目的探讨红细胞分布宽度(RDW)与急性心肌梗死患者冠状动脉侧支循环(CCC)形成的关系。方法急性心肌梗死患者124例分为CCC不良组(Rentrop 0~1级,66例)和CCC良好组(Rentrop 2~3级,58例),分析RDW等相关指标与CCC形成的关系。结果 CCC良好组RDW低于CCC不良组[(12.75±1.34)%vs.(13.34±1.15)%](P<0.05);CCC良好组血尿酸浓度低于CCC不良组[(316.90±101.17)μmol/L vs.(353.55±102.94)μmol/L](P<0.05)。CCC良好组有吸烟史比例低于CCC不良组(46.55%vs.65.15%)(P<0.05)。Logistic回归分析显示,高RDW是CCC形成不良的独立危险因素[OR=1.511,95%CI(1.111~2.055),P<0.01]。结论急性心肌梗死患者高RDW与CCC形成不良密切相关。
Objective To investigate the relationship between RDW and coronary collateral circulation (CCC) in patients with acute myocardial infarction. Methods A total of 124 patients with acute myocardial infarction (AMC) were divided into three groups: Renal failure (grade 0 ~ 1, n = 66) and Rentrop grade 2 ~ 3 (n = 58). The relationship between RDW and CCC was analyzed. Results The RDW in the CCC good group was significantly lower than that in the CCC poor group [(12.75 ± 1.34)% vs (13.34 ± 1.15)%] (P <0.05) / L vs. (353.55 ± 102.94) μmol / L] (P <0.05). The rate of smoking in CCC good group was lower than that in CCC poor group (46.55% vs.65.15%) (P <0.05). Logistic regression analysis showed that high RDW was an independent risk factor for poor CCC formation (OR = 1.511, 95% CI 1.111-2.05%, P <0.01). Conclusion The high RDW in acute myocardial infarction patients is closely related to the poor formation of CCC.
