目的 探讨缺血后处理对老年急性ST段抬高型心肌梗死(STEMI)患者再灌注损伤的保护作用。 方法 连续选择发病12h内行直接经皮冠状动脉介入治疗(PCI)的急性STEMI患者215例,数字抽签法随机分为缺血后处理组和常规治疗组(对照组),两组年龄65岁及以上患者分别为38例和46例。对照组给予单纯再灌注治疗,缺血后处理组采用再灌注30 s,再缺血30 s,交替3次后再持续灌注的方法。分别评估缺血后处理对老年患者再灌注心律失常的发生率、冠状动急性心肌梗死溶栓试验(TIMI)血流分级和心肌组织水平灌注等指标的影响。 结果 缺血后处理组和对照组再灌注心律失常发生率分别为21.1%(8/38)和45.7%(21/46),差异有统计学意义(x2=5.571,P<0.05);其中高危、需要药物或电转复及临时起搏等干预的心律失常发生率分别为7.9%(3/38)和26.1%(12/46),差异有统计学意义(x2=4.695,P<0.05)。校正的TIMI血流帧数(cTFC)分别为(23.6±3.7)帧和(26.1±5.9)帧(t=5.434,P<0.05)。TIMI心肌灌注分级(TMPG)3级分别为89.5%(34例)和69.6%(32例),差异有统计学意义(x2=4.899,P<0.05)。 结论 心肌缺血后处理能减轻老年STEMI患者心肌再灌注损伤,可应用于老年人STEMI再灌注损伤的防治。
目的 探討缺血後處理對老年急性ST段抬高型心肌梗死(STEMI)患者再灌註損傷的保護作用。 方法 連續選擇髮病12h內行直接經皮冠狀動脈介入治療(PCI)的急性STEMI患者215例,數字抽籤法隨機分為缺血後處理組和常規治療組(對照組),兩組年齡65歲及以上患者分彆為38例和46例。對照組給予單純再灌註治療,缺血後處理組採用再灌註30 s,再缺血30 s,交替3次後再持續灌註的方法。分彆評估缺血後處理對老年患者再灌註心律失常的髮生率、冠狀動急性心肌梗死溶栓試驗(TIMI)血流分級和心肌組織水平灌註等指標的影響。 結果 缺血後處理組和對照組再灌註心律失常髮生率分彆為21.1%(8/38)和45.7%(21/46),差異有統計學意義(x2=5.571,P<0.05);其中高危、需要藥物或電轉複及臨時起搏等榦預的心律失常髮生率分彆為7.9%(3/38)和26.1%(12/46),差異有統計學意義(x2=4.695,P<0.05)。校正的TIMI血流幀數(cTFC)分彆為(23.6±3.7)幀和(26.1±5.9)幀(t=5.434,P<0.05)。TIMI心肌灌註分級(TMPG)3級分彆為89.5%(34例)和69.6%(32例),差異有統計學意義(x2=4.899,P<0.05)。 結論 心肌缺血後處理能減輕老年STEMI患者心肌再灌註損傷,可應用于老年人STEMI再灌註損傷的防治。

Objective To study the cardioprotective effects of ischemic post-conditioning on elderly patients with ST-elevation acute myocardial infarction (STEM1).Methods Consecutive 215 patients with STEMI undergoing emergency percutaneous coronary intervention(PCI) were randomly assigned to receive ischemic post-conditioning or conventional PCI treatment. The ischemic postconditioning (n=38) were conducted by 3 episodes of 30-second occlusion followed by 30-second reperfusion, while the control group (n= 46) was without any intervention after PCI. Reperfusion arrhythmias, corrected TIMI frame count (cTFC) and TIMI myocardial perfusion grade (TMPG)were compared between the two groups, respectively.Results The incidence of reperfusion arrythmias was less frequent in ischemic postconditioning group (21.1% ,8/38) than in control group (45.7% ,21/46) after PCI (x2 = 5.571, P<0.05). The TIMI grade 3 flow was similar between two groups [(94.7%(36/38) vs. 82.6%( 38/46), x2= 2.919, P>0.05], the cTFC levels (23.6±3.7vs. 26.1 ±5.9) and TMPG 3 perfusion [ 89.5% (34/38) vs. 69.6% (32/46)] were significantly different (t= 5.434, P<0.05; x2 = 4.899, P<0.05, respectively) between two groups.Conclusions Ischemic postconditioning may reduce myocardial reperfusion injury in elderly patients with STEMI undergoing emergent PCI.
