慢性心房颤动对扩张性心肌病患者长期预后的影响

探讨慢性心房颤动 (简称房颤 )对扩张性心肌病患者长期预后的影响。将扩张性心肌病并心力衰竭 (简称心衰 )患者分为窦性心律 (简称窦律 )组 (共 38例 ,其中男 2 5例、女 1 3例 )和房颤组 (共 37例 ,其中男 2 5例、女 1 2例 ) ,二组基础状态基本相似。房颤组只控制心室率。随访二组患者的临床预后情况 ,包括 :死亡人数 ,死亡原因 ,入选至死亡的生存时间。结果 :经过 4 8.3± 2 5 .0月随访 ,发现二组患者远期生存率相似 ,死亡患者生存时间相似 ,死亡方式相似 ;与窦律组相比 ,房颤组左房内径较大 (5 3.1± 5 .6mmvs4 7.1± 4 .8mm)、最快心室率较快 (1 6 2 .8± 1 9.3vs1 1 7.2± 1 6 .9) ,二组差异有显著性 (P <0 .0 5 )。结论 :慢性房颤对扩张性心肌病的远期预后可能无明显影响

Prognositic Value of Chronic Atrial Fibrillation in Dilated Cardiomyopathy Patients With Chronic Heart Failure

To explore the prognostic value of chronic atrial fibrillation in dilated cardiomyopathy patients with chronic heart failure,75 patients were divided into sinus rhythm(SR) group(38 patients,male 25,female 13) and atrial fibrilltion (AF) group(37 patients,male 25,female 12),and they were similar at basic state.AF group was on rate control therapy without anticoagulation. The clinical outcomes were followed up,including death number,death causes,and survival duration.Results:After a period of 48.3±25.0 months follow up,there were no difference between the two group in terms of survival rate,death cause and survival duration,and only left atrium diameter(53.1±5.6 mm vs 47.1±4.8 mm) and HRmax (162.8±19.3 bpm vs 117.2±16.9 bpm) were bigger in AF group than SR group(P<0.05).Conclusion:Chronic atrial fibrillation could not influence the long term outcome of dilated myopathy patients.
