acute closure

[fistashka80]

Уважаемые Коллеги, прошу помочь с переводом выражения "acute closure" в таком контексте

Cardiovascular diseases are the most common cause of mortality and morbidity in Western countries. Percutaneous coronary intervention (PCI) has become the most frequently used form of coronary revascularization. Since the mid-1990s, stent deployment has been the gold standard to reduce the rate of acute closure and in-stent restenosis.

Признательна за помощь,
