  • Research Finds Firefighters at and Increased Risk of Heart Attack

Researchers find out that firefighters are at a greater risk of heart attack due to exposure to higher temperature

Firefighting is considered one of the most dangerous professions in the world. Men and women risk their lives everyday to save other people’s lives at the risk of their own. Firefighters are always considered with a sense of nobility and pride.

The reason that this job is considered so dangerous is obvious. The risk to their lives is heavy as they run into burning buildings to save other people’s lives. There are burns, smoke inhalation and other injury related risks of the job.

There has been a discovery of one more though. In a recent research conducted in Scotland, UK, researchers studied 19 healthy, nonsmoking firefighters. The under study firefighters were made to take part in two fire simulation exercises which were one week apart in time.

During these fire stimulations, they rescued a "victim," weighing more than 170 pounds, from a two-storey structure while they were exposed to temperatures above 752°F (400°C).

The blood pressures of the sample firefighters were recorded 30 minutes before and 24 hours after the stimulations along with the assessment of their heart rate, heart rhythm, and the strength and timing of electrical impulses passing through each part of the heart.

Lead author Nicholas Mills, Ph.D. explained that they wanted to observe if there was any evidence of heart strain that might signify a lack of blood being delivered to the heart muscle, according to BBC.

He said that harsh conditions that these firefighter face can cause injury to the heart muscle in healthy firefighters and may explain the link between fire suppression and risk of heart attack.

Researchers found that the blood clotting among firefighter under study resulted due to strenuous exertion and exposure to higher temperature. There was also indication of low blood pressure due to dehydration caused by higher temperature.

It thus proved that the firefighters are at a greater health risk to get heart attacks. The researchers suggested that the firefighters should observe healthier lifestyle and work on strengthening their cardiac muscles.
