Compensatory mechanisms following myocardial infarction, including: measured heart rate ($HR$), computed systemic vascular resistance ($SVR$), fitted end-systolic elastance of non-infarcted region $\left(E_n\right)$, and fitted stressed blood volume ($SBV$). Each rat’s response is shown in a different color (n = 13). The change in computed mean arterial pressure ($MAP$) is also shown. No change is indicated by the gray dashed line and a significant mean change for all animals is indicated by a dark solid line (p < 0.05). Paired parametric t-tests were performed on all metrics except $MAP$, which failed the normality test and was analyzed with a Wilcoxon matched-pairs signed rank test.
