It is used in a procedure called percutaneous coronary intervention (PCI).<unk> s are now used in more than 90% of PCI procedures.<unk> s reduce angina (chest pain) and have been shown to improve survivability and decrease adverse events in an acute myocardial infarction. Similar<unk> s and procedures are used in non-coronary vessels (e.g., in the legs in peripheral artery disease).
