Echocardiographic Study of the Coronary Sinus in the Indeterminate Form of Chagas Disease

Abstract INTRODUCTION: We investigated the occurrence of coronary sinus abnormalities in the indeterminate form of Chagas disease (CD). METHODS: Differences between the maximum and minimum diameters of the coronary sinus (∆%) on echocardiography were evaluated in individuals with the indeterminate form of CD (n=14) and those without (n=16) CD. The association of the difference with abnormalities detected by echocardiography and myocardial scintigraphy was assessed. RESULTS: The mean Δ% values did not differ significantly between the groups. There was no correlation of the measurements with echocardiographic and myocardial scintigraphy findings. CONCLUSIONS: The coronary sinus evaluation revealed no differences between the groups.

摘要 引言：本研究探究了不定型恰加斯病（Chagas disease, CD）患者的冠状窦异常发生情况。
方法：本研究纳入14例不定型恰加斯病患者与16例非恰加斯病受试者，采用超声心动图（echocardiography）检测受试者冠状窦（coronary sinus）的最大与最小直径差值百分比（∆%），并评估该差值与超声心动图、心肌闪烁显像（myocardial scintigraphy）检出异常的相关性。
结果：两组受试者的平均∆%值无显著统计学差异；该测量值与超声心动图及心肌闪烁显像结果均无相关性。
结论：冠状窦评估未发现两组间存在差异。
