Assessing Myocardial Perfusion after Myocardial Infarction
A 63-year-old man presented to our accident and emergency department with a 2-hour history of crushing central chest pain, excessive sweating, and diffi culty in breathing. Past history included non-insulindependent diabetes mellitus controlled by oral hypoglycaemic agents. On examination, he appeared unwell, with pulse of 94 beats per minute, blood pressure of 124/68 mm Hg, and respiratory rat...
متن کاملEvaluation of myocardial perfusion and function after kidney transplantation by Gated SPECT myocardial perfusion scintigraphy
Introduction: The aim of this study was to evaluate the effect of successful kidney transplantation (KT) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-SPECT) in patients suffering from end-stage renal disease. ...
متن کامل[Changes in myocardial function and perfusion after acute myocardial infarction].
Rev Esp Cardiol 2003;56(5):433-5 433 Ligation of a coronary artery causes myocardial necrosis. It has been shown in experimental animals1 that the size of the necrotic scar is directly proportional to the time elapsed between ligation and reperfusion. Early reperfusion not only reduces the size of the infarct, but also protects against ventricular dilatation. Although delayed reperfusion is una...
متن کاملMyocardial perfusion SPECT: Perfusion quantification
Different software tools for quantification of myocardial perfusion SPECT (MPS) studies are routinely used. Several perfusion parameters can be computed automatically. Interpretation of the MPS should start with visual inspection of the rotating planar images, visual analysis of reconstructed SPECT slices and then quantitative analysis to confirm the visual impression. Quantification should be...
متن کاملnon invasive assessment of myocardial perfusion after first myocardial infarction with transthoracic echocardiography
background: standard methods for the measurement of myocardial perfusion are invasive and require cardiac catheterization or the use of radioisotope dyes. the coronary sinus blood flow (csbf) is an appropriate criterion for the efficacy of myocardial perfusion. this study sought to measure csbf via transthoracic echocardiography (tte) in patients with acute myocardial infarction (ami) and to as...
