[Optimization of heart failure treatment in Abidjan heart institute].

Introduction: The aim of the study was to assess the level of treatment optimization after follow-up at discharge.

Methods: We conducted a retrospective study carried out from January 1st, 2016 to December 31st, 2018 in Abidjan Heart Institute with patients hospitalized for heart failure and reviewed in consultation.

Results: The study involved 350 patients with an average age of 53.53 ± 16.38 years (54% were males). The prescription of diuretics (92%) after optimization was at the mean and with maximum doses of 29.1% and 7.7%. ACEIs/ARBs (77.1%) had optimal and mean doses for ACEIs of 14.3% and 29.7%. With beta-blockers (72.6%) there was an improvement in doses at 35.4% for the average doses and 3.1%. for the maximum dose. Spironolactone (44.3%) kept the same average dose at 5.7% The median time of optimization was 287.05 days with a median of 140 days. Only 13.4% of patients were receiving optimal treatment at optimal doses. By logistic regression, the presence of LVEF ≤ 0,40 or LVEF= 0.41-0.49 or global heart failure (P < 0.001) favored drug optimization (OR = 24.68[7.15-82.22], P < 0.001); (OR = 11.39[3.25-39.86], P < 0.001) on the other hand, a high serum creatinine level was an obstacle for treatment optimization (OR = 0.92[0.88-0.96], P < 0.001).

Conclusion: The optimization of the treatment of heart failure is insufficient with too long delays in our context. The optimization time was so long. It could be improved by setting up a clinic to optimize the treatment of heart failure.
