Validation of Bleeding Risk Prediction Scores for Patients With Major Bleeding on Direct Oral Anticoagulants

The Annals of Pharmacotherapy

Abstract

Direct oral anticoagulants (DOACs) offer many benefits over vitamin K antagonists (VKAs) but still carry a significant risk of major bleeding. Bleeding risk prediction scores such as the Hypertension, Abnormal Renal/Liver Function, Stroke, Bleeding History or Predisposition, Labile International Normalized Ratio, Elderly, and Drugs/Alcohol (HAS-BLED), Hepatic or Renal Disease, Ethanol Abuse, Malignancy, Older Age, Reduced Platelet Count or Function, Re-Bleeding, Hypertension, Anemia, Genetic Factors, Excessive Fall Risk, and Stroke (HEMORR2HAGES), Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA), Registro Informatizado Enfermedad TromboEmbólica (RIETE), and CHEST scores were validated or evaluated for use with VKAs and parenteral anticoagulants, but evidence for use with DOACs is lacking. This study aims to evaluate bleeding risk prediction scores for DOAC patients presenting with major bleeding. A retrospective analysis of patients presenting from 2015 to 2018 was performed. Patients were separated into bleed and nonbleed groups. The primary objective was to assess the diagnostic accuracy of the bleeding risk prediction scores utilizing the receiver operating characteristic (ROC) curve. A total of 126 patients w...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
