72例2型糖尿病患者超声心动图分析

目的通过对72例2型糖尿病（diabetes mellitus，DM）患者超声心动图分析，探讨糖尿病患者心脏形态及功能的改变，为临床诊治提供参考。方法72例血糖控制不佳2型糖尿病患者，糖尿病病程〈5年为DM1组（42例），≥5年为DM2组（30例）。应用超声心动图测量心腔大小、室壁厚度、左室收缩舒张功能，并观察心肌回声。结果72例2型糖尿病患者中，心腔增大48例，室壁增厚19例，心肌回声增强11例，左室舒张功能降低58例，左室收缩功能降低9例。结论糖尿病患者其内环境的紊乱可导致心肌损害，应用超声心动图检查可早期、无创、准确地反映心内结构和功能的改变，为临床及时诊治提供帮助。

Analysis on echocardiography of 72 patients with type 2 diabetes mellitus

Objective To analyze the echocardiography of 72 patients with type 2 diabetes meUitus and explore the changes of the cardiac morphous and function. Methods Seventy-two patients with type 2 diabetes mellitus whose blood glucose were not controlled very well were divided into DM1 group （n =42） and DM2 group （n =30）. The disease course of patents in DM1 group were less than 5 years , but those in the DM2 group were more than 5 years. The echoeardiography was used to measure the size of cardiac chamber, the myocardium thickness and left ventricular systolic and diastolic function and to observe the resonance of myocardium. Results Among 72 patients, cardiac chamber dilation were found in 48 patients, myocardium thickening in 19 patients , echo enhancement in 11 patients , left ventricular diastolic function decline in 58 patients and left ventricular systolic function decline in 9 patients. Conclusion The disorder of the internal environment can lead to myocardial damage. Echocardiography can reflect the change early, accurately and non-invasively, and then offer the information to clinical therapy.
