INTRODUCTION Acute kidney injury (AKI) after cardiac surgery increases length of hospital stay and in-hospital mortality. A significant number of patients undergoing cardiac surgical procedures require perioperative intra-aortic balloon pump (IABP) support. Use of an IABP has been linked to an increased incidence of perioperative renal dysfunction and death. This might be due to dislodgement of...

AIMS To determine whether the presence and severity of aortic atheroma predict long-term all-cause mortality among patients undergoing cardiac surgery. METHODS AND RESULTS We followed 8,581 patients who underwent cardiac surgery and had routine intraoperative transoesophageal echocardiography for 2.8 years (range 0.06-6.0 years). Data regarding multiple potential confounders were prospectivel...

OBJECTIVE Accumulation of cholesterol in foam cells of atheroma plaques depends on the balance between uptake and efflux of cholesterol. It may also depend on proteins surrounding lipid droplets, adipophilin, and perilipins. They favor triglyceride storage in adipocytes and could play a similar role for cholesterol in atheroma. METHODS AND RESULTS We measured in human atheroma and nearby macr...

BACKGROUND AND PURPOSE Aortic atheroma is an independent risk factor for stroke and undergoes temporal progression. Clinical and risk factor associations of such progression are unknown. Hyperhomocysteinemia has been linked with atherosclerosis, including that in the cerebral vasculature. This study investigated associations between elevated homocysteine levels and other stroke vascular risk fa...

BACKGROUND Common carotid intima media thickness (CIMT) and ankle brachial pressure index (ABPI) are used as surrogate marker of atherosclerosis, and have been shown to correlate with arterial stiffness, however their correlation with global atherosclerotic burden has not been previously assessed. We compare CIMT and ABPI with atheroma burden as measured by whole body magnetic resonance angiogr...
