New generation of stents improve prognosis after resin infarction

According to a new study, new stents that are coated with medication cause fewer complications after an acute heart attack than materials previously used. This is the conclusion reached by researchers from the University of Bern. Together with doctors from other clinics in Europe and Israel, they examined 1,100 heart attack patients and published their results in the American Heart Journal.

Patients with new stents have fewer complications in the long-term course. Physicians repeatedly discuss the suitability of certain stent types. Thanks to the new drug-coated stents, this could soon change. While in the past infections, heart problems or even re-occlusion of the coronary arteries often occurred after the insertion of a stent, the new generation of stents promises significantly fewer complications in the long-term course.

As part of the respective study, the researchers examined 1,161 patients across Europe who were treated with either a conventional uncoated or biolimus-coated stent between 2009 and 2011 due to an ST elevation infarction. Sirolimus, which is suspected of causing various side effects, has previously been used in coated stents. Therefore, the immunosuppressant biolimus was used in the new generation of stents. This drug is used particularly in medical technology due to its more biodegradable polymer.

Study confirms previous assumptions
The study confirmed the expectations for the new stents. Patients using a stent coated with biolimus showed significantly fewer complications in the long-term course. "Compared to pure metal stents, the use of biolimus stents with the biodegradable polymer resulted in a lower rate of severe adverse cardiac events in patients with ST elevation infarction who underwent primary percutaneous coronary intervention (PCI)," the researchers write. There were 50 percent fewer vasoconstrictions compared to uncoated stents. As the authors of the study report, the new stents prevented a total of 42 severe cardiovascular events related to 1,000 patients. (ag)
