THURSDAY, Oct. 8, 2020 (American Heart Association News) — Heart attack risk increases quickly after a flu-like illness, while stroke risk rises slower, according to new research.
The study, published Oct. 8 in the Journal of the American Heart Association, examined the relationship between the flu, heart attacks and strokes, which all occur more frequently during winter months.
Researchers looked at New York state public health data from 2004 to 2015 and focused on adults who were hospitalized or came to the emergency department for stroke, heart attack or “flu-like illnesses.” Study author Amelia Boehme said pinpointing people with the flu from administrative records is difficult. Instead, her study relied on an algorithm developed by the U.S. Centers for Disease Control and Prevention to identify influenza and influenza-like symptoms through billing codes.
The study found that strokes and heart attacks increase during times of high flu-like illness rates,
