A machine learning model for identifying patients at risk for wild-type transthyretin amyloid cardiomyopathy.
Transthyretin amyloid cardiomyopathy, an often-unrecognized cause of heart failure, is now treatable with a transthyretin stabilizer. It is therefore important to identify at-risk patients who can undergo targeted testing for earlier diagnosis and treatment, prior to the development of irreversible heart failure. In this study, the investigators showed that a random forest machine learning model could identify potential wild-type transthyretin amyloid cardiomyopathy using medical claims data.

The prevalence of cognitive impairment among adults with incident heart failure: the "Reasons for Geographic and Racial Differences in Stroke" (REGARDS) study.
The REGARDS study determined the prevalence of cognitive impairment (CI) among adults aged 45 and older with incident heart failure (HF) in order to improve understanding of cognition in HF. Cognitive function was assessed using the Six-Item Screener, and the prevalence of CI among those with incident HF was compared with the prevalence of CI among a matching cohort without HF. The study results indicated that 14.9 percent of the adults with incident HF had CI, suggesting that the majority of cognitive decline occurs after HF diagnosis. The authors suggest that increased awareness of CI among newly diagnosed patients and ways to mitigate it in the context of HF management are warranted.

Numeracy, health literacy, cognition, and 30-day readmissions among patients with heart failure.
Numeracy, health literacy, and cognition are important for chronic disease management. Prior studies have found them to be associated with poorer selfcare and worse clinical outcomes, but limited data exists in the context of heart failure (HF), a condition that requires patients to monitor their weight, fluid intake, and dietary salt, especially in the post hospitalization period. The purpose of this study was to examine the relationship between numeracy, health literacy, and cognition with 30-day readmissions among patients hospitalized for acute decompensated HF (ADHF).
