What is the treatment for an obstructed coronary?

Explanation:
Restoring blood flow by opening a blocked coronary artery is the key idea. A stent is a tiny mesh tube placed during a catheter-based procedure to reopen the narrowed artery and hold it open, which directly relieves the obstruction and improves blood supply to the heart muscle. ACE inhibitors help manage blood pressure and heart remodeling after injury, but they don’t remove the blockage. Pacemakers correct rhythm problems, not a blocked artery. Statins lower cholesterol and help stabilize plaques to reduce future risk, but they don’t immediately relieve an existing obstruction. So the option that directly addresses the blockage is a stent.
