摘要
目的 探讨常规冠脉斑块参数与CT-血流储备分数(CT-FFR)之间的关系.方法 选择2021年1月-12月在连云港市第一人民医院进行冠脉CT血管成像(CCTA)检查,并在1个月内进行冠脉造影患者144例.以CT-FFR作为血流动力学是否异常的评价标准,根据CT-FFR值分组,将CT-FFR＞0.8设为CT-FFR阴性组,CT-FFR≤0.8设为CT-FFR阳性组,分析CT-FFR阳性与CT-FFR阴性患者冠脉特征的关系.结果 CT-FFR阳性组的钙化积分高于CT-FFR阴性组,CT-FFR阳性组的病变长度大于CT-FFR阴性组,差异有统计学意义(P＜0.05);两组狭窄程度比较,差异有统计学意义(P＜0.05);弥漫性病变与非弥漫性病变的CT-FFR值比较,差异有统计学意义(P＜0.05).结论 冠状动脉狭窄、病变长度和钙化积分是影响冠心病患者的冠状动脉血流动力学异常的重要因素.
Abstract
Objective To investigate the relationship between conventional coronary plaque parameters and CT-fractional flow reserve(CT-FFR).Methods From January to December 2021,coronary CT angiography(CCTA)was performed in the First People's Hospital of Lianyungang,and 144 patients with coronary angiography were performed within one month.CT-FFR was used as the evaluation standard of whether hemodynamics was abnormal.According to the CT-FFR value,CT-FFR＞0.8 was set as CT-FFR negative group,and CT-FFR ≤0.8 was set as CT-FFR positive group.The relationship between CT-FFR positive and CT-FFR negative patients in coronary artery characteristics was analyzed.Results The calcification score of CT-FFR positive group was higher than that of CT-FFR negative group,and the lesion length of CT-FFR positive group was longer than that of CT-FFR negative group(P＜0.05).There was significant difference in the degree of stenosis between the two groups(P＜0.05).There was significant difference in CT-FFR value between diffuse lesions and non-diffuse lesions(P＜0.05).Conclusion Coronary artery stenosis,lesion length and calcification score are important factors affecting coronary hemodynamic abnormalities in patients with coronary heart disease.
