Intima media thickness of the common carotid artery in vascular surgery patients: A predictor of postoperative cardiovascular events
.
Results: In total, 30-day events and long-term cardiovascular mortality were noted in 122 (24%) and 81 (16%) patients, respectively. The optimal predictive value of CCA-IMT, using receiver-operating characteristic curve analysis, for the prediction of CV events was calculated to be 1.25 mm (sensitivity 70%, specificity 80%). An increased CCA-IMT was independently associated with 30-day CV events (OR 2.20, 95% CI 1.38-3.52) and long-term CV mortality (HR 6.88, 95% CI 4.11-11.50), respectively.

Conclusions: This study shows that an increased CCA-IMT has prognostic value in vascular surgery patients to predict 30-day CV events and long-term CV mortality, incremental to the RCR index.

Skin Tc was determined noninvasively using the Cholesterol 1,2,3 system (International Medical Innovations, Toronto, Ontario, Canada).2-4 The hypothenar eminence of each hand was cleansed with alcohol and allowed to dry. In a die-cut well foam template affixed to the palm, a drop of solution containing a synthetic digitonin-copolymer-horseradish peroxidase conjugate was applied to the prepared area and incubated for 1 minute. The area was blotted and an indicator solution containing a horseradish peroxidase substrate that induces a blue color change was applied in the well. Positive and negative control well samples were applied concurrently on the same skin surface. Skin cholesterol levels were quantified based on color change. Hue development was measured by reflectance using a handheld spectrophotometer (MD22 Spectrophotometer; X-Rite, Inc, Grandville, MI), which was interfaced with a computer, and the resulting change in hue was numerically reported in units (U). Assay validity was assessed by visual interpretation of control wells.

Depois fizeram a análise das carótidas de modo automático .(CIMT Screen, Camtronics Medical Systems)

Muito interessante. Qualquer método que analise doenças ou variações metabólicas se correlaciona com a espessura das carótidas. Estamos falando da idade vascular?
