce atherosclerotic complications.
- Hypertension involves multiple risk factors including diabetes and dyslipidemia.
Purpose of the Study:
- To evaluate the comprehensive effectiveness of antihypertensive agents.
- To identify optimal treatments for hypertension and associated cardiovascular risks.
- To explore the role of metabolic neutrality in cardiovascular disease management.
Main Methods:
- Analysis of large-scale clinical trial data.
- Review of pathophysiologic relationships between hypertension and other conditions.
- Comparative assessment of antihypertensive agent profiles.
Main Results:
- Diuretics show limited impact on atherosclerotic complications.
- A link exists between hypertension, left ventricular hypertrophy, diabetes, and dyslipidemia.
- Metabolically neutral agents do not adversely affect lipids or insulin sensitivity.
Conclusions:
- Calcium antagonists are suitable for treating hypertension and cardiovascular complications.
- Metabolically neutral antihypertensive agents offer advantages.
- Comprehensive management of hypertension requires addressing multiple risk factors.
Abstract:
As shown by large-scale clinical trials, the antihypertensive effectiveness of diuretics has been associated with a dramatic decrease in the incidence of stroke. This decrease, however, has not been accompanied by a similar reduction in atherosclerotic complications of hypertension, perhaps because other risk factors are important contributors to cardiovascular disease. In particular, a pathophysiologic relationship appears to exist between high blood pressure, left ventricular hypertrophy, diabetes and dyslipidemia. Thus, metabolically neutral antihypertensive agents such as calcium antagonists, which have no adverse effects on serum lipids and insulin sensitivity and can reduce left ventricular mass, are particularly suitable for the treatment of hypertension and attendant cardiovascular complications.
