Transfusion Medicine, EarlyView.Abstract Background Haemoglobin plays a crucial role in oxygen transport, and any acute deviation will trigger compensatory hemodynamic functions. While the consequences of anaemia are well documented, the effects of haemoglobin reduction in individuals without anaemia remain less explored. Patients with polycythaemia vera and healthy blood donors, who

Genetics of vasovagal syncope [PDF]
Autonomic Neuroscience, 2014 Vasovagal syncope (VVS) is the most frequent type of syncope and affects about 25% of the population. The role of genetic factors in VVS has long been debated. In this review we will discuss the current evidence that strongly suggests a major genetic component.Family aggregation studies have consistently shown that individuals with VVS more frequently ...
