Heart Attacks in Winter

Winter means cooler temperatures and the holiday season, but did you know it also brings an increased risk of heart attack?  Studies show the risk of dying from a heart attack is greater in the winter than at any other time of year, with cardiac mortality at its highest in December and January. While the reasons for the increase in heart attacks are complex – including changes in hormone, stress and exertion levels – you can take steps to reduce your risk.

There are several reasons heart attacks are more frequent in winter.  First, during the winter months, changes in hormonal balances put individuals at greater risk for cardiovascular problems.  In addition, the colder temperatures cause arteries to tighten, restricting blood flow, reducing oxygen to the heart and causing blood pressure to increase, all of which can set the stage for a heart attack, especially in plaque-clogged arteries.  During winter months people tend to exercise and do yard work and other physical activity earlier in the day.  Since blood pressure rises naturally in the morning, increased exertion early in the day can contribute to heart attacks.  The flu season also may play a role in the increased number of heart attacks. The influenza virus may trigger inflammation of the heart, which may cause a heart attack.

The holidays may play a role in the increased number of heart attacks. People overindulge in food and alcohol, which often leads to weight gain and contributes to the risk for heart attack.  Alcohol has its own heart risks, increasing blood pressure, contributing to abnormal heart rhythms and increasing the risk of depression.  The hustle and bustle of the holiday season can also be a source of stress, with many people pressed for time and money.  Anxiety and depression tend to increase during this time of year, further increasing the risk of heart attack.

Though there are several reasons heart attacks are more common in winter, you can take steps to reduce your risk. First, avoid over-exertion and talk to your doctor about appropriate physical activity.  Winter chores such as shoveling snow can be particularly strenuous.  If you must shovel snow, take frequent breaks and be sure to bundle up and stay warm.  Experts recommend dressing in three layers: an inner layer that wicks away moisture, a middle layer that insulates the body and a top layer that repels rain and water.  If you are over 50 or have a history of health problems, get someone to shovel the snow for you.  If you are sore after shoveling snow, take symptoms seriously, as signs of a heart attack may be mistaken for a pulled muscle.

The holidays provide ample opportunities to eat and drink, but try to do so in moderation.  Avoid caffeine and nicotine, both of which can exacerbate heart problems, and consider taking at least 400 IU (international units) of vitamin D each day.  Low levels of vitamin D have been found more often in heart attack patients.  Finally, be sure to get your flu shot, which can cut your risk of heart attack in half.

In any season, the best medicine to ward off heart attacks is prevention: Cultivate heart-healthy habits, such as regular exercise, weight control, and a diet rich in fiber, fruits and vegetables.  Also, know your cholesterol, blood pressure and blood sugar levels.  Finally, to combat the holiday blues, take solace in the company of friends and loved ones.

How can I prevent a heart attack?

This is a question I am asked frequently, not only from patients, but also from friends and family. Cardiovascular disease mortality has dropped dramatically in the past 25 years, but still remains the leading cause of death in the U.S. What many people may not realize is that over 80% of heart attacks are PREVENTABLE! Yep, that’s right. Our diet and lifestyle choices dramatically affect our chances of developing heart disease. While genetics certainly play a role in our susceptibility to heart disease (and we still are in the infancy of understanding these genetics), this is felt to play a minor role in causality. You can play a MAJOR part in prevention.

Let’s list what you can do:

1. If you smoke, stop. Smoking increases your risk of having a heart attack by about 30%, and stopping smoking is the main preventive thing you can do. There are medications and counseling available that may help you quit.

2. Diet is important. In the the 1950’s, Japan had a low incidence of heart disease. But starting in the 1960’s, this started to change significantly. What happened? McDonalds and other fast food outlets moved in, and the typical Japanese diet of fish, rice and vegetables started to change to a high fat, high calorie Western diet. Coincidence? Unlikely. What has been shown is that a Mediterranean type diet of fresh fruit and vegetables, fish, and nuts does lower risk. The South Beach Diet was written by a cardiologist and is a good resource for healthy eating that I frequently recommend. Does that mean you have to completely give up mac and cheese or fried chicken? No, but when given a choice, maybe go with the healthier alternative on a regular basis, and save those for weekends or holidays.

3. Maintain a reasonable weight. I know, it’s hard. But being overweight is tied to increased risk of high blood pressure, higher cholesterol and diabetes, which are all risk factors for heart attacks.

4. Regular exercise. I’m not asking you to run the Mercedes Marathon. Simply walking for 30 minutes five days a week lowers risk by 25-30%. If you want to do more, that’s great!

5. “Hey, Doc…I take an aspirin every day. I should be good”. Not so fast. Aspirin is certainly good for those with a history of cardiovascular disease (heart attack, stroke, etc.), but several large recent studies show that it has little benefit for primary prevention, and actually may be harmful, since it increases bleeding risk.

6. How about statins (cholesterol lowering drugs) like Lipitor? Should we just put them in the drinking water? Absolutely not. The benefits really depend on your baseline risk, such as diabetes, high blood pressure, and your cholesterol levels. Doctors now even have computer programs that can quickly give us the risk/benefit levels of starting these medications that can be discussed during your office visit.

To sum things up, an ounce of prevention is at least worth a pound of cure when it comes to heart disease. Get off the couch, eat better, and quit smoking. It can make a difference!
