目的:评价急性心肌梗死(AMI)造影的特点,比较不同年龄组之间的差剃。方法:本文搜集了自2004年4月至2006年6月确诊AMI并于发病12小时内进行冠脉造影检查的病例。分析造影提示的梗塞相关血管病变、其他血管病变的性质和特点,同时分析短期预后。结果:本研究共有118个病人入选。按年龄共分两组:其中>50岁为第1组,≤50岁为第2组。其中>50岁占81.4%,余下的年龄≤50岁。冠脉相对正常的病变第2组比第1组更多见,P<0.05,差别显著。以固定狭窄≥50%为标准计算,分析LM、LAD、LCX、RCA4支主要血管受累情况,第1组平均受累血管(2.3±0.9)支,第2组为(1.9±0.8)支,P<0.05,2组之间差别显著。共死亡6例,均为第1组。结论:本文研究提示AMI年轻病人病变程度轻于相对年长人群,且短期预后好。
OBJECTIVE: To evaluate the characteristics of acute myocardial infarction (AMI) contrast and to compare the differences between different age groups. Methods: This article collected from April 2004 to June 2006 diagnosed AMI and within 12 hours of onset of coronary angiography cases. Analysis of angiography suggestive of infarct-related vascular lesions, the nature and characteristics of other vascular lesions, while analysis of short-term prognosis. Results: A total of 118 patients were enrolled in this study. There are two groups by age:> 50 years old is group 1, and 50 years old is group 2. Of which> 50 years old accounted for 81.4%, the remaining age ≤ 50 years old. Coronary lesions relatively normal group 2 more than the first group, P <0.05, significant difference. The main vascular involvement of LM, LAD, LCX and RCA4 were analyzed with fixed stenosis≥50%. The average vessel involvement in group 1 was (2.3 ± 0.9), in group 2 (1.9 ± 0.8), P < There was a significant difference between 0.05 and 2 groups. A total of 6 cases of death, are the first group. CONCLUSIONS: This study suggests that young patients with AMI have a lesser degree of disease than their older counterparts and have good short-term prognosis.
