HOUSTON (KIAH) — Tis the season for celebration! But stress can be deadly to your heart. Did you know that according to the American Heart Association, more people die from heart attacks during the last week of December than any other time of the year? Doctors say a lot of it has to do with stress. A study published in Circulation, the flagship journal of the American Heart Association, reported that more cardiac deaths occur in the U.S. on December 25 than on any other day of the year, followed by December 26 and January 1. CW39's Sharron Melton talked with interventional cardiologist Dr. David Luke with Vital Heart & Vein about this statistic, in part 1 of 2 interviews talking about this. Then below, check out Part 2 of her interview with Dr. Luke. He talks about signs and symptoms of heart attack and ways to prevent it. The American Heart Association suggests these few tips you should gift yourself and your loved ones as we approach the holiday season: Know symptoms and take action: Heart attack signs vary in men and women and it’s important to recognize them early and call 9-1-1 for help. The sooner medical treatment begins, the better the chances of survival and preventing heart damage. Celebrate in moderation Eating healthfully during the holidays doesn’t have to mean depriving yourself, there are still ways to eat smart. Look for small, healthy changes and swaps you can make so you continue to feel your best while eating and drinking in moderation, and don’t forget to watch your salt intake. Plan for peace on earth and goodwill toward yourself: Make time to take care of yourself during the busy holiday. Reduce stress from family interactions, strained finances, hectic schedules and other stressors prevalent this time of year, including traveling. Keep moving: The American Heart Association recommends at least 150 minutes of physical activity per week and this number usually drops during the hustle and bustle of the holidays. Get creative with ways to stay active, even if it’s going for a family walk or another fun activity you can do with your loved ones.   Stick to your meds: Busy holidays can cause you to skip medications, forgetting them when away from home or not getting refills in a timely manner. Here is a medication chart to help stay on top of it, and be sure to keep tabs on your blood pressure numbers.
