EVLW was derived from mean lung density. The Global Registry of Acute Coronary Events (GRACE) score was calculated. The endpoint was in-hospital major adverse cardiovascular events (MACE), defined as all-cause mortality, acute heart failure, cardiogenic shock, resuscitated cardiac arrest, or stroke.
