BACKGROUND Whether left ventricular function can be assessed accurately by gated single photon emission computed tomography (SPECT) in patients with myocardial infarction and severe perfusion defects is not well known. METHODS AND RESULTS Twenty-five patients with an acute myocardial infarction underwent 99mTc-labeled tetrofosmin (99mTc-tetrofosmin) gated SPECT and cine magnetic resonance ima...

The aim of this study was to determine the feasibility and accuracy of wall motion score index (WMSI) and myocardial performance index (MPI) for measuring regional and global left ventricular (LV) function using high-resolution echocardiography after myocardial infarction (MI) in mice. 48 mice underwent MI by a mid-LAD ligation. Echocardiography was performed under anesthesia at baseline and on...

Because we have a clinical impression that elderly patients have low back pain while in motion and standing, but less pain when sitting, we investigate characteristics of nonspecific low back pain (NSLBP), using a new detailed visual analog scale (VAS) scoring system. One hundred eighty-nine patients with NSLBP were divided into an elderly group (≥65 years old, n = 56) and a young group (<65 ye...

PURPOSE Assessment of left ventricular function is important in patients with heart disease. We hypothesized that regional wall motion assessed qualitatively by cine magnetic resonance imaging (MRI) can predict the left ventricular ejection fraction (EF). METHODS The correlations between MRI EF and the American Society of Echocardiography (ASE) score index and a modified ASE score index were ...

BACKGROUND Infarct size is a strong predictor of mortality and major adverse cardiovascular events after myocardial infarction. Acute reperfusion therapy limits infarct size and improves survival, but its use has been confined to patients with ST-segment-elevation myocardial infarction. The purpose of this study was to assess the relationship between echocardiographic parameters of left ventric...

AIMS Myocardial contrast perfusion echocardiography (MCE) allows simultaneous assessment of perfusion and function. However, low frame rate during MCE may reduce the viewer's ability to discern contractile dysfunction. This study sought to compare MCE and left ventricular opacification (LVO) settings with regard to wall motion abnormalities (WMA) at rest and during dobutamine stress echocardiog...

Abstract Background Ankle–brachial index (ABI) is a noninvasive and cheap measurement that used to define peripheral arterial disease (PAD). It as marker predict coronary artery (CAD). The SYNTAX score was created quantify the extent of CAD in patients with multivessel disease. Two-dimensional transthoracic echocardiography (TTE) useful method for evaluating left ventricular (LV) volumes ejecti...

BACKGROUND/AIMS The aim of this study was to identify changes in left ventricular (LV) performance in patients with a myocardial bridge (MB) in the left anterior descending coronary artery during resting and in an inotropic state. METHODS Myocardial strain measurement by speckle-tracking echocardiography and conventional LV wall-motion scoring was performed in 18 patients with MB (mean age, 4...

Flame stability inside a cylindrical micro-combustor was studied. Considering occurrence of heat recirculation, the respective relations were written and with parameters such as motion speed of reactants, flame propagation speed and thermal conductivity of the combustor’s wall, flame stability and its location inside micro-combustor were studied. It was found that for each thermal conductivity ...

background: the drug-eluting stent (des) decreases the rate of coronary restenosis and re-obstruction. the aim of this study was to assess prospectively the effectiveness of the new generation des on the left ventricular (lv) systolic and diastolic functions in patients with isolated severe proximal left anterior descending (lad) coronary artery stenosis. methods: a prospective study was conduc...
