Kaplan-Meyer of AF recurrences in athletes.
Most (72%) of the athletes resumed vigorous exercise after at least 3
months from the CA, successfully passed preparticipation screening and
could be eligible again for competitive sport activities in agreement
with Italian sport protocols.
Ouctomes in athletes vs non-athletes. After the first year of
follow-up, athletes had a 48% reduced risk of recurrences than NA
[adjusted hazard ratio (HR) on antiarrhythmic drugs, LA volume and AF
subtype, HR 0.52]. These data were confirmed and more significant in
an age-related analysis in which young patients (< 49 years
old) were compared to old patients (> 49 years old) of both
groups. Young athletes had a risk of AF recurrences 4 times lower (HR
3.98) than young NA, while elderly athletes had a 46% reduced risk of
AF recurrences (HR 1.46) than elderly NA. These differences were not
statistically significant due to low sample size, but showed a positive
trend in athletes vs NA (Figure 3 ).
