Background: High-density lipoprotein (HDL) cholesterol concentration (HDL-C) is an established atheroprotective marker, in particular for coronary artery disease; however, HDL particle concentration (HDL-P) may better predict risk. The associations of HDL-C and HDL-P with ischemic stroke and myocardial infarction (MI) among women and Blacks have not been well studied. We hypothesized that HDL-P would consistently be associated with MI and stroke among women and Blacks compared with HDL-C.
Methods: We analyzed individual-level participant data in a pooled cohort of 4 large population studies without baseline atherosclerotic cardiovascular disease: DHS (Dallas Heart Study; n=2535), ARIC (Atherosclerosis Risk in Communities; n=1595), MESA …

Section of Cardiothoracic Surgery
Constrictive pericarditis (CP) is a rare end stage inflammatory disorder affecting both parietal and visceral pericardium leading to a right heart failure. Malignancy is the least common cause of CP. Anaplastic large cell lymphoma (ALCL) accounts for 10-15% of all Non-Hodgkin lymphomas in children. Very few case reports have reported ALCL that is involving the heart and only two have been published involving pericardium but all were managed medically. We present an interesting case of an 11 year old child who presented with an effusive CP that required urgent Pericardiectomy for managing right heart failure. His histopathology was positive for …
