Your heart is a strong muscle about the size of the palm of your hand. Just like an engine makes a car go, the heart keeps your body running. The heart has two pumps. The stronger pump uses arteries to send blood with oxygen away from the heart, throughout the body. The other pump uses veins to bring blood back to the heart and sends it to the lungs to get more oxygen. An electrical system in the heart controls the heart’s pumps (the heart beat or pulse).
Aging can cause changes in the heart and blood vessels. For example, as you get older, your heart can’t beat as fast during physical activity or stress as when you were younger. However, the number of heart beats per minute (heart rate) at rest does not change as you age.
Many of the problems older people have with their heart and blood vessels are really caused by disease, not by aging. For example, an older heart can normally pump blood as strong as a younger heart; less ability to pump blood is caused by disease. But, changes that happen with age may increase a person’s risk of heart disease. The good news is there are things you can do to delay, lower, or possibly avoid or reverse your risk.
A common problem related to aging is “hardening of the arteries,” called arteriosclerosis (ahr-teer-ee-o-skluh-roh-sis). This problem is why blood pressure goes up with age.
Age can cause other changes to the heart. For example:
- Blood vessels can become stiffer, and some parts of the heart wall will thicken to help with blood flow.
- Your valves (one-way, door-like parts that open and close to control the blood flow inside your heart) may become thicker and stiffer, causing leaks or problems with pumping blood out of the heart.
- The size of the sections of your heart may increase.
Other factors, such as thyroid disease or chemotherapy, may weaken the heart muscle. Things you can’t control, like your family history, might also increase your risk of heart disease. But even so, leading a heart-healthy lifestyle might help you avoid or delay serious illness.
There are many different kinds of heart disease. The most common is atherosclerosis (ath-uh-roh-skluh-roh-sis), the buildup of fatty deposits or plaques in the walls of arteries. As plaque builds up, there is less space for blood to flow normally and deliver oxygen throughout the body, including to the heart. Depending on where the buildup is, it can cause a heart attack, leg pain, or a stroke. Atherosclerosis is not part of normal aging and can be serious. There are choices you can make to prevent or delay heart disease, including:
- Don’t smoke
- Stay at a healthy weight
- Avoid spending hours every day sitting
- Keep your diabetes, high blood pressure, and/or high cholesterol under control
- Manage your stress
- Don’t drink a lot of alcohol
Early heart disease often doesn’t have symptoms, or the symptoms may be barely noticeable. This is especially true in older adults. That’s why regular checkups with your doctor are important.
Contact your doctor right away if you feel any chest pain. However, as you get older, chest pain is a less common sign of heart disease, so be aware of other symptoms. Tell your doctor if you feel:
- Pain in the shoulders, arms, neck, jaw, or back
- Shortness of breath when active or at rest
- Chest pain during physical activity that gets better when you rest
- Cold sweats
- Easily tired or fatigued
- Swelling in the ankles, feet, legs, stomach, and/or neck
- Less able to exercise or be physically active
- Problems doing your normal activities
Problems with a rapid or irregular heartbeat are much more common in older adults than younger people and need to be treated. See a doctor if you feel a fluttering in your chest or have the feeling that your heart is skipping a beat or beating too hard, especially if you are weaker than usual, dizzy, or tired.
If you have any signs of heart disease, your doctor may send you to see a cardiologist, a doctor who specializes in the heart.
There are a lot of steps you can take to keep your heart healthy.
Try to be more physically active. Talk with your doctor about the type of activities that would be best for you. If possible, aim to get at least 30 minutes of moderate-intensity activity on most or all days of the week. Every day is best. It doesn’t have to be done all at once—10-minute periods will do. Start by doing activities you enjoy—brisk walking, dancing, bowling, bicycling, or gardening, for example. Visit Go4Life®, an exercise and physical activity campaign from the National Institute on Aging (NIA) at NIH, designed to help you fit exercise and physical activity into your daily life.
If you smoke, quit. Smoking adds to the damage to artery walls. It’s never too late to get some benefit from quitting smoking. Quitting, even in later life, can over time, lower your risk of heart disease and cancer.
Follow a heart-healthy diet. Choose low-fat foods and those that are low in salt. Eat plenty of fruits, vegetables, and foods high in fiber like those made from whole grains. And if you drink alcohol, men should not have more than two drinks a day and women only one. Get more information on healthy eating from NIA. The National Heart, Lung, and Blood Institute (NHLBI) has information on two eating plans—Therapeutic Lifestyle Changes (TLC) and Dietary Approaches to Stop Hypertension (DASH).
Keep a healthy weight. Your healthcare provider will probably check your weight and height to learn your BMI (body mass index). A BMI of 25 or higher means you are at greater risk for heart disease as well as diabetes (high blood sugar) and other health conditions. Extra fat around the middle of your body may increase your risk of heart disease. A man’s risk of heart disease is increased if his waist measures more than 40 inches. A woman’s risk is increased at 35 inches. Following a healthy eating plan and being physically active might help you.
