We compared patients with cerebrovascular ischemia and those with normal cerebrovascular imaging findings and found that the former group was older [61.6 ± 13.8 vs. 51 ± 15.8 years, P = 0.0001] and had lower serum (s)Cr [8.06 ± 2.65 vs. 9.09 ± 2.42 mg/dl, P = 0.0001] and higher serum CRP [9 (2–68) vs. 4.8(1–103) mg/l, P = 0.002] levels than the latter. Here, CRP is linked to brain ischemia.
