Objectives: Red blood cell microparticles (RBCm) have potential adverse vascular effects and they have been shown to be elevated in ST elevation myocardial infarction (STEMI). The purpose of this study is to investigate their relationship with biochemical infarct size. Methods: RBCm were quantified with flow cytometry in blood drawn from 60 STEMI patients after a primary angioplasty. The creatine kinase-myocardial brain fraction (CK-MB) was measured at predefined time points and the area under the curve (AUC) was calculated. Results: RBCm count was correlated with CK-MB AUC (Spearman's ρ = 0.83, p < 0.001). The CK-MB AUC values per RBCm quartile (lower to upper) were: 3,351 (2,452-3,608), 5,005 (4,450-5,424), 5,903 (4,862-10,594), and 8,406 (6,848-12,782) ng × h/ml, respectively. From lower to upper quartiles, the maximal troponin I values were: 42.2 (23.3-49.3), 49.6 (28.8-54.1), 59.2 (41.4-77.3), and 69.1 (48.0-77.5) ng/ml (p = 0.005). In multivariable analysis, RBCm remained a significant predictor of CK-MB AUC (standardized β = 0.63, adjusted p = 0.001). Conclusions: Erythrocyte microparticles appear to be related to the total myocardial damage biomarker output. The exact pathophysiologic routes, if any, for this interaction remain to be identified. However, these results suggest that erythrocytes may be a - thus far virtually ignored - player in the pathogenesis of ischemic injury.

Objectives: To assess causes of delay for presentation with ST elevation myocardial infarction (STEMI) at our institution. Methods: We included patients with a STEMI that were taken up for primary angioplasty, who had presented from Jan 2017 to December 2019 to the emergency department at Sultan Qaboos university hospital, Muscat. Results: 101 patients (Mean age 54.8+10.8 years; 80 (79.2%) male) were included. The median (IQR) pain to door time was 60 (30-120) minutes.  66 (66%) patients arrived within 90 minutes. All except one arrived by privately arranged transport. Feeling that the pain was not important (60%) or not cardiac (22%) 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. Keywords: Acute myocardial infarction; prehospital delay
