Microcirculatory resistance index based on a single angiographic view predicts long-term prognosis following rotational atherectomy in patients with acute coronary syndrome

Abstract Background To explore the long-term predictive value of the angiographic microcirculatory resistance (AMR) index for patients with acute coronary syndrome (ACS) undergoing rotational atherectomy (RA). Methods A total of 344 ACS patients undergoing RA during percutaneous coronary interventio...
