经皮冠脉介入治疗围手术期心肌损伤影响因素分析

摘要

Objective To investigate influencing factors of perioperative myocardial injury in patients undergone percutaneous coronary intervention (PCI). Methods Ninty one patients with coronary heart disease (including stable angina and unstable angina) underwent PCI, the perioperative myocardial injury incidence were observed prospectively by monitoring the preoperative and postoperative high sensitivity troponin protein levels to investigate the influencing factors of perioperative myocardial injury by Logistic regression analysis. Results There were no statistically significance in perioperative myocardial injury incidence (62.5%vs 68.7%, P=0.618) and perioperative myocardial infarction incidence (29.2%vs 20.9%, P=0.411) between stable angina and unstable angina groups . These factors of perioperative myocardial injury in patients undergone PCI by Logistic regression analysis were analysed, and we found that the influencing factors were the application loading dose rosuvastatin before PCI, preoperative statin therapy more than one month, apolipoprotein A levels and total stent length. Conclusion Application loading dose of rosuvastatin before PCI, preoperative statin therapy more than one month, apolipoprotein A levels are related to perioperative myocardial injury reduction, whereas the total length of the stent is associated with an increased occurrence of perioperative myocardial injury.%目的：探讨经皮冠脉介入治疗（percutaneous coronary intervention， PCI）围手术期心肌损伤影响因素。方法：91例接受择期PCI的冠心病患者（包括稳定型心绞痛和不稳定型心绞痛患者），通过监测术前、术后高敏肌钙蛋白水平，前瞻性观察两组患者围手术期心肌损伤的发生率，应用Logistic回归分析围手术期心肌损伤发生的影响因素。结果：稳定型心绞痛和不稳定型心绞痛两组患者PCI术后围手术期心肌损伤的发生率（62．5％vs 68．7％，P＝0．618）、围手术期心肌梗死的发生率（29．2％vs 20．9％，P＝0．411）没有统计学差异。多因素Logistic回归分析PCI围手术期心肌损伤发生的影响因素，发现PCI术前应用负荷量瑞舒伐他汀治疗、PCI术前他汀治疗超过1个月、载脂蛋白A水平、植入支架总长度是其影响因素。结论：PCI术前应用负荷量瑞舒伐他汀治疗、PCI术前他汀治疗超过1个月、载脂蛋白A水平与围手术期心肌损伤发生率下降有关，而植入支架总长度与围手术期心肌损伤发生率升高相关。
