Doctors think the main reason may be stress and a change in our healthy routines.
But there are simple steps we can take for a heart healthy holiday.
As you head to holiday parties, fill up on vegetables. Overeating is often inevitable this time of year, but don't forget the veggies.
And when you reach for the desserts - try not to overdo it. We don't want to overload our system with fat.
Try to keep an eye on the salt. When our sodium levels get too high, this can raise our blood pressure.
And don't drink too much alcohol, this raises the risk for heart rhythm problems and heart attacks. Men should have no more than 2 alcoholic beverages a day and women just one.
If you're trying to quit smoking, if possible, do it before the holidays.
And don't put exercise on the back burner. Fit it in when you can.
If you feel chest pain or other heart attack symptoms, don't worry about spoiling the holiday fun. Get help right away.
