GH1 and myocardial infarction: These results were reiterated by our group, after GH administration via a biomaterial-scaffold locally in the LV myocardium of rats [40]; three weeks post-MI, GH-treated animals displayed improved LV end-diastolic and end-systolic diameters, as well as more elegant remodeling-indices such as ventricular sphericity and wall tension index; moreover, microvascular density and myofibroblast count in the peri-infarct area were elevated after treatment (Figure 4).
