Circulating GDF-15 levels predict future secondary manifestations of cardiovascular disease explicitly in women but not men with atherosclerosis.

Background: Elevated serum levels of growth differentiation factor-15 (GDF-15), is an established risk factor for a range of cardiovascular diseases. We aimed to evaluate the predictive value of plasma GDF-15 as a biomarker for secondary cardiovascular events (CVE) in patients with atherosclerosis undergoing carotid endarterectomy (CEA). Secondly, we determined whether plasma GDF-15 was associated with carotid plaque characteristics.

Biobanking in carotid artery disease: translation to clinical practice.

Biobanking of atherosclerotic tissue samples has contributed to our understanding of vascular occlusive disease. The careful examination of atherosclerotic plaques derived during vascular surgery or autopsies helped shape our minds in understanding the underlying substrate of arterial thrombosis. This review will outline concepts of progression of atherosclerotic disease that have been based on descriptions of human plaque pathology.

Clinical Risk Factors and Plaque Characteristics Associated with New Development of Contralateral Stenosis in Patients Undergoing Carotid Endarterectomy.

Background: Following carotid endarterectomy (CEA), cerebrovascular hemodynamic may be hampered by ipsilateral restenosis or development of contralateral stenosis. It remains to be clarified if these patients need follow-up for identifying development of contralateral stenosis. Identification of risk factors contributing to development of contralateral stenosis could allow more specific follow-up.

Clinical Relevance of Cardiac Troponin Assessment in Patients Undergoing Carotid Endarterectomy.

Objective: Myocardial infarction (MI) is a frequent complication of carotid endarterectomy (CEA), yet most events are silent. Routine post-operative monitoring of cardiac troponin was implemented to facilitate timely recognition of MI and stratify high risk patients. The aim was to evaluate the incidence of troponin elevation after CEA and its association with adverse cardiovascular events.

High reproducibility of histological characterization by whole virtual slide quantification; an example using carotid plaque specimens.

Objective: Tissue biobanks are an important source for discovery and validation studies aiming for new proteins that are causally related with disease development. There is an increasing demand for accurate and reproducible histological characterization, especially for subsequent analysis and interpretation of data in association studies. We assessed reproducibility of one semiquantative and two quantitative methods for histological tissue characterization.
