HI..during angioplasty( PTCA
) two types of stents are used. first BMS( bare metal stent), second is DES( drug coated stent). in both of stents Aspirin
is given life long, initially 162 to 325 mg for 1 to 6 months depending upon stent type followed by 75 to 162 mg lifelong..
For pts with DES clopidogrel
is recommended in doses of 75 mg per day for atleast one year and after that can be continued depending upon risk factors or physicians choice( some cardiologist also give double dose of clopidogrel for 2 to 3 initial months).
for BMS clopidogrel 75 mg is recommended for minimum 1 month and ideally for 1 year
