目的探讨KAMIR危险评分在非ST段抬高型心肌梗死(NSTEMI)患者冠状动脉病变程度评估中的作用。方法应用KAMIR评分模型对同济大学附属第十人民医院2015—2016年收治的112例NSTEMI患者进行危险度评分,并依据分值将患者区分为低危组、中危组及高危组;记录各组患者冠脉造影结果,以Gensini法对患者造影图像进行积分,并分析KAMIR危险评分与冠状动脉病变血管数量及Gensini积分结果的相关性。结果 KAMIR评分结果为高危组的患者中,三支病变发生率显著高于低危及中危组患者,其冠状动脉图像Gensini积分亦显著高于低危及中危组患者。结论 KAMIR危险评分能够反映NSTEMI患者冠状动脉病变严重程度,可用于NSTEMI患者冠脉病变的早期评估。
Objective To investigate the role of KAMIR risk score in assessing the severity of coronary lesions in patients with non-ST-segment elevation myocardial infarction (NSTEMI). Methods The KAMIR score model was used to assess the risk of NSTEMI among 112 patients with NSTEMI admitted to the Tenth People’s Hospital affiliated to Tongji University from 2015 to 2016. The patients were divided into low risk group, moderate risk group and high risk group according to the scores. The results of coronary angiography were analyzed by Gensini method and the correlation between KAMIR risk score and the number of coronary artery lesion and Gensini integral was analyzed. Results Among the patients with high KAMIR score, the incidence of three lesions was significantly higher than those in low-risk and intermediate-risk patients. The Gensini scores of coronary arteries were also significantly higher than those in low-risk and intermediate-risk patients. Conclusion KAMIR risk score can reflect the severity of coronary artery disease in patients with NSTEMI and can be used for early assessment of coronary artery disease in patients with NSTEMI.
