H型高血压患者冠状动脉病变诊断中冠状动脉CT技术应用的价值

The Application Value of CT Technique in the Diagnosis of Coronary Artery Disease in Patients with H Type Hypertension

目的探讨研究H型高血压患者冠状动脉病变诊断中冠状动脉CT技术应用的价值。方法选取我院收治的符合入选标准的原发性高血压患者120例,均行冠状动脉CT、冠脉造影,以及同型半胱氨酸(Hcy)水平检测。依据Hcy水平将所有患者分为H型高血压组和单纯高血压组,对比CT和冠脉造影关于冠状动脉病变检查结果,并分析CT技术在H型高血压患者冠状动脉病变诊断中的应用价值。结果 CT检测技术和冠脉造影检查结果中,冠状动脉狭窄阳性率和钙化率差异均无统计学意义(P>0.05);以冠脉造影结果为"金标准",CT检测技术在冠状动脉狭窄和钙化中阳性预测值均为100.00%,且灵敏度、准确率和阴性预测值均比较高;H型高血压组患者冠状动脉狭窄阳性率(72.06%)较单纯高血压组(50.00%)显著升高(P<0.05),且前者钙化率(51.47%)较后者(28.85%)显著升高(P<0.05)。结论 H型高血压患者采用CT检测技术对冠状动脉病变进行诊断和冠脉造影结果相近,且灵敏度、准确率、阳性和阴性预测值均比较高,具有较高的推广应用价值。

Objective To discuss and study the application value of CT technique in the diagnosis of coronary artery disease in patients with H type hypertension. Methods 120 cases of patients with with essential hypertension who were eligible for inclusion criteria treated in our hospital were selected and treated with CT and coronary angiography, and detected the homocysteine（Hcy） levels. According to the Hcy levels, all patients were divided into H type hypertension group and simple hypertension group. The results were compared with CT and coronary angiography. The value of CT in the diagnosis of coronary artery lesions in patients with H type hypertension was analyzed. Results Results In the results of CT test and coronary angiography, there were no significant differences between the positive rates of coronary artery stenosis and calcification rates（P〈0.05）.The results of coronary angiography were noted as the ＂gold standard＂, and the positive predictive values of CT test in coronary artery stenosis and calcification were 100.00%, of which the sensitivities, accuracies and negative predictive values were higher.The the positive rate of coronary artery stenosis in the H type hypertension group（72.06%） was significantly higher than that in the simple hypertension group（50.00%）（P〈0.05）, and the calcification rate of the former（51.47%） was significantly higher than that of the latter（28.85%）（P〈0.05）. Conclusion The results of CT detection technique for the diagnosis of coronary artery disease are closed to those of coronary angiography,and the sensitivity, accuracy, positive and negative predictive values are relatively high, which has a high value of popularization and application.
