Abstract
Cardiovascular diseases are a major public health concern, especially in high-risk patients such as obese and diabetic populations. Subclinical changes in left ventricular (LV) structure and function have been described in obese subjects without overt heart disease.
Obesity is a complex health issue to address; it is a disorder involving an excessive amount of body fat. Obesity isn’t just a cosmetic concern. Being extremely obese means you are likely to have health problems related to your weight. It increases the risk of diseases and health problems, such as heart disease, type 2 diabetes mellitus, hypertension and premature death.
Obesity is a serious concern , It affects one third of adults. It is associated with the leading causes of death in the U.S. and worldwide, including diabetes mellitus and heart disease. Increased body mass index (BMI) has been reported in 11% and 14% of heart failure cases in men and women, respectively, stroke, and some types of cancer (i.e. Cancer liver, kidney, breast, endometrial, prostate, and colon).It also has poorer mental health outcomes and reduced quality of life.
Myocardial contraction and relaxation is a complex process involving longitudinal, circumferential, radial and torsional forces. Electrical activation in the normal heart typically occurs quickly within 40 ms via conduction through the Purkinje network and is associated with synchronous regional mechanical contraction.
So this study aimed to evaluate effect of BMI on LV electromechanical delay among adults with no history of cardiac disease.
