Obesity and hypertension are associated with a variety of diseases and increased cardiovascular morbidity and mortality. The left ventricular hypertrophy (LVH) has also been shown to be an independent risk factor for cardiovascular morbidity and mortality. The combination of hypertension and obesity are well known to act as risk factors for LVH in a number of studies, but it is unclear whether obesity in itself stimulates LVH independently. The purpose of this study is to examine any relationship that exists between left ventricular diastolic function parameters, obesity, and LVH in patients that suffer from hypertension. Understanding this relationship is important as LVH can be interpreted as an early sign of hypertensive heart disease. I evaluated the effect of left ventricular diastolic dysfunction and hypertension on LVH with regards to obesity, and I found that obesity and LVH in hypertensive patients are closely associated with left ventricular diastolic dysfunction.
