introduction: chest x–ray is one of the most common method of imaging. cardio thoracic ratio ( ctr ) is one of the parameters of chest x–ray that is used for determining cardiac enlargement. echocardiography as compared to chest x–ray is expensive and all centers dont have it, but it can determine heart size, valvular diseases, ejection fraction, left ventricular hypertrophy (lvh), pericardial ...

background beta-2 microglobulin (b2m) is considered as a surrogate marker for middle molecule uremic toxins and a key component in dialysis-related amyloidosis. however, few studies have evaluated role of b2m in patients with chronic kidney disease (ckd). objectives the purpose of this study was to evaluate the association of plasma b2m level with some metabolic and cardiac performance factors ...

This study examined the early neurohumoral events in the progression of congestive heart failure (CHF) after myocardial infarction (MI) in rats. Immediately after MI was induced by coronary artery ligation, rats had severely depressed left ventricular systolic function and increased left ventricular end-diastolic volume (LVEDV). Both left ventricular function and the neurohumoral indicators of ...

Six patients underwent cardiac catheterization before and after occurrence of a myocardial infarction. Results from the two procedures allowed the quantitation of changes in coronary artery anatomy and left ventricular performance associated with myocardial infarction. Left ventricular biplane or single plane angiography and selective coronary angiography were used to evaluate coronary artery a...
