Abstract
目的探讨二尖瓣环钙化(MAC)与冠心病之间关系,明确MAC能否作为冠心病的独立预测因子.方法对128例年龄≤65岁MAC患者和86例对照者进行冠状动脉造影和超声心动图检查.结果①与对照组比较,MAC组冠状动脉造影阳性率显著增高(88.28%对65.12%,P=0.000),且更容易发生左冠状动脉主干狭窄(15.63%对4.65%,P=0.013)和三支冠状动脉狭窄(55.47%对32.56%,P=0.001);②MAC是冠心病的独立预测因子(P=0.008),其预测价值高于冠心病传统的预测因子高脂血症(P=0.02)、胸痛(P=0.03)和年龄(P=0.04);③MAC对冠心病的阳性预测值为88.28%.结论MAC与冠心病之间存在十分密切的关系,能够作为冠状动脉造影检查的术前筛选指标,提高冠状动脉造影检查的阳性率.
