Abstract

Background: Cardiac-related incidents are a public health concern for tactical occupations, and cardiovascular disease rates are higher in these populations compared with civilians. Research is needed to examine blood pressure (BP) responses in firefighters. The pager alert is one occupational hazard, and it is unknown if lifestyle change can reduce the systolic surge response.

Purpose: To measure BP surge with alarm in firefighters to determine whether the magnitude is lower after a 6-week tactical exercise and Mediterranean-diet intervention.

Methods: SBP and DBP and BP surge levels, circulating markers, vascular health, and fitness were analyzed. BP surge with alarm was captured during a 12-hour workshift. Exercise and diet were self-reported. Diet was tracked with diet scores based on number of servings.

Results: Twenty five firefighters (43.4 ± 13.9 years) participated. We found changes in the magnitude of BP surge with alarm (SBP surge from16.7 ± 12.9 to 10.5 ± 11.7 mmHg, P < 0.05; DBP surge from 8.2 ± 10.8 to 4.9 ± 5.6 mmHg, P > 0.05) after intervention. We confirm that clinical (127.6 ± 9.1 to 120 ± 8.2 mmHg) and central (122.7 ± 11.3 to 118.2 ± 10.7 mmHg) SBP levels improve with exercise and diet. We report for the first time in firefighters that oxidative stress markers superoxide dismutase (9.1 ± 1.5 to 11.2 ± 2.2 U/ml) and nitric oxide (40.4 ± 7 to 48.9 ± 16.9 μmol/l) levels improve with an exercise and diet intervention.

Conclusion: These findings have implications toward the benefit that short-term lifestyle changes make toward reducing the alarm stress response in first responders.

在对消防员进行运动和饮食干预后，报警时血压骤升的情况有所缓解。

背景：与心脏相关的事故是战术职业的公共卫生问题，与平民相比，这些人群的心血管疾病发病率更高。需要对消防员的血压（BP）反应进行研究。呼机警报是一种职业危害，而改变生活方式是否能降低收缩压骤升反应尚不得而知。目的：测量消防员在警报时的血压骤升情况，以确定在进行为期 6 周的战术锻炼和地中海饮食干预后，血压骤升的幅度是否会降低：方法：分析 SBP 和 DBP 以及血压激增水平、循环标志物、血管健康和体能。在 12 小时的轮班工作中，捕捉带有警报的血压激增。运动和饮食均为自我报告。根据饮食份数对饮食进行跟踪评分：结果：25 名消防员（43.4 ± 13.9 岁）参加了这项研究。我们发现，干预后，报警时血压骤升的幅度发生了变化（SBP 从 16.7 ± 12.9 mmHg 骤升至 10.5 ± 11.7 mmHg，P < 0.05；DBP 从 8.2 ± 10.8 mmHg 骤升至 4.9 ± 5.6 mmHg，P > 0.05）。我们证实，通过运动和饮食，临床（127.6 ± 9.1 到 120 ± 8.2 mmHg）和中心（122.7 ± 11.3 到 118.2 ± 10.7 mmHg）SBP 水平得到改善。我们首次在消防员中发现，氧化应激标志物超氧化物歧化酶（9.1 ± 1.5 至 11.2 ± 2.2 U/ml）和一氧化氮（40.4 ± 7 至 48.9 ± 16.9 μmol/l）水平在运动和饮食干预后有所改善：这些研究结果对短期改变生活方式以减少急救人员的警报应激反应具有重要意义。

期刊介绍： Blood Pressure Monitoring is devoted to original research in blood pressure measurement and blood pressure variability. It includes device technology, analytical methodology of blood pressure over time and its variability, clinical trials - including, but not limited to, pharmacology - involving blood pressure monitoring, blood pressure reactivity, patient evaluation, and outcomes and effectiveness research. This innovative journal contains papers dealing with all aspects of manual, automated, and ambulatory monitoring. Basic and clinical science papers are considered although the emphasis is on clinical medicine. Submitted articles undergo a preliminary review by the editor. Some articles may be returned to authors without further consideration. Those being considered for publication will undergo further assessment and peer-review by the editors and those invited to do so from a reviewer pool.
