Effect of GHRP-6 on the left ventricular ejection fraction in an experimental model of dilated cardiomyopathy (DCM). Echocardiography data were derived from our DCM model including the prevention and the regression study protocols in rats.³⁵ The prevention protocol conceived the concurrent administration of GHRP-6 as part of a prolonged treatment with doxorubicin. The concomitant GHRP-6 completely prevented cardiac function failure evaluated as the percentage of ejection fraction by echocardiography. The regression approach examined the GHRP-6 intervention once LVEF was already deteriorated. As shown, the therapeutic administration schedule introduced a full functional recovery of cardiac muscle. Data corresponding to percentage of ejection fraction (%EF) are represented as a mean value ± standard error of the mean for each experimental group. (*), (**), and (***) represent the statistically significant differences between groups treated either with placebo or GHRP-6, according to Student’s t-test.
