- AIMS: Impaired 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 RESULTS: In 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 (E a)/ventricular end-systolic elastance (E es). 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 E a/E es in the whole cohort but this association did not persist in the parent subgroup. CONCLUSION: Elevated 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.

- Visit-to-visit office blood pressure (BP) variability (BPV) has been associated with morbidity and mortality outcomes in several cardiovascular conditions. The aim of this study was to evaluate the association between BPV and outcomes in patients with heart failure and reduced ejection fraction and the effect of eplerenone on BPV.We evaluated the associations between BPV, calculated as SBP coefficient of variation (SBP-CoV=SD/mean×100%), and the primary composite endpoint of cardiovascular mortality or heart failure hospitalization (HFH), and its components, in 2549 patients from the Eplerenone in Patients with Systolic Heart Failure and Mild Symptoms trial. Lower SBP-CoV was independently associated with a higher risk of all the studied outcomes, while higher as well as lower SBP-CoV were associated with a higher risk of cardiovascular death. After a median follow-up period of 21 months the risk of the composite outcome of cardiovascular death or HFH was almost double in the lower SBP-CoV tertile as compared with the intermediate tertile [adjusted hazard ratio: 2.01, 95% confidence interval (1.62-2.51), P<0.001]. The relationship between SBP-CoV and outcomes was not modified by eplerenone (P value for interaction=0.48). An interaction was detected between mean SBP and SBP-CoV for the primary outcome (P=0.048) and for HFH (P=0.018). The effect modification was slight, but lower SBP-CoV was associated with worse outcomes in patients with both low and high SBP, while this interaction was less clear for patients with SBP in the 'normal' range.In our patients with heart failure and reduced ejection fraction and mild symptoms, both a lower and higher SBP-CoV were associated with worse outcomes. SBP-CoV did not modify the benefit of eplerenone. Further studies are warranted to clarify the role of BPV in heart failure. CLINICALTRIALS.NCT00232180.
