16层螺旋 CT 冠状动脉钙化积分在冠心病诊断中的应用价值研究

摘要

Objective To investigate the value of coronary artery calcification score with16 slice spiral CT in the diagnosis of coronary heart disease .Methods A total of 35 cases patients with coronary heart disease admitted to our hospital from August 2013 to August 2015 were selected as the observation group ,and 35 patients with non-coronary heart disease were selected as con-trol group .Two groups of patients were performed of coronary artery calcification score with 16 slice spiral CT ,and coronary artery calcification score and total score of the two groups were compared .Results The scores of right coronary artery ,left anterior de-scending branch ,left anterior descending artery ,left anterior descending artery ,left main stem and total calcification score in the ob-servation group were significantly higher than those in the control group (P< 0 .05) .Condition of vascular calcification was as fol-lowing :the rate of patients with severe calcification was the highest in the observation group (88 .57% ) ,and the rate of patients without calcification in control group was the highest (77 .14% ) .Meanwhile ,the rates of patients without calcification and patients with a little calcification of the observation group were significantly lower than that of the control group (P< 0 .05) .The rate of pa-tients with severe calcification in the observation group was significantly higher than that in the control group (P< 0 .05) .Conclu-sion Coronary artery calcification score with 16 slice spiral CT can help to clarify the degree of calcification in patients with coro-nary heart disease ,which has higher clinical value and could be used for screening and diagnosis of coronary heart disease .%目的：探讨16层螺旋 CT 冠状动脉钙化积分对于冠心病诊断的应用价值。方法选择2013年8月至2015年8月在该院收治的35例冠心病患者作为观察组，另选择同期收治的35例非冠心病患者作为对照组。两组患者均行16层螺旋 CT 冠状动脉钙化积分检查，观察两组患者冠状动脉各分支钙化积分及总积分情况，并比较两组患者冠状动脉钙化情况。结果观察组右冠状动脉、左前降支、左回旋支、左主干及总钙化积分均显著高于对照组（P＜0．05）。血管钙化程度比较：观察组重度钙化百分比最高（88．57％）；对照组无钙化者百分比最高（77．14％）；观察组无钙化、少量钙化患者百分比显著少于对照组，差异有统计学意义（P＜0．05）。观察组重度钙化者百分比显著高于对照组，差异有统计学意义（P＜0．05）。结论16层螺旋 CT 冠状动脉钙化积分有助于明确冠心病患者钙化程度，临床诊断价值较高，适用于冠心病的筛查和诊断。
