Introduction: The prevalence of in-hospital ACS has risen from 4% to 10% in Dakar cardiology departments over the past 15 years.

Hypothesis: The aim of this study was to describe the epidemiological, clinical profile and short-term prognosis of patients with acute ST Segment Elevation Myocardial Infarction (STEMI) treated by percutaneous coronary intervention (PCI).

Methods: This was a single-center descriptive study using prospective data collection from September 2020 to July 2022, including all patients with acute STEMI managed by PCI in with Hôpital Principal Dakar (HPD). The latter is the main military hospital of Senegal.

Results: Among the 1146 patients admitted in HPD cardiology department, 156 (13.61%) had STEMI and 92 (58.97%) of them had undergone PCI. The mean age of the patients was 60.04 ± 11 years, with a male predominance (78.26%). Eighty-three patients (90.2%) were seen within the first 12 hours, with an average of 3.26 ± 3 hours. Regarding clinical presentation, almost all patients (98.9%) were in Killip I or II class. Seventy-eight patients (84.8%) had a diagnostic ECG within the first 12 hours of symptoms initiation, with a mean of 3.95 ± 2.95 hours. Thrombolysis was performed in 10.86% of the patients with a success rate of 70%. The radial approach predominated largely (89%) and primary PCI was performed in 71.73% of patients. Overall, PCI with stent implantation, exclusively drug eluting stent (DES), was done in 95.65% of cases with a success rate of 98.91%. Three non-fatal periprocedural complications were reported and in-hospital mortality rate was 4.34%.

Conclusions: In Dakar, the prognosis of acute STEMI has been improved since the availability of PCI with routine primary PCI 24/7. However, the intervention delays need to be perfected.
