| pubmed-article:1493665 | pubmed:abstractText | Sodium balance plays a primary role in blood pressure regulation. Atrial natriuretic peptide, a recently discovered natriuretic substance, seems to participate in renal sodium handling, but its behavior in essential hypertension has not been fully defined. In our study, to avoid the "contamination" of factors other than hypertension, we evaluated the plasma levels of atrial natriuretic peptide in young men at military draft age. Our main results showed that plasma atrial natriuretic peptide levels are higher in young hypertensives with low plasma renin activity and low urinary excretion of active kallikrein. The influence of a positive genetic background for essential hypertension on plasma atrial natriuretic peptide levels was also investigated. Our data showed slightly elevated levels of the atrial hormone in young normotensives with a family history of hypertension. | lld:pubmed |
