Randomized controlled trials or observational studies showed that the use of public-access automated external defibrillator (AED) was effective for patients with out-of-hospital cardiac arrest (OHCA). However, it is unclear whether public-access AED use is effective for all patients with OHCA irrespective of first documented rhythm. We aimed to evaluate the effect of public-access AED use for OHCA patients considering first documented rhythm (shockable or non-shockable) in public locations. ⋯ Public-access AED pad application was associated with better outcome among patients with OHCA of medical origin in public locations irrespective of first documented rhythm.

To assess the relationship between heart rate response and exercise tolerance in adults with systemic right ventricle (sRV) after atrial switch repair for Transposition of the Great Artery (TGA) in addition to other physiological parameters. ⋯ Exercise limitation is related to the inability to increase cardiac output during exercise and is notably due to the degree of chronotropic incompetence.

Admission blood glucose (BG) has demonstrated contradictory association with 30-day mortality in acute heart failure (AHF) hospitalization. To explore these contradictory findings, we aimed to determine if admission BG reflects an acute change from chronic glucose control and investigate the association between the admission and chronic BG change (ΔBG) with 30-day mortality in AHF. ⋯ Admission BG predominantly reflects chronic glycemic status. Increased change in admission from chronic BG was associated with increased 30-day mortality.
