Introduction to Cardiovascular Health
Cardiovascular health involves the heart and blood vessels, the importance of which is known to all. The heart pumps blood into our blood vessels, which delivers oxygen to our organs, muscles, and the rest of our body. As we age, there will be changes to our heart and the blood vessels, that will cause restrictions in the way our cardiovascular system works. These changes include:
- Blocked or narrowed blood vessels that could cause a heart attack or stroke;
- The heart will have a more rigid structure, due to the muscles in the heart growing thicker;
- Decreased volume of the heart means lesser blood that will empty the heart in one beat, and more effort is needed to pump blood out;
- Hardening of the walls of our arteries. The artery itself originally has some elasticity which aids in pumping blood, however as it hardens, this function gradually diminishes;
- Problems with the heart’s muscle, valves or rhythm.
