Implication
Identifies potential lone AF risks; hypothesis-generating and requires prospective validation before practice implications.
Structured PICO
Are accumulated lifetime physical activity, height, and left atrial size independent risk factors for lone atrial fibrillation in middle-aged individuals?
P
Population
214 individuals, comprising 107 consecutive patients younger than 65 seen in the emergency room for an episode of lone atrial fibrillation (LAF) of <48 h duration, and 107 healthy volunteers matched for age and sex. Mean age 48 +/- 11 years, 69% male.
I
Intervention
Accumulated lifetime physical activity (moderate and heavy intensity), height, and left atrial size (exposure)
C
Comparator
Healthy volunteers matched for age and sex
O
Outcome
Presence of lone atrial fibrillation
Accumulated lifetime moderate and heavy physical activity, height, and left atrial size are independent risk factors for lone atrial fibrillation in middle-aged individuals.
