Abstract

The plasma concentrations of oestrone (Oe1), oestradiol (Oe2) and oestrone sulphate (Oe1S) were measured in the femoral artery (FA), femoral vein (FV) and hepatic vein (HV) in seven men and three postmenopausal women undergoing catheterization for the evaluation of cardiac arrhythmias. None of the persons had congestive heart failure; conventional liver function tests were normal, and they were without any medication. The plasma concentration (mean +/- SD) for Oe1 was 34.6 +/- 19.5 pM in HV, 134 +/- 71.6 pM in FV and 93.4 +/- 48.5 pM in FA. The plasma concentration of Oe2 was 29.9 +/- 19.7 pM in HV, 80.3 +/- 42.7 pM in FV and 55.2 +/- 28.1 pM in FA. The results support the concept of peripheral formation of Oe1 and Oe2 and hepatic removal. The plasma concentration of Oe1S was 980 +/- 469 pM in HV, 945 +/- 463 pM in FV and 937 +/- 461 pM in FA. The small difference in plasma level of Oe1S between FA and FV was insignificant. In all persons the plasma level of Oe1S was higher in HV than in FA and FV (2P less than 0.01) indicating a net formation of Oe1S in the splanchnic area.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
