Heart Attack Triggers

Do You Know About These 8 Surprising Heart Attack Triggers?

Beth Levine

You probably already know many of the factors that increase your risk of a heart attack, which occurs when blood flow to the heart is blocked. These include:

  • A family history of cardiovascular events
  • Obesity
  • Diabetes
  • Stress
  • Lack of exercise
  • Smoking
  • Excessive drinking
  • Uncontrolled high blood pressure and high cholesterol

According to the Centers for Disease Control (CDC), someone has a heart attack every 40 seconds in the United States, which translates to 805,000 people a year. To lessen your risk of becoming part of that statistic and increase your overall wellness, you should pay attention to the well-known stressors. You should also give a thought to other less well-known heart attack triggers that may be surprising to you. Below are the top eight—and what you can do about them.

1. Air Pollution

More than two-thirds of deaths attributed to air pollution are due to cardiovascular events, according to a study published in Free Radical Biology and Medicine. There are several reasons for this, but the most important is oxidative stress, which happens when fine particles in air pollution (especially from exhaust) damage the heart’s defense systems.

Protect Your Heart:

  • Check the Air Quality Index to see when pollution is high: When air quality is bad in your area, minimize your time outside.
  • Take B Vitamins: A Columbia University study shows that this vitamin can reverse the detrimental effect of air pollution on the heart.
  • Reduce your time stuck in traffic: Instead, you can try taking the scenic route to avoid tie-ups.

2. Anxiety, Depression, Stress and Rage

Prolonged stress from uncontrolled negative emotions, like road rage, can pack a wallop on your heart health. According to the American Psychological Association, people with clinical depression have twice the risk of heart attack for up to 10 years after a depressive episode. Another study published in the Journal of Psychosomatic Research found that people with high levels of anxiety and anger are at a higher risk for a heart attack.

Protect Your Heart:

  • Seek help: Look for a trained, accredited psychotherapist who can help you develop coping strategies. If necessary, they may prescribe medication.
  • Practice mindfulness and meditation: A statement published in the Journal of the American Heart Association reported that meditation may reduce your risk of a heart attack. (Search “guided meditation” on YouTube to get started.)
  • Reduce your stressors: If you are feeling overwhelmed by life, divide your responsibilities up by what you must do, what you want to do and what you should do but’s it’s not that important. Get rid of the third one! Then ask yourself what chores you can delegate to someone else.
  • Exercise: No, you don’t have to become a gym rat but get your body moving. A daily walk, yoga session or bike ride. Find what feels good to you. The Mayo Clinic recommends 75 minutes a week of aerobics. They also suggest doing strength training for all muscle groups twice a week for around 12 to 15 repetitions.

3. Skipping Your Flu Shot

The flu is nothing to mess around with. An investigation published in JAMA Cardiology showed that coming down with the flu is significantly associated with heart attacks and heart failure.

Get Your Flu Shot

Protect Your Heart:

Get to a healthcare professional or pharmacist to get your flu shot every year. At most pharmacies, you won’t even need an appointment. In addition, use the same precautions you learned with COVID-19:

  • Wear a mask
  • Stay six feet apart when you are out in public
  • Wash your hands frequently

4. Migraines

People with a history of migraine headaches have an increased risk of a cardiovascular event, according to a study sponsored by the National Heart, Lung and Blood Institute. They also showed a twofold increase in the risk of stroke. Migraines differ from headaches in their intensity. They are often accompanied by nausea, auras and sensitivity to light and sound.

Protect Your Heart:

If you suspect you have migraines, see a doctor right away for diagnosis and a healthcare plan that will include medications that can prevent migraines or give relief during one. Also, learn and avoid your migraine triggers—the most common ones are:

  • Alcohol
  • Stress
  • Bright light
  • Strong smells
  • Sleep disruption
  • A change in barometric pressure
  • Food additives such as monosodium glutamate (MSG)

5. Sleeping Too Little—Or Too Much

Sleep recommendations say to aim for six to nine hours a night. A recent study published in the Journal of American College of Cardiology looked at what happens when you go over or under that amount. Results: People who slept longer than nine hours had a 34% higher risk for heart attack, while people who caught less than six hours of sleep had a 20% higher risk.

