116 4.8 ± 0.6 mm/m2 respectively (P M/C = 0.011, P A/C = 0.024)]. M and C athletes featured larger left-ventricular cavity size compared to A athletes [LVIDd indexed at 28.8 ± 2.9 mm/m2 and 28.9 ± 2.4 mm/m2 (P M/C = 0.887) versus 26.4 ± 2.5 mm/m2 respectively (P M/A = 0.011, P C/A = 0.013)]. Conclusion Morphologic Left-Ventricular (LV) remodeling in mixed-race adolescent athletes is characterized by a greater LV cavity enlargement compared to A athletes and a significant increase in LV wall thickness compared to C athletes. ‘Afro-Caribbean repolarization’ is occasionally seen among these athletes.

[email protected] (M. Ben Abdesslem) Background and aims Sparse data exists to characterize the disease prevalence in athletic patients with complete and incomplete right bundle branch block: (CRBBB) and (IRBBB) respectively. We sought to determine this prevalence in a local sport medical centre. Methods We analysed ECG of athletes on-going a routine and mandatory medical examination in our local sport medical centre. All participants had 2 months of regular activity for at least 4 hours a week (h/w) prior to inclusion. Median follow-up period was 18 months. Results Five hundred and forty-eight athletes were enrolled in the study. History, physical examination and a 12 lead standard ECG was performed for all the participants. Demographic and baseline information for the study participants are exposed in Table 1. BBBD pattern was found in 77 (14%) participants, only one had CRBBB. IRBBB prevalence was 13.86% and CRBBB 0.1%. The athlete with CRBBB had not associated electrocardiographic anomalies suggesting Brugada syndrome or arrythmogenic right ventricle cardiomyopathy. He had a normal Treadmill stress test. His echocardiogram showed mild right ventricle dilatation and was allowed to continue his activity. No events were noticed in this population subset. Conclusion RBBB is not rare in athlete’s community. IRBBB is more common and considered benign. CRBBB is more rare and needs further work-up.

[email protected] (N. Mouine) Introduction Cardiac rehabilitation consists of measures that allow patients to recover their functional capacity through physical exercise and secondary prevention measures. The aim of our study was to evaluate the impact of cardiac rehabilitation in French women compared to men. Materials and methods It’s a retrospective study included 1700 patients admitted in cardiac rehabilitation centre of Léopold-Bellan hospital, Paris, France. All of them had clinical examination, an electrocardiogram, echocardiography, biological test and Ergospirometry. Results We included 439 women (group 1) and 1261men (group 2). The average age of patients was 62.8 ± 12.1 years in group 1 and 63.1 ± 12.4 years in group 2, they had more than three cardiovascular risk factors, hypertension and dyslipidemia was more frequent in women, they were overweight with an BMI at 28.9 ± 7.9 kg/m2 in group 1 and 26.2 ± 7.3 kg/m2 in group 2, clinical examination was normal. Transthoracic Echocardiography showed preserved Left-Ventricular ejection fraction (52.6 ± 12.9% in group 1 and 53.3 ± 12.4% in group 2). After 20 sessions of cardiac rehabilitation, patients showed lower BMI, especially in women (26.4 ± 5.3 kg/m2 ),a significant improvement in the maximal work load, from 68.2 ± 25.6 to 91.2 ± 35.2 watt (P = 0.01) in women and from 90.43 ± 34.1 to 110.37 ± 40.7 watts in men, a significant improvement in VO2max, from 17.1 ± 3.6 to 21.5 ± 6.3 mL/kg/min (P = 0.01) in women and from 20.5 ± 5.1 to 23.2 ± 6.9 mL/kg/min (P = 0.02) in men. Conclusion This study demonstrates that cardiac rehabilitation is benefit for both men and women, to improve their exercise capacity and reduce their cardio vascular risk factors especially in women.
