Caring for Your Heart

Many people think of heart disease as a problem for men, yet it is a leading cause of death for women worldwide. According the World Health Organization (WHO), heart disease and stroke were the top two causes of death among women overall in 2012, though the leading cause of death in girls and women ages 15-44 years was HIV/AIDS.
In the US, heart disease was also the number one cause of death for women in 2013, accounting for about one in four of all female deaths. By comparison, breast cancer caused only one in 31 deaths among women in the US. Almost two-thirds of women who died suddenly of coronary heart disease had no symptoms of heart trouble before they died. This is why it is important to get regular check-ups and understand your risk for heart disease (see Risk Factors of Heart Disease below).
Heart disease is a type of cardiovascular disease (CVD). This means that it affects your heart and blood vessels. There are several types of heart disease. The most common type in the US is coronary artery disease (CAD), or coronary heart disease (CHD). It affects the blood vessels that supply the heart muscle and is most commonly associated with heart attacks. Another type is cerebrovascular disease, which affects the blood vessels that supply the brain. This type is most commonly associated with strokes.
CAD or CHD occur when hard patches, called plaques, build up in the blood vessels that supply blood to the heart. Plaque is made up of cholesterol, a fat-like substance found in the blood. Plaque buildup causes the arteries (blood vessels leading to the heart) to get narrower and become less flexible. This process is called atherosclerosis.
A heart attack occurs when a plaque breaks free from a blood vessel's wall and forms a clot that blocks an artery that is supplying blood to your heart. Because of this blockage, the oxygen-rich blood that the heart needs to pump cannot reach the heart. As a result, part of the heart muscle may become injured or die.
Recent studies have shown that statins, a type of cholesterol-lowering drug, may reduce the amount of plaque in the blood vessels of people living with HIV. Thus, statins may help to reduce the risk of heart disease in people living with HIV. For more information, see the section "Reducing the Risk for Heart Disease" below.
For some people, the first sign of heart disease is a heart attack. Symptoms of a heart attack include:
As with men, women's most common heart attack symptom is chest pain or discomfort. However, one study reported that four in ten women experienced no chest pain during a heart attack. In 2016, the American Heart Association confirmed that women are more likely than men to have some of the other common symptoms, particularly shortness of breath, nausea or vomiting, and back or jaw pain. Many women who have suffered a heart attack report that they simply felt like they had indigestion. If you feel heart attack symptoms, seek medical attention immediately.
Two out of every three women who die suddenly of coronary heart disease do not have any symptoms beforehand. You therefore should know your risk factors for heart disease and maintain good heart health. One of the most important factors is family history. If someone in your family has had heart disease, you are at greater risk for problems with your heart.
Age and gender also affect heart health. Generally, men are at greater risk than women and at an earlier age. For men, risk begins to go up at age 45 and continues to grow each year. For women, the risk generally does not start to go up until after menopause, when women lose the protective effect of estrogen. By age 65, the heart disease risk in women rises substantially.
Some studies have shown that taking hormone replacement therapy (HRT) may increase a woman's risk for heart disease, stroke, pulmonary embolism (blood clot in the lung), and breast cancer. For some women, the benefits of hormone replacement therapy outweigh the risk of heart disease. If you are thinking about hormone replacement therapy, talk to your health care provider so that you can decide what is right for you.
Other risk factors for heart disease include:
People living with HIV (HIV+) have higher rates of heart disease than the general population. There are a number of reasons for this:
While some HIV drugs can cause side effects that may increase the risk of heart disease, studies have shown that HIV medications may actually protect against heart disease, as well as keep HIV and other HIV-related conditions under control.
A recent study from Denmark also suggests that the primary reason for the higher risk of heart disease in people living with HIV is that people living with HIV smoke more than those who are HIV-negative. If there is one thing you can do to improve your heart health -- and your health overall -- it is to quit smoking. For more information and suggestions on how to quit, see our article on Smoking and Tobacco Use.
People living with HIV should find out about their risk factors for heart disease and take steps to reduce them. Ask your health care provider about the HIV drugs you take to see if any may be raising your lipid (cholesterol and triglyceride) levels. Some newer classes of drugs may not affect your lipids as much. Switching drugs may not be an option for everyone. It is important that you not make any changes to your HIV drugs without first talking to your health care provider.
While there are some risk factors that you will not be able to change, there are many things that you can do to reduce your risk for heart problems:
Statin drugs are used to lower cholesterol and prevent heart disease. Early studies among people living with HIV also found that statins could reduce inflammation. Some scientists believe that inflammation is the key to the process of 'accelerated aging' that affects some people living with HIV. A large clinical trial called REPRIEVE is currently underway to examine the ability of a statin drug called pitavastatin to reduce inflammation and heart disease among people living with HIV.
Your health care provider can determine your risk for heart disease by checking your blood pressure, cholesterol, and blood sugar, and by finding out about your family's history of heart disease. If you are at high risk or already have symptoms, your provider may suggest tests that can determine if you have heart disease. Medications may also be necessary. Medicines can treat heart disease risk factors, such as high lipid levels, high blood pressure, diabetes, an irregular heartbeat, and low blood flow.
Heart disease is a growing concern for both men and women living with HIV. One reason is that people are living longer with HIV because effective HIV drugs are used widely. The risk of heart disease increases naturally as you age.
The good news is that there are many things you can do to help prevent and manage heart disease. Healthy lifestyle choices, such as quitting smoking, improving your diet, getting regular medical checkups, and staying physically active, can all help you care for your heart. When lifestyle changes are not enough, several medications and other medical approaches are available.
