We have presented recommendations for the optimum acquisition of quantitative two-dimensional data in the current echocardiographic environment. It is likely that advances in imaging may enhance or supplement these approaches. For example, three-dimensional reconstruction methods may greatly augment the accuracy of volume determination if they become more(More)
OBJECTIVES We sought to test whether the ratio of peak tricuspid regurgitant velocity (TRV, ms) to the right ventricular outflow tract time-velocity integral (TVI(RVOT), cm) obtained by Doppler echocardiography (TRV/TVI(RVOT)) provides a clinically reliable method to determine pulmonary vascular resistance (PVR). BACKGROUND Pulmonary vascular resistance(More)
CONTEXT Depressive symptoms predict adverse cardiovascular outcomes in patients with coronary heart disease, but the mechanisms responsible for this association are unknown. OBJECTIVE To determine why depressive symptoms are associated with an increased risk of cardiovascular events. DESIGN AND PARTICIPANTS The Heart and Soul Study is a prospective(More)
To evaluate a simple noninvasive means of estimating right atrial (RA) pressure, the respiratory motion of the inferior vena cava (IVC) was analyzed by 2-dimensional echocardiography in 83 patients. Expiratory and inspiratory IVC diameters and percent collapse (caval index) were measured in subcostal views within 2 cm of the right atrium. Parameters were(More)
BACKGROUND The psychoactive stimulant 3, 4-methylenedioxymethamphetamine (MDMA), also known as "ecstasy," is widely used in nonmedical settings. Little is known about its cardiovascular effects. OBJECTIVE To evaluate the acute cardiovascular effects of MDMA by using transthoracic two-dimensional and Doppler echocardiography. DESIGN Four-session,(More)
The quantitation of two-dimensional echocardiographic images has been frustrated by the lack of concrete recommendations. The recent statement by the American Society of Echocardiography has rectified that deficiency. This discussion reviews the recommendations of the Society, focusing on the general and technical considerations for quantitation,(More)
OBJECTIVES The aim of this study was to test the hypothesis that atherosclerotic plaque in the thoracic aorta detected by transesophageal echocardiography is a marker for coronary artery disease. BACKGROUND Previous pathologic and roentgenographic studies have suggested a relation between aortic plaque and coronary artery disease but have lacked clinical(More)
