Overview
Brief Summary
This is a single-center, prospective, observational study to explore the clinical features and risk factors of impaired cardiac function detected by two-dimensional speckle tracking echocardiography in patients with diabetes mellitus. The risk factors include traditional cardiovascular risk factors, bone metabolism hormones, sex hormones, adrenal and pituitary hormones, and novel serum biomarkers.
Detailed Description
Cardiovascular complications are a leading cause of death in patients with diabetes mellitus. However, early cardiovascular disease screening presents several challenges, particularly for those who have no cardiovascular symptoms. Novel imaging techniques, such as tissue Doppler imaging and speckle tracking echocardiography, allow for the more frequent detection of early subclinical left ventricular systolic dysfunction in asymptomatic patients with diabetes. Based on speckle tracking echocardiography and other techniques, this study evaluated cardiovascular function in diabetic subjects to achieve the following objectives: A) Investigate the clinical characteristics of diabetic patients with early cardiovascular function impairment. B) Investigate the role of traditional cardiovascular risk factors, bone metabolism hormones, sex hormones, adrenal and pituitary hormones in diabetic patients with early cardiovascular function impairment. C) Explore novel biomarkers of early cardiovascular dysfunction in diabetic patients.
