Force patterns of hypoxic myocardium applied to oxygenated muscle preparations: Comparison with effects of regional ischemia on the contraction of non-ischemic myocardium
Objective: To examine the basis for local wall motion abnormalities commonly seen in patients with ischemic heart disease, computer-controlled isolated muscle studies were carried out. Methods: Force patterns of physiologically ...
Clinical features and prognosis of acute myocardial infarction among patients aged 80 years or older Infarto agudo al miocardio en pacientes de 80 y más años. Evolución hospitalaria y seguimiento
Background: Subjects older than 80 years have more complicated acute myocardial infarctions and are subjected to less reperfusion procedures. Aim: To describe the hospital evolution and follow up of patients older than 80 ...
Adherence to Guidelines for Acute Myocardial Infarction with ST Segment Elevation in a University Hospital of 4th level in Bogota (Colombia) between January 2008 and July 2011Adherencia a guías de infarto agudo de miocardio con elevación de segmento ST en un Hospital Universitario de nivel IV en Bogotá, Colombia, en periodos comprendidos entre enero de 2008 y julio de 2011
Calpain translocation and activation as pharmacological targets during myocardial ischemia/reperfusion
Calpains contribute to reperfusion-induced myocardial cell death. However, it remains controversial whether its activation occurs during ischemia or reperfusion. We investigated the regulation and time-course of calpain ...
Selective cyclooxygenase-2 inhibition protects against myocardial damage in experimental acute ischemia
(Faculdade de Medicina / USP, 2009)
BACKGROUND: Acute myocardial infarction is associated with tissue inflammation. Early coronary reperfusion clearly improves the outcome but may help propagate the inflammatory response and enhance tissue damage. Cyclooxygenase-2 ...
Cellular mechanisms against ischemia reperfusion injury induced by the use of anesthetic pharmacological agents
Ischemia–reperfusion (IR) cycle in the myocardium is associated with activation of an injurious cascade, thus leading to new myocardial challenges, which account for up to 50% of infarct size. Some evidence implicates ...
