Insights
Hypertension damages cardiac diastolic function, with left ventricular geometric patterns worsening the effects. Structural changes in the heart increase the severity of diastolic dysfunction in hypertensive patients.
Area of Science:
- Cardiology
- Cardiovascular Imaging
Background:
- Essential hypertension is a prevalent condition associated with cardiovascular complications.
- Left ventricular geometry and diastolic function are key indicators of cardiac health.
Purpose of the Study:
- To investigate the impact of different left ventricular geometric patterns on cardiac function in hypertensive patients.
- To assess the relationship between structural changes and diastolic dysfunction.
Main Methods:
- Echocardiography was employed to evaluate left ventricular geometry and diastolic function.
- 117 hypertensive patients and 45 controls were analyzed.
- Left ventricular mass index (LVMI) and relative wall thickness (RWT) were calculated to classify geometric patterns.
Main Results:
- Hypertensive patients exhibited impaired diastolic function compared to controls.
- Left atrial dimension was increased in hypertensive groups, except those with normal geometry.
- Diastolic dysfunction severity increased with the degree of left ventricular structural alteration, being most severe in concentric and eccentric hypertrophy groups.
Conclusions:
- Left ventricular geometric patterns significantly influence cardiac diastolic function in hypertension.
- Progressive cardiac structural changes correlate with increased diastolic dysfunction severity.
- Understanding these patterns is crucial for managing hypertensive heart disease.
Abstract:
To evaluate the alteration of cardiac function in hypertensive patients with different left ventricular geometric patterns. Echocardiography was used to study left ventricular geometry and cardiac diastolic function in 117 cases of essential hypertension, with 45 normal cases as controls. Echocardiographic date were used to calculated the left ventricular mass index (LVMI) and relative wall thickness (RWT), which values in turn were used to divide the subjects into four groups. The left atrial dimension of the group, with the exception of these hypertensives who showed normal geometry, was larger than that of the control group. The damage of peak of E velocity, peak of A velocity, E/A and the slope between the E and F points (E to F slope) were greater than in hypertension than in the control group. The concentric hypertrophy group and eccentric hypertrophy group suffered more serious damage of left ventricular diastolic function than the concentric remodeling group, and damage of left ventricular diastolic function in the concentric remodeling group was greater than that in the normal geometry group. The degree of cardiac diastolic function damage differed among patients with different left ventricular geometric patterns, when the cardiac structure was changed, the degree of cardiac diastolic function damage increased.
