摘要(Abstract):
目的评价非ST段抬高急性冠状动脉综合征(acute coronary syndrome,ACS)患者早期应用紧急经皮冠状动脉介入治疗(PCI)的临床疗效。方法2000年1月至2005年9月我院收治的385例中、高危非ST段抬高ACS患者,根据药物治疗后病情变化,分别在入院1~2 d内(233例,紧急介入组)或3~14 d(152例,延迟介入组)行冠状动脉造影(CAG)及PCI。所有“罪犯”病变均予治疗,介入方法有经皮冠状动脉腔内成形术(PTCA)+支架、直接置入支架等。观察两组手术成功率、心绞痛缓解时间、住院时间和PCI后30 d及6个月心源性死亡、心绞痛复发等不良心脏事件发生率。结果紧急介入组手术成功率与延迟介入组相似,分别为98.1%和95.5%(P>0.05),但入院至心绞痛缓解时间分别为(2.9±1.1)d和(6.0±3.6)d(P<0.05);住院时间分别为(9.7±4.3)d和(14.2±6.6)d(P<0.05);在住院期间,两组患者均无急性心肌梗死、猝死及心功能恶化发生。30 d随访期间紧急介入组总不良心脏事件发生率较延迟介入组明显减少,二者分别为2.9%和14.1%(P<0.01)。结论在条件具备的介入中心,由经验丰富和技术娴熟的介入治疗医生施行或在其指导下,对非ST段抬高ACS患者进行早期紧急介入治疗是积极、有效的治疗措施,近、远期临床效果较满意,手术成功率及安全性较高,可作为大多数非ST段抬高ACS患者的首选治疗策略。
