Patients with higher hs-CRP concentrations are more likely to develop stroke, myocardial infarction, and severe peripheral vascular disease. hs-CRP results are used to assign risk as follows: < 1.0 mg/L lowest tertile, lowest risk. 1.0-3.0 mg/L middle tertile, average risk. > 3.0 mg/L highest tertile, highest risk. CRP is a nonspecific marker of inflammation and a variety of conditions other than atherosclerosis may cause elevated levels. |
