摘要(Abstract)：
<正>1临床资料患者女,68岁。主因"左足麻木2年,加重伴间歇性跛行半年"于2017年10月入北京大学第一医院。临床表现为间断左足麻木2年,近半年加重伴跛行,腰椎核磁示L1～S1椎间盘突出,为行手术收入骨科。既往乙型肝炎病毒表面抗原(hepatitis B surface antigen, HBsAg)阳性30年,糖尿病病史12年。否认高血脂、卒中、外周血管疾病史;否认吸烟史及心脏病家族史。入院查体:血压130/75 mmHg(1 mmHg=0.133 kPa),心率105次/分,双肺呼吸音清,未闻及啰音;心界不大,心律齐,各瓣膜听诊区未闻及杂音及心包摩擦音;未见异常血管征,双下肢无水肿。实验室检查示:心肌肌钙蛋白I(cardiac troponin I, cTnI)2.790 ng/ml(参考范围
