Objective To explore the clinical value of 64 row spiral CT to disease characteristics of hypertension patients with coronary artery and evaluation of left heart function. Methods 120 patients with high blood pressure from September 2009 to December 2010 in our hospital were selected. According to the patient's blood pressure levels, all the patients were divided into three groups, high blood pressure level 1, level 2 and level 3 with 40 cases in each group, 40 healthy check-up patients were chosen as control group. 64 row spiral CT were used to cardiac imaging scan, the relationship on the disease characteristics of coronary artery, blood pressure and coronary artery disease and left heart function were analyzed. Results Mild and single pathological changes were found in high blood pressure level 1 group chiefly; double and three teams of lesions were found in high blood pressure level 3 group chiefly, the differences of LVEF.LVEDV.LVESV and LVMM among high blood pressure level 3 group and other groups were all statistically significant (all P < 0.05), except the LVSV. Conclusion The examination of 64 row spiral CT can make accurate judgement to the smooth and narrow degree of coronary artery patients, and can accurately evaluate left cardiac function, and can screen the patients in high blood pressure combined with suspected coronary heart disease.%目的 探讨64排螺旋CT对高血压患者冠状动脉病变特点以及左心功能评估的临床价值.方法 选择2009年9月～2010年12月我院收治的高血压患者120例,根据患者的血压水平将患者分为高血压1级、高血压2级以及高血压3级三组,每组各40例,另外选取健康体检者40例为对照组.使用64排螺旋CT进行心脏成像扫描,分析其冠状动脉的病变特点、血压与冠状动脉病变和左心功能的关系.结果 高血压1级组患者以轻度和单支病变为主,高血压3级阻患者双支和三支病变最多,且除每搏输出量(LVSV)外,高血压3级阻患者的左室射血分数(LVEF)、左室舒张末容积(LVEDV)、左室收缩末容积(LVESV)以及心肌质量(LVMM)与其他组对比,差异均具有统计学意义(P < 0.05).结论 64排螺旋CT检查可对患者冠状动脉的畅通以及狭窄程度做出准确判断,且可准确评价左心功能,可作为高血压患者可疑合并冠心病的临床筛查方法.
