Preventing pulmonary embolism with vena caval filters
July 1st 2007* Vena caval interruption has been used in the treatment of deep venous thrombosis (DVT) to prevent PE since the early 1970s. Filter placement has been increasing in the past decade. We estimate that filters are placed in more than 0.2% of all Medicare recipients annually.
Lipoprotein(a): A New Treatment Target?
July 1st 2007Lp(a) is a fascinating variant of low-density lipoprotein (LDL). It is basically an LDL molecule that has been modified by the covalent addition of apoprotein(a). Elevated levels of Lp(a) correlate with increased risk of acute coronary syndromes, cerebrovascular accident, peripheral arterial disease, and coronary mortality. This Q&A session answers some curiosities about Lipoprotein(a).
Strategies for evaluating patients with acute pulmonary embolism
