Clinical significance of platelet parameters in elderly patients with acute myocardial infarction

Objective To investigate the clinical significance of platelet parameters in elderly acute myocardial infarction (AMI) patients.Methods Apply US Kurt company TT-R1 type blood cells analyzer to determine PLT,MPV and PDW value in 84 elderly patients with AMI(AMI group) and 90 people at the same period(healthy control group) from March 2007 to November 2010,recorded and analyzed these data.Results PLT of AMI group was lower than those of the healthy control groupt(221±62)×10~9/L vs(280±32)×10~9/L],MPV and PDW are higher than those in the healthy control group [(10.30±1.08)fl vs(9.80±0.50)fl and(13.01±2.07)%vs(11.48±0.40)%],the differences have statistical significant (P 0.05 );PLT were negatively correlated with MPV,PDW of AMI group(r = - 0.341,r = - 0.462,P 0.05 ). Conclusion PLT decreased,MPV and PDW were increased,during onset of acute myocardial infarction,activation of platelet is an independent risk factor of AMI.
