年欧洲心脏病学会(ESC)年会

背景

直接血管成形术是DTEMI最佳的再灌注治疗策略。实行这一手术通常需要发展区域STEMI救治系统。

目的

入选具备介入条件的二级医院的ACS患者,分析区域STEMI救治系统植入前后患者的临床特点及1年的临床预后有无变化。

方法

入选所有连续的ACS患者,其中启动STEMI救治系统前2年内的患者718例,启动STEMI救治系统后1年内的患者293例。通过GRACE评分将患者分为低危组(<108分)、中危组(109-140分)和高危组(>140分)。

结果

全部1011例患者的平均年龄为69.0±12.8岁,两个时间段的患者在平均年龄及危险因素方面无显著性差异。启动STEMI救治系统后的患者既往有冠心病病史的比例更低(20.5% vs. 36.3%; p<0.01),但STEMI的比例更高(42.0% vs. 28.6%; p<0.01)、平均GRACE评分更高(140.1±40.9 vs. 128.1±34.6; p<0.01)。STEMI患者接受直接血管成形术的比例从18.3%上升至91.9%(p<0.01),任何ACS患者血运重建的比例都在增加(71.4% to 88.4%; p<0.01),溶栓结合早期血管成形术(27.4%的STEMI患者)在启动STEMI救治系统后完全消失。两个时间段的平均住院时间(6.5±5.1 vs 5.9±4.9天; p=0.11)及院内死亡率(5.2% vs. 3.8%; p=0.34)无统计学差异,但启动STEMI救治系统后中危(4.3% vs. 0.0%; p=0.04)及高危(40.0% vs. 21.4%; p=0.02)GRACE评分患者的比例明显降低。两个时间段的1年死亡率无显著性差异(7.2% vs. 6.7%; p=0.80),即使对不同GRACE评分危险组进行的亚组分析亦是如此。两组出院时双联抗血小板治疗的比例无差别(78.9% vs. 83.0%; p=0.15),但启动STEMI救治系统后的患者氯吡格雷的使用率下降(81.6% vs. 45.4%; p<0.01),替格瑞洛(0% vs. 20.2%; p<0.01)及普拉格雷(0% vs. 22.3%; p<0.01)的使用率上升。两组在他汀治疗(93.4% vs. 93.6%; p=0.90)及其他治疗方面无差别。

结论

区域STEMI救治系统的植入增加了患者入院的复杂程度,但可降低中高危患者的院内死亡率。尽管血运重建率及新型抗血小板药物的使用率增加,但1年的死亡率仍无差别。
