I have 5 coronary artery stents. on average, how long will they remain effective?

Coronary stents: The rate of recurrence of blockage with either drug eluting or bare metal stents at 4-5 years is about 1-2%. If you control your coronary artery risk factors such as high cholesterol, diabetes or high blood pressure, and take antiplatelet medications such as Plavix (clopidogrel) or Aspirin as directed by your physician, you may minimize the chance of reocclusion.

Depends: Your age, associated risk factors like cholesterol, hypertension, diabetes and genetics, as well as diet and exercise.
