I have under gone angioplasty in Mar.07 stunting in right arteries. I am 56 yrs male. Presently I am taking 2.5mg Ramipril, 25 mg metaprolol after breakfast and 10mg Astrovastin with 75mg ecospirin at bed time. These medicines are being taken regularly. I am keeping good health without any sign of my previous illness. I take moderate exercise in routine and do job normally. I have never been detected any blood pressure and my blood samples (like lipid profiles) are well within the specified limits. I want to know if medicines can be stopped or reduced in its frequency. Please advise.
