摘　　要：目的研究血清脂蛋白a[Lp(a)]与二尖瓣环钙化及其二尖瓣功能障碍之间的潜在联系。方法收集2022年1月—2023年11月于亳州市人民医院心血管内科住院并行冠脉CT血管成像(CTA)患者的临床资料,共131例,根据图像分析,分为二尖瓣环钙化(MAC)组(62例)及正常组(69例)。收集患者基线资料包括年龄、性别、高血压、糖尿病、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、载脂蛋白A、载脂蛋白B、血清脂蛋白a、肌酐、尿酸、同型半胱氨酸、服用他汀史等。比较2组临床基本资料及发生二尖瓣狭窄及反流的差异,分析MAC的危险因素及MAC引起的相关二尖瓣疾病的风险。结果二尖瓣环钙化组及正常组的LDL-C、Lp(a)差异有统计学意义(P<0.001)。Logistic回归分析显示Lp(a)升高是MAC的独立危险因素(OR=1.256,95%CI:1.002~1.490,P=0.008)。重度MAC组与正常组、轻度MAC组、中度MAC组患者的Lp(a)水平差异均有统计学意义(P<0.05)。MAC组及正常组二尖瓣狭窄发生率差异无统计学意义[8.06%(5/62)vs.1.45%(1/69),P=0.165],但MAC组比正常组二尖瓣反流发生率高[17.74%(11/62)vs.4.35%(3/69),P=0.013]。结论Lp(a)水平升高是二尖瓣环钙化的危险因素之一,MAC可能增加二尖瓣反流风险,建议对MAC患者应注意监测Lp(a)并加强控制Lp(a)水平,控制Lp(a)水平可能对预防二尖瓣环钙化及其相关二尖瓣疾病的发生具有潜在意义。Objective This investigation delineates the potential correlation between serum Lipoprotein(a)[Lp(a)]levels,mitral annular calcification(MAC),and associated mitral valve dysfunction.Methods A retrospective analysis was conducted on the clinical data of 131 patients admitted to the Department of Cardiology at People' s Hospital of Bozhou for coronary CT angiography(CTA)from January 2022 to November 2023.Based on image analysis,patients were divided into the MAC group(62 cases)and the normal group(69 cases).Comprehensive data collection encom-passed demographic information(age,gender),medical history(hypertension,diabetes),and a spectrum of biochemi-cal parameters including high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),Apolipoprotein A,Apolipoprotein B,Serum Lipoprotein(a),Creatinine,Uric Acid,Homocysteine,and history of statin use.The basic clinical data of the two groups were compared,focusing on the differences in the occurrence of mitral ste-nosis and regurgitation.The study also analyzed the risk factors for MAC and the risk of MAC-related mitral valve disea-ses.Results Significant differences were observed in the levels of LDL-C and Lp(a)between the MAC and the control group(P<0.01).Logistic regression analysis identified Lp(a)as an independent risk factor for MAC(OR=1.256,95%CI:1.002-1.490,P=0.008).Lp(a)levels significantly differed between the normal group and both severe MAC and mild-to-moderate MAC groups(P<0.05).The incidence of mitral stenosis did not differ significantly between the groups[8.06%(5/62)in the MAC group vs.1.45%(1/69)in controls,P=0.165].However,mitral regurgitation was significantly more prevalent in the MAC group[17.74%(11/62)in the MAC group vs.4.35%(3/69)in controls,P=0.013].Conclusion Elevated Lp(a)levels are significant risk factors for mitral annular calcification.The pres-ence of MAC may increase the risk of mitral regurgitation.Monitoring and controlling Lp(a)levels in patients with MAC is crucial for preventing MAC progression and associa
