摘要 目的探讨不稳定性心绞痛(UA)危险度分层和冠状动脉病变的关系,对比分析能否通过UA危险度分层预测冠状动脉病变程度,以利于治疗方法选择及预后判定。方法按照UA危险度分层标准将212例UA患者作为观察组分为高危、中危、低危3组,比较3组间冠状动脉病变程度。另有52例稳定性心绞痛(SA)作为对照组。根据冠状动脉造影结果,以单支病变、双支病变、三支病变、左主干病变、完全闭塞病变、无显著性病变、冠状动脉积分作为对比指标。结果低危、中危、高危3组之间冠状动脉积分分别为30.2±30.6、39.8±31.1、68.1±43.3,高危组显著高于低危和中危组。三支病变在高危组发生率高,与低危组相对比有显著性差异。单支病变在低危组发生率高,与高危组相差明显。在UA组和SA组,三支病变发生率UA组显著高于SA组。结论UA危险度分层和冠状动脉病变程度相关,高危组三支病变和冠状动脉积分显著增高,提示冠状动脉病变广泛和严重,低危组单支病变显著高提示冠状动脉病变相对简单,此结果对UA患者治疗策略选择有临床意义。
