[Changes in the intracardiac hemodynamics of patients with essential hypertension during korinfar treatment]
Insights
Corinfar monotherapy effectively treats essential hypertension by dilating blood vessels, primarily affecting preload. This leads to changes in the heart's pumping action, specifically altering left ventricular systole towards reduced myocardial contractility.
Area of Science:
- Cardiology
- Pharmacology
- Hypertension Research
Background:
- Essential hypertension is a common cardiovascular condition.
- Understanding the cardiac effects of antihypertensive medications is crucial for patient management.
- Corinfar (nicardipine) is used to treat hypertension.
Purpose of the Study:
- To investigate the effects of corinfar monotherapy on cardiac structure and function during diastole.
- To analyze intracardiac hemodynamics and left ventricular systole in patients with essential hypertension treated with corinfar.
Main Methods:
- Study included 39 patients with moderate essential hypertension.
- Corinfar monotherapy was administered.
- Cardiac structure and function, including diastole and left ventricular systole, were assessed.
Main Results:
- Effective corinfar monotherapy demonstrated arteriolar and venodilating effects.
- The drug's primary effect was on preload reduction.
- Intracardiac hemodynamic changes led to alterations in left ventricular systole, shifting towards myocardial hypodynamia.
Conclusions:
- Corinfar monotherapy effectively manages essential hypertension through vasodilation and preload reduction.
- The observed changes in left ventricular systole indicate a potential impact on myocardial contractility, warranting further investigation.
Abstract:
A study is presented of the structure and function of the heart in the diastole in 39 patients during corinfar treatment of essential hypertension. It was established that effective corinfar monotherapy of patients with moderate essential hypertension was associated with arteriolo- and venodilating effect of the drug with prevalence of the preloading effect. Changes of the intracardiac hemodynamics resulted in changes of the left ventricular systole phase structure, namely, its transformation in the direction of myocardial hypodynamia.
