Controversy has evolved over the most practical and effective strategy for preparticipation cardiovascular screening of competitive athletes to detect unsuspected cardiovascular disease and prevent sudden death on the athletic field. Athlete screening in the Veneto region of Italy is part of a national program (with 12-lead electrocardiography) that has reported the detection of previously undiagnosed hypertrophic cardiomyopathy and a decrease in the cardiovascular death rate in young athletes. In this study, over time periods of similar length, cardiovascular-related mortality rates in Veneto athletes were compared with those of a demographically similar region of the United States (Minnesota) in which screening is limited to history and physical examination. There were 55 sudden cardiovascular deaths reported in Veneto over 26 years (2.1/year), compared with 22 deaths in 23 years (0.96/year) in Minnesota. Over the recent and comparable 11-year period, 1993 to 2004, 12 deaths were reported in Veneto and 11 in Minnesota. When analyzed as deaths per 100,000 person-years, Veneto exceeded Minnesota for all years combined (1.87 for 1979 to 2004 vs 1.06 for 1985 to 2007, respectively, p = 0.006), although the 2 regions did not differ significantly for 1993 to 2004 (0.87 vs 0.93, respectively, p = 0.88) or most recently for 2001 to 2004 (0.43 vs 0.90, respectively, p = 0.38). In conclusion, sudden cardiovascular deaths in young competitive athletes occurred at a low rate in both Veneto and Minnesota. Despite different preparticipation screening strategies, athlete sudden death rates in these demographically similar regions of the United States and Italy have not differed significantly in recent years. These data do not support a lower mortality rate associated with preparticipation screening programs involving routine electrocardiography and examinations by specially trained personnel.
对于竞技运动员参与运动前心血管筛查以检测未被怀疑的心血管疾病并预防运动场上猝死的最实用且有效的策略,一直存在争议。意大利威尼托地区的运动员筛查是一项全国性计划(采用12导联心电图)的一部分,该计划报告了此前未被诊断出的肥厚型心肌病的检出情况以及年轻运动员心血管死亡率的下降。在本研究中,在相似时长的时间段内,将威尼托地区运动员的心血管相关死亡率与美国人口统计学特征相似的一个地区(明尼苏达州)进行了比较,在明尼苏达州,筛查仅限于病史和体格检查。威尼托地区在26年中有55例心血管猝死报告(每年2.1例),相比之下,明尼苏达州在23年中有22例死亡(每年0.96例)。在最近可比的11年期间,即1993年至2004年,威尼托地区报告了12例死亡,明尼苏达州报告了11例。按每10万人年的死亡数分析,威尼托地区在整个时间段内超过了明尼苏达州(1979年至2004年分别为1.87例和1985年至2007年的1.06例,p = 0.006),尽管这两个地区在1993年至2004年(分别为0.87例和0.93例,p = 0.88)或最近的2001年至2004年(分别为0.43例和0.90例,p = 0.38)没有显著差异。总之,年轻竞技运动员的心血管猝死在威尼托地区和明尼苏达州的发生率都很低。尽管参与运动前筛查的策略不同,但近年来美国和意大利这些人口统计学特征相似地区的运动员猝死率没有显著差异。这些数据不支持与涉及常规心电图检查和由经过专门培训的人员进行检查的参与运动前筛查计划相关的较低死亡率。
