[Perioperative control of vitamin K antagonists in elective surgery].

Anti-coagulated patients who undergo elective surgery require temporary interruption of vitamin K antagonists. The aim of this study was to evaluate the incidence of thromboembolic events and bleeding complications in anti-coagulated patients undergoing elective invasive procedures by using an institutional management protocol. This was a descriptive study with prospective follow-up that included patients over 18 year old anti-coagulated with vitamin K antagonists, undergoing elective surgery.

Effects of Atorvastatin on Oxidative Stress Biomarkers and Mitochondrial Morphofunctionality in Hyperfibrinogenemia-Induced Atherogenesis.

Relationship between hyperfibrinogenemia (HF), oxidative stress, and atherogenesis was established. Effect of atorvastatin (Ator) was assessed. Wistar male (6 months) rats were studied: Ctr, control, without HF induction; Ctr-Ator, without HF treated with atorvastatin; AI, atherogenesis induced, and AI-Ator, atherogenesis induced and treated with atorvastatin.
