摘要
冠心病早期多无症状或不典型 ,现用的各种无创性检查方法确诊率低 ( <3 5% ) ,用冠状动脉造影 (Coronaryangiography,CAG)检查 1 2例飞行员 ,8例冠心病临床可疑 ,5例CAG正常可排除冠心病。 3例诊断为X综合征 ,其中 2例有较典型的心绞痛症状及ECG心肌缺血改变 ,1例有不典型心绞痛症状 ,SET、RMI均为阳性 ,CAG冠脉末稍细 ;这3例CAG无冠脉明显狭窄 ,均符合小冠状动脉病变。另 4例是急性心肌梗塞 (AMI)患者 ,CAG均显示冠脉明显狭窄。CAG对冠心病的确诊有重要价值 ,与无创性检查方法对比分析 ,更清楚地了解其相关性与临床意义。
Coronary heart disease (CHD) is usually asymptomatic or presents with a typical symptoms at the early stage with low diagnostic accuracy (<35% )rate,if the current noninvasive methods are used.In this study, 8 pilots with suspected CHD and 4 pilots with acute myocardial infarction were examined with coronary angiography (CAG ).Out of the 8 subjects with suspected CHD, 5 had normal CAG and were qualified for flying, 3 were diagnosed as X syndrome.Different degree of coronary stenosis were demonstrated by CAG in the 4 cases of myocardial infarction.The results indicated that CAG still plays important role in diagnosis of CHD whereas various noninvasive examinations,when compared and correlated with CAG also have certain clinical significance.
