RESUMEN
Objectives: This study aimed to identify angiographic features that would predict myocardial viability after coronary intervention for ST elevation myocardial infarction (STEMI). Methods: This retrospective study included patients who attended Sultan Qaboos University Hospital, Muscat, Oman, between January and December 2019 with a STEMI. Results: A total of 72 patients (61 male; mean age = 54.9 ± 12.7 years) were included in the study; 11 patients had evidence of non-viability on echocardiography. There were 13 patients with viable myocardium and 3 with non-viable myocardium who had a myocardial blush grade (MBG) of 2 or lower. Similarly, 10 patients with viability and 1 with non-viable myocardium had thrombolysis in myocardial infarction (TIMI) flow of 2 or lower in the infarct related artery (IRA). However, none of these were statistically significant. The TIMI flow in the IRA at the end of the procedure correlated with the MBG. Conclusion: There were no clear angiographic features during primary angioplasty that could predict myocardial viability.

Objectives: To assess the causes of delay for presentation with ST elevation myocardial infarction (STEMI). Methods: Patients who presented with STEMI to the Emergency Department at the Sultan Qaboos University Hospital, Muscat, Oman between January 2017 and December 2019 and were admitted for primary angioplasty were included in this study. Results: A total of 101 patients were included with a mean age of 54.8 + 10.8 years and the majority were male patients (n = 80; 79.2%). The median (interquartile range) pain-to-door time was 60 min (30-120 min). There were 66 (65.4%) patients who arrived within 90 minutes. All except one arrived by privately arranged transport. Feeling that the pain was not important (61.0%) or not cardiac (22.8%) were the main reasons for delay. Being diabetic was the only patient factor that predicted delay. Conclusion: A high proportion of patients presenting to our institution with a STEMI arrived within recommended times. However more public education is required to improve awareness about the importance of early evaluation of chest pain.
