[摘 要] 目的:分析心房颤动(atrial fibrillation,AF)伴中度及以上心房功能性二尖瓣反流(atrial functional mitral regurgita⁃
tion,AFMR)患者的临床特征和相关因素。方法:本研究为单中心横断面研究。连续纳入2023年7月—2024年3月入住南京医
科大学附属江宁医院心血管内科的AF伴AFMR患者共313例,根据二尖瓣反流程度分为中度以下AFMR组(A组,249例)与中
度及以上AFMR组(B组,64例)。比较基线资料,采用Logistic回归分析AF伴中度及以上AFMR的相关因素。结果:两组间年
龄、CHA2DS2⁃VASc 评分、房颤类型、肾功能不全病史、射血分数保留的心力衰竭(heart failure with preserved ejection fraction,
HFpEF)病史、氨基末端脑钠肽前体(N⁃terminal pro⁃brain natriuretic peptide,NT⁃proBNP)、三尖瓣反流程度、左房内径、左室舒张
末内径、左室射血分数差异有统计学意义(P < 0.05)。多因素回归分析显示,左房内径(OR=1.067,95%CI:1.002~1.137,P<
0.05)、左室舒张末内径(OR=1.153,95%CI:1.052~1.264,P < 0.05)、三尖瓣轻⁃中度反流(OR=6.571,95%CI:1.362~31.705,P <
0.05)、三尖瓣中度反流(OR=10.795,95%CI:3.816~30.543,P < 0.05)、三尖瓣中⁃重度反流(OR=19.525,95%CI:4.593~82.999,
P < 0.05)、三尖瓣重度反流(OR=20.701,95%CI:5.799~73.896,P < 0.05)是AF伴中度及以上AFMR的独立危险因素。结论:与
AF伴中度以下AFMR患者相比,AF伴中度及以上AFMR患者具有不同的临床特征,通常有更多的临床伴发疾病,左房内径增
大、左室舒张末内径增大和三尖瓣轻度以上反流是AF伴中度及以上AFRM的独立危险因素。

[Abstract] Objective:To investigate the clinical characteristics and identify the associated factors in patients with atrial fibrillation
(AF)and moderate to severe atrial functional mitral regurgitation(AFMR). Methods:This was a single⁃center and cross⁃sectional
study,which recruited a total of 313 patients with AF and AFMR hospitalized in the cardiovascular department of the Affiliated
Jiangning Hospital of Nanjing Medical University from July 2023 to March 2024. Patients were categorized into two groups based on
the severity of mitral regurgitation:the less than moderate AFMR group(Group A,n=249)and the moderate to severe AFMR group
(Group B,n=64). Baseline data were compared,and correlation analysis and logistic regression were employed to determine the factors
associated with moderate to severe AFMR in AF patients. Results:Significant differences(P < 0.05)were observed between the groups
in age,CHA2DS2⁃VASc score,type of atrial fibrillation,history of renal insufficiency,heart failure with preserved ejection fraction
(HFpEF),N⁃terminal pro⁃brain natriuretic peptide(NT⁃proBNP),tricuspid regurgitation severity,left atrial diameter,left ventricular
end diastolic diameter,and left ventricular ejection fraction. Multivariate logistic regression analysis revealed that left atrial diameter
(OR=1.067,95% CI:1.002-1.137,P < 0.05),left ventricular end diastolic diameter(OR=1.153,95% CI:1.052-1.264,P < 0.05),
mild⁃to⁃moderate tricuspid regurgitation(OR=6.571,95% CI:1.362-31.705,P < 0.05),moderate tricuspid regurgitation(OR=10.795,
95%CI:3.816-30.543,P < 0.05),moderate⁃to⁃severe tricuspid regurgitation(OR=19.525,95% CI:4.593-82.999,P < 0.05),and
