Baron Cardiology Group offers a clinic devoted to patients who are taking the drug Coumadin (also known as warfarin). Coumadin is an anticoagulant medication prescribed for patients to reduce the risk of their body forming a blood clot, which can lead to a heart attack, stroke or even death. Patients enrolled in the Coumadin Clinic must have frequent blood tests (PT/INR) to assure that the time it takes their blood to clot remains in the desired range.
