On Cox regression analysis, only WRF with iTRPG was associated with higher mortality (hazard ratio 4.24, P = 0.001), even after adjustment for other confounders. CONCLUSION An increase in TRPG may provide a marker to identify prognostically relevant WRF in patients with AHF. Published on behalf of the European Society of Cardiology.

Since the European criteria have been recently revised, we aimed at studying prevalence of low muscle strength (LMS) and low muscle mass (LMM), as defined according to the European Working Group of Sarcopenia in Older People (EWGSOP) 2 and 1 definitions, and their individual contribution towards mortality and incident mobility disability in a cohort of community-dwelling older people. METHODS Longitudinal analysis of 535 participants of the InCHIANTI study. LMS and LMM were defined according to criteria indicated in the EWGSOP2 and 1. Cox and log-binomial regressions were used to examine association with mortality and 3-year mobility disability (inability to walk 400m). RESULTS We observed a lower prevalence of the combination LMM/LMS according to EWGSOP2 compared to EWGSOP1 (3.2% vs.6.2%). Using the new criteria, all sarcopenia components were associated with mortality, although the hazard ratio[HR] for the group LMM/LMS was no longer significant after adjustment for confounders (LMM HR 2.69,95% C.I.1.04-6.94; LMS HR 3.18,95% C.I.1.44-7.01; LMM/LMS HR 2.95,95% C.I.0.86-10.16). Using EWGSOP1, LMS alone was independently associated with mortality (HR 4.43,95% C.I.1.85-10.57). None of the sarcopenia components conferred a higher risk of mobility disability. CONCLUSIONS The EWGSOP2 algorithm leads to a r
