I had my coronary angioplasty one year back. i am on clopidogrel 70mg bd, atrovastation 40 mg od, metroprolol 25 od and aspirin 150mg od. should i reduce my medication?

Probably not: It depends on the type of stent used. If it was a coated stent, you should stick with your current program (i assume the clopidogrel is 75, not 70). If it was a bare metal stent, after a year you might ask your doctor about going with Aspirin alone.

Reduce medication?: Your interist or cardiologist are the best qualified professionals to accurately answer that question for you. They will be most intimately in touch with your past and current medical condition.

Excellent insight: After stenting may will stay on Plavix (clopidogrel) for the duration aspirin 81 likely forever some statin likely but check cholesterol and may be able to adjust beta blocker may be weaned if no hypertension or tachycardia.
