Abstract
IntroductionA multidisciplinary therapeutic optimization unit (COT) was created in January 2023 at Versailles Hospital, aimed at therapeutic optimisation of patients with chronic heart failure with reduced left ventricular ejection fraction. The objective of the study was to assess the impact of the first year of COT activity on the sequential implementation and titration of heart failure treatments, the clinical evolution, and improvement of patients’ quality of life. MethodsThis prospective study included consecutive patients treated by the COT after hospitalisation for acute heart failure, from January to December 2023. Clinical, biological, titration, and tolerance data were analysed. Quality of life was assessed at baseline and at the end of the follow-up by COT, using standardized SF-12 and EQ-5D questionnaires. ResultsWe included 90 patients (men 73%, mean age 67 years). The mean left ventricular ejection fraction was 34 ± 10 %. At final visit (median number of visits 4 ; median follow-up duration 156 days), 76.7% of patients achieved optimisation with respect to maximum individually tolerated doses, but only 13.3% with respect to theoretical maximum doses for the four therapeutic classes. At 1-year follow up, total mortality was 4.4% (4/90), and 9 patients (10%) were rehospitalised unplanned for acute heart failure. COT monitoring was associated with significant improvement in NYHA class, left ventricular ejection fraction, and SF-12 and EQ-5D-5L quality of life scores. ConclusionAlthough titration of heart failure treatments remained suboptimal, significant improvement was observed for NYHA class, left ventricular ejection fraction, and patient quality of life parameters.
