中文摘要:

      目的 探讨30 s坐立试验和5次坐立试验对高龄心房颤动(AF)患者心脏康复运动耐量的评估价值。方法 依据欧洲心律协会评分将74例高龄AF患者分为有症状组和无症状组，对比2组6 min步行试验(6MWT)、30 s坐立试验、5次坐立试验、Borg评分等检测结果，采用受试者工作特征(ROC)曲线分析高龄AF患者心脏康复运动耐量评估的效能。结果 无症状组6MWT、5次坐立试验、30 s坐立试验、5次坐立试验Borg气促评分结果明显优于有症状组。ROC曲线分析显示，6MWT、30 s坐立试验、5次坐立试验、30 s坐立试验Borg气促程度评分、5次坐立试验Borg气促程度评分对高龄AF患者有无症状存在预测价值，其曲线下面积分别为0.687、0.666、0.706、0.686。6MWT的临界值为268 m，灵敏度为90.9%，特异度为47.4%; 30 s坐立试验的临界值为5.5次，灵敏度为74.5%，特异度为52.6%; 5次坐立试验的临界值为29 s，灵敏度为69.1%，特异度为68.4%。结论 30 s坐立试验和5次坐立试验或可作为高龄AF患者心脏康复运动耐量的潜在评估工具。

英文摘要:

      Objective To explore the value of the 30-second sit-to-stand test(30 s-STST)and the 5-times sit-to-stand test(5TSTS)in the assessment of exercise tolerance during cardiac rehabilitation in older patients with atrial fibrillation(AF).Methods A total of 74 older AF patients were divided into a symptomatic group and an asymptomatic group according to their European Heart Rhythm Association score.The results of the 6-minute walk test(6MWT),30 s-STST,5TSTS,and Borg score were compared between the two groups.Receiver operator characteristic(ROC)curve analysis was used to evaluate the assessment method for exercise tolerance during cardiac rehabilitation in older AF patients.Results The results of 6MWT,5TSTS,30 s-STST,and Borg dyspnea score during 5TSTS in the asymptomatic group were significantly better than those in the symptomatic group.ROC curve analysis showed that 6MWT,30 s-STST,5TSTS,Borg dyspnea score during 30 s-STST,and Borg dyspnea score during 5TSTS had predictive value for the presence or absence of symptoms in older AF patients,with areas under the curve(AUC)of 0.687,0.666,0.706,and 0.686,respectively.The cutoff value for 6MWT was 268 m,with a sensitivity of 90.9%and a specificity of 47.4%;the cutoff value for 30 s-STST was 5.5 repetitions,with a sensitivity of 74.5%and a specificity of 52.6%;the cutoff value for 5TSTS was29 seconds,with a sensitivity of 69.1%and a specificity of 68.4%.Conclusion The 30 s-STST and 5TSTS may serve as potential assessment methods for exercise tolerance during cardiac rehabilitation in older patients with AF.
