beta-Methyl-p-[(123)I]-iodophenyl-pentadecanoic acid (BMIPP) imaging has been used extensively to detect coronary artery disease (CAD), primarily in Japan. However, the reported sensitivity and specificity vary considerably from study to study. This meta-analysis was conducted to summarize the evidence for the diagnostic accuracy of resting BMIPP imaging in the detection of CAD.
A MEDLINE search of the literature published through the end of 2006 was performed. Seven studies (528 patients) met the inclusion criteria. Using random-effects models, the overall sensitivity and specificity to detect CAD were 78% (95% confidence interval, 73% to 81%) and 84% (95% confidence interval, 77% to 89%), respectively. A significant threshold effect was identified among studies, which was expected given the between-study variability in study methodology. A summary receiver-operating characteristic curve yielded an asymmetric curve with an area under the curve of 0.91 (SE, 0.020), indicating excellent diagnostic performance.
Imaging with BMIPP at rest exhibits a moderate sensitivity and high specificity to detect CAD in patients with a high prevalence of CAD. Thus, this tracer may be of great value for patients with acute chest pain and those with relative contraindications to exercise or pharmacologic stress myocardial perfusion imaging (MPI).
β-甲基-p-[(123)I]-碘苯基十五烷酸(BMIPP)成像已被广泛用于检测冠状动脉疾病(CAD),主要在日本。然而,报道的敏感性和特异性在不同研究中差异很大。本荟萃分析旨在总结静息BMIPP成像检测CAD诊断准确性的证据。
对截至2006年底发表的文献进行了MEDLINE检索。七项研究(528例患者)符合纳入标准。使用随机效应模型,检测CAD的总体敏感性和特异性分别为78%(95%置信区间,73%至81%)和84%(95%置信区间,77%至89%)。研究之间存在显著的阈值效应,考虑到研究方法的研究间变异性,这是预期的。汇总的受试者工作特征曲线产生了一条不对称曲线,曲线下面积为0.91(标准误,0.020),表明诊断性能优异。
静息状态下使用BMIPP成像对CAD患病率高的患者检测CAD具有中等敏感性和高特异性。因此,这种示踪剂对于急性胸痛患者以及运动或药物负荷心肌灌注成像(MPI)有相对禁忌证的患者可能具有很大价值。
