目的:探讨冠心病患者冠状动脉(冠脉)病变SYNTAX积分的影响因素.方法:选取101例接受择期冠脉造影并行经皮冠脉内支架植入术治疗的冠心病患者(包括稳定型心绞痛和不稳定型心绞痛患者),通过相关性分析及单因素方差分析其冠脉病变SYNTAX积分的影响因素.结果:101例患者SYNTAX积分为(11.38±6.61),相关性分析发现SYNTAX积分与总胆固醇(r=0.279,P=0.005)、低密度脂蛋白胆固醇(r=0.247,P=0.013)、载脂蛋白B(r=0.270,P=0.006)、载脂蛋白B/载脂蛋白A1比值(r=0.246,P=0.013)存在正相关性.与高密度脂蛋白胆固醇、载脂蛋白A1无统计学相关性.未发现性别、高血压、糖尿病、吸烟史、脑血管病史、冠脉造影术前应用阿司匹林应用超过1个月等因素对冠脉SYNTAX积分有影响.结论:冠脉病变复杂程度与总胆固醇、低密度脂蛋白胆固醇、载脂蛋白B、载脂蛋白B/载脂蛋白A1比值水平有关,而与高密度脂蛋白胆固醇和载脂蛋白A1水平无明显相关性.“,”Objective:To investigate the influencing factors of SYNTAX scores in patients with coronary heart disease.Method:One hundred and one patients with coronary heart disease (including stable angina and unstable angina) underwent elective coronary angiography and percutaneous coronary stent implantation were participated.The influencing factors of SYNTAX score was analyzed by single-factor ANOVA analysis.Result:The SYNTAX score of 101 patients was 11.38 ± 6.61.Correlation analysis showed that there was a positive correlation between SYNTAX score and total cholesterol (r=0.279,P=0.005),low-density lipoprotein cholesterol (r=0.247,P=0.013),apolipoprotein B (r =0.270,P =0.006),apolipoprotein B / apolipoprotein A1 ratio (r =0.246,P =0.013).There was no statistical correlation between SYNTAX score and high-density lipoprotein cholesterol,apolipoprotein A1.Conclusion:The complexity of coronary artery correlates with the levels of total cholesterol,low-density lipoprotein cholesterol,apolipoprotein B and apolipoprotein B / apolipoprotein A1 ratio.
