[The athlete's heart: an echocardiographic case-control study on Senegalese athletes]. / Coeur du sportif: étude échocardiographique cas-témoins portant sur des sportifs sénégalais.

The aim of this work is to study the echocardiographic parameters of male trained athletes. It is about a case-control study comparing 3 groups: basketball players, cyclists and not sports healthy subjects. All the subjects benefited from an echocardiography (time motion, two-dimensional and pulse Doppler). The mean age is of 23.5 years for the cyclists group, 24 years for the basketball players and of 26.2 years for the control group. Compared with the control group, the left ventricular telediastolic dimensions, left ventricular mass index and the pulmonary flow velocity are higher in athletes group. The basketball players have a higher left ventricular diameter and parameter of systolic function than cyclists group. The septal diameter is higher in the cyclists group. This study finds some differencies in Senegalese athletes in the characteristics of the standard athletic heart syndrome.