Heart Attack Trigger Too Much Sleep

Protect Your Heart:

For Short Sleepers:

  • Establish a firm bedtime routine and stick to it.
  • Make your bedroom a sanctuary—banish all technology that might tempt you to stay up.
  • Don’t use any lighted technology for the hour before bedtime.
  • Don’t drink alcohol in the hours leading up to sleep. Contrary to popular belief, it actually disrupts sleep and causes shorter sleep cycles.
  • Intense exercise right before sleep will just jazz up your system. If you must, gentle yoga stretches can actually promote sleep.

For Long Sleepers:

  • Stick to a strict sleeping schedule, even on weekends.
  • Use a natural light alarm clock. These emit a glow that gets stronger, mimicking the rising sun, which signals to your circadian rhythm that it is time to get going. Some also include gentle wake-up sounds.
  • Check your medications with your prescribing doctors. Some can be very sedating. (Never stop a prescribed drug without first talking with your physician.)
  • If you find that despite all this, you still feel exhausted, see a doctor. There may be an underlying medical reason you’ve lost your get up and go, such as obstructive sleep apnea (when you stop breathing for a moment while sleeping). This in itself is a risk factor for heart attack.

6. Gum Disease

A groundbreaking study published in the Journal of Dental Research found that around 47% of American adults have some level of periodontitis, a serious gum infection. In adults 65 and older, that increases to 70%. So, what has that got to do with your heart? Several studies have shown that there is a link between gum disease and heart disease. Researchers aren’t entirely sure why, but guess that it may have to do with the inflammation.

Protect Your Heart:

  • Prevent gum disease: Brush your teeth (and tongue) after meals, floss, rinse with mouthwash and see a dentist or periodontist regularly.
  • Know your risk: Smoking, age, diet and genetics can all increase your chances. Talk with your dentist or periodontist about how to minimize them.
  • See your dentist at the first signs of gum infection: If your gums are swollen, bright red, tender to the touch, bleed easily, pull away from your teeth or if your teeth feel loose or crooked, they could be infected according to the Mayo Clinic.

7. Cold Weather

When the temperature gets frigid, your heart has to work harder to try to keep your body warm. In addition, your arteries constrict, which limits blood flow to the heart. But don’t worry, you don’t have to move someplace warm to keep your heart healthy.

Stay Warm to Avoid Heart Attack Triggers

Protect Your Heart:

  • Dress warmly in layered clothing: This helps trap the heat inside. Don’t forget a hat and gloves.
  • Wrap a scarf wrapped loosely around your mouth and nose: This allows you to breathe in warmer air.
  • Wear waterproof boots or shoes: This way if you step in a puddle, you won’t have freezing toes or feet after.
  • Use hand warmers and toe warmers: Slip them into your gloves and boots to stay warm in extra cold conditions. You can get disposable or battery-operated ones.
  • Stay hydrated: Bring along a thermos of something hot – cocoa, coffee or tea, for example.
  • Take breaks inside: If you feel yourself getting uncomfortable (shivering, feeling numb, tingling or stinging), go inside and warm up.

8. Rich Meals

Oh, who can resist a rich, tasty meal that starts with hors d’oeuvres, flows with wine and ends with gooey chocolate dessert and maybe an digestif or two? Well, your heart may have something to say about that. Data shows that your risk for a heart attack is quadrupled within two hours of gorging on a heavy meal—even just one time—especially if you are already diagnosed with heart disease, according to UCI Health, California.

Protect Your Heart:

  • Eat healthy: Try having a high-protein snack such as yogurt, nuts, edamame or veggies in hummus dip before going to dinner. It will take the edge off and make it easier to pass up or limit some of the fattier entrees.
  • Practice moderation: Go easy on the hors d’oeuvres, so you aren’t already stuffed before you sit down. And when you do sit down, have that slice of dessert but don’t go for seconds or thirds, and skip the whipped cream.
  • Pace yourself: We tend to get excited at big meals and eat really quickly. Your body doesn’t even get time to register that it’s full before another forkful is coming down the hatch. Instead, take your time to savor each bite. Try this: Each time you take a bite, set your fork down while you chew. Then don’t pick it up again until you swallow your bite. After, take a walk before dessert to let your stomach settle and digest a little.

We may think we are doing all we can do to protect our hearts by quitting smoking or watching our weight – and yes, those are major steps – but it isn’t the whole story. The heart is a complex organ, and there are many factors involved in keeping it healthy and strong. Think about these eight additional heart attack triggers and how you can add in more protection to keep you going for years to come.

