Boston Scientific floats new data on balloon to fight heart attacks
In more devices news, Lizzy reports on new data from Boston Scientific suggesting that a drug-coated balloon could reduce the risk of heart attack in people with complications from stents.
The treatment is meant for patients whose arteries have shrunk even after receiving a stent to open up the clogged vessel. Stent placement sometimes causes scar tissue to build up and prevent blood flow. Cardiologists can use drug-eluting stents to prevent scar formation, but the condition still occurs in around 10% of patients who have those stents implanted. The disorder, called in-stent restenosis, can cause chest pain and increase risk of heart attack.
Partial data presented by investigators at the Transcatheter Cardiovascular Therapeutics conference suggests that patients in this group who were implanted with balloons coated with a chemotherapy called paclitaxel were less likely to have heart attacks than those implanted with control balloons. The data is incomplete now but may be supportive of an eventual filing with the Food and Drug Administration. An outside researcher, however, said they would like to see longer term outcome data before passing judgment.
