246: Echocardiographic impact of marathon running in 54 female athletes

AimSome recent studies have found a cardiac dysfunction following endurance exercise, but few have examined only feminin athletes. The aim of this study is to estimate the cardiac impact of marathon running in women.MethodsDuring the 2008 edition of the Medoc marathon, 54 female non elite runners (aged 48 ±8 years old) had a medical examination and a cardiac echography just before and after the end of the race.ResultsRunners have finished the marathon in 5h 19±49 minutes. The statistical analysis shows cardiac dysfunction, with a lowering of the ejection fraction (73,5±6 to 69±7% p<0.0005), of the fractional shortening (36±5 to 33±5% p<0.005), changes in the left ventricular loading parameters assessed by the E wave of transmitral filling (85±20 to 67±15cm/s p
