How effective is a coronary stent for treating coronary artery disease (cad)?

Stent: When treating an obstructed coronary artery with a stent is the appropriate treatment, the stent if properly placed and without complications is usually 90-95% effective at relieving the symptoms associated with the obstructed artery. Stenting is not necessarily appropriate for all patients and treatment needs to be individualized. Discuss with your cardiologist.
