New Drug Stents Help Keep Heart Artery Open. Aug. 11, 2004 -- A new study shows that drug-coated stents designed to prevent repeat blockage of heart arteries apparently do just that. But Canadian researchers say there is no evidence that they actually prevent heart attack or death. Stents are small, wire-mesh tubes placed in a heart artery after balloon angioplasty, a procedure to reopen the artery when it's blocked or narrowed.
The aorta is the largest artery and is connected directly to the heart. When blood flows from the heart and is forced into the arteries, they must expand to accept the blood and then contract to squeeze the blood into the veins as the heart relaxes between beats. This means that arteries need to be elastic to keep expanding and contracting. When the heart relaxes, it is the job of the arteries to maintain blood pressure and keep it moving forward. Arteries maintain the minimum needs of blood pressure. If they did not work, blood pressure would be closer to 120/0 instead of 120/80.
