Abstract 10967: Adaptive Left Ventricular Hypertrophy in Soccer Players: A Five-Year Echocardiographic Follow-up
Background: Regular physical activity determines a progressive increase of the cardiac mass. It is an “Adaptative, Reversible and Physiological”hypertrophy whose Left Ventricle (LV)morphological aspect can be more concentric or eccentric in consequence of the type of sports practiced .No long term data are anyway now available in case of is a mixed training sport like soccer. The aim of the study was to follow up by the echocardiographyc exam, the impact of the physical training on the heart morphology in a group of soccer players for at least five years.
Method: Since January 1993 up to December 2005 a group of 220 athletes ,playing in a Serie A Soccer team ACF Fiorentina, matched with a sedentary control group, were yearly followed by 2D echo-exam. The were regularly trained for 11 months a year, for at least 2 hours for five times in a week and they played a match on the Sunday. In the month of July the players made a stage of 3 weeks of 2 sessions of training including 2-3 hours daily. Among them ,46 athletes had a full 5 years echo-follow up with a complete evaluation of the aortic dimensions at root (AOr), LVDD (left ventricle diastolic diameter), LVSD (Left ventricle systolic diameter), IVS (interventricular septum), PW (posterior wall) thickness and LVMi (Left Ventricular Mass index) and EF %.
Results: In athletes the LV dimensions and the LVMi were significantly higher than sedentary controls (LVMi : 123,45 vs 94,36 gr/m2 respectively). After five years follow up, the athletes didn't show any modifications of the cardiac dimensions : Left Ventricular Diastolic diameter changes slightly from 52.00 ± mm to 52.90 ± mm; Left Ventricular Systolic diameter increased from 31.58 ± mm to 32.33 ± mm, Left Ventricular Mass index from 120.77 to 121.45 gr/m2 ;p=NS) and no significant enhancement of the aortic root diameter was observed (Aortic root: from 27.39 mm to 31.64 mm).
Conclusions: In regularly trained athletes the LV dimensions chamber and LVMi are normally to the upper limits of the normal range. After a five -years -follow-up all the of cardiac chambers dimensions maintains anyway the same size with stable LVM values The regular physical exercise induces a mild LV hypertrophy. This increase of the of the LV chamber can be therefore considered a normal adaptative consequence to stress-
