1. Evidence from numerous experiments incorporating central blood volume expansion and changes in sodium status supports atrial stretch as the prime determinant of ANF release. 2. Plasma ANF levels are the result of both secretion and clearance of the peptide. Clearance is altered by a number of factors, including changes in posture in normal man and is probably impaired in disease states with diminished renal and hepatic blood flow. 3. In normal subjects an inverse relationship exists between plasma ANF values and renin-angiotensin-aldosterone system activity. This relationship is lost and replaced by a positive association in heart failure, presumably reflecting the abnormal concurrence of increased atrial stretch and diminished renal perfusion in this condition. Plasma ANF values rise with increasing severity of heart failure and fall with effective treatment. 4. Plasma ANF values are elevated in hypertension and cardiac tachyarrhythmias possibly reflecting raised central venous and atrial pressures. 5. A variety of other disorders may be associated with abnormal plasma ANF values including cirrhosis and the syndrome of inappropriate ADH secretion. 6. Evidence from low-dose infusions of ANF in normal volunteers suggests that the variations in plasma ANF seen in health and disease are sufficient to exert biological effects. 7. The advent of a specific antagonist is needed to provide further insight into the physiological and pathophysiological roles of ANF.
