探讨心脏超声的相关参数对房颤射频消融(RAOAF)术后再发中的评估价值.[方法]选择2016年2月至2018年1月在本院诊治的66例RAOAF患者,依据术后是否复发分为复发组(观察组)和未复发组(对照组),比较两组心脏超声的相关参数,Cox回归分析RAOAF术后再发房颤的影响因素.[结果]66例患者有32例患者复发,占48.48%.观察组左房大小、二尖瓣瓣环收缩期收缩峰值速度(s')显著大于对照组,二尖瓣瓣环舒张晚期峰值速度(A'),舒张早期峰值速度(E')显著小于对照组,其差异均有统计学意义(P0.05).多因素Cox回归分析显示:A'是RAOAF术后再发的独立预测因子.[结论]心脏超声的相关参数中A'对RAOAF术后再发的评估有一定的参考价值,值得临床重视.“,”Tostudythevalueofcardiacultrasonography-relatedparametersintheevaluationofrecurrenceaf-terradiofrequencyablationofatrialfibrillation(RAOAF).[Methods]Atotalof66patientswithRAOAFwhoweretreatedin ourhospitalfromFebruary2016toJanuary2018wereenrolledintherecurrencegroup(observationgroup)andthenon-recur-rentgroup(controlgroup).Coxregressionanalysiswereperformedtorevealtheinfluencingfactorsofrecurrentatrialfibrilla-tionafterRAOAF.[Results]Ofthe66patients,32hadrecurrence,accountingfor48.48%.Theleftatrialsizeandsystolic peakvelocityofthemitralannulus(s')intheobservationgroupweresignificantlygreaterthanthoseofthecontrolgroup, whilethepeakvelocityofthemitralannulusatlatediastolicphase(A'),andthepeakofearlydiastolicvelocity(E')weresig-nificantlysmallerthanthoseofthecontrolgroup.Thedifferenceswerestatisticallysignificant(P0.05).MultivariateCoxregressionanalysis showedthatA'peakvaluewasanindependentriskfactorofrecurrenceafterRAOAF.[Conclusion]Amongtheparametersre-latedtocardiacultrasound,A'peakvaluehascertainreferencevaluefortheevaluationofpostoperativerecurrenceofRAOAF, andisworthyofspecialattention.
