One of the important principles of post PCI care is, we need to be very careful till the metal struts are fully endothelialised . This is of vital importance as improper endothelialisation is a powerful trigger and nidus for a imminent thrombosis and acute coronary syndrome.
It is a billion dollor irony , the much hyped DES does exactly what we don’t want ! and still it’s usage is increasing world wide . The drugs (Anti cancer agents) which coat the DES are the villains as it prevents the metal struts from being endothelialised and keep the metal surface raw and vulnerable , while the much maligned bare metal stents allow this natural endothelialisation process without any interruption ! So right now it is mandatory to administer dual antiplatelet agents life long( life of the stent !) for the patients with DES.
Just look , at the following image of a stent in vitro at 30 days follow up

nice pictures.if BMS scores over DES in all aspects,then why all cardiologists prefer DES as the first line treatment.Why so much confusion among cardiologists at the cost of patients suffering? sir, will we return to an era of POBA again ?Does all new discoveries after several years of research end nowhere?
