Arrhythmogenic right ventricular dysplasia and sudden cardiac death in Croatians' young athletes in 25 years

The paper deals with the sudden cardiac death during training in male athletes in Croatia. The data are a part of a retrospective study dealing with 67 sudden death due to physical activity in men in Croatia during 25 years: from January 1, 1986 to December 31, 2010. Two of them suddenly died during training due to malignant ventricular arrhythmia because of the arrhythmogenic right ventricular dysplasia. First was a short trails runner aged 24, with no any previous physical discomforts, who suddenly collapsed and died during training. The second was a soccer player aged 13, with no any previous physical discomfort, who suddenly collapsed and died during training. A sudden cardiac death due to physical exercise in young athletes in Croatia suffered of arrhythmogenic right ventricular dysplasia reached 0.07/ 100.000 yearly (p = 0.00000), in all young athletes suffered of heart diseases reached 0.19/100 000 (p = 0.00005), and in the total male population aged 15-40 engaged in sports and recreational physical exercise: 0.71/100.0000 (p = 0.00001).
