摘要:


(山东大学 1. 医学院, 济南 250012; 2. 附属千佛山医院心内科, 济南 250014)摘要:目的探讨急性心肌梗死(AMI)发病前伴有糖尿病、高血压对心肌梗死范围影响的程度。方法选取2006年6月~2008年6月收住院的AMI患者62例,根据AMI发病前是否伴有合并症分为3组,其中伴有糖尿病18例为A组;伴有高血压21例为B组;不伴有糖尿病和高血压23例为C组。测定AMI患者血清肌钙蛋白T(cTnT)、肌酸激酶MBmass(CKMBmass)、肌酸激酶MB活性(CKMBact)的动态变化情况。结果①血清cTnT、CKMBmass、CKMBact出现异常值的时间,A组患者分别平均为3.9、2.9和3.0?h;B组患者分别平均为3.5、1.6和2.3?h;C组患者分别平均为2.8、1.3和1.7?h;②上升至峰值的时间,A组患者分别平均为38.9、28.5和32.4?h;B组患者分别平均为35.4、26.7和29.5?h;C组患者分别平均为30.5、18.2和20.7?h;③自峰值下降至正常的时间,A组患者分别平均为78.5、72.6和63.2?h;B组患者分别平均为58.7、52.4和41.7?h;C组患者分别平均为62.5、58.6和52.5?h;④根据动态变化计算心肌梗死量,A组患者分别平均为45.2 cTnTg、42.5 CKMBmassg、45.7 CKMBactg;B组患者分别平均为40.8 cTnTg、37.4 CKMBmassg、39.2 CKMBactg;C组患者分别平均为31.4 cTnTg、28.7 CKMBmassg、31.6 CKMBactg。结论AMI发病前伴有糖尿病、高血压的患者病情重,并发症发生率高,心肌梗死范围明显增大。

Abstract:

To investigate the effect of incidence of acute myocardial infarction (AMI) associated with diabetes mellitus or hypertension on myocardial infarction size.  Methods62 patients with AMI hospitalized from June 2006 to June 2008 were divided into three groups according to complications: group A contained 18 patients who had AMI with diabetes mellitus, group B contained 21 patients who had AMI with hypertension, and group C contained 23 patients who had AMI without diabetes mellitus or hypertension. Then cTnT, CKMBmass and CKMBact were kinetically measured in these patients. Results①Abnormal changes of serum cTnT, CKMBmass, and CKMBact levels appeared at 3.9, 2.9, 3.0?h respectively in group A, while at 3.5, 1.6, 2.3?h in group B, and at 2.8, 1.3, 1.7?h respectively in group C. ② The maximal values of cTnT, CKMBmass and CKMBact appeared at 38.9, 28.5, 32.4?h in group A, at 35.4, 26.7, 29.5?h in group B, and at 30.5, 18.2, 20.7?h in group C. ③ cTnT, CKMBmass and CKMBact returned to the baseline levels at 78.5, 72.6, 63.2?h in group A, at 58.7, 52.4, 41.7?h in group B, and at 62.5, 58.6, 52.5?h in group C. ④ Quantity of injured myocardial in group A was 45.2 cTnTg, 42.5 CKMBmassg, and 45.7 CKMBactg; in group B was 40.8 cTnTg, 37.4 CKMBmassg, and 39.2 CKMBactg; ingroup C was 31.4 cTnTg, 28.7 CKMBmassg, and 31.6 CKMBactg. ConclusionsAMI patients complicated with diabetes mellitus and hypertension have highly critical conditions, which maybe attribute to an increased myocardial infarct size.
