Official title: Association of Triglyceride-glucose Index With Cardiac Hemodynamics and Cardiovascular Risk Assesment in Obese Patient.

Status Not yet recruiting

Clinical Trial Summary

1) To estimate the prevelance of IR in obese patients based on TYG index . 2) To screen early cardiovascular abnormalities in obese asymptomatic patients using conventional echocardiography and electrocardiogram . 3) To detect association of cardiovascular hemodynamics with TyG index . Assess cardiovascular risk in obese patients .

Clinical Trial Description

Obesity has been a health problem of growing significance all over the world; its prevalence is increasing in both developed and developing countries . According to WHO data, 39% of the global population above 18 years of age are overweight and of these, 13% are obese. Obesity is a chronic (long-term) medical disease. Both overweight (BMI >25 kg/m2) and obesity defined as a ( Body Mass Index, or BMI, of >30 kg/m2) are associated with an increased risk of cardiovascular diseases. This is a consequence on the one hand of obesity itself and on the other hand of associated medical conditions (hypertension, diabetes, insulin resistance ,stroke ,sleep apnea, osteoarthritis, gallstones, high cholesterol, gout, and certain types of cancer ) . Obesity produces a variety of hemodynamic alterations that may cause changes in cardiac morphology which predispose to left and right ventricular dysfunction. Various neurohormonal and metabolic alterations commonly associated with obesity may contribute to these abnormalities of cardiac structure and function. Cardiovascular diseases, including heart failure (HF), atrial fibrillation (AF), and coronary artery disease (CAD), are often associated with obesity. The duration of obesity has a direct impact on the incidence of cardiovascular disease.The triglyceride-glucose (TyG) index is the logarithmized product of fasting triglycerides and fasting glucose and has been proposed as the alternative indicator of IR ( with sensitivity 96.5 % and specificity 85% ) due to its relevance to lipotoxicity and glucotoxicity compared to Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), which is expensive due to insulin measurement .TyG index has demonstrated a close relationship with cardiometabolic outcomes, namely diabetes, arterial stiffness, hypertension, cardiovascular disease (CVD), stroke and obesity-related cancers in previous studies. ;
