Question
D. The Aging Heart Valve Challenge Your grandmother, who nas been a non-smoker and relatively healthy throughout her life, has recently noticed that she is becoming increasingly short of breath as she does simple things (such as climbing the steps in her house). She has also noticed that her heart rate increases when she does mild exercise (such as climbing the stairs or walking outside to get the mail). Think about the following: What could be causing this? Is it just due to her getting older? Is there reason to be concerned? What can be done to help her? Identify which statement/s are correct based on the situation above? a. Aged person's heart can't beat as fast during physical activity or times of stress as it did when you were younger. The number of heart beats per minute (heart rate) at rest does not change significantly with normal aging. b. The most common aging change is increased stiffness of the large arteries, called arteriosclerosis, or hardening of the arteries. C. With increasing age, people become more sensitive to salt, which may cause an increase in blood pressure and/or ankle or foot swelling (edema). d. Aged individuals loose muscle coordination and strength. The chambers of your heart may increase in size. e. f. There are age-related changes in the electrical system that can lead to arrhythmias-a rapid, slowed, or irregular heartbeat. Valves 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). O
