ALB and ischemic stroke: Similarly, a subsequent prospective study, conducted by Chung et al, reported the same finding, suggesting that elevated albumin-corrected serum calcium levels were linked to a worse short-term prognosis and a heightened long-term risk of death following an acute ischemic stroke.[35] In line with studies conducted in Asia, a REGARDS study also discovered that elevated serum calcium levels were associated with a reduced risk of ischemic stroke.[36] Furthermore, this study identified a threshold effect of serum calcium levels on the risk of ischemic stroke.
