Primary PCI in the management of STEMI in sub-Saharan Africa: insights from Abidjan Heart Institute catheterisation laboratory.

Background: Implementation of primary percutaneous coronary intervention (PCI) in sub-Saharan Africa remains a challenging issue. The aim of this study was to report the results of primary PCI and outcomes in the catheterisation laboratory of the Abidjan Heart Institute.

Methods: Between April 2010 and March 2019, all patients aged 18 years presenting to the Abidjan Heart Institute for ST-segment elevation myocardial infarction (STEMI) over the study period and who underwent primary PCI were included. We considered primary PCI when it was performed within 48 hours of the onset of symptoms. Baseline data, PCI characteristics and outcomes were analysed.

Results: Among a total of 780 patients hospitalised for STEMI, 471 were admitted within 48 hours of the onset of symptoms. One-hundred and sixty six patients underwent primary PCI, with a ratio of primary PCI/STEMI of up to 21.3%. One hundred and six patients (63.9%) were admitted within 12 hours of the onset of symptoms. The femoral approach was the most commonly used (78.3%). Primary PCI was performed with stent implantation in 84.3% of patients. Drug-eluting stents (DES) were used in 42.1% of patients. In most cases, angiographic success was observed (157/166, 94.6%). Non-fatal complications were mainly haematomas (3.6%). Peri-procedural mortality rate was 1.2%.

Conclusions: Primary PCI can be performed safely in some small-volume centres in sub-Saharan Africa. Healthcare policies and regional networks must be encouraged in order to improve management of STEMI patients.
