Heart disease in women: Understand symptoms and risk factors

All women face the threat of heart disease. But becoming aware of symptoms and risks unique to women, as well as eating a heart-healthy diet and exercising, can help protect you.

Although heart disease is often thought of as a problem for men, more women than men die of heart disease each year. One challenge is that some heart disease symptoms in women may be different from those in men. Fortunately, women can take steps to understand their unique symptoms of heart disease and to begin to reduce their risk of heart disease.

Heart attack symptoms for women

The most common heart attack symptom in women is some type of pain, pressure or discomfort in the chest. But it's not always severe or even the most prominent symptom, particularly in women. And, sometimes, women may have a heart attack without chest pains. Women are more likely than men to have heart attack symptoms unrelated to chest pain, such as:

  • Neck, jaw, shoulder, upper back or abdominal discomfort
  • Shortness of breath
  • Right arm pain
  • Nausea or vomiting
  • Sweating
  • Lightheadedness or dizziness
  • Unusual fatigue

These symptoms can be more subtle than the obvious crushing chest pain often associated with heart attacks. Women may describe chest pain as pressure or a tightness. This may be because women tend to have blockages not only in their main arteries but also in the smaller arteries that supply blood to the heart — a condition called small vessel heart disease or microvascular disease.

Women's symptoms may occur more often when women are resting, or even when they're asleep. Mental stress also may trigger heart attack symptoms in women.

Women tend to show up in emergency rooms after heart damage has already occurred because their symptoms are not those typically associated with a heart attack, and because women may downplay their symptoms. If you experience these symptoms or think you're having a heart attack, call for emergency medical help immediately. Don't drive yourself to the emergency room unless you have no other options.

Heart disease risk factors for women

Although the traditional risk factors for coronary artery disease — such as high cholesterol, high blood pressure and obesity — affect women and men, other factors may play a bigger role in the development of heart disease in women. For example:

  • Diabetes increases the risk of heart disease significantly more in women than in men.
  • Metabolic syndrome — a combination of fat around your abdomen, high blood pressure, high blood sugar and high triglycerides — has a greater impact on women than on men.
  • Mental stress and depression affect women's hearts more than men's. Depression makes it difficult to maintain a healthy lifestyle and follow recommended treatment, so talk to your doctor if you're having symptoms of depression.
  • Smoking is a greater risk factor for heart disease in women than in men.
  • A lack of physical activity is a major risk factor for heart disease, and as a group, women tend to be less active than men.
  • Low levels of estrogen after menopause pose a significant risk factor for developing cardiovascular disease in the smaller blood vessels (microvascular disease).
  • Pregnancy complications such as high blood pressure or diabetes during pregnancy can increase a woman's long-term risk of high blood pressure and diabetes and increase the risk of development of heart disease in both the mother and in her children.

Is heart disease something only older women should worry about?

No. Women under the age of 65, and especially those with a family history of heart disease, need to pay close attention to the heart disease risk factors. Women of all ages should take heart disease seriously.

What can women do to reduce their risk of heart disease?

There are several lifestyle changes you can make to reduce your risk of heart disease:

  • Quit or don't start smoking.
  • Exercise 30 to 60 minutes a day on most days of the week, or 60 to 90 minutes if you need to lose weight.
  • Maintain a healthy weight.
  • Eat a diet that's low in saturated fat, cholesterol and salt.

You'll also need to take prescribed medications appropriately, such as blood pressure medications, blood thinners and aspirin. And you'll need to better manage other conditions that are risk factors for heart disease, such as high blood pressure, high cholesterol and diabetes.
