Left ventricular mass in diabetes-hypertension

Area of Science:

• Cardiology
• Endocrinology
• Hypertension Research

Background:

• Essential hypertension is a significant risk factor for cardiovascular disease.
• Diabetes mellitus (DM) is increasingly prevalent and associated with adverse cardiovascular outcomes.
• The specific impact of DM on cardiac remodeling in hypertensive individuals requires further elucidation.

Purpose of the Study:

• To determine if diabetes mellitus (DM) accelerates the development of left ventricular hypertrophy (LVH) in patients with essential hypertension.
• To investigate the relationship between DM, hypertension, and cardiac structural changes.

Main Methods:

• Two-dimensional M-mode echocardiography was used to assess cardiac structure, systolic function, and hemodynamics.
• Diabetic and nondiabetic patients with essential hypertension were compared.
• Key echocardiographic parameters including interventricular septum thickness, posterior wall thickness, and left ventricular mass index were analyzed.

Main Results:

• Diabetic hypertensive patients exhibited significantly greater interventricular septum and posterior wall thickness compared to nondiabetic hypertensive patients.
• Left ventricular mass index was substantially higher in diabetic hypertensive patients (158 +/- 45 g/m2) versus nondiabetic hypertensive patients (113 +/- 20 g/m2).
• A higher prevalence of LVH was observed in diabetic patients (72%) compared to nondiabetic patients (32%) based on Devereux criteria.

Conclusions:

• Diabetes mellitus accelerates the development of left ventricular hypertrophy in essential hypertensive patients, irrespective of arterial pressure.
• This accelerated LVH in diabetic hypertensive patients may contribute to increased cardiovascular morbidity and mortality.
• DM represents an independent risk factor for cardiac remodeling in the context of hypertension.
