Diagnostic accuracy of global longitudinal strain in prediction of severity and extent of coronary artery stenosis in patients with acute coronary syndrome.

Background: 2 D Speckle tracking echocardiography (STE) is a non-invasive, angle-independent, semiautomatic and objective technique that quantitatively assesses global and regional longitudinal systolic strain and provides a single bull's eye map for segmental wall strain of the left ventricle.

Objectives: assessment of the accuracy of global longitudinal strain (GLS) using STE in the detection of resting myocardial ischaemia and its severity compared with visual assessment of wall motion score index by conventional 2 D echo.

Patients And Methods: 100 patients who presented with ACS were included.

B-type Natriuretic Peptide as an Index of Symptoms and Severity of Chronic Rheumatic Mitral Regurgitation.

Background: The most common causes of severe mitral regurgitation (MR) in developing countries are rheumatic heart disease. The plasma level of B-type natriuretic peptide (BNP) is known to increase with left ventricular (LV) dysfunction.

Aim Of The Work: To study BNP level as an index of symptoms and severity of chronic rheumatic MR.
