Summary

This prospective study intends to explore the change of cardiac structure and function in the cohort of overweight or obesity patients, and determine the impact of clinical characteristics on cardiac remodeling and mechanics.

Detailed description

Obesity significantly increases the risk for heart failure. Early detection of preclinical cardiac dysfunction in overweight or obesity and understanding its association with insulin resistance are of great importance.Recently, a novel technique for myocardial work (MW) assessment has been introduced to evaluate myocardial performance. To date, change of MW has been described in several cardiac conditions including dilated cardiomyopathy, significant coronary arterial diseases, and hypertrophic cardiomyopathy, which implies regional or global myocardial dysfunction. In this study, we aimed to explore the alteration of MW in overweight or obese adults and to determine whether insulin resistance or other clinical risk factors may impact myocardial mechanics before impairment of systolic function.

Conditions

• Overweight and Obesity

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Myocardial work was estimated from left ventricular pressure-strain loop derived from speckle tracking echocardiography and non-invasive brachial artery cuff pressure	Baseline and follow-up examination of echocardiography is to be performed on study subjects.
