People age 65 and older are much more likely than younger people to suffer a heart attack, to have a stroke, or to develop coronary heart disease(commonly called heart disease) and heart failure. Heart disease is also a major cause of disability, limiting the activity and eroding the quality of life of millions of older people.
How the heart changes with age
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 times of stress as it did when you were younger. However, the number of heartbeats per minute (heart rate) at rest does not change significantly with normal aging.
Changes that happen with age may increase a person’s risk of heart disease. A major cause of heart disease is the buildup of fatty deposits in the walls of arteries over many years. The good news is there are things you can do to delay, lower, or possibly avoid or reverse your risk.
The most common aging change is increased stiffness of the large arteries, called arteriosclerosis (ahr-teer-ee-o-skluh-roh-sis), or hardening of the arteries. This causes high blood pressure, or hypertension, which becomes more common as we age.
High blood pressure and other risk factors, including advancing age, increase the risk of developing atherosclerosis (ath-uh-roh-skluh-roh-sis). Because there are several modifiable risk factors for atherosclerosis, it is not necessarily a normal part of aging. Plaque builds up inside the walls of your arteries and, over time, hardens and narrows your arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body. Oxygen and blood nutrients are supplied to the heart muscle through the coronary arteries. Heart disease develops when plaque builds up in the coronary arteries, reducing blood flow to your heart muscle. Over time, the heart muscle can become weakened and/or damaged, resulting in heart failure. Heart damage can be caused by heart attacks, long-standing hypertension and diabetes, and chronic heavy alcohol use.
Other heart changes with age include:
- There are age-related changes in the electrical system that can lead to arrhythmias—a rapid, slowed, or irregular heartbeat—and/or the need for a pacemaker. Valves—the one-way, door-like parts that open and close to control blood flow between the chambers of your heart—may become thicker and stiffer. Stiffer valves can limit the flow of blood out of the heart and become leaky, both of which can cause fluid to build up in the lungs or in the body (legs, feet, and abdomen).
- The chambers of your heart may increase in size. The heart wall thickens, so the amount of blood that a chamber can hold may decrease despite the increased overall heart size. The heart may fill more slowly. Long-standing hypertension is the main cause of increased thickness of the heart wall, which can increase the risk of atrial fibrillation, a common heart rhythm problem in older people.
- With increasing age, people become more sensitive to salt, which may cause an increase in blood pressure and/or ankle or foot swelling (edema).
Other factors, such as thyroid disease or chemotherapy, may also weaken the heart muscle. Things you can’t control, like your family history, might increase your risk of heart disease. But, leading a heart-healthy lifestyle might help you avoid or delay serious illness.
