Introduction: Coronary artery disease secondary to atherosclerosis is the most common cause of mortality. Coronary angiography is the most precise method for determining the extent of disease in the coronary vascular bed. Arterial stiffness has been proposed as a marker of atherosclerosis in some studies. One of the noninvasive methods for the determination of arterial stiffness is Doppler echo...

BACKGROUND Because of safety, repeatability, and portability, clinical echocardiography is well established as a standard for cardiac anatomy, cardiac function, and hemodynamics. Similarly, application of echocardiography in commonly used rat experimental models would be worthwhile. The use of noninvasive ultrasound imaging in the rat is a potential replacement for more invasive terminal techni...

Various methods of Doppler echocardiography are useful in the analysis of flow dynamics within the heart and the pulmonary circulation in patients with COPD. In addition, to distinguish patients with increased pulmonary artery pressures from those with normal pressures, Doppler techniques provide quantitative methods for estimating pulmonary artery pressures non-invasively. Doppler echocardiogr...

A 27-year-old man who was known to have hypereosinophilic syndrome (HES) underwent evaluation at our echocardiography laboratory for exertional dyspnea. Laboratory tests revealed leukocytosis (5.4  10/L) with marked eosinophilia (34.6%; normal range, 4%), in addition to an elevated level of tryptase (70 ng/mL; normal range, 13.5 ng/mL). Two-dimensional transthoracic echocardiography showed a...
