Currently approximately one million stents are implanted annually worldwide. The balloon angioplasty augmented with the use of the stent has become the preferred treatment for atherosclerosis. However, the stent has not completely done away with restenosis after angioplasty, and improved procedures continue to be sought.
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).
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 ]
For some high-risk cardiovascular patients with stents, the often-recommended practice of prolonged taking of aspirin might be ineffective, and in some cases, even harmful, a new study found.
Dilated cardiomyopathy is one of the main causes of heart failure. It occurs in about 1 in 2,500 people. Treatment for dilated cardiomyopathy may involve taking medications or surgery to reduce ...
During a balloon angioplasty, the stent is inserted into the artery to provide a "scaffold" to open the artery. An anti-rejection-type medication, sirolimus , helps to limit the overgrowth of normal cells while the artery heals which reduces the chance of re-blockage in the treated area known as restenosis , and reduces the chances that another ...
Stent technology improved rapidly, and in 1989 the Palmaz-Schatz balloon-expandable intracoronary stent was developed. [24] [25] Initial results with the Palmaz-Schatz stents were excellent when compared to balloon angioplasty, with a significantly lower incidence of abrupt closure and peri-procedure heart attack.
