As a result, blood pressure rises and the arteries weaken. This can lead to rapid rupture of the blood vessels, also known as heart attack or brain stroke. In some cases the arteries lose elasticity over old age. Heart stent or coronary stent inserts in the blocked/fragile region of coronary artery. It helps to expand the artery to allow free flow of blood and consequently, reduces blood pressure. Over past 20 years there are many modifications and innovations in the field of cardiac stents, in this chapter we will discuss few of those.
