Zinc complex of acetylsalicylic acid (Zn(ASA)2) improves cardiac pump function in isoproterenol (Iso)-induced myocardial ischemia in rats. (a) Stroke volume, (b) the slope Emax of the left-ventricular end-systolic pressure–volume relationship, and (c) systemic vascular resistance. *P < 0.05 vs. control, #P < 0.05 vs. Iso. ASA indicates acetylsalicylic acid. n = 7 in the control, ASA + Iso and Zn(ASA)2 groups, n = 11 in the Iso group, n = 12 in the Zn(ASA)2 + Iso group
