Pathophysiologic significance of free and conjugated dopamines in congestive heart failure.

abstract：BACKGROUND:Symptoms of anxiety are associated with increased risk of coronary artery disease and potentially poor prognosis among patients with existing coronary artery disease, but whether symptoms of anxiety influence atherosclerotic progression among such patients is uncertain. Accordingly, we evaluated the hypothes...
