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...

In this paper, the most widely used and extensively validated techniques for imaging coronary artery disease are reviewed. We describe and compare the roles of echocardiography, cardiac nuclear imaging techniques and cardiac magnetic resonance imaging. For now we see through a glass, darkly. echocardiographic imaging Two-dimensional evaluation of coronary artery disease at rest Evaluation of le...

BACKGROUND Automated function imaging (AFI) is a recently developed method of calculating the longitudinal peak systolic strains (LS) of the regional left ventricular (LV) wall using speckle tracking echocardiography and displaying them on a single bull's-eye map. The feasibility of AFI in patients with regional LV wall motion abnormalities caused by myocardial infarction (MI) was evaluated by ...

BACKGROUND Noncompaction cardiomyopathy (NCCM) is characterized by a prominent trabecular meshwork and deep intertrabecular recesses. Although systolic dysfunction is common, limited information is available on differences in wall motion of the normal compacted and noncompacted segments. The purpose of this study was to assess radial wall motion and longitudinal wall velocity in patients with N...

OBJECTIVES The purpose of this study was to compare the results and prognostic value of electron-beam computed tomography (EBCT) and exercise echocardiography. BACKGROUND Although patients with elevated coronary artery calcium scores (CACS) might be referred for exercise echocardiography, the association of EBCT CACS with wall motion score index (WMSI) is not known. METHODS Patients without...

AIMS The aim of this study was to evaluate the relationship between coronary flow reserve and the recovery of wall motion contractility in patients with recent myocardial infarction. METHODS AND RESULTS Nineteen patients (55 +/- 8 years) undergoing balloon angioplasty for recent myocardial infarction were studied. After angioplasty, coronary flow reserve was lower in the infarct-related arter...

METHODS Reinjection-g-SPECT, MIBI-g-SPECT, and three-dimensional magnetic resonance imaging (3DMRI) were conducted in 20 patients with coronary artery disease. Regional wall motion (RWM) and wall thickening (RWT) were analyzed using semiquantitative visual scoring by each g-SPECT and 3DMRI. The left ventricular end-systolic and end-diastolic volumes (EDV, ESV) and LVEF estimated by reinjectiona...

The purpose of this study was to investigate the relation of microvascular integrity and ventricular remodeling after acute myocardial infarction. Twenty-six patients with first acute anterior myocardial infarction were studied before discharge with myocardial contrast echocardiography (MCE). Opacification index (OI) and wall motion index were calculated in the left anterior descending artery t...

AIMS To determine the prevalence of left ventricular systolic dysfunction in 75-year-old men and women. METHODS AND RESULTS In a population-based random sample of 75-year-old subjects (n=433; response rate 70.1%) the left ventricular systolic function was determined using two echocardiographic methods: (1) wall motion in nine left ventricular segments was visually scored and wall motion index...
