Coating stents with vitamin C could cut the risk of clotting, according to research published in the ACS journal Langmuir.
Stents are inserted into blood vessels in individuals who have experienced heart attacks or chest pain due to blocked arteries.
According to the research, coating these with vitamin C could lower the risk of late stent thrombosis (LST) in patients. This potentially fatal complication occurs when clots form and re-block the arteries.
The drugs on the stents are helpful for some issues, but it is thought they could be the cause of other problems. These compounds prevent the growth of smooth muscle cells, preventing them from blocking the area in question. However, they can also stop the growth of endothelial cells that are very important when it comes to preventing LST.
According to researchers Eagappanath Thiruppathi and Gopinath Mani, vitamin C could provide a solution, as it may be a good alternative or addition to the drugs already used to coat the stents.
It was noted that the vitamin inhibits the growth of smooth muscle cells but also encourages endothelial cells.
