Cedars-Sinai 研究：美国消防员值勤死亡逾四成源于心脏原因、比例逐年上升
位于加州洛杉矶县的 Cedars-Sinai 医疗中心 10 月 21 日发布一项研究：研究团队复盘美国消防管理局记录的 3,401 例消防员值勤死亡案例（1990–2025 年），发现心脏原因占 43%，是值勤死亡的首要类别。研究发表于《JACC: Advances》。
研究对 1990 至 2019 年（疫情前）数据的分析显示，单例值勤死亡为心脏原因的几率每年上升 2.2%，而同期普通人群的心脏死亡几率每年下降 1.3%。研究指出，除冠心病外，越来越多死亡与心肌增厚相关，这类风险可能被常规运动负荷试验漏检。
该研究资深作者、Smidt Heart Institute 心内科助理教授 Alan Kwan 表示，消防员的职业暴露与作息特点使其心脏风险有别于普通人群，需要更有针对性的筛查。Cedars-Sinai 心内科主任 Susan Cheng 亦就研究意义发表了看法。研究全文以期刊发表版本为准。
Cedars-Sinai Study: Cardiac Causes Account for 43% of U.S. Firefighter Line-of-Duty Deaths, and the Share Is Rising
Cedars-Sinai in Los Angeles, California, released a study on October 21 reviewing 3,401 firefighter line-of-duty deaths recorded by the U.S. Fire Administration (1990–2025). Cardiac causes accounted for 43 percent of the deaths, the largest single category. The study was published in JACC: Advances.
Analyzing pre-pandemic data from 1990 to 2019, the researchers found that the odds of a line-of-duty death being cardiac rose 2.2 percent per year, even as cardiac mortality odds in the general population fell 1.3 percent per year. Beyond coronary artery disease, more deaths were linked to thickened heart muscle, a risk that standard exercise stress tests may miss, the study said.
Senior author Alan Kwan, an assistant professor of cardiology at the Smidt Heart Institute, said firefighters' occupational exposures and work patterns make their cardiac risk distinct from the general public's and call for more targeted screening. Susan Cheng, chair of cardiology at Cedars-Sinai, also commented on the findings.
