Evidence for a direct renal stimulating effect of prostaglandin E2 on renin release in patients with congestive heart failure.

abstract：BACKGROUND:Patients with primary amyloidosis (AL type) have a poor prognosis, in part due to frequent cardiac involvement. Although intracardiac thrombus has been reported in anecdotal cases, neither its frequency nor its role in causing mortality is known. Furthermore, the clinical and echocardiographic variables that...
