THE HEART STRUCTURE AND FUNCTION CHANGES AND RELATED RISK FACTORS OF TYPE 2 DIABETIC PATIENTS / 现代医院

ABSTRACT

Objective To investigate the changes of cardiac structure and function in type 2 diabetes mellitus (T2DM), analyze the related risk factors of heart failure, and improve the awareness of the effect of diabetes on the heart. Methods Randomly selected 170 cases of T2DM patients As the object of study, 170 cases of non diabetic patients as con-trol group, according to whether complicated with heart failure were divided into heart failure patients and non heart failure patients.Comparison of each group left ventricular posterior wall thickness, left ventricular end diastolic diameter, left ven-tricular end systolic diameter, left ventricular ejection fraction, E/A ratio Differences, analysis of the related risk factors of heart failure by logistic regressive.Results T2DM group left ventricular posterior wall thickness, left ventricular end diastolic diameter and left ventricular end systolic diameter increased , Left ventricular ejection fraction decreased, E/A ratio de-creased, were statistically significant difference compared with the control group (p <0.05).These differences are mainly come from non heart failure patients.Logistic regression showed that factors in patients with diabetes duration, HbA1c, com-pliance and complications of hypertension, coronary heart disease, is a risk factor for heart failure complicated with T2DM (all p<0.01).These may be the risk factor for diabetic patients with heart failure.Conclusion Diabetes can cause cardiac remodeling, systolic and diastolic dysfunction maybe some T2DM patients.They did not show symptoms of heart failure in the clinical, but their Cardiac structure and function are abnormal.We should pay attention to the cardiac function examination and early evaluation, prevention of risk factors, to avoid the occurrence of heart failure.
