背景：值班消防员死亡的主要原因是心源性猝死。虽然原因尚不清楚，但低心肺适能和代谢综合征与心血管疾病相关事件的风险增加有关。目的为了记录心肺适能和代谢综合征的水平，以及确定这些变量之间是否存在关系，方法采用布鲁斯跑步机方案对来自科罗拉多的214名男性消防员进行最大心肺适能评估。作为全面心血管疾病风险评估的一部分，每位消防员还使用国家胆固醇教育计划/成人治疗小组III筛查代谢综合征结果在评估时，32名消防员（15%）符合代谢综合征的NCEP/ATP III诊断标准，54名消防员（25%）未能达到公认的最低心肺适能水平42.0 ml/kg/min。发现心肺适能随着代谢异常的减少而增加的显著相反趋势结论男性消防员心肺适能水平的提高与代谢状况的改善有关。全面的心血管疾病危险因素管理和心肺适能改善对消防员的健康和安全至关重要。
Background The leading cause of mortality in on-duty firefighters is sudden cardiac death. While the reason for this remains unclear, low cardiorespiratory fitness and the metabolic syndrome have been associated with increased risk of cardiovascular disease-related events.Aims To document the levels of cardiorespiratory fitness and the metabolic syndrome, as well as to determine if there is a relationship between these variables, in firefighters.Methods Maximal cardiorespiratory fitness was assessed using the Bruce treadmill protocol in 214 male firefighters from Colorado. As part of a comprehensive cardiovascular disease risk evaluation, each firefighter was also screened for the metabolic syndrome using the National Cholesterol Education Program/Adult Treatment Panel III (NCEP/ATP III) guidelines.Results At the time of their evaluation, 3 2 firefighters (15%) met the NCEP/ATP III diagnostic criteria for the metabolic syndrome, and 54 firefighters (25%) failed to achieve a generally accepted minimum cardiorespiratory fitness level of 42.0 ml/kg/min. A significant inverse trend of increasing cardiorespiratory fitness with decreasing metabolic abnormalities was found (P < 0.001).Conclusions Increased levels of cardiorespiratory fitness are associated with an improved metabolic profile in male firefighters. Comprehensive cardiovascular disease risk factor management and cardiorespiratory fitness improvement are essential for firefighter health and safety.
