老年人ST段水平延长对冠心病的诊断价值

Value of the Elderly ST Segment Level Extension in the Diagnosis of Coronary Heart Disease

目的讨论老年人ST段水平延长对冠心病的诊断价值。方法回顾性分析有心绞痛病史、冠状动脉造影确诊冠心病者56例为试验组。冠状动脉造影正常者56例为对照组。比较两组患者ST段水平延长的差异,并分析其对冠心病诊断价值。结果试验组患者ST段水平延长发生率为87.5%显著高于对照组26.8%,比较具有统计学差异(P<0.05);ST段水平延长诊断冠心病的敏感性为87.5%(49/56),特异性为73.2%(41/56),阳性预测值为76.6%(49/64),阴性预测值为85.4%(41/48),准确率为80.4%(90/112)。结论 ST段水平延长对冠心病诊断价值较高,具有较高的敏感性及特异性,值得临床选择。

Objective To investigate the value of the elderly ST segment extension on the diagnosis of coronary heart disease. Methods 56 cases of angina pectoris patients with coronary heart disease confirmed by coronary angiography were set as the test group,while 56 cases of angina pectoris patients without coronary heart disease confirmed by coronary angiography were set as the control group. A retrospective analysis on the two groups of patients was carried out. The differences of the ST segment level extension between the two groups were compared,and their value on the diagnosis of coronary artery disease was analyzed. Results The incidence of ST segment level extension on patients in test group is 87. 5 %,which is significantly higher than that in the control group( 26. 8%)( P < 0. 05). The sensitivity,specificity,positive predictive value,negative predictive value and accuracy rate of ST segment level extension in the diagnosis of coronary heart disease was 87. 5%( 49/56),73. 2%( 41/56),76. 6%( 49/64),85. 4%( 41/48),and 80. 4%( 90/112),respectively. Conclusion ST segment level extension showed very high value in the diagnosis of coronary heart disease with high sensitivity and specificity,and is worthy for clinical choice.
