Abstract

Childhood obesity complications are increasing year by year with the continuous growth of obesity incidence rate.Studies have shown that the increased risk of cardiovascular disease (coronary atherosclerosis, heart failure and arrhythmia) is closely related to obesity.Additionally, obesity is also related to the occurrence and development of myocardial hypertrophy, ventricular systolic dysfunction and reduced diastolic compliance.The diastolic function of simple obese children is significantly lower than that of normal weight children.There are many pathological mechanisms of cardiomyopathy caused by obesity, including insulin resistance, inflammation, oxidative stress, lipotoxicity, apoptosis and mitochondrial autophagy.However, the precise molecular mechanism by which obesity leads to changes in cardiac structure and function remains unclear.This article briefly reviews the possible molecular mechanisms of obesity-induced myocardial remodeling, and provides theoretical basis for the prevention and treatment of obesity related cardiomyopathy in children.
