International audience. AimsImpaired left ventricular–arterial coupling (VAC) has been shown to correlate with worse prognosis in cardiac diseases and heart failure (HF). The extent of the relationship between VAC and circulating biomarkers associated with HF has been scarcely documented. We aimed to explore associations of VAC with proteins involved in HF pathophysiology within a large population-based cohort of middle-aged individuals.Methods and resultsIn the forth visit of the STANISLAS family cohort, involving 1309 participants (mean age 48 ± 14 years; 48% male) from parent and children generations, we analysed the association of 32 HF-related proteins with non-invasively assessed VAC using pulse wave velocity (PWV)/global longitudinal strain (GLS) and arterial elastance (Ea)/ventricular end-systolic elastance (Ees). Among the 32 tested proteins, fatty acid-binding protein adipocyte 4, interleukin-6, growth differentiation factor 15, matrix metalloproteinase (MMP)-1, and MMP-9 and adrenomedullin were positively associated with PWV/GLS whereas transforming growth factor beta receptor type 3, MMP-2 and N-terminal pro-B-type natriuretic peptide (NT-proBNP) were negatively associated. In multivariable models, only MMP-2 and NT-proBNP were significantly and inversely associated with PWV/GLS in the whole population and in the parent generation. Higher levels of NT-proBNP were also negatively associated with Ea/Ees in the whole cohort but this association did not persist in the parent subgroup.ConclusionElevated MMP-2 and NT-proBNP levels correlate with better VAC (lower PWV/GLS), possibly indicating a compensatory cardiovascular response to regulate left ventricular pressure amidst cardiac remodelling and overload.
