Anticoagulation clinic

Entrance to the Anticoagulation Clinic at Community Heart and Vascular HospitalAt the Anticoagulation Clinic at Community Heart and Vascular Hospital, we help cardiovascular patients manage their anticoagulation (blood thinner medication) therapy.

Anticoagulation medication is prescribed to help prevent or treat harmful blood clots in the veins, arteries, lungs or heart. An anticoagulant is often prescribed to help prevent and treat blood clots in the legs and lungs, atrial fibrillation, and after heart-valve replacement surgery. Because everyone responds differently to anticoagulants, it is necessary to monitor your response to the medication carefully.

At the clinic, we will perform a simple finger stick to obtain a small drop of blood to be tested. This test measures your prothrombin time (PT) which is converted to an international normalized ratio (INR). This result helps us to see how fast your blood is clotting and therefore recommend the correct dose of anticoagulation medication, such as warfarin or coumadin.

What factors could affect your PT/INR?

  • Sickness
  • Diet
  • Other medications, vitamins or herbal supplements
  • Physical activities
  • Missed doses of warfarin, or failure to take it as prescribed

Important facts about anticoagulation therapy

  • You will bruise easier when using an anticoagulant, however, if you notice excessive bruising (a lot more than normal), please contact the clinic.
  • If your PT/INR level becomes too high, you are at risk for bleeding.
  • If your PT/INR level becomes too low, you are at risk for developing a blood clot.

Contact us if you experience any of the following symptoms:

  • Severe or sudden headache, dizziness, or weakness
  • Bleeding from a cut that will not stop
  • Nosebleeds (a small amount of pinkish mucus is normal)
  • Bleeding gums while brushing your teeth
