冠心病易侵犯右或左冠状动脉近侧4cm 处以及左冠状动脉的前降支或左旋支。病变是否累及较小血管和分支尚有异议。我们通过检测冠心病患者血清及尿中β_2-微球蛋白(β_2-MG)的变化,了解有无小血管病损。对象与方法研究对象:为我院1991年4月～1992年4月住院病人,通过病史,体检和有关检查诊断为冠心病患者,其中男44例,女5例。平均年龄67.2±0.8岁。诊断标准:均按1981年全国冠心病、高血压普查预防座谈会修订诊断标准诊断。方法:晨空腹取静脉血,分离血清后置于-20℃
Coronary heart disease is easy to invade the right or left coronary artery 4cm proximal and left anterior descending coronary artery or left circumflex artery. Whether the lesions involve smaller vessels and branches is still objectionable. We detected the presence or absence of small vessel lesions by detecting the changes of β_2-microglobulin (β_2-MG) in serum and urine of patients with coronary heart disease. Subjects and Methods Subjects: Inpatients from April 1991 to April 1992 in our hospital were diagnosed as coronary heart disease by medical history, physical examination and related tests, including 44 males and 5 females. The average age was 67.2 ± 0.8 years. Diagnostic criteria: according to the 1981 National Coronary Heart Disease, Hypertension screening seminars to amend diagnostic criteria diagnosis. Methods: Take morning fasting venous blood, after separation of serum at -20 ℃
