Does intensity of rate control influence outcome in persistent atrial fibrillation?
In patients treated with a rate control strategy, no differences were observed in terms of cardiovascular morbidity, mortality, and quality of life between the observed differences in level of rate control throughout follow-up.
The results of the current study revealed in vivo the association between elevated hCG and amniotic fluid erythropoietin levels which, in turn, supports the concept of early placental damage. The underlying pathology seems to be sufficient to cause an erythroblastic response.
