摘要：

【目的】比较稳定型心绞痛 (SAP)与不稳定型心绞痛 (UAP)患者冠状动脉 (冠脉 )钙化 (CAC)的不同模式。【方法】 6 7例SAP与 94例UAP患者 ,行选择性冠脉造影和电子束CT(EBCT)检查 ,分析两组CAC积分 (CS)的差异及其与冠脉狭窄程度之间的关系。【结果】①SAP组CAC检测阳性率 ( 10 0 % )显著高于UAP组 ( 87 2 3% ) (P <0 0 5 )。②SAP组CAC积分显著高于UAP组 ,其自然对数转换值 [ln (CS + 1) ]的均数按心脏整体计算为 ( 5 2 4± 1 72 )对 ( 3 13± 1 96 ) (P <0 0 0 1) ,按冠脉分支计算为 ( 3 2 8± 2 0 8)对 ( 1 6 8± 1 6 2 ) (P <0 0 0 1)。③在每一相同的年龄段内比较 ,SAP组的CAC程度均明显高于UAP组。④ln (CS + 1)与冠脉狭窄程度在两组均呈正相关 ,但SAP组相关程度相对较好 ;SAP组重度狭窄的冠脉多发生重度或中度钙化 ,而UAP组重度狭窄的冠脉则多数无钙化或仅有轻度钙化。【结论】稳定型与不稳定型心绞痛患者冠脉钙化存在不同的模式 ,前者冠脉钙化大多较为严重 ,钙化积分与冠脉狭窄程度的相关性较好 ,而后者钙化程度多数较轻 ,钙化积分与冠脉狭窄程度的相关性很差
