“…Intensywne uprawianie sportu, zwłaszcza wytrzymałościowego (> 1500 h uprawiania sportów wytrzymałościowych) [899], zwiększa ryzyko AF w późniejszym okresie życia [900][901][902], co prawdopodobnie zależy od zmian napięcia układu autonomicznego, obciążenia objętościo-wego podczas wysiłku, przerostu przedsionka, a także jego powiększenia [903,904]. Prowadzi to do zależności między aktywnością fizyczną a zapadalnością na AF, która ma kształt krzywej U [214,898,902,905,906]. Zmniejszenie obciążeń treningowych może ograniczać występowanie AF w modelach [904] i zmniejsza komorowe zaburzenia rytmu u sportowców [907], ale rola takiego postępowania w odniesieniu do występowania AF u sportowców jest nieznana.…”

“…The race recruits both elite and recreational skiers. Among these skiers, a faster finishing time and a high number of completed races are associated with a future higher incidence of AF5 that may theoretically increase the risk for embolic stroke. Yet, in contrast, the participants in the Vasaloppet have a substantially lower mortality rate compared with the general population 7.…”

BackgroundPhysical activity is of benefit for primary prevention of cardiovascular diseases, but it appears to increase the risk for atrial fibrillation. We aimed to study a cohort of patients following a first stroke in individuals with previous high physical activity, compare them to the general population with respect to recurrent stroke and death, and relate these to atrial fibrillation.Methods and ResultsFrom the participants of the Vasaloppet, the world's largest ski‐race, and matched individuals from the general population (n=708 604), we identified 5964 patients hospitalized with a first‐time stroke between 1994 and 2010. Individuals with severe diseases were excluded. One half percent of skiers and 1% of nonskiers were hospitalized due to stroke. The incidence rate was 8.3 per 100 person‐years among skiers and 11.1 among nonskiers. The hazard ratio (HR) for recurrent stroke or death between the 2 groups was 0.76 (95% CI 0.67 to 0.86). The result was consistent in subgroups. The HR for death was 0.66 (95% CI 0.56 to 0.78) and for recurrent stroke 0.82 (95% CI 0.70 to 0.96). After adjustment for smoking and socioeconomic factors, the HR for death was consistent at 0.70 (95% CI 0.56 to 0.87) while the HR for recurrent stroke was not statistically significant. Outcomes for skiers with atrial fibrillation tended to show a lower risk than for nonskiers.ConclusionsThis large cohort study supports the hypothesis that patients with a stroke and with prior regular physical activity have a lower risk of death, while their risk for recurrent stroke is similar to that of nonskiers. The skiers had a higher incidence of atrial fibrillation, but still no increased risk of recurring stroke.

Atrial fibrillation (AF) is a possible complication of sport in middle-aged athletes. When sinus rhythm has been restored, at what time is deformation restored too? This question has never been answered. We studied an one 47-year old cyclist and runner with acute lone atrial fibrillation. A day before, he trained hard intervals and felt at the next day an irregular rhythm, training was not possible. He told this would occure 2 times a year , but after the light training the irregular puls will disappear. At the chest-pain unit we performed echocardiography inclusive strain measurements of the right and left ventricle during atrial fibrillation and immediately after the recovery of the sinus rhythm. He recovered to sinus rhythm during the exercise test. Global strain was at the moment of atrial fibrillation -11.8%, direct after the recovery of the sinus rhythm -17,2%, and -20.5% at the next day, even though the normalized diastolic function directly after conversion from AF. It seems to be that the heterogenity of the deformation need time to recovery after the conversion to the sinus rhythm, even though the diastolic function seems to be normalized. The further endurance training should be continued only after normalization of deformation values.
