目的:研究红细胞分布宽度(RDW)与维吾尔族急性心肌梗死(AMI)患者严重并发症的关系。方法:选取136例维吾尔族AMI患者,按RDW是否>16.0%分组。住院期间,测量左心室射血分数(LVEF),观察Killip分级、严重并发症(包括恶性心律失常、心力衰竭Killip分级2~4级和心源性休克)的发生率和住院心源性死亡率。结果:RDW升高组的严重并发症(心力衰竭、恶性心律失常、心源性休克)发生率及心源性死亡率明显高于RDW正常组(P<0.05),而LVEF显著降低(P<0.05)。结论:维吾尔族AMI患者RDW升高,严重并发症发生率、心源性死亡率高,预后不良。
Objective: To study the relationship between RDW and severe complications in Uygur AMI patients. Methods: 136 Uighur AMI patients were selected and divided into groups according to whether RDW was> 16.0%. During hospitalization, the left ventricular ejection fraction (LVEF) was measured and the incidence of Killip grading, severe complications (including malignant arrhythmia, grade 2 to 4 Killip heart failure and cardiogenic shock) and in-hospital cardiac mortality . Results: The incidence of serious complications (heart failure, malignant arrhythmia, cardiogenic shock) and cardiac mortality in RDW elevated group were significantly higher than those in normal RDW group (P <0.05), while LVEF was significantly lower (P < 0.05). Conclusions: The RDW of Uygur AMI patients is elevated, the incidence of serious complications, high cardiac mortality and poor prognosis.
