INTRODUCTION-OBJECTIVE: Acute coronary syndromes (ACS) are the leading cause of death among the elderly in sub-Saharan Africa. The aim of this study was to analyze the characteristics of ACS among the elderly at the Abidjan Heart Institute.
MATERIALS AND METHODS: Cross-sectional study from January 1, 2015, to December 31, 2019. All patients aged 18 or more admitted to the Abidjan Heart Institute for ACS were included. These patients were divided into two groups: elderly (≥ 65 years old) and non-elderly (< 65 years old). Clinical data, management and outcomes were compared and analyzed in both groups.
RESULTS: A total of 570 patients were included, of which 137 (24%) were elderly. Sixty percent (60%) of elderly patients presented with ST Segment Elevation Myocardial Infarction (STEMI). Percutaneous coronary intervention (PCI) was less performed among elderly patients (21.1% vs 30.2%, p = 0.039). Heart failure was the most important complication among the elderly group (56.9% vs 44.6%, p = 0.012). In-hospital mortality was 8% among the elderly. Predictive factors for in-hospital mortality were history of hypertension (HR 2.58; CI95% 1.10-6.08) and STEMI presentation (OR 11.60; CI95% 2.70-49.76). PCI was a protective factor for in-hospital mortality (OR 0.14; IC95% 0.03-0.62).
CONCLUSION: ACS occur with increasing frequency with age. Poor outcomes among the elderly are determined by the clinical presentation and comorbidities. PCI appears to significantly reduce in-hospital mortality.
