Episode notes
Daily Steps and Mortality Link
- A large meta-analysis confirms 7,000 daily steps significantly reduce mortality and disease risk.
- However, benefits continue increasing with more steps, suggesting 10,000 remains the optimal goal for health.
Rate vs Rhythm Control in AF
- The AFFIRM trial showed no mortality benefit and a possible trend toward harm with rhythm control over rate control in AF.
- Maintaining anticoagulation and a holistic approach including risk factor modification are key to managing AF effectively.
Caution With GLP-1 Observational Studies
- Beware observational studies on GLP-1 drugs, as confounding often inflates perceived benefits.
- Prioritize randomized controlled trials for reliable evidence on cerebrovascular and neurodegenerative outcomes.
