[Morphologic and functional aspects of left ventricular hypertrophy evaluated by computerized echocardiography]

Area of Science:

• Cardiology
• Medical Imaging
• Hypertension Research

Context:

• Left ventricular (LV) hypertrophy is a common adaptation to hypertension.
• Understanding the progression and differentiation of LV hypertrophy is crucial for patient management.
• Echocardiography offers valuable morphological and functional insights into cardiac changes.

Purpose:

• To investigate the echocardiographic progression of LV hypertrophy in various stages of primary hypertension.
• To compare morphofunctional characteristics of LV hypertrophy in primary hypertension, renovascular hypertension, hypertrophic obstructive cardiomyopathy, and physical training.
• To differentiate LV hypertrophy secondary to primary hypertension from that secondary to renovascular hypertension.

Summary:

• Progressive increases in LV mass and septal hypertrophy (IVST/PWT) were observed with increasing hypertension duration and severity.
• Diastolic function, particularly isovolumic relaxation period (IRP) and filling velocities, showed distinct alterations across hypertensive groups.
• Renovascular hypertension exhibited greater LV mass increase, concentric hypertrophy, and prolonged IRP compared to long-standing primary hypertension.

Impact:

• Echocardiographic parameters can track LV hypertrophy progression in hypertension.
• Morphofunctional differences aid in distinguishing hypertensive heart disease subtypes.
• This study provides a basis for targeted therapeutic strategies in hypertensive heart disease.
