Defining the Optimal Activated Clotting Time During Percutaneous Coronary Intervention
Background—Unfractionated heparin has been the primary anticoagulant therapy for percutaneous coronary intervention for .20 years. Despite the availability of rapid “point of care” testing, little clinical data defining the optimal level of anticoagulation are available. Furthermore, recent reports have advocated the use of low-dose heparin regimens in the absence of large-scale, well-conducted...

متن کاملActivated Clotting Times and Cardiopulmonary Bypass 1: The Effect of Hemodilution and Hypothermia upon Activated Clotting Time
Anticoagulation during extracorporeal circulation is achieved by a variety of protocols. 1 •2•3•4 ·5 Of those routinely used, the most convenient method of heparin management utilized the activated clotting time (ACT) and dose-response curve (DRC) as described by Bull.6 It has become apparent, however, that a number of factors other than heparin concentration influence the ACT. This study was d...
متن کاملMeasured by Activated Clotting Time and Factor Xa Inhibition
The effect of hypothermia on heparin anticoagulation was studied using (siliceous earth) activated clotting time (ACT) measured by the modified Hattersley technique and anti-factor Xa assay measured by the modified Teien technique during cardiopulmonary bypass (CPB). Seventeen adult patients with normal blood coagulation function undergoing their first time coronary artery bypass grafting surge...
متن کاملOptimal activated clotting time during percutaneous coronary intervention.
Percutaneous Coronary Intervention To the Editor: We read with interest the article by Chew et al1 in the February 20, 2001, issue of Circulation, but we were disappointed that such eminent investigators could confuse associations arising from heterogeneous pooled data with hard evidence on which scientific conclusions can be drawn. In their Conclusions, they state that their meta-analysis “. ....
