OBJECTIVE To study the relation between cardiac systolic activity and cardiac cycle dependent variation in the ultrasound signal arising from within the myocardium. DESIGN Regional echo amplitude was used as a measure of the myocardial ultrasound signal. Relative echo amplitude values were assigned by standardising echo gain using the posterior parietal pericardium as an in-vivo calibration. ...

BACKGROUND Real-time myocardial contrast echocardiography permits the detection of myocardial perfusion abnormalities during stress echocardiography, which may improve the accuracy of the test in detecting coronary artery stenoses. We hypothesized that this technique could be used after a bolus injection of the selective A2A receptor agonist regadenoson to rapidly and safely detect coronary art...

Database searching is the technique of choice for shotgun proteomics, and to date much research effort has been spent on improving its effectiveness. However, database searching faces a serious challenge of efficiency, considering the large numbers of mass spectra and the ever fast increase in peptide databases resulting from genome translations, enzymatic digestions, and post-translational mod...

postsystolic motion or shortening predict recovery of myocardial function after primary percutanous coronary intervention?. J Am Soc Echocardiogr 2007;20: 505–11. 14. Lim P, Pasquet A, Gerber B, D’Hondt AM, Vancraeynest D, Gueret P et al. Is postsystolic shortening a marker of viability in chronic left ventricular ischemic dysfunction? Comparison with late enhancement contrast magnetic resonanc...

AIMS We sought to investigate whether combining left ventricular (LV) volumes, regional wall motion abnormalities, and scar tissue extent obtained by cardiac magnetic resonance (CMR) improves risk stratification of patients with previous myocardial infarction (MI). METHODS AND RESULTS In 231 consecutive patients (age 64 ± 11 years, males 89%) with previous MI, we quantified LV volumes and reg...

INTRODUCTION Cardiovascular disease and heart failure are common in dialysis patients. Recurrent subclinical myocardial ischemia is an important event which may lead to the heart failure. We examined whether this phenomenon occurs secondary to the intradialytic hypotension in hemodialysis patients. MATERIALS AND METHODS Twelve patients prone to intradialytic hypotension who had been on mainte...

OBJECTIVES To determine whether quantitative wall motion assessment by CMR myocardial feature tracking (CMR-FT) would reduce the impact of observer experience as compared to visual analysis in patients with ischemic cardiomyopathy (ICM). METHODS 15 consecutive patients with ICM referred for assessment of hibernating myocardium were studied at 3 Tesla using SSFP cine images at rest and during ...

Background: Surgical management of posttraumatic elbow stiffness has been reported with poor outcome following treatment. Elbow arthrolysis done in any age group and even very old cases yield good results. The goal of our study was to assess the outcome in improvement of the range of motion of the elbow after surgical release by a tailor-made approach to yield good result.Materials and Methods:...
