【摘要】：目的应用实时三维超声心动图(RT-3DE)和斑点追踪技术(STI)评价Ⅱ型糖尿病(2DM)患者无心血管疾病症状期左房(LA)结构和功能的变化。方法收集37例2DM患者和30例健康对照者,应用RT-3DE获取LA最大容积(Vmax)、最小容积(Vmin)及收缩前容积(Vpre A),并计算LA总射血分数(TEF)、膨胀指数(EI)、主动射血分数(AEF)及被动射血分数(PEF)。应用STI获取LA负向峰值应变(NS)、正向峰值应变(PS)。比较两组统计学差异。结果 2DM组LAVmax、LAVmin及Vpre A显著增加,LATEF、LAEI及LAPEF显著减低;LAAEF显著增加,LANS绝对值显著增加,LAPS值显著减低。结论 2DM患者在无心血管疾病症状期LA的结构和功能已受到影响,进而影响LA对左室舒张功能的代偿调节作用。
[Abstract]:Objective to evaluate the structural and functional changes of left atrial Flae (LAA) in patients with type 2 diabetes mellitus (DM) without cardiovascular symptoms by using real-time three-dimensional echocardiography (RT-3DE) and speckle tracing technique (STI). Methods A total of 37 patients with 2DM and 30 healthy controls were selected to obtain LA Vmaxian, minimum Vmin and presystolic Vpre An by RT-3DE. The total ejection fraction of LA, the expansion index, the active ejection fraction and the passive ejection fraction were calculated. The negative peak strain of LA was obtained by STI, and the positive peak strain was obtained. Statistical differences were compared between the two groups. Results in 2DM group, LAVmax2DM LAVmin and Vpre A were significantly increased and LATEFL LAEI and LAPEF were significantly decreased. LAAEF was significantly increased and LANs absolute value was significantly increased and laps value was significantly decreased. Conclusion the structure and function of LA have been affected in patients with 2DM during the period of no cardiovascular disease, and the compensatory effect of LA on left ventricular diastolic function is affected.
