Canadian fans take their hockey seriously — so much so, it appears, that heart attack rates increase the day after a game.

Researchers looked at data on heart attack admissions to a Montreal hospital from June 2010 to December 2014. There were 2,199 admissions, or an average of 1.3 per day, about a quarter of them in women.

Then they checked data on admissions for each day after the Montreal Canadiens played. On the day after a game, admissions for men increased to 1.9 a day from 1.0, while women’s numbers remained the same. The study is in the Canadian Journal of Cardiology.

In the whole population, there was a 15 percent increase in admissions on the day after the team won, but none after a loss. Men under 55 were particularly susceptible, with an increased risk of 40 percent on days after a victory, and 20 percent after a defeat.

The senior author, Dr. Hung Q. Ly, a cardiologist at the Montreal Heart Institute, said that drinking, eating junk food and the excitement of competition can all stress the heart, but the study is observational and he made no assertions about causation.

“I don’t want to scare people away from being hockey fans,” said Dr. Ly, himself an enthusiastic Canadiens fan, “but people should be mindful of what they do, and not assume they’re protected because they’re young.”
