Ageing causes the following changes to the heart –
1. Blood vessels become stiffer and thicken that disturbs the blood flow.
2. Heart valves become thicker and stiffer, causing leaks or problems with pumping blood out of the heart.
3. Certain sections of the heart may increase in size
4. Fatty deposition on the walls of arteries (atherosclerosis).
5. Hardening of the arteries (arteriosclerosis)
