15 Weird Things Linked to Heart Attacks

Where you live can boost your risk.

Sept. 10, 2013— -- intro: When it comes to heart attacks, most people think a steady diet of greasy food and sedentary living is to blame.

While it's true that diet and lifestyle play a role (not to mention, family history), there are other, less common factors linked with heart trouble.

Here are some weird things that you would never think could potentially harm your heart.

The researchers looked at heart attacks over a 9-year period in people aged 45 to 64 living in four states.

"It's very true and something you can't do much about other than change where you live or spend time in places where the air quality isn't so toxic," says Malissa J. Wood, M.D., co-director of the Corrigan Women's Heart Health Program at the Massachusetts General Hospital Heart Center.

The evidence was not strong enough to change current practice, says Dr. Wood, although it is a good idea to talk with your doctor about alternative antibiotics if you have heart disease.

(Consult your doctor about taking calcium; some research suggests calcium can protect the heart.)

"I tell patients to get calcium in their diet," Dr. Wood says. "Eat oily fish twice a week along with other foods that have calcium and get outdoors for vitamin D."

The reason: Infections can bring on an inflammatory response, which can trigger a heart attack or stroke.

A flu vaccine may help protect against infection-induced heart stress.

Patients with severe psoriasis, a skin condition that usually requires medical treatment, are more likely to smoke, be overweight, and have high blood pressure, but Dr. Gelfand's research shows that psoriasis is an independent risk factor. He points out that psoriasis is an autoimmune disorder that may cause chronic inflammation, which can trigger a heart attack.

In fact, autoimmune diseases are a risk factor in general. Dr. Wood says the number-one cause of death among people with lupus is heart attack.

The study concluded that low HDL was the third strongest predictor of coronary events, after prior heart disease and age.

"If young people have heart attacks, I can almost always tell you they have low HDL," says Dr. Wood, author of Smart at Heart. Dr. Wood says there are ways to increase good cholesterol. The two most powerful tools? Exercise and weight loss.

Another study of 10,000 men found that those with chronic kidney disease had a two-fold greater risk of heart attack than those who didn't.

Another earlier study found that death from cardiopulmonary causes was nearly twice as high among people living close to a major road.

"If you have or are at risk for heart disease and want to stop taking aspirin, do so gradually and under the supervision of a doctor," warns Matthew Sorrentino, MD, a cardiologist at the University of Chicago.

A 2009 study in the Journal of the American College of Cardiology found that women with depression were twice as likely to develop heart disease over time than those who weren't depressed.

Other studies have linked job strain with a 23 percent increase in risk as well.

The connection is thought to be mouth bacteria, which can trigger chronic inflammation in the blood vessels.

"If you have disease in the vessels in one place in your body, you have them in other vessels as well," Dr. Wood says.

People with diabetes are about two to four times as likely to die of heart disease than their same-age peers without diabetes.
