Mr. D. needs to be assessed for presence of anemia and platelet abnormality prior to anticoagulation to establish a baseline in case he should develop bleeding complications or platelet abnormality as a reaction to heparinization. Useful to evaluate for myocardial infarction, arrhythmia, or other cardiac causes of symptoms, a. A venous embolus is a detached blood clot or thrombus that travels through the venous circulation, generally lodging in a more proximal vessel or site distant from the original source.
