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). They are used in a medical procedure called percutaneous ...
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 ...
As with any procedure involving the heart, complications can sometimes, though rarely, cause death. The mortality rate during angioplasty is 1.2%. [17] Sometimes chest pain can occur during angioplasty because the balloon briefly blocks off the blood supply to the heart. The risk of complications is higher in: [18] People aged 65 and older
Disadvantages include a high rate of complications, such as deep sternal wound infections, in some subgroups of patients—mainly obese and diabetic ones. The left radial artery and left gastroepiploic artery can be also used. Long-term patency is influenced by the type of artery used and intrinsic factors of the cardiac arterial circulation. [41]
It is used to open and widen clogged heart arteries and then dissolves or is absorbed by the body. Unlike traditional metal stents, bioresorbable stents can restore normal vessel function, avoid long-term complications, and enable natural reconstruction of the arterial wall.
In this study, angioplasty was associated with less short term morbidity compared with bypass surgery; however, long term outcomes favor bypass surgery. [ 7 ] Based on this study, the ACCF/AHA [ clarification needed ] guidelines recommend balloon angioplasty only for patients with a life expectancy of 2 years or less or those who do not have an ...
