In the monitoring of anticoagulant therapy, PT/INR is used to measure the effect of warfarin, while the aPTT measures the therapeutic effect of unfractionated heparin.

Warfarin and heparin are anticoagulant medications, or "blood thinners." They help stop your blood from clotting when it’s not necessary. Find out how the two drugs work, and how they differ.

Maintaining the INR in the therapeutic range of 2 to 3 is difficult in patients with cancer for many reasons. ... After initial treatment of VTE with unfractionated heparin or a low– ...

Unfractionated heparin infusion was used to maintain the activated partial thromboplastin time (aPTT) ratio at 2.0-3.0 in patients who had a low INR (<1.8) on day 3.

ORLANDO, Fla. — “Interestingly, clotting events only occurred in patients on heparin-free hemodialysis and warfarin,” said Graham Abra, MD, here at the Annual Dialysis Conference.&ldquo;As ...

Surgery was postponed in eight patients in the continued-warfarin group because of a supratherapeutic INR on the day of surgery (mean [±SD] INR, 3.9±0.4). In the heparin-bridging group, surgery ...

We began veno-venous ECMO, using an unfractionated heparin–coated circuit, on postadmission day 4 at 0315 after the administration of a 30 000-unit bolus of unfractionated heparin. At 1140 on the same ...

Warfarin is restarted then as well, but heparin is continued for as many days as necessary until the INR is back in the 3-3.5 range. —Peter F. Cohn, MD (99-12) From the January 10, 2007 Issue of ...

Purity concerns with unfractionated heparin—the mostly generic anticoagulant used in a wide range of cardiac surgeries and interventional procedures, as well as outside of cardiology—are nothing new.

Heparin was discontinued once target INR levels of 2.0 had been achieved. Group 2 received enoxaparin as the thromboprophylactic agent. This was started on the day of admission.
