For instance, in a study of 79 patients with non ST-segment elevation ACS, copeptin on admission was higher in non-ST-segment elevation MI (NSTEMI) than in unstable angina, and was also positively, albeit weakly to moderately at best, correlated with each of the GRACE (r = 0.43), TIMI (r = 0.55), and SYNTAX (r = 0.65) scores (p < 0.001 for all) [69]. Here, AVP is linked to angina pectoris.
