许多急性肾炎(AGN)患者有心衰的症状和体征。但不清楚是心肌功能被抑制,还是起因于循环液体负荷过度,或别的因素(例如高血压)。为此,作者用超声心动图研究一组AGN患儿的心脏状态。患者和方法:共研究14例链球菌后AGN患儿。全部有典型的AGN体征,包括血尿、蛋白尿、水肿。血沉增快,抗O增高,补体3降低。入院时全部作心电图和胸片检查。在入院次日(全部),出院时(8例)和出院后5个月(全部)作超声心动图检查。常规检查主动脉、左房、左室、室间隔、右室和心包。以计算左室射血部分和左室缩小部分的百分率来估计左室收缩状态。在主动脉辦水平测量左房和主动脉大小。在收缩末期回声图上,从主动脉后壁前缘到
Many patients with acute nephritis (AGN) have symptoms and signs of heart failure. It is unclear whether myocardial function is suppressed, however, or due to overloaded circulatory fluid, or other factors (such as high blood pressure). For this reason, the authors used echocardiography to study the cardiac status of a group of AGN children. Patients and Methods: A total of 14 children with AGN after streptococcal disease were studied. All have typical signs of AGN, including hematuria, proteinuria, edema. ESR faster, anti-O increased complement 3 decreased. Admission for all ECG and chest X-ray examination. Echocardiography was performed on the day after admission (all), at discharge (8 cases) and 5 months after discharge (all). Routine examination of the aorta, left atrium, left ventricle, septum, right ventricle and pericardium. The left ventricular systolic state was estimated by calculating the percentage of left ventricular ejection fraction and left ventricular fractionation. Measure the size of the left atrium and the aorta in the aorta. In the end systolic echo map, from the aortic posterior wall to the front edge
