Abstract：Objective To investigate the correlation between platelet distribution width (PDW) and severity and prognosis of patients with acute myocardial infarction (AMI).Methods A total of 297 AMI patients were selected in our hospital from June 2015 to June 2016.According to the PDW level,they were divided into low PDW group (less than 17％) and high PDW group (PDW ＞ 17％),with 144 cases and 153 cases,respectively.Comparing the two groups of patients with hypertension,hyperlipidemia,diabetes,heart rate,serum creatinine and other basic information,Killip classification,congestive heart failure,cardiogenic shock and death within 1 years or the incidence of re infarction,in-hospital mortality and mortality within 1 year.Results The high PDW group of the proportion of smoking history and grade Killip Ⅳ patients,congestive heart failure,cardiogenic shock,death or reinfarction within one year were higher than low PDW group (x2 =9.12,4.73,5.79,5.24,16.41,20.57;P ＜0.05);the mortality rate during hospitalization was significantly higher than that in low PDW group (P ＜ 0.05);the incidence of chest pain in Killip Ⅱ group was significantly lower than that in low PDW group (t =7.28,x2 =4.25;P ＜ 0.05).Conclusion There is a significant positive correlation with AMI in patients with PDW disease severity,while patients with PDW increased,suggesting an increased risk of 1-year mortality and a higher incidence of re-infarction.Therefore,it helps to guide clinical treatment and improve the prognosis of patients with AMI.
