Perceived or Calculated Bleeding Risk and Their Relation With Dual Antiplatelet Therapy Duration in Patients Undergoing Percutaneous Coronary Intervention

The High Bleeding Risk Patient with Coronary Artery Disease

Out-of-hospital bleeding is a common complication after percutaneous coronary intervention (PCI) due to the concomitant need for dual antiplatelet therapy. A significant proportion of patients undergoing PCI carry specific clinical characteristics posing them at high bleeding risk (HBR), increasing the risk of hemorrhagic complications secondary to antithrombotic therapy. Identifying patients at HBR and adjust antithrombotic therapy accordingly to optimize treatment benefits and risk is a challenge of modern cardiology. Recently, multiple definitions and tools have been provided to help clinicians with prognostic stratification and treatment decision making in this subgroup.
