Objectives of high blood pressure treatment: left ventricular hypertrophy, diastolic function, and coronary reserve
1Department of Medicine, University of Düsseldorf, Germany.
Insights
Early hypertensive heart disease shows structural and functional changes. Long-term drug treatment can reverse left ventricular hypertrophy and improve heart function.
Area of Science:
- Cardiology
- Hypertension Research
- Pharmacology
Background:
- Hypertensive heart disease involves early morphologic changes like interstitial fibrosis and arteriolar wall thickening.
- Functional alterations include diastolic dysfunction and reduced coronary reserve.
- These represent the earliest clinically detectable cardiac end-organ lesions.
Purpose of the Study:
- To investigate the effects of long-term pharmacotherapy on the prehypertrophic state of hypertensive heart disease.
- To assess the impact of beta-blockers, calcium channel blockers, and ACE inhibitors on cardiac structure and function.
Main Methods:
- Analysis of morphologic and functional alterations in the prehypertrophic state.
- Evaluation of long-term (9-12 months) pharmacotherapy with specific drug classes.
Main Results:
- Long-term pharmacotherapy with beta-blockers, calcium channel blockers, or ACE inhibitors reversed left ventricular hypertrophy by 8% to 14%.
- Significant improvements in coronary reserve and diastolic dysfunction were observed.
- ACE inhibitors and calcium channel blockers were particularly effective in improving coronary reserve and diastolic function.
Conclusions:
- Early detection and treatment of hypertensive heart disease are crucial.
- Pharmacological interventions can effectively reverse cardiac remodeling and improve diastolic function.
- ACE inhibitors show promise as a preferred treatment for improving coronary reserve and diastolic dysfunction in hypertensive heart disease.
Abstract:
The prehypertrophic state of hypertensive heart disease is characterized by morphologic changes (interstitial fibrosis, increase in intramyocardial arteriolar wall thickness) as well as by functional alterations (diastolic dysfunction, decrease in coronary reserve). These changes most probably represent the earliest cardiac end-organ lesions that can clinically be detected. In cardiac hypertrophy, long-term (9-12 months) pharmacotherapy with beta-blockers, calcium channel blockers, or ACE inhibitors reverses left ventricular hypertrophy by 8% to 14%, whereas marked improvement in coronary reserve and diastolic dysfunction is achieved by calcium blocker and preferably by ACE inhibitors.
