Winter viruses can trigger heart attack or stroke, study reveals

If you catch the flu, we found the risk of a heart attack goes up

- 

MELBOURNE: Winter is here, along with cold days and the inevitable seasonal surge in respiratory viruses.

But it's not only the sniffles we need to worry about. Heart attacks and strokes also tend to rise during the winter months.

In new research out this week we show one reason why.

Our study shows catching common respiratory viruses raises your short-term risk of a heart attack or stroke. In other words, common viruses, such as those that cause flu and COVID, can trigger them.

Wait, viruses can trigger heart attacks?

Traditional risk factors such as smoking, high cholesterol, high blood pressure, diabetes, obesity and lack of exercise are the main reasons for heart attacks and strokes.
