September 3 – Hearty Recommendation

Today’s factismal: Your heart will beat nearly 3,000,000,000 times during your life.

Quick! If you are a woman, gather three of your female friends. Odds are that one of the four of you has heart disease. That’s because 42.9 million women in the USA, or about 28% of the female population has heart disease. And it isn’t just women who suffer from this; about one in every twelve men has heart disease. And heart disease is the number one killer in the USA, accounting for nearly a quarter of all deaths. Heart disease kills more Americans than accidents, diabetes, kidney failure, influenza, suicide, and murder combined.

And heart disease takes many forms. There’s atrial fibrillation, where the top part of the heart beats in 9/7 time while the bottom part does a waltz. There’s coronary artery disease, where the pipes that lead to your heart get clogged up with fatty plaque. There’s heart failure, where the heart moves only a little blood even when your body wants a lot. And then there’s a heart attack, where your heart just throws in the towel and decides to take a rest on the sidelines for a bit.

Fortunately, there are almost as many ways to combat heart disease as there are types of heart disease. Adding just 30 minutes of light exercise each day by walking, working in the garden, or going for a bike ride, is enough to reduce the effects of heart disease by nearly 3/4. Eating a low-fat, low salt diet cuts the risk of stroke and heart attack by more than 1/3. And keeping an upbeat attitude has also been shown to improve health (and to get you more friends to share those long walks with).

Of course, there is more to having a healthy heart than just diet and exercise; genetics and other factors also play a part. And right now, a group of scientists are putting together a “big data” experiment to see just how much each of these things contributes to a healthy heart. At Health eHeart (get it?) they are asking for volunteers to take part in a study that will track participants for ten years. Every six months they’ll ask you to fill out a questionnaire on your health and will ask you to contribute information on your weight and activity level; some participants may also be given the opportunity to do cool things like wear a Holter monitor for a week or have a genetic sample taken.
