摘要 检测了拟行胸痛综合征评估的零或低冠状动脉钙评分(CS)患者中64层对比增强CT检查所示冠状动脉疾病(CAD)的程度。在连续668例行心脏多层CT的胸痛综合征患者(39%具有急性临床表现,61%具有长期临床表现)中,评定了231例具有零(n=125)或低冠状动脉CS(n=106)的患者(54±12岁,女性占45%)中冠状动脉狭窄(至少1支冠状动脉狭窄〉150%)的患病率和严重程度。231例患者中27例存在阻塞性(〉150%病变)CAD,其中125例零CS患者中有9例(7%),106例低CS患者中有18例(17%),具有急性临床表现的90例患者中有14例(16%),具有长期临床表现的141例患者中有13例(9%)(P值无显著性)。 We examined the extent of coronary artery disease(CAD) on 64-slice contrast-enhanced muhidetector computed tomography in patients who underwent investigation of a chest pain syndrome who had a zero or low coronary calcium score(CS) . In 668 consecutive patients with chest pain syndromes(39% with acute presentation, 61% with long-term presentation) who tector computed tomography, severity of coronary stenoses underwent cardiac muhidewe assessed prevalence and ( ≥ 1 coronary artery stenosis with ≥50% luminal narrowing) in 231 patients(54± 12 years of age, 45% women) with a 0(n = 125) or low(n = 106) coronary CS. Obstructive(≥50% lesion) CAD was present in 27 of 231 patients, in 9 of 125 patients(7% ) with a 0 CS, in 18 of 106(17% ) with a low CS(1 to 100), and in 14 of 90 patients (16%) with an acute presentation and 13 of 141 patients(9% ) with a long-term presentation (p = NS).
