目的 探讨冠状动脉钙化检测联合动态心电图对冠心病的诊断价值及临床应用。 方法 对2010年5月－2011年8月住院的108例拟诊冠心病的患者同期进行128排螺旋CT冠状动脉钙化积分检测、动态心电图和冠状动脉造影，对比研究冠状动脉钙化检测联合动态心电图预测冠心病的价值。 结果 冠状动脉钙化阳性预测冠心病的灵敏度、特异度、阳性预测值和阴性预测值分别为75.6%、81.0%、73.9%、82.3%；动态心电图阳性预测冠心病的灵敏度、特异度、阳性预测值和阴性预测值分别为73.3%、76.2%、68.8%、80.0%；冠状动脉钙化检测联合动态心电图的系列实验的特异度和阳性预测值分别达到96.8%和92.9%，平行试验的灵敏度和阴性预测值分别达到93.3%和92.7%，均显著高于单项试验的相应指标（P＜0.05）。 结论 高分辨率螺旋CT冠状动脉钙化检测联合动态心电图显著提高冠心病的诊断价值，可作为老年患者及基层医院冠心病首选的筛选检查。
ObjectivesTo systematically review the clinical efficacy of ultrasound-guided percutaneous lavage (UGPL) for calcifying tendinitis of rotator cuff.MethodsPubMed, The Cochrane Library, EMbase, WanFang Data, CBM, VIP and CNKI databases were electronically searched to collect the randomized controlled trials (RCTs) of ultrasound-guided percutaneous irrigation for calcifying tendinitis of rotator cuff from inception to September 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 7 RCTs involving 587 patients were included. The results of meta-analysis showed that: there were significant differences between the UGPL group and extracorporeal shock wave therapy (ESWT) group in 12-month follow-up visual analogue scale (VAS) (MD=–1.96, 95%CI –2.18 to –1.75, P<0.000 01), the average particle size of the calcium deposition (MD=–3.13, 95%CI –5.05 to –1.22,P<0.001), the calcification disappearance rate (RR=1.65, 95%CI 1.36 to 2.01,P<0.000 01). However, there were no significant differences between the two groups in 6-week follow-up VAS (MD=–0.85, 95%CI –2.84 to 1.14,P=0.40), and the complications (RR=1.20, 95%CI 0.03 to 49.69, P=0.93).ConclusionsCurrent evidence shows that UGPL has certain clinical effect for the calcifying tendinitis of rotator cuff. Compared with ESWT, UGPL may be superior in clinical pain relief and calcification clearance. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
