摘要
目的:观察不稳定型心绞痛(UAP)患者经皮冠状动脉介入治疗(PCI)后早期并发症的发生情况,检测术前同型半胱氨酸(Hcy)水平及PCI前、术后v WF、白细胞介素-8(IL-8)、一氧化碳(NO)水平,探讨Hcy与PCI早期并发症的关系及可能的作用机制。方法:选择88例行PCI UAP患者,分别于术前、术后30min、4h、12h、24h、48h、72h、7d取外周静脉血,采用酶联免疫吸附双抗夹心法测定Hcy、v WF、IL-8,利用硝酸还原酶法测定NO。结果:88例患者PCI术后心脏早期并发症总发生率为12·5%。早期并发症组患者术前Hcy、v WF和IL-8水平显著高于非早期并发症组(均P<0·05),NO水平显著低于非早期并发症组(P<0·05)。早期并发症组患者术后v WF和IL-8峰值水平显著高于无早期并发症组(均P<0·05),术后NO最低值低于非早期并发症组,但两者相比差异无统计学意义(P>0·05)。Hcy水平与v WF、IL-8术前、术后峰值水平呈正相关(r=0·634,P<0·01;r=0·534,P<0·01;r=0·597,P<0·01;r=0·544,P<0·01),与NO术前、术后低值水平呈负相关(r=-0·568,P<0·01、r=-0·148,P>0·05)。多变量Logistic回归分析,术前Hcy水平(RR=1·225,CI=1·059-1·418,P<0·01),糖尿病(RR=1·712,CI=1·128-2·898,P<0·05)是PCI早期并发症的独立预测因子。结论:①Hcy水平与PCI术后早期并发症密切相关,随着Hcy水平升高,早期并发症有显著增高趋势。②血浆Hcy可能通过影响IL-8、v WF水平导致早期并发症的出现。③Hcy水平对PCI术后早期并发症具有独立预测价值。
Objective:This study aims to investigate the predictive value of homocysteine for early complication in UAP patients with PCI. Method:The study population consisted of 88 patients who underwent PCI. Peripheral blood samples were taken before and 30 min, 4 h, 12 h, 24 h, 48 h, 72 h, 7 d after PCI. Hcy,vWF, and IL-8 were assayed with Enzyme-linked Immunometric Assay, NO was analyzed with Nitrate Reductase Assay. Result: Incidence of early complications in this group of patients is 12.5M. Before PCI, the levels of Hcy, IL-8, vWF were significantly higher in patients with early complications than those without early complications ( P 〈0.05), the level of NO was lower in patients with early complications than those without early complications ( P 〈0. 05). Hcy levels were positively correlated with IL-8 and vWF, but negatively correlated with NO. Levels of Hcy and diabetes were the independent predictors of early complications after PCI ( RR = 1. 225, CI = 1. 059-1. 418, P 0.01, RR =1. 712, CI 1. 128-2. 898, P 〈0.05). Conclusion:①Hcy is related to early complications of PCI. The higher levels of Hcy were, the higher incidence of early complications ②Hcy perhaps influences levels of IL-8 and vWF and contributes to early complications. ③Preprocedural levels of Hcy are powerful independent predic tors of early complications.
