BARC • • Type 0: No evidence of bleeding. Type 1: Bleeding that is not actionable and does not cause the patient to seek unscheduled performance of studies, hospitalization, or treatment by a health care professional. Examples include, but are not limited to, bruising, hematoma, nosebleeds, or hemorrhoidal bleeding for which the patient does not seek medical attention. Type I bleeding may include episodes that lead to discontinuation of medications by the patient because of bleeding without visiting a health care provider. Circulation 2011
BARC • Type 2: Any clinically overt sign of hemorrhage (e. g. , more bleeding than would be expected for a clinical circumstance; including bleeding found by imaging alone) that is actionable, but does not meet criteria for Type 3 BARC bleeding, • The bleeding must require diagnostic studies, hospitalization or treatment by a health care professional. In particular, the bleeding must meet at least one of the following criteria: ¡ ¡ ¡ 1) Requiring intervention: defined as a health care professional -guided medical treatment or percutaneous intervention to stop or treat bleeding, including temporarily or permanently discontinuing a medication or study drug. 2) Leading to hospitalization or an increased level of care: defined as leading to or prolonging hospitalization or transfer to a hospital unit capable of providing a higher level of care; or 3) Prompting evaluation: defined as leading to an unscheduled visit to a healthcare professional resulting in diagnostic testing (laboratory or imaging). Circulation 2011
BARC • Type 3: Clinical, laboratory, and/or imaging evidence of bleeding with specific healthcare provider responses, as listed below: • a. BARC Type 3 a Bleeding • Any transfusion with overt bleeding; Overt bleeding plus hemoglobin drop ≥ 3 to <5 g/d. L* (provided hemoglobin drop is related to bleeding) • • b. BARC Type 3 b Bleeding Overt bleeding plus hemoglobin drop ≥ 5 g/d. L* (provided hemoglobin drop is related to bleed), Cardiac tamponade, Bleeding requiring surgical intervention for control (excluding dental/nasal/skin/hemorrhoid), Bleeding requiring intravenous vasoactive drugs • c. BARC Type 3 c Bleeding • Intracranial hemorrhage (does not include microbleeds or hemorrhagic transformation; does include intraspinal). Intraocular bleed compromising vision Circulation 2011 In-press
BARC Type 4: CABG-Related Bleeding. • Perioperative intracranial bleeding within 48 • • hours Reoperation following closure of sternotomy for the purpose of controlling bleeding Transfusion of ≥ 5 units of whole blood or packed red blood cells within a 48 hour period* Chest tube output ≥ 2 L within a 24 hour period. Notes: If a CABG-related bleed is not adjudicated as at least a Type 3 severity event, it will be classified as ‘not a bleeding event. ’ If a bleeding event occurs with a clear temporal relationship to CABG (i. e. within a 48 hour timeframe) but does not meet Type 4 severity criteria, it will be classified as ‘not a bleeding event’. * only allogenic transfusions are considered as transfusions for CABG-related bleeds Circulation 2011
BARC Type 5: Fatal Bleeding. • Fatal bleeding is bleeding that directly causes • • death with no other explainable cause. BARC Fatal Bleeding is categorized as either definite or probable as follows: a) Probable fatal bleeding (Type 5 a) is bleeding that is clinically suspicious as the cause of death, but the bleeding is not directly observed and there is no autopsy or confirmatory imaging. b) Definite fatal bleeding (Type 5 b) is bleeding that is directly observed (either by clinical specimen – blood, emesis, stool, etc. - or by imaging) or confirmed on autopsy.

Conclusions v Pharmacologic treatment of patients with CVD has improved over the years to decrease ischemic and bleeding complications v As most drugs which ↓ ischemia also ↑ bleeding, the offsetting impact of adverse ischemic and hemorrhagic events must be carefully examined v The net balance of ischemia and bleeding may vary tremendously with the risk profile of the individual pt for each complication, and the follow-up duration v Models are needed to assess a patient’s risk for bleeding as well as ischemic complications to further enhance treatment of the patients with therapies that are efficacious and also safe.
