NID1 and myocardial infarction: Strikingly, NID1 + HA treatment resulted in a complete recovery in end‐diastolic volume (EDV), left ventricular end‐diastolic diameter (LVED), and left ventricular internal dimension at end ‐diastole (LVIDd) when compared with the pre‐MI/R baseline (Table S1, Supporting Information); however, the HA‐treated hearts also showed a recovery in these values, which should be taken into consideration as the HA carrier gel may have contributed to the positive effect in these parameters.
