Left ventricular diastolic dysfunction and cardiovascular regulation in hypertension
1Department of Heart and Hypertension Research, Cleveland Clinic Foundation, Ohio 44195-5069.
Insights
Hypertension can impair left ventricular diastolic function, affecting how the heart fills. Antihypertensive therapy may improve this crucial cardiac filling rate.
Area of Science:
- Cardiology
- Hypertension Research
- Physiology
Background:
- Left ventricular diastolic filling rate alterations in hypertension are not fully understood.
- Hypertension is linked to impaired peripheral vascular regulation by cardiopulmonary reflexes.
- Diastolic dysfunction in hypertension requires further investigation.
Purpose of the Study:
- To assess the determinants and physiologic consequences of altered left ventricular diastolic filling rate in hypertension.
- To review functional correlates of altered left ventricular diastolic function.
- To examine the effects of antihypertensive therapy on left ventricular filling.
Main Methods:
- Review of existing data and literature.
- Analysis of functional correlates of diastolic function.
- Evaluation of antihypertensive therapy impacts.
Main Results:
- Hypertension is associated with impaired left ventricular diastolic filling.
- Cardiopulmonary reflex dysfunction may contribute to diastolic dysfunction in hypertensive patients.
- Antihypertensive treatments may positively influence left ventricular diastolic filling rates.
Conclusions:
- Altered left ventricular diastolic filling is a significant consequence of hypertension.
- Understanding these alterations is key for managing hypertensive heart disease.
- Therapeutic interventions targeting blood pressure may improve cardiac diastolic function.
Abstract:
The determinants and physiologic consequences of altered left ventricular diastolic filling rate in hypertension has not yet been fully assessed. Data suggesting that left ventricular diastolic dysfunction in hypertension is associated with impaired peripheral vascular regulation by cardiopulmonary reflexes has been reported recently. Other functional correlates of alteration of left ventricular diastolic function are reviewed, as well as the effects of antihypertensive therapy on the rate of left ventricular filling.
