Left ventricular morphology and function in mild to moderate essential hypertension

Area of Science:

• Cardiology
• Hypertension Research
• Echocardiography

Background:

• Essential hypertension (EH) is a prevalent cardiovascular risk factor.
• Left ventricular (LV) remodeling is a known complication of sustained hypertension.
• Early detection of LV changes is crucial for managing hypertensive heart disease.

Purpose of the Study:

• To investigate echocardiographic findings of left ventricular (LV) morphology and function in males with mild to moderate essential hypertension (EH).
• To compare LV characteristics between hypertensive patients and normotensive controls.
• To identify potential echocardiographic markers of early hypertensive cardiac changes.

Main Methods:

• Echocardiographic examination of 150 males with mild to moderate EH.
• Comparison of LV parameters (wall thickness, mass, function) with 20 normotensive men.
• Assessment of systolic and diastolic LV function indices.

Main Results:

• Significant increase in LV wall thickness (81%) and LV mass (67%) in hypertensive patients, indicative of concentric hypertrophy.
• Absence of LV hypertrophy in normotensive controls.
• Normal or slightly elevated systolic LV function, but impaired diastolic function suggested by indirect indices.
• Decreased LV end-systolic wall stress, indicating compensatory hypertrophy without dilation.
• Correlation between LV hypertrophy degree and systemic blood pressure in some patients.

Conclusions:

• Mild to moderate EH induces significant changes in LV morphology and function.
• Echocardiography is effective in detecting these early cardiac alterations.
• Concentric LV hypertrophy may be a characteristic feature of early-stage EH.
• Diastolic dysfunction is an early functional impairment in hypertensive individuals.
