One recent meta-analysis [27] evaluated the prognostic value of copeptin in patients with acute coronary syndrome and concluded that elevated copeptin was associated with higher mortality with a pooled sensitivity of 0.77% (95% CI: 0.59–0.89) and a pooled specificity of 0.60 (95% CI: 0.47–0.71). Here, AVP is linked to acute coronary syndrome.
