“Under normal circumstances, the heart continues to adequately supply all parts of the body. However, an aging heart may be slightly less able to tolerate increased workloads, because changes reduce this extra pumping ability (reserve heart function).”
As we age, there are changes that take place in our hearts, our vessels, and our blood. Some of the changes that take place in the heart itself are: a decrease in the rate of the heart due to cell loss in the SA node or commonly known as our natural pacemaker; an increase in the size of the heart along with thickening of the walls of the heart, which can result in a decrease in the amount of volume that the heart can hold; deposits of lipofuscin or also known as the “aging pigment”; valve stiffness, which can result in a heart murmur; and abnormal rhythms as well as degeneration of muscle cells in the heart. This MedlinePlus article serves to acquaint you with the changes that take place in other parts of the circulatory system mentioned above, such as the changes that take place in the blood and in our blood vessels. The article, not only gives you information about the changes that take place in our cardiovascular system as we age, but also about actions you can take right now to keep your cardiovascular as healthy as possible for as long as possible.
