Answer:
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. 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.
