Outcomes of percutaneous coronary intervention in a private hospital in Nigeria.

Abstract

Objective: There is sparse information on the outcomes of percutaneous coronary intervention (PCI) in Nigeria. This study examines the outcomes of PCI in a private hospital in Lagos, Nigeria.

Methods: This retrospective study included all patients who underwent coronary angiography and PCI between March 2017 and March 2022. Analysis of variance was used to examine the difference between means across the coronary angiography group. An independent sample t-test was used to analyse the difference across the means in the acute coronary syndrome (ACS) subcategories. Group comparisons were made using the chi-squared test for the non-sparse categorical data.

Results: The number of coronary angiography procedures performed over five years was 317. Most coronary angiography patients were male (73.9%) and Nigerian (78.6%). Ninety patients were diagnosed with ACS, 69 patients had PCI, and 18 patients were referred for coronary artery bypass grafting (CABG). Drug-eluting stents were used exclusively and radial access was utilised on 49.3% of the PCI patients. The average length of hospital stay for the PCI patients was 1.5 days. All patients were placed on dual antiplatelet therapy (DAPT) on discharge and most patients (73.8%) were placed on DAPT, statin, and a beta-blocker. The in-hospital mortality was 7.25% in high-risk patients with complex medical comorbidities and patients with no alternate revascularisation options.

Conclusions: This five-year single-site experience shows the potential of interventional cardiology care in Nigeria. There needs to be continued process improvement to ensure access to the standard of care for coronary artery disease in Nigeria.
