Caring for Your Heart if You Have HIV/AIDS

Heart Disease Basics

Many people think of heart disease as a problem for men, yet heart disease 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 2011, though the leading cause of death in females ages 15-44 years was HIV/AIDS. In the US, five times as many women die from heart attacks each year as die from breast cancer.

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), also known as coronary heart disease (CHD). Over seven million women in the US were living with CHD in 2011. Worldwide, over seven million people died from CHD in 2008. Low- and middle-income countries are most affected; over eight out of ten deaths from CVD occur there, and affect women and men equally.

CAD occurs when hard patches, or plaques, build up in the 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 supplying blood to your heart. This blockage means that the oxygen-rich blood necessary for the heart to pump cannot reach the heart and part of the heart muscle may become injured or die. CAD can also lead to heart failure or an irregular heartbeat (arrhythmia).

Symptoms of Heart Attack

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, women are somewhat 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, do not delay -- seek medical attention immediately.

Risk Factors for Heart Disease

Two out of every three women who die suddenly of CHD do not have any prior symptoms, so it is important to know your risk factors for heart disease and to maintain good heart health. Many factors can increase your risk for heart disease. One of the most important is family history. If someone in your family has had heart disease, you have a higher risk.

Age and gender also have an effect on heart health. Generally, men have a 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 goes up 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 HRT outweigh the risk of heart disease. If you are thinking about HRT, it is important to talk to your health care provider so that you can decide what is right for you.

Other risk factors for heart disease include:

HIV and Heart Disease

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 drug therapy may actually protect against heart disease, as well as keep HIV and other HIV-related conditions under control.

Reducing the Risk for Heart Disease

It is important for HIV+ people to evaluate 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 and 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:

Taking Care of Yourself

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 some 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 HIV+ men and women. One reason for this is that HIV+ people are living longer due to the widespread use of effective HIV drugs, and the risk of heart disease increases naturally as you age.

The good news is that there are many things that you can do to help prevent and manage heart disease. Healthy lifestyle choices such as quitting smoking, improving your diet, getting regular medical check ups, and staying physically active can all help you care for your heart. When lifestyle changes are not enough, a number of medications and other medical approaches are available.
