Objectives In ST-segment elevation myocardial infarction (STEMI), time delay between symptom onset and treatment is critical to improve outcome. The expected transport delay between patient location and percutaneous coronary intervention (PCI) centre is paramount for choosing the adequate reperfusion therapy. The “Centro” region of Portugal has heterogeneity in PCI assess due to geographical reasons. We aimed to explore time delays between regions using process mining tools. Methods Retrospective observational analysis of patients with STEMI from the Portuguese Registry of Acute Coronary Syndromes. We collected information on geographical area of symptom onset, reperfusion option, and in-hospital mortality. We built a national and a regional patient's flow models by using a process mining methodology based on parallel activity-based log inference algorithm. Results Totally, 8956 patients (75% male, 48% from 51 to 70 years) were included in the national model. Most patients (73%) had primary PCI, with the median time between admission and treatment <120 minutes in every region; “Centro” had the longest delay. In the regional model corresponding to the “Centro” region of Portugal divided by districts, only 61% had primary PCI, with “Guarda” (05:04) and “Castelo Branco” (06:50) showing longer delays between diagnosis and reperfusion than “Coimbra” (01:19). For both models, in-hospital mortality was higher for those without reperfusion therapy compared to PCI and fibrinolysis. Conclusion Process mining tools help to understand referencing networks visually, easily highlighting its inefficiencies and potential needs for improvement. A new PCI centre in the “Centro” region is critical to offer timely first-line treatment to their population.

Background: Regional ST-segment–elevation myocardial infarction (STEMI) networks facilitate timely performance of primary percutaneous coronary intervention (PPCI), reduce mortality and improve outcomes. Few data exist on the feasibility and impact of regional STEMI networks in developing countries. Aim of the Work: The aim of this study was to examine the feasibility and impact of establishing a regional STEMI network on the management and outcomes of STEMI patients in north Cairo. Patients and Methods: A prospective observational study conducted on 352 patients presenting in North Cairo with confirmed diagnosis of STEMI within 48 hours of symptoms. Patients were divided into group I (n = 140) before and group II (n = 212) after establishment of the STEMI network. Both groups were compared as regards patients’ demographics, presentation, management and short-term outcomes. The north Cairo regional STEMI network was established among four governmental hospitals and the governmental ambulance was used for interhospital transfer. WhatsApp® was used for trans-network team communication. Results: Mean age of the study population was 55.4 ± 11.02 years and 286 (81.3%) were males. Mean time from chest pain to first medical contact did not change between the two groups (240 minutes; P = 0.36) while door to balloon mean time was reduced (from 54.3 to 44.1 minutes: P = 0.01). Use of thrombolytic therapy declined from 51 (36.4%) to 16 (7.5%) (P < 0.001) while primary PCI increased from 59.8% to 77.1% (p < 0.001). Left ventricular ejection fraction improved from 51.3 ± 10.7 to 55.4 ± 9.1 (P < 0.001), the mean time of CCU stay was reduced from a mean of 3.0 to 2.0 days (P < 0.001) and in-hospital mortality improved from 6.4% to 2.8% (P = 0.10). Conclusion: The establishment of the STEMI network in north Cairo was feasible and improved patients’ outcomes. Use of primary PCI increased and in-hospital mortality improved from after establishment of STEMI network.
