Background: Continuous anticoagulation based on the CHA2DS2-VASc score is recommended to prevent embolism caused by atrial fibrillation (AF), but it does not consider AF episodes. The Apple Watch's continuous heart rhythm monitoring and fast-acting direct oral anticoagulants (DOACs) could enable precise, episode-tailored anticoagulation, reducing bleeding risks while preventing stroke. This study evaluates Apple Watch-guided personalized anticoagulation therapy, adjusting DOAC usage based on real-time AF detection.

- Undernutrition has a negative impact on patients with heart failure and preserved ejection fraction (HFpEF), affecting their long-term prognosis after discharge.
- A study categorized 547 HFpEF patients based on their nutritional status at discharge and one year later, identifying those who normalized or worsened in their nutritional scores.
- The findings revealed that worsening nutritional scores increased the risk of all-cause mortality or readmission, while improving scores were linked to better outcomes, with certain predictors identified for changes in nutritional status.
Article Synopsis
- Pareidolias are perceptual deficits where people see meaningful shapes in ambiguous visuals, studied in neurodegenerative diseases using a noise pareidolia test.
- This research explored differences between paper-based and digital testing methods for pareidolias among healthy individuals and patients with Alzheimer's, DLB, and Parkinson's disease.
- Results show that pareidolic perceptions remain consistent in both testing formats, and digital testing on smartphones can effectively maintain the functionality of assessing these visual illusions.
Objectives: N-terminal pro brain natriuretic peptide (NT-proBNP) is a biomarker for myocardial stress that is used in diagnosing and prognosticating heart failure (HF). However, its interpretation is complicated by clinical factors. This study aims to clarify the prognostic value of NT-proBNP in patients with heart failure with preserved ejection fraction (HFpEF), and risk-prediction cutoffs considering various clinical factors.
