目的 比较多巴酚丁胺负荷超声心动图与心电图对飞行人员冠心病的诊断价值。方法 对36例飞行人员进行多巴酚丁胺负荷超声心动图及心电图检查,并将结果进行对比分析。结果 这两种无创性检查诊断冠心病的敏感性分别为:100％、50％(P<0.01);特异性分别为97％、100％;准确性分别为:97％、94％。结论 多巴酚丁胺负荷超声心动图对于诊断冠心病具有较高的敏感性、特异性,可作为飞行员筛查冠心病的常规检查方法,多巴酚丁胺负荷心电图可作为多巴酚丁胺负荷超声心动图诊断的补充。
Objective To compare the diagnostic value of dobutamine stress echocardiography and electrocardiogram on coronary heart disease in pilots. Methods Thirty-six pilots were subjected to dobutamine stress echocardiography and electrocardiogram examination, and the results were compared. Results The sensitivity of these two noninvasive tests in diagnosis of coronary heart disease were 100% and 50%, respectively (P <0.01). The specificity was 97% and 100% respectively. The accuracy was 97% and 94% respectively. Conclusions Dobutamine stress echocardiography is highly sensitive and specific for the diagnosis of coronary heart disease. It can be used as a routine method for pilots screening coronary heart disease. Dobutamine stress electrocardiogram can be used as dobutamine Supplementation of stress echocardiography.
