Evaluation of the door-to-needle time in patients undergoing fibrinolytic therapy after acute myocardial infarction.
Pak J Physiol Jan ;5(2):38-9.

Background: Early thrombolysis with fibrinolytic therapy has reduced mortality following acute myocardial infarction (AMI) with the major effect coming from early achievement of infarct-related artery patency. This study was carried out to determine the door-to-needle time in patients undergoing fibrinolytic therapy after acute myocardial infarction and to identify factors associated with a prolonged door-to-needle time. Methods: This was a cross sectional study in which patients who were thrombolysed for AMI with streptokinase at Punjab Institute of Cardiology, Lahore, from December 12, 2008 to February 18, 2009 were included. All patients admitted with AMI, who were candidates for fibrinolysis, were included. The time of infarction and time of arrival in hospital was determined with ECG changes and asking from patient and/or relatives. The reasons for delay of arrival were asked from patient and accompanying attendants where possible. Results: A door-to-needle time of <30 min could be achieved in 110 of our 201 patients (54.72%). Mean door-to-needle time was 55.13 (±71.04) minutes. Conclusions: A door-to-needle time of less than 30 minutes in 54.72% is comparable to most contemporary studies however there is a need to look into factors associated with delay.
