Components of a drug eluting stent (DES)
Brief Review
Abstract: Drug eluting stents have stent struts, polymer used to anchor the drug and the drug itself. Polymer coating of the drug eluting stent (DES) reduces the expandability of the DES.
Drug eluting stents were introduced to reduce the chance of restenosis which was common with bare metal stents. Neointimal proliferation is the important cause of restenosis of bare metal stents. Hence drugs which can suppress neointimal proliferation, basically antineoplastic antibiotics, have been used to reduce restenosis in drug eluting stents. The important components of a drug eluting stent are:
Stent platform: Sten...

Kounis Syndrome
Kounis syndrome is an acute coronary syndrome associated with a hypersensitivity / anaphylactic phenomenon. Three types of Kounis syndrome have been described:
Type I: Anaphyactic reaction causing coronary spasm in normal or near normal coronary arteries and may progress to myocardial infarction
Type II: Anaphylactic reaction combined with a pre-existing atheromatous coronary lesion can result in acute myocardial infarction
Type III: Hypersensitivity to an intracoronary stent resulting in severe stent thrombosis
Thus anaphylaxis can cause coronary spasm leading to acute myocardial infarction and life threatening c...
