ObjectiveTo determine the time from onset of symptoms to start of fibrinolysis and treatment in acute ST elevated myocardial infarction patients and identify the factors which cause delay in treatment.MethodsA cross sectional study was conducted at National Institute of Cardiovascular Diseases, Karachi on 360 conveniently selected patients of ST elevated myocardial infarction from July to September in the year 2017. Structured questionnaire was used to obtain detailed information on socio-demographics, factors which cause delay and timing of onset of symptoms to arrival of patient in emergency ward.ResultsOverall, the total average time from the start of symptoms to initiation of treatment was 119.85+-63.32 minutes.. Only 5.1% patient reached within one hour while 57.7% reached within two hours. Old age group of 60 and above was positively associated with timely arrival (OR=2.75, 95% CI 1.33-5.68, p=0.006). Significant positive association of using personal car as mode of transport to reach the hospital (OR=5.25, 95% CI 2.94-9.35, p<0.001) was also found as compared to using ambulance. Distance from facility was suggestive of negative association in the model but was statistically insignificant.ConclusionAccording to the findings of this study, more than one third of patients reached the hospital within two hours of initiation of symptoms while only 5.1% reached within one hour. The delay was mostly pre-hospital attributed to arranging transport, stay at first medical contact and time taken from first medical contact to the hospital.Copyright: © Pakistan Journal of Medical Sciences.
