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.
The article explains the limits of stents in treating heart damage.
Doctors explain that a stent opens a blocked coronary artery.
A stent cannot undo heart muscle damage caused by an existing heart attack.
A heart attack occurs when a blocked coronary artery cuts off oxygen-rich blood.
The longer the blockage remains, the greater the risk of permanent heart muscle injury.
Angioplasty and stenting can restore blood flow and limit further damage, but cannot revive dead heart tissue.
