What is the remaining long-term issue associated with drug-eluting stents?Group of answer choicesInfectionThrombosisFibrosisRestenosis
Solution
The remaining long-term issue associated with drug-eluting stents is Thrombosis.
Here's why:
-
Drug-eluting stents are designed to prevent restenosis (re-narrowing of the artery after stent placement) by slowly releasing a drug that inhibits cell proliferation.
-
However, the drug also delays the healing of the artery wall where the stent is placed. This can leave the metal stent exposed to blood flow for a longer period of time, increasing the risk of blood clotting at the site, a condition known as stent thrombosis.
-
Stent thrombosis is a serious complication that can lead to heart attack or death. Therefore, patients with drug-eluting stents are typically required to take antiplatelet
