Surveying & Assessing Firefighter Fitness & Electrocardiography: The SAFFE Study

描述（由申请人提供）：全国有超过100万名消防员为地铁、农村社区和野生动物林业服务，公众依赖于他们的最佳健康状态。然而，消防员的心血管死亡人数是警察的两倍，是紧急医疗反应人员的四倍。到目前为止，尽管消防员的心脏风险很高，而且具有社会重要性，但在消防活动期间没有可用的生理记录可以揭示消防员在执勤时死亡的原因。因此，调查和评估消防员健身和心电图的主要目的：SAFFE研究是开发一种非侵入性风险分层方法，以更好地识别有心血管事件风险的消防员。对于这项探索性/发展性研究，将招募118名专业消防员参与研究方案，包括（1）基线ECG和VO 2测量，（2）分级运动平板试验期间的最大容量ECG和VO 2测量和（3）值班ECG和VO 2测量。连续12导联心电图将在轮班开始时启动，并在所有消防员活动期间保持24小时，包括：（1）消防呼叫，（2）医疗呼叫，（3）培训，（4）用餐，（5）锻炼和（6）休息/睡眠。在整个轮班期间，将在选定时段获得间歇性V02测量结果，包括：火警电话、医疗电话和培训。将在基线、最大容量和值班时报告表现出特定ECG异常和非线性HR/V02关系的消防员比例。心脏事件是导致死亡的主要原因之一，使用生物学措施（ECG和V02）来更好地识别为公众服务的高危急救人员，将有助于评估风险和评估优化健康的干预策略。公共卫生相关性该国有超过一百万名消防员为地铁、农村社区和野生动物林业提供服务，公众的健康状况取决于他们的健康状况。然而，消防员的心血管死亡人数是警察的两倍，是紧急医疗反应人员的四倍。心脏事件是导致死亡的主要原因之一，使用生物学措施（ECG和V02）来更好地识别为公众服务的高危急救人员，将有助于评估风险和评估优化健康的干预策略。

DESCRIPTION (provided by applicant): With over a million firefighters in the country servicing metro, rural communities, and wildlife forestry, the public depends on their optimal state of health. However, firefighters have twice as many cardiovascular deaths compared to police officers and four times the proportion among emergency medical responders. To date, despite the high cardiac risk for firefighters and its societal importance, there are no available physiological recordings during firefighting activities that may reveal why firefighters are dying on duty. Thus, the primary aim of the Surveying & Assessing Firefighter Fitness & Electrocardiograms: The SAFFE Study is to develop a non-invasive risk stratification approach to better identify firefighters at risk for cardiovascular events. For this exploratory/developmental study, 118 professional firefighters will be recruited to participate in the research protocol which includes (1) baseline ECG & V02 measures, (2) maximum capacity ECG & V02 during a graded exercise treadmill test and (3) on-duty ECG & VO2 measures. Continuous 12 lead ECG will be initiated at the beginning of the shift and maintained for 24 hours during all firefighter activities including: (1) fire calls, (2) medical calls, (3) training, (4) meals, (5) exercise, and (6) rest/sleep. Intermittent V02 measures will be obtained throughout the shift during select periods including: fire calls, medical calls and training. The proportion of firefighters that demonstrate specific ECG abnormalities and nonlinear HR/V02 relationship will be reported at baseline, maximum capacity and on-duty. With cardiac events as one of the leading causes of death, the use of biological measures (ECGs & V02) to better identify at-risk first responders who service the public, would aid in assessing risk and evaluating intervention strategies that optimize health.
