摘要:
目的:探讨川芎嗪预处理对二尖瓣置换术(MVR)后心肌损伤标志物及短期预后的影响。方法:纳入202例接受单纯MVR的患者,通过倾向评分匹配(PSM)分为川芎嗪组(术前72h梯度输注60mg/kg)与对照组(等量生理盐水)。观察术后48h肌钙蛋白I(cTnI)峰值、乳酸脱氢酶(LDH)峰值、ICU停留时间与术后并发症发生率及铁代谢指标,如铁蛋白、谷胱甘肽过氧化物酶(GPx)、超氧化物歧化酶(SOD)的变化。结果:与对照组相比,川芎嗪组术后cTnI峰值显著降低(t=4.32,P<0.001),LDH峰值显著下降(t=3.07,P=0.002)。川芎嗪组的ICU停留时间显著缩短,中位时间为2.1d,而对照组为3.9d(Z=-2.42,P=0.031),并发症总发生率降低53%(χ2=8.21,RR=0.45,95%CI:0.28~0.73)。与对照组比,川芎嗪组铁蛋白术后24h下降12.5%(t=-3.59,P=0.021);GPx上调26%(t=2.14,P=0.008);SOD上调24%(t=2.06,P=0.040)。结论:术前72h川芎嗪预处理可安全、有效地减轻MVR术后心肌损伤,改善短期预后。
Abstract:
Objective: To investigate the effects of ligustrazine pretreatment on myocardial injury markers and short-term prognosis after mitral valve replacement(MVR). Methods: A total of 202 patients undergoing isolated mitral valve replacement were enrolled and divided into ligustrazine group(receiving 60 mg/kg gradient infusion 72 hours preoperatively) and control group(receiving an equivalent volume of normal saline) via propensity score matching(PSM). The study assessed the peak cardiac troponin I(cTnI) levels,peak lactate dehydrogenase(LDH) levels at 48 hours postoperatively, intensive care unit(ICU) stay duration, postoperative complication rates, and changes in iron metabolism indicators such as ferritin, glutathione peroxidase(GPx), and superoxide dismu-tase(SOD) to explore the potential underlying mechanisms. Results: The ligustrazine group exhibited a significantly lower peak postoperative cTnI level than the control group(t=4.32, P<0.001), along with a significant reduction in peak LDH(t=3.07, P=0.002). The ICU stay was significantly shorter in the ligustrazine group, with a median duration of 2.1 days versus 3.9 days in the control group(Z=-2.42, P=0.031), and the overall complication rate was reduced by 53%(χ2=8.21, RR=0.45, 95% CI: 0.28-0.73). Mechanistic studies revealed that ligustrazine exerts its cardioprotective effects by suppressing ferritin expression(12.5% decrease at 24 h postoperatively, t=-3.59, P=0.021) and enhancing antioxidant enzyme activity(26% upregulation of GPx, t=2.14, P=0.008;24% upregulation of SOD, t=2.06, P=0.040). Conclusion: Preoperative 72-hour ligustrazine pretreatment safely and effectively reduces myocardial injury after MVR and improves short-term prognosis.
