Episode notes
Fewer Deaths Among Marathon Runners
- Sudden cardiac arrests in marathon runners occur at similar rates now compared to 2000-2009, but mortality rates have decreased.
- Improved survival is linked to better awareness and widespread use of automated defibrillators and CPR teaching.
Screen and Manage Runner Risks
- Screen runners for coronary artery disease if they have risk factors before starting intense exercise.
- Control risk factors like cholesterol to improve safe marathon participation.
Oral Semaglutide Effective for Diabetes
- Oral semaglutide effectively reduces major cardiovascular events in type 2 diabetes patients with cardiovascular or kidney disease.
- This confirms benefits similar to injectable forms with better tolerance due to oral administration.
