In heart failure (HF) with reduced ejection fraction, randomized trials of statins did not demonstrate improved outcomes. However, randomized trials may not always be generalizable. The aim was to determine whether statins are associated with improved outcomes in an unselected nationwide population of patients with HF with reduced ejection fraction overall and in relation to ischemic heart disease (IHD). ⋯ In an unselected nationwide population of patients with HF with reduced ejection fraction, statins were associated with improved outcomes, specifically in the presence of IHD. This contrasts with previous randomized controlled trials. Additional randomized controlled trials with more generalized inclusion or focused on IHD may be warranted.

Randomized Controlled Trial
Baseline distribution of participants with depression and impaired quality of life in the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist Trial.
Previous studies have demonstrated the psychosocial effect of heart failure in patients with reduced ejection fraction. However, the effects on patients with preserved ejection fraction have not yet been elucidated. This study aimed to determine the baseline characteristics of participants with heart failure with preserved ejection fraction as it relates to impaired quality of life (QOL) and depression, identify predictors of poor QOL and depression, and determine the correlation between QOL and depression. ⋯ URL: http://www.clinicaltrials.gov. Unique identifier: NCT00094302.

Survival after pediatric cardiac extracorporeal life support (ECLS) is guarded, and neurological morbidity varies widely. Our objective is to report our 10-year experience with cardiac ECLS, including survival and kindergarten entry neurocognitive outcomes; to identify predictors of mortality or adverse neurocognitive outcomes; and to compare 2 eras, before and after 2005. ⋯ Mortality has improved over time; time for lactate to fall on ECLS and volume of platelets transfused are independent predictors of mortality. Extracorporeal cardiopulmonary resuscitation and era were not independently associated with neurocognitive outcomes.

Observational Study
Left atrial remodeling and function in advanced heart failure with preserved or reduced ejection fraction.
Left atrial (LA) structure and function are altered in most heart failure (HF) patients, but there may be fundamental differences in LA properties between HF with preserved (HFpEF) and reduced ejection fraction (HFrEF). ⋯ HFrEF is characterized by greater eccentric LA remodeling, whereas HFpEF by increased LA stiffness, which might contribute to greater atrial fibrillation burden. LA function is associated with pulmonary vascular disease and right HF in both HF phenotypes, but is associated with outcome more closely in HFpEF, supporting efforts to improve LA function in this cohort.
