多层螺旋CT冠脉钙化积分诊断冠心病及风险预测的临床价值

目的:探讨多层螺旋CT冠脉钙化积分在冠心病的诊断及早期风险性预测中的临床价值.材料和方法:总结90例受检者资料,分析多层螺旋CT冠脉钙化积分与其年龄、血脂及心电图的关系.结果:多层螺旋CT冠脉钙化积分与受检者的年龄、血脂及心电图的缺血改变具有显著的正相关:年龄越大、血脂越高,钙化发生率、钙化的程度及平均钙化积分值越高;随着钙化积分的增高,心电图缺血改变的发生率逐渐增高.结论:多层螺旋CT冠脉钙化积分检查经济、方便、无创,适用于冠心病的筛查及风险性预测.

The Clinical Value of Coronary Calcification Score by Multi-slice Spiral CT in the Diagnosis and Risk Prediction of Coronary Heart Disease

Purpose: To study the clinical value of coronary calcification score by multi-slice spiral CT in the diagnosis and risk prediction of coronary heart disease. Materials and Methods: Multi-slice spiral CT (Lightspeed Plus, GE) was used for the coronary calcification score analysis in 90 persons. The relationship between coronary calcification score and age, blood lipide and ECG was evaluated. Results: The coronary calcification score by multi-slice spiral CT had a positive correlation with the age, blood lipide and ECG of objects. The elder the age and/or the higher the blood lipide, and also the rate and degree of coronary calcification, The average coronary calcification score was higer in elder patients. The incidence of ischemic ECG change increased with the increasing of the coronary calcification score. Conclusion: Multi-slice spiral CT is a cheap, convenient and non-invasive method for coronary calcification score, screening and risk prediction of coronary heart disease.
