ABSTRACT
Aim: The purpose of this study is to assess the effect of the COVID-19 pandemic on the volume of ST-elevation myocardial infarction (STEMI) patients and also to assess changes in patient characteristics, door-in-to-door-out (DIDO) time, door-to-balloon time (D2B) time, and STEMI outcomes during the pandemic. Methods: Patient data were retrieved retrospectively from the electronic medical record system of King Hamad University Hospital and Mohammed Bin Khalifa Cardiac Centre in the Kingdom of Bahrain. Data were compared and analyzed for the two time periods: before the pandemic (January 2019-March 2020) and during the pandemic (April 2020June 2021). Results: There was a decline of 11.1% in patients who presented with STEMI during the pandemic. There were no major differences between the patient demographics and the baseline characteristics during the two study periods. Recommended DIDO time and D2B time could be achieved only for 7.1% and 35.7% of all STEMI cases during the pandemic. However, no significant differences were noted in the 30 days of mortality, reinfarction, cardiogenic shock, hospital length of stay, and return to the hospital within 30 days for the STEMI patients in the two time periods. Conclusions: There was a decline in patients who presented with STEMI during the pandemic. This was also associated with a lower number of STEMI cases achieving the recommended DIDO time and D2B time as compared to the prepandemic period. However, there was no significant difference in the patient outcomes in the two time periods.
