INSIGHT

AF Is Growing From Age, Risk, And Detection

  • Atrial fibrillation prevalence is rising due to aging, accumulated risk factors, and wearable detection.
  • AF increases hospitalization, stroke risk, mortality, and healthcare costs substantially.
INSIGHT

Three-Part Mechanism Of Atrial Fibrillation

  • AF needs a trigger, a susceptible substrate, and perpetuators for maintenance.
  • Lifestyle risk factors act as perpetuators that remodel the atrial substrate and promote persistence.
ADVICE

Systematically Screen With HEAD-TO

  • Use the HEAD-TO acronym to screen modifiable AF risk factors: heart failure, exercise, arterial hypertension, diabetes, tobacco, obesity, ethanol, sleep apnea.
  • Address each present factor because treating one alone often isn't enough for durable rhythm control.
