Surveying & Assessing Firefighter Fitness & Electrocardiography: The SAFFE Study

描述(申请人提供)：全国有100多万消防员在为地铁、农村社区和野生动物林业提供服务，公众依赖于他们的最佳健康状态。然而，与警察相比，消防员的心血管死亡人数是警察的两倍，是紧急医疗人员的四倍。到目前为止，尽管消防员的心脏风险很高，而且它具有社会重要性，但目前还没有可用的消防活动期间的生理记录来揭示消防员因公殉职的原因。因此，调查和评估消防员体能和心电图的主要目的：SAFFE研究旨在开发一种非侵入性风险分层方法，以更好地识别存在心血管事件风险的消防员。在这项探索性/发展性研究中，118名专业消防员将被招募参与研究方案，研究方案包括(1)基线心电和V02测量，(2)分级运动平板试验中的最大容量心电和V02测量，以及(3)值班心电和VO2测量。连续12导联心电图将在轮班开始时启动，并在消防员的所有活动期间保持24小时，包括：(1)火警呼叫、(2)医疗呼叫、(3)训练、(4)用餐、(5)锻炼和(6)休息/睡眠。在选定的时段内，将在整个班次中获得间歇性的V02措施，包括：火警呼叫、医疗呼叫和培训。在基线、最大容量和值班时，将报告显示特定心电异常和非线性HR/V02关系的消防员的比例。由于心脏事件是主要的死亡原因之一，使用生物测量(ECGs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。与公共卫生相关全国有100多万消防员为地铁、农村社区和野生动物林业提供服务，公众取决于他们的健康状况。然而，与警察相比，消防员的心血管死亡人数是警察的两倍，是紧急医疗人员的四倍。由于心脏事件是主要的死亡原因之一，使用生物测量(ECGs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.
