ABSTRACT
INTRODUCTION: Percutaneous coronary intervention (PCI) remains a major therapeutic tool in the management of acute coronary syndromes (ACS). However, it is not widely practiced in sub-Saharan Africa, particularly for the management of ACS. The availability of a catheterization laboratory for 24-hour management of ACS in Dakar is an important step in improving the prognosis of patients. The objective of our study was to evaluate the clinical and prognostic profile of patients presenting an ACS and treated by PCI. PATIENTS AND METHODS: This is a retrospective study that included all patients who underwent PCI for ACS at hospital principal Dakar during the period from January 2019 to December 2020. RESULTS: Our study included 112 patients with a mean age of 60 years (extremes 31-96 years) and a male predominance (sex ratio 4.09). Cardiovascular risk factors were dominated by hypertension (47.3%) and smoking (39.3%). Chest pain was present in 97% of patients. Left ventricular systolic function was impaired in 56 patients with a mean of 50% and extremes of 20 and 78%. Thrombolysis with streptokinase was used in 13 patients with STEMI. The majority of coronary angiogram (95%) were performed between 8 am and 5 pm. The radial route was the most commonly used (85.7%). Double vessel coronary artery disease was predominant (39,3%) and the left anterior descending artery was the most affected (60.7%). The PCI was performed in all patients and in more than half of the cases (55%) within 12 hours of delay. The PCI success rate was 96.4%. Sixty-seven patients (59.8%) underwent balloon predilation. PCI was performed with a drug-eluting stent in the majority of patients (92.8%). The outcome was favorable in 96.4% of the patients, but there were 3 deaths (2.7%). CONCLUSION: Treatment of ACS by PCI is a reality in Senegal with a considerable success rate. However, intervention delays remain one of the major challenges of this management.
