64排螺旋CT冠脉成像诊断冠心病的临床分析

目的探讨64排螺旋CT冠脉成像诊断冠心病的价值。方法对80例患者同时行64排螺旋CT冠脉成像和选择性冠状动脉造影检查。以选择性冠状动脉造影检查为金标准,评价64排螺旋CT冠脉成像诊断冠心病的灵敏度、特异度、阳性预测值、阴性预测值。结果 64排螺旋CT冠脉成像诊断冠状动脉狭窄≤50%、50%～70%和≥70%的敏感性分别为78.1%、79.1%、90.2%,特异性分别为96.9%、97.7%、98.2%,阳性预测值分别为79.4%、82.0%、83.8%,阴性预测值分别为96.7%、97.2%、99.0%。结论 64排螺旋CT诊断冠状动脉狭窄可作为冠心病的无创性检查方法之一。

The clinical analysis of coronary heart disease diagnosis with 64-slice spiral CT coronary angiography

Objective To explore the value of 64-slice spiral CT coronary angiography （MSCTCA） in diagnosis ot coronary heart disease. Methods A trial of 80 patients who were diagnosed coronary artery disease were taken MSCTCA and coro- nary angiography （CAG） . Taking CAG as gold standard, evaluate the sensitivity, specificity, positive and negative predictive value of MSCTCA in diagnosis of coronary heart disease. Results The sensitivity, specificity, positive and negative predictive values to identify ≤50% 50%-70%和≥70% stenosis of coronary artery with MSCTCA were 78.1%, 79.1%, 90.2% and 96.9 %, 97.7%, 98.2% and 79.4%, 82.0%, 83.8% and 96.7%, 97.2%, 99.0% respectively. Conclusion MSCTCA can be regard as one of no-trauma methods to diagnose coronary artery disease.
