Drug-coated balloons offer alternative to permanent heart stents

Research from the University of East Anglia suggests that drug-coated balloons may serve as a safe alternative to permanent metal stents for treating coronary artery disease. A major analysis of data from over 7,800 patients across 10 randomized clinical trials indicates that drug-coated balloons perform similarly to conventional stents in preventing heart attacks and cardiovascular deaths.

Unlike traditional stents, which are tiny mesh tubes left permanently in the artery, drug-coated balloons are removed after the procedure. During inflation, the balloon releases medication into the artery wall to prevent the vessel from narrowing again. This approach aligns with the medical principle of avoiding leaving permanent foreign material in the vasculature.

While the most serious outcomes showed no meaningful difference between the two treatments, researchers noted that some patients treated with balloons might face a higher likelihood of requiring repeat procedures in the future. The SPARX study is also currently underway to directly compare these two strategies in 1,380 patients.
