Heart attack signs in women may differ

What causes a heart attack in women? Pretty much the same things that cause a heart attack in men. Smoking, high cholesterol levels, high blood pressure, inactivity, excess weight, diabetes, and a family history top the list. But what signals that a woman may be having a heart attack can be quite different.

Signs and symptoms

Women are more likely than men to describe their chest pain as sharp and burning, and they more frequently report nausea, fatigue, or difficulty breathing, dizziness, or jaw, neck, or upper body pain.

What’s more, a woman’s symptoms are more likely to be triggered by stress and less likely to be triggered by exertion. “I was going through a lot of stress at the time of my heart attack,” says heart attack survivor Sue Chlebek  of La Porte, Indiana.  “It’s something I still struggle with. I can control what I put in my mouth and how often I exercise. Controlling stress is harder.”

Not just a man’s disease

Then there’s the notion that only men have to worry about heart disease. “Many women think that it’s a man’s disease and that it can’t happen to them,” says Mary Ann Bauman, an Oklahoma City internist and the American Heart Association’s 2012 Physician of the Year. So they may ignore the risk. “Women are far more likely to bug their husbands about getting to the doctor than they are to do the same for themselves,” notes Bauman.

“If you ask, the majority of women will say breast cancer is their major risk for a fatal disease,” she adds. “And 40,000 American women do die of breast cancer each year, which is terrible.” But by age 55, heart disease deaths surpass breast cancer deaths, and after age 75, heart disease kills eight times more women than breast cancer.

“I thought breast cancer was my greatest risk,” says Sue Chlebek. “Every year I’d have my mammogram and my pap smear. I always thought, ‘Oh, heart disease. When I’m 70 or 80, it may be a risk for me.’ But not when I had barely turned 50, with a six-year-old.”

Diagnosing heart disease in women

It can be difficult for physicians to tell that a woman has heart disease, notes Bauman. “That’s because the disease may develop differently in women, and the common diagnostic tests are more accurate in men.”

Men are more likely to have obstructive coronary artery disease, where a blood vessel that brings oxygen to the heart muscle gets blocked, says Bauman. Those kinds of blockages can readily be seen on an angiogram, which tracks blood flow with an X-ray and a dye injected into the bloodstream.

But in women, heart disease is more likely to occur in the tiny blood vessels, which may be no wider than a human hair. The problem isn’t that plaque blocks the tiny vessels, but that their inner walls become damaged. The damage can cause spasms and cut off blood flow to the heart muscle. That’s a heart attack.

“Our blood vessels are more than just pipes that blood flows through,” Bauman explains. “They’re actually organs that expand and contract in response to the need for blood flow.”

The type of heart disease that’s more common in women, called small artery disease or coronary microvascular disease, can’t easily be detected with the usual tests—an angiogram or cardiac catheterization—that work well in men. “So other tests, such as a stress test, may be necessary to make the diagnosis in women,” says Bauman.

Bauman’s bottom line: “Most heart disease is preventable if you pay attention to the risk factors. You can’t change your family history, but you certainly can exercise, lose weight, and eat better.”

  1. I had a heart attack 9 years ago, and know I’m a vegan. The best way to test for an MI is a blood test that checks for high levels of the protein Troponin, which is produced by a severely stressed heart muscle. That was the key for saving my life. Previously, after a routine of doing a daily interval training walk/run up a steep hill, I had had shortness of breath, a pain in my upper back, and indigestion. I had seen 4 different doctors in a period of 2 months. They usually told me to take an antacid pill, and didn’t relate any of my symptoms to a heart problem. But then again, I’m a male !

  2. My first MI (myocardial infarction) woke me at 2am with terrible pain very low in my abdomen (supra-pubic pain). I thought I had gas. Long story shortened: On the third day I awoke again at 2am with the pain. This time it did not abate. I got an urgent appointment with a MD in my Doc’s office (she had no openings). I told him I thought I had intestinal problem. He asked to listen to my heart. I was irked and said, “You’re not listening to me. The pain is down here,” He begged and I said “OK.” He immediately had me hooked to an EKG and then screamed to the front office to call the EMTs. I was still having the MI. As soon as the ER got me stabilized I was transported to the nearest cardio unit (14 miles-I coded on the way) where I was instantly taken into surgery for stents to open three arteries. I had NO signs/symptoms of angina, which I’d had for 20years, nor any s/s of cardiac problems I could discern. I am a nurse and had worked CCUs, ERs and thought I knew my body and how to tell if I had heart problems. Suprise! I tell everyone about my low-ABD pain as a warning to all.
