Question

Assume the prevalence of CAD decreases with age after age 70; however, the incidence continues to increase with age. What is the most probable explanation for the divergence of these rates?

Answer 1

Answer: In normal healthy young people, the cardiovascular system works smoothly i.e. the heart pumps the blood, heart rate normal etc. But as we grew old, the activities of cardiovascular system also decreases. This is due to aging process.

As age increases, the working of cardiovascular system decreases as there are many reasons for this. The excess of cholesterol levels in the artery, presence of any kind of heart diseases, medications etc. are the some factors which contributes slow working of the heart at the old age.

As the age increases, the peacemaker loose some of its cells, this results into slower heart rate. The baroreceptor maintains the blood pressure in young people and function normally but it's function decreases with the aging process which is the main reason that elder people generally have blood pressure problem.
