Moderate hyperhomocysteinaemia is considered as an independent risk marker for cardiovascular disease and stroke. Earlier, increased homocysteine production was detected in stimulated immunocompetent cells in vitro, and several markers of inflammation like neopterin or C-reactive protein (CRP) were demonstrated as significant indicators of cardiovascular risk. The relationship between coronary artery ...

Coronary atherosclerosis is a chronic inflammatory disease, but different inflammatory biomarkers may reflect different phases of atherosclerotic plaque evolution. We aimed at assessing the role of eosinophil cationic protein (ECP), a sensitive marker of eosinophil activation, and C-reactive protein (CRP) in coronary artery disease (CAD). Consecutive anginal patients with angiographic ...

Bidimensional echocardiography is a non-invasive imaging diagnostic method that effectively assesses global and regional left ventricular diastolic function. Disruption of left ventricular diastolic function in systemic lupus erythematosus (SLE) is almost always clinically silent, suggesting a subclinical diastolic dysfunction. We evaluate in the the present study the different echocardiographic techniques ...
