Background: Chest pain is among the most common reasons patients visit the emergency department (ED). Any new onset of chest pain or any change in the pattern, intensity, or duration of pain in patients with preexisting symptoms must be evaluated to rule out acute coronary syndrome (ACS). Materials and Methods: This study was conducted at the ED of a 250-bed tertiary care center in North India. All patients presenting to the ED with acute chest pain were evaluated using a strictly protocolized approach. The study lasted from October 1, 2021, to December 31, 2022. Patients diagnosed with ST-segment elevation myocardial infarction (STEMI) were included in the study. Key timelines recorded included the time of patient arrival, time to electrocardiogram (ECG), time to transfer to the cardiac catheterization laboratory (CCL), and time to catheterization in the CCL. Results: A total of 208 patients presenting to the ED with acute chest pain were diagnosed with STEMI. The mean door-to-ECG time was 2.96 min, door-to-CCL time was 35.02 min, and door-to-balloon (DTB) time was 65.36 min. Additionally, 86.1% of patients had a DTB time of |
