Increased IGF1 levels in relation to heart
... Cardiovascular disease is a major cause of morbidity and mortality in the western world. A number of studies have shown that IGF-1 is related to CV disease, but the mechanisms involved are still not clear (1-3). Both low and high levels of circulating IGF-1 have been reported to be associated with i ...
