Vigili del fuoco e malattie cardiovascolari



 
Emergency Duties and Deaths from Heart Disease among Firefighters in the United States 
NEJM, Volume 356:1207-1215

L'ultimo numero del NEJM ospita uno studio epidemiologico di impressionante precisione sull'incidenza di morte per eventi cardiaci nei vigili del fuoco negli USA su un periodo di circa 11 anni.
Il totale delle morti per cause cardiovascolari rappresenta il 45% delle morti nei firefighters USA, e l'incidenza degli eventi nelle operazioni di soccorso o nelle emergenze è straordinariamante alta e legata probabilmente anche
a concause quali le alte temperature o l'abbigliamento speciale molto pesante oltre allo stress emotivo. In situazioni di emergenza gli eventi cardiaci appaiono essere fino a 100 volte più frequenti. Si conclude suggerendo uno stretto e aggressivo monitoraggio dei fattori di rischio in questa popolazione.

Firefighting Duties Pose Substantial Cardiovascular Risk  

The sudden stress of firefighting poses a significant risk for cardiovascular death, according to an 11-year study in today's New England Journal of Medicine.

Using a national database, the authors estimated time typically spent in different firefighter duties, then estimated expected cardiovascular deaths during each. They measured actual cardiovascular deaths in firefighting centers serving communities of various sizes.

Although fire suppression accounted for only between 1% and 5% of firefighters' professional time, a third of all deaths from coronary artery disease in this population occurred during this activity -- 10 to 100 times as high as the risk associated with nonemergency duties. The risk was also increased during alarm response and return and physical training.

Editorialists conclude that in this population "modifiable risk factors, whether or not they are related to occupation, should be aggressively addressed."
