This may explain why many older people have orthostatic hypotension, a condition in which the blood pressure falls when a person goes from lying or sitting to standing. The baroreceptors become less sensitive with aging. Receptors called baroreceptors monitor the blood pressure and make changes to help maintain a fairly constant blood pressure when a person changes positions or is doing other activities.A heart murmur caused by valve stiffness is fairly common in older people. The valves inside the heart, which control the direction of blood flow, thicken and become stiffer. The heart muscle cells degenerate slightly. ![]()
