Abstract： Background Acute myocardial infarction (AMI) is the leading cause of morbidity and disability among Iranian population.Pre-hospital delay is an important cause of increasing early and also late mortality in AMI.Thus the aim of the present study was to identify the factors influencing pre-hospital delay among patients with AMI in Iran.Methods Between August 2010 and May 2011,a cross-sectional and single-center survey was conducted on 162 consecutive patients with ST-elevation myocardial infarction (STEMI) admitted to Cardiac Care Unit (CCU) of Dr.Heshmat Hospital,Rasht.All patients were interviewed by the third author within 7 days after admission by using a four-part questionnaire including socio-demographic,clinical,situational and cognitive factors.Data were analyzed by descriptive and Logistic regression model at P ＜ 0.05 using SPSS 16.Results Mean age was (60.11±12.29) years in all patients.Majority of patients (65.4％) were male.The median of pre-hospital delay was 2 hours,with a mean delay of 7.4 hours (±16.25 hours).Regression analysis showed that admission in weekend (P ＜0.04,OR=1.033,95％ Cl=1.187-2.006) and misinterpretation of symptoms as cardiac origin (P ＜0.002,OR=1.986,95％ Cl=1.254-3.155) and perceiving symptoms to not be so serious (P ＜0.003,OR=3.264,95％Cl=1.492-7.142) were factors influencing pre-hospital delay ＞ 2 hours.Conclusions Our findings highlight the importance of cognitive factors on decision-making process and pre-hospital delays.Health care providers can educate the public on AMI to enable them recognize the signs and symptoms of AMI correctly and realize the benefits of early treatment.
