Left Ventricular Hypertrophy

In one study, 70.7% of obese patients had left ventricular remodeling before weight loss; after weight loss, 58.8% exhibited normal left ventricular geometry. The prevalence of left ventricular hypertrophy ranges from 36% to 41%, depending on diagnostic criteria, making it a common structural condition rather than a rare outcome. Unlike skeletal muscle strengthened by training, a heart thickened by chronic metabolic and pressure stress becomes stiffer and may lose its ability to relax or pump effectively. Multiple mechanisms converge on the left ventricle including elevated blood pressure, elevated insulin, TNF-alpha, IL-6, and direct inflammatory exposure from epicardial fat. Obesity causes a two-fold increased risk of developing left ventricular hypertrophy.
