Lp(a) is a carrier of oxidized phospholipids (OxPL) that contribute to its atherothrombotic properties. The current objective is to study the relationship of Lp(a) and OxPL biomarkers with TCS in patients with high-risk vascular diseases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>In a subanalysis of the ongoing MBRACE trial (Multidisciplinary Approach to Reduce Cardiovascular Health Disparities in the Baltimore Racial Minority Communities), we studied Lp(a), OxPL biomarkers, and TCS in healthy subjects (n=17) and in patients with cardiovascular disease undergoing percutaneous intervention (multivessel coronary artery disease [n=60], myocardial infarction [n=86], and ischemic stroke [n=28]). Lp(a), OxPL-apoB, OxPL-apo(a), OxPL-plasminogen (OxPL-PLG), and total plasminogen were measured using enzyme-linked immunoassays. High Lp(a) was defined as \u2265125 nmol\/L.
