Welcome to HCM,
If you have coronary artery disease and undergo angigraphy this we must know that if there is significant lesion in arteries it is dialated by angioplasty
and to prevent blocking that is restenosis a metal stent is placed there .
In both medicated and bare metal stent you have to take medicines to keep blood thin like asprin and clopidogrel
In general Drug eluting stents are claimed to have less chances of restenosis.
There is one more thing these medicated stents are costly and increase the cost of procedure.
If some one has multiple blocks in coronary arteries alternativel mat be CABG that is bypass surgery
The drug which used for coating is paclitaxel
Your Cardiologist will be best person to explain to you what is best for you.
You can always take a second opinion
if there is any doubt .
Please take care
