Drug-eluting stents are coated with medication that is slowly released (eluted) to help prevent the growth of scar tissue in the artery lining. This helps theartery remain smooth and open, ensuring good blood flow.

How do I know if my stent is blocked? Sometimes heartproblems return after a stent procedure. If that happens, you usually have symptoms—like chest pain, fatigue, or shortness of breath. If you do have symptoms, a stress test can help your doctor see what's going on. It can show if a blockage has returned or if there's a new blockage.

What percent of blockage requires a stent? By clinical guidelines, an artery should be clogged at least 70 percent before a stent should be placed, Resar said. “A 50 percent blockage doesn't need to be stented,” he said.

What is the price of stent? As per the new prices notified by the National Pharmaceutical Pricing Authority (NPPA), a bare metal stent (BMS) would now cost Rs 8,261, while the drug eluting stent (DES) will cost Rs 30,080. BMS used to cost as much as Rs 45,000 and DES Rs 1.21 lakh prior to the imposition of the price cap in February2017.
