目的：探讨高原ＳＬＥ临危期心血管损害特征，为临床救治提供依据；材料与方法：总结高原ＳＬＥ病死组临危期、存活组活动期各３０例资料，常规测量ｘ线片心血管径线、分析心脏Ｂ超有关参数，进行统计学处理；结果：①活动期心影增大以右室或右室右房内径增大和心包积液为主，受累部位较局限；②临危期损害趋向多部位以至全心性，范围广泛而严重；③早期心脏损害多数始于右室，进而以右房、左室的顺序发展；④上腔静脉持续性增宽提示预后不良。结论：高原ＳＬＥ临危期心脏损害包括结构与功能多个方面，临床除控制病情活动外，应积极纠正心衰，前期氧疗能使临危期后移。
Objective: To investigate the characteristics of cardiovascular damage during the critical stage of SLE in plateau, and to provide the basis for clinical treatment.Materials and methods: To summarize the data of 30 cases of threatened and survivors active in the SLE group, routinely measure the cardiovascular diameter of the X-ray film, The parameters of heart B ultrasound, statistical analysis; Results: ① active period increased to the right ventricle or right ventricular right ventricular diameter and pericardial effusion, the more affected parts more limited; Whole heart, a wide range and serious; ③ most of the early heart damage began in the right ventricle, and then to the right atrium, left ventricular order; ④ superior vena cava persistent widening prompted a poor prognosis. Conclusion: In the plateau, the risk of heart damage during SLE is composed of many aspects of structure and function. In addition to controlling disease activities, heart failure should be actively corrected.
