Here’s Why Heavy Snowfall Is Linked To Higher Heart Attack Risk


Did you know that places with heavy snowfall can be associated with high chances of getting heart attacks especially in men? A new research has suggested that people living in the areas with heavy amount of winter snow could be at a greater risk of getting a heart attack after a heavy snowstorm.

Reports state that the heart attack risk was found to particularly higher for men and according to the researchers shovelling is the main reason behind the myocardial infarction (MI) or heart attack, as men tend to shovel the snow to clear ways around their house.

Commenting on the findings of the research, the study co-author Nathalie Auger from University of Montreal Hospital Research Centre in Quebec, Canada said, “Men are potentially more likely than women to shovel, particularly after heavy snowfalls. Snow shovelling is a demanding cardiovascular exercise requiring more than 75 per cent of the maximum heart rate, particularly with heavy loads.”

In order to reach the findings, the team of researchers analysed the data from two separate administrative databases on 128,073 individual hospital admissions and around 68,155 deaths from heart attack (MI) in the province of Quebec between the year 1981 and 2014.

The researchers then restricted their analysis to the months in which snow falls which is November to April and procured a detailed weather information information from Environment Canada for each health region included in the study.

After evaluation, the researchers found out that at least 60 percent of hospital admissions and deaths because of heart attack were in men. The study also made the association of heart attack with a day after heavy snowfall.
“Quantity of snowfall was associated with an increased likelihood of hospital admission or death due to MI the following day among men,” the study said

The findings of the research were published in the Canadian Medical Association Journal.
