Final answer:
Atherosclerosis is the normal age change that progresses into heart disease, characterized by the build-up of plaque in artery walls, leading to cardiovascular issues such as heart attacks or strokes.
Step-by-step explanation:
The normal age change referred to in the question that progresses into heart disease is atherosclerosis. Atherosclerosis is characterized by the build-up of plaque in the walls of the arteries. This condition is a specific type of arteriosclerosis, which is the hardening of the arteries. When fat accumulates along the artery walls, it narrows the space for blood to flow and can lead to serious cardiovascular events such as a heart attack or stroke.
As individuals age, the incidence of heart diseases, like atherosclerosis, generally increases. This is because the arteries lose their elasticity and the capacity to accommodate blood flow efficiently, fostering conditions that contribute to plaque build-up. Atherosclerosis is considered a major health concern as it is one of the leading causes of heart disease and typically progresses over time. Genetic factors, lifestyle choices, and age are all influential in its development and progression. Understanding and checking the progression of atherosclerosis can play a significant role in preventing heart disease.
