Abstract
Objective To evaluate the clinical value of echocardiography at rest in the diagnosis of coronary heart disease ( CHD ) and the related lesion artery. Methods A total of 165 patients with suspected CHD were examined with both echocardiography at rest and coronary angiography ( CAG ). With the CAG results as the diagnostic standard,the diagnostic accuracy was evaluated. The related lesion artery was concluded according to the regional wall motion abnormality( RWMA ). The patients with CHD were divided into two groups: myocardial infarction group and angina pectoris group. The diagnostic accuracy and its relationship with the different lesion artery were compared between two groups. Results ①The sensitivity, specificity, positive predictive value and negatitve predictive value of echocardiography at rest in the diagnosis of CHD were 46. 4% ,92. 5% ,95. 08% and 35. 57%,respectively. The sensitivities in the diagnosis of myocardial infarction and its related lesion artery were significantly higher than those of angina pectoris( P ＜ 0. 05 ). ②The sensitivity had a tendency to increase with the increased number of lesion artery, but there was no significant difference( P ＞ 0. 05 ). ③The sensitivity and the specificity for the left anterior descending( LAD )lesion tended to be higher than those for the left cir-cumflex( LCX )and the right coronary artery( RCA ),but there was no significant difference( P ＞0. 05 ). ④The proportion of severe lesion coronary artery(≥90% )in abnormal echocardiography group was significantly higher than that in normal group( P ＜ 0. 05 ). Conclusion Although echocardiography at rest has its limitations in the diagnosis of angina pectoris, it plays a very important role in the qualitative analysis and positioning diagnosis for myocardial infarction, and its value in evaluating the extent and severe degree of coronary artery lesion has to be paid more attention to.关键词
