Smoking

Smoking causes heart disease and can be even more dangerous for women than men. Women over 35 who smoke have a slightly higher risk of dying from heart disease compared to male smokers over 35.1 Smokers are up to four times more likely to have heart disease than nonsmokers. Even smoking in your 20s speeds up the process of developing heart disease.2

Smoking raises your risk for heart disease in many ways, including:

  • Smoking can cause your blood to thicken and be more likely to clot.
  • The nicotine in cigarettes can raise your blood pressure.
  • Smoking causes atherosclerosis, which damages your blood vessel walls.

The longer you smoke, the more your risk of heart disease and heart attack goes up.

But within one year of quitting smoking, your heart disease risk is cut in half compared to what it was while you smoked. Within 15 years, your heart disease risk is the same as a woman who never smoked.2

If you smoke, do not use hormonal birth control. Many studies have found that women who smoke and take combination birth control pills (birth control pills with both estrogen and progesterone) are at even higher risk of heart disease and stroke, especially women older than 35. Like smoking, birth control pills, and possibly other forms of combination hormonal birth control like the vaginal ring or skin patch, can raise your risk for blood clots and high blood pressure. Blood clots and high blood pressure can cause a heart attack or stroke.

Secondhand smoke also can harm the heart and blood vessels of people who don't smoke in the same way that smoking harms people who smoke.3 There are two types of secondhand smoke. One type is the smoke that comes from the burning end of a cigarette, cigar, or pipe. The other type is smoke that is breathed out by someone who is smoking. Both types are harmful when inhaled.

E-cigarettes and your heart health

Electronic or e-cigarettes, also called vaporizer cigarettes, release water vapor. Most e-cigarettes contain nicotine, the addictive chemical found in regular cigarettes. The Food and Drug Administration regulates e-cigarettes and all other tobacco products. Researchers do not yet know the potential long-term health effects of e-cigarettes or how much nicotine or other harmful chemicals are inhaled.

Researchers also do not yet know what effect e-cigarettes have on heart health. Talk to your doctor about the dangers of e-cigarettes to your health.

Eating habits

What you eat is a big part of preventing heart disease and other chronic (long-term) diseases like type 2 diabetes. Eating healthy can also prevent other health problems that lead to heart disease, like high blood pressure or obesity.

There is no special vitamin or ingredient that can prevent disease. Healthy eating to prevent chronic diseases means eating a healthy combination of foods from all of the food groups. Use the interactive SuperTracker tool at ChooseMyPlate.gov to create a personalized healthy eating plan based on your age, height, weight, physical activity level, and goals.

Eating healthy also means you do not eat a lot of food with saturated fat or trans fat, sodium (salt), or added sugar.

Physical activity

Less than one in every five American women gets enough physical activity to help prevent heart disease.4 Being inactive is a major risk for heart disease.

The heart is like any other muscle: the more you work it, the stronger it gets. Physical activity also helps keep your blood vessels flexible and open so the blood can reach all of your organs. It can help prevent the buildup of plaque in the arteries. Being active also can prevent other risk factors for heart disease. These include high blood pressure, diabetes, and obesity.

You need to get at least 30 minutes of physical activity five times a week to stay healthy. Learn more about physical activity.

Alcohol

If you don't already drink, don't start drinking for health reasons. Researchers are not sure that even one drink per day for women (or less) is heart healthy. More than three drinks a day can raise blood pressure and triglyceride levels and can damage your heart muscle. In women, there is strong evidence that alcohol increases your risk of breast cancer.5 

There are many women who should not drink any alcohol, including

  • Pregnant women or women trying to get pregnant
  • Women younger than 21
  • Women taking certain medicines (ask your doctor or nurse)

No amount of alcohol is recommended in the Dietary Guidelines for Americans because the potential risks and harms outweigh any benefit.

Stress

Stress is your body's response to a change or a challenge. Long-term stress raises your risk of heart disease. If you have heart disease, long-term stress also makes you more likely to have a heart attack.

An emotionally upsetting event, especially one involving anger, can be a trigger for heart attack.6 Stress also may indirectly raise your risk of heart disease if it makes you more likely to smoke, eat unhealthy foods, or less likely to exercise.
