Patient-Specific Tailored Intervention Improves INR Time in Therapeutic Range and INR Variability in Heart Failure Patients.

Background: Many patients with heart failure need anticoagulants, including warfarin. Good control is particularly challenging in heart failure patients, with <60% of international normalized ratio (INR) measurements in the therapeutic range, thereby increasing the risk of complications. This study aimed to evaluate the effect of a patient-specific tailored intervention on anticoagulation control in patients with heart failure.