      Nice article. I think cold air on your lungs is very bad. I suggest you walk in a mall when it is very cold. Or use an indoor treadmill. I am 87 years old and walk without a cane or walker and I have excellent balance and still ride a two wheel bike and I don’t fall because I have been a walker all my life. I feel exercise is a very important thing to keep you young.

      Suggest taking a walk and skipping dessert. If you don’t bother sweets, they will not bother you. Sugar is addictive. Slice an orange. Thanks for helpful reminders.

    • Pamela | February 14, 2021 at 11:28 pm

      Very informative article. Although I have heard most of these points before, reading this article reminded me that I need to act on some of them to improve my overall health and avoid future problems. Thank you!

    • Linda M. Burke | February 14, 2021 at 3:55 pm

      It is odd that you recommend yogurt but suggest a pass on whipped cream. All dairy is bad in that, among other things, it aids the growth of cancer and diabetes, premature body changes in boys and girls, etc. See “The China Study” and the many YouTube videos on the negative effects of dairy.

      I enjoy reading articles from Hartford. I find them that although the information may not be new, you write it in more details and in ways that don’t make it sound like it came out of an encyclopedia.

      Thanks. I was not aware of the migraine connection to heart attacks and stroke.

    • Jack Lloyd | February 13, 2021 at 2:40 pm

      I find I disagree with the’’ Sleep’’ section on these recommendations, I believe that if your body is tired enough to require 10hrs sleep, then you should let that happen, & get out of bed at that time,….not sooner! The exception would be if you just HAVE to catch that Train or Flight. ( or you have a grumpy old boss at work )

    • Shawn | February 13, 2021 at 2:21 pm

      Great advice! Thank you Hartford for sharing all this informative information. Too many of us already know most of this info, however we tend to forget about it and need a gentle reminder.
      Namaste… 🙏

      Stop worrying about the things that you have no control over. Frequent worry causes anxiety which is bad for your heart. The other things you mention in this email are also helpful and healthy for your heart.

      An aperitif is before dinner, a digestif, after dinner.

      I was just introduced to an exercise program called, “Ageless Grace”. ( Many may already know it). It seems like a winner. I really enjoy your newsletter. Thank you. Please keep the brain games coming.:)

      • Pamela | March 10, 2021 at 3:42 pm

        Thank you for mentioning “Ageless Grace.” I had never heard of it. I looked it up, ordered it, and just received it. I think it is amazing and am looking forward to seeing results!

    • Linda | February 13, 2021 at 12:16 pm

      I went through your list and checked off what I should be doing. I can improve on some of them. I do feel I am better at these now that I am older. Thank you for making me reassess what I do,

    • E.J. Davis | February 13, 2021 at 12:07 pm

      Re: handwarmers in your boots — that’s a BIG no-no, as they can create enough heat to result in burns when used that way! Please use TOE-WARMERS — made for use in boots — instead. Both are made by a company called HotHands and are reasonably priced, available at Wal-Mart, many sporting goods stores, hardware stores, and more….

      Here’s a hot tip: hand-warmers (especially the 10-hour ones) can be re-used! When you come in from the cold, store them in a small glass jar (baby-food sized) with a tight lid. To use them again, shake them out, pinch any small lumps you feel, & let them begin to warm up before you insert them into your mitt or glove pocket. The foot-warmers are not so easy to restore due to moisture in your boots, but it’s worth a try!

      • Extra Mile Staff | February 13, 2021 at 7:08 pm

        E.J. – Thanks for the heads-up. We’ve updated to include toe warmers as well. Thanks for reading.

      I liked your suggestion to take a walk after dinner and before dessert!

    • Harriett Allen | February 13, 2021 at 11:06 am

      Lots of good thoughts and info here. Most I’m doing, but eating slower and walk before dessert is good idea. I live in an independent living facility so evening meal is excellent and served to us. Lots of temptation. The high-protein snack before dinner, I plan to try!

      • patricia A Denson | February 13, 2021 at 12:25 am

        Very helpful information, but I once read that you can cough hard when you feel some of the symptoms that was just mentioned. Is this a idea that works,because it worked for me before and when I did it it was when I had a rapid heartbeat after taking a prescribed medication. I ended up feeling just fine.

        Having a difficult time controlling my husband’s diet being that he is diabetic and severe blocked arteries. Not a candidate for surgery. And he has advanced RA which makes difficult for him to get around.
        Is there a good book for heart patient with diabetis? Type 2 diabetic on a long acting insulin shot. A
        A easy to understand book. I might add. Nutrition can be difficult 😢
