In 19 patients with unstable angina pectoris at rest, plasma levels of the platelet-derived proteins beta-thromboglobulin and platelet factor 4 were significantly elevated in blood samples obtained during or within 4 hours after episodes of angina, but were usually normal during quiescent intervals. Plasma levels of the arachidonic acid metabolite thromboxane B2 were less clearly related to ang...

Background: Coronary artery disease (CAD) is one of the most important and lethal diseases in the world. CAD represents a board spectrum of disease from silent ischemia at one end to sudden cardiac death at the other end. The middle of this spectrum consists of acute myocardial infarction (AMI) and unstable angina pectoris (UA). Recent data show that the inflammatory process plays a major r...

The mechanisms by which tissue injury after acute myocardial infarction (AMI) occurs has not been fully elucidated. Recent evidence in experimental models has suggested involvement of the complement system in microvascular and macrovascular injury subsequent to AMI. With respect to angina pectoris, whether or not the complement system is activated is not clear. The present study assessed the ro...

introduction: in this recent study in kermanshah, the cardiovascular and cerebral complications due to high normal blood pressure during a four-year follow–up period have been investigated. materials and methods: this is a descriptive follow-up study in which about 1900 citizens (over 19 years old) in kermanshah, were randomly selected in clusters and undergone measurements of blood pressure tw...

In this issue of Circulation, Renkin et all have made an intriguing observation in patients with unstable angina. They describe a subgroup of unstable angina patients with persistent inversion of precordial-lead T waves who have resting regional left ventricular wall motion abnormalities. Six months after left anterior descending angioplasty, these patients demonstrated normalization of T waves...

BACKGROUND Adiponectin, the most abundant adipocytokine of adipose tissue cells, has recently been found to be decreased in coronary artery disease (CAD). Data concerning adiponectin in different stages of CAD are rare, and it was not investigated if adiponectin levels are influenced by the severity of angina pectoris. METHODS Thus, we measured adiponectin serum levels by means of ELISA in 16...
