A coronary stent is a tube-shaped device placed in the coronary arteries that supply blood to the heart, to keep the arteries open in patients suffering from coronary heart disease. The vast majority of stents used in modern interventional cardiology are drug-eluting stents (DES).
Plaque build-up often doesn’t cause symptoms, but it can block blood flow to vital organs like your heart. Coronary artery disease occurs when atherosclerosis affects the arteries supplying ...
Symptoms may also suggest or signal restenosis, but this should be confirmed by imaging. For instance, a coronary stent patient who develops restenosis may experience recurrent chest pain or have a minor or major heart attack (myocardial infarction), though they may not report it. This is why it is important that a patient comply with follow-up ...
Patients must still be carefully selected for surgery or stenting in order to reduce the risks related to the procedure and ensure the long-term benefit after such intervention. Other short-term complications might include bleeding, infection and heart problems such as myocardial infarction related to anesthesia.
The report, published in the scientific journal Circulation, looked at more than 7,500 patients with acute coronary syndrome: a term that describes a variety of heart conditions — including ...
A dual therapy stent is a coronary artery stent that combines the technology of an antibody-coated stent and a drug-eluting stent. [1] Currently, second-generation drug-eluting stents require long-term use of dual-antiplatelet therapy , which increases the risk of major bleeding occurrences in patients. [ 2 ]
Percutaneous coronary intervention (PCI) is a minimally invasive non-surgical procedure used to treat narrowing of the coronary arteries of the heart found in coronary artery disease. [2] The procedure is used to place and deploy coronary stents , a permanent wire-meshed tube, to open narrowed coronary arteries.
The catheter site is checked for bleeding and swelling and the heart rate and blood pressure are monitored to detect late rupture and hemorrhage. [26] Post-procedure protocol also involves monitoring urinary output, cardiac symptoms, pain and other signs of systemic problems. [26]
