Assessing delays in primary percutaneous coronary intervention for ST-segment elevation myocardial infarction patients at a tertiary care hospital in Sri Lanka: a retrospective cohort study.

Objectives: To analyse patient profiles, transportation patterns and time delays in ischaemic time and door-to-balloon (DTB) time and evaluate the effect of these delays on in-hospital mortality among patients undergoing primary percutaneous coronary intervention (P-PCI) for ST-segment elevation myocardial infarction (STEMI) at a tertiary care hospital in Colombo.

Design: Retrospective observational study.

Setting: Tertiary care hospital specialising in STEMI treatment, located in Sri Lanka.
