Factors Influencing Pre-hospital Patient Delay in Patients with Acute Myocardial Infarction

Acute myocardial infarction(AMI)is a dangerous disease with a high mortality rate.For AMI patients,the outcome of the patients depends on time to beginning of effective treatment in addition to other factors such as severity of disease and involved vessels etc.The key is whether reperfusion therapy is started early enough after the onset of symptoms,and the benefit of reperfusion therapy depends on the time,too.The delay of AMI treatment is divided into pre-hospital delay and in-hospital delay.In-hospital delay,Door-to-Balloon Time,has been well controlled.Pre-hospital delay,accounting for 75% of the total delay time,is the most important factor affecting AMI treatment.Patient delay(PD)time for AMI patients is summarised in this study.
