Cold weather linked to heart attacks

(WJBK) - It is getting colder outside, what does that mean for your risk of a heart attack?

"It is a very powerful study of 275,000 patients," said Dr. Shukri David, cardiology chief, Ascension Michigan. "They were monitored in cold weather and seasonal weather and we noticed there was higher incidents during cold, seasonal weather in (32 degrees or less)."

In the colder weather, arteries go into constriction, David said, leading to heart attacks.
