Kuku Kohli Dies: Stents Cannot Reverse Existing Heart Damage

A heart attack happens when blood cannot reach part of the heart.

Without enough oxygen, heart muscle can become injured.

Doctors can use angioplasty and a stent to open the blocked artery.

This may help prevent more damage.

However, a stent cannot repair heart tissue that has already died.

It also cannot undo the damage from a heart attack that has already happened.

The longer the artery stays blocked, the more serious the injury may be.
