Obestatin pre-administration completely prevented acute lethality and shifted left ventricular remodeling toward an adaptive eccentric dilation pattern in a rat model of myocardial injury.
Does synthetic rat obestatin pre-administration improve outcomes in a rat model of isoproterenol-induced myocardial injury?
In a rat model of isoproterenol-induced myocardial injury, obestatin pre-administration prevented acute lethality and improved electrophysiological and structural remodeling parameters.

Cardiovascular diseases remain the leading cause of global mortality, and their most severe manifestations are associated with myocardial injury. Therefore, strategies aimed at limiting primary myocardial injury and regulating remodeling processes are a critically important approach in modern cardiology. In recent years, research focus has been on regulatory peptides possessing systemic protective and reparative potential. The aim of this study was to evaluate the possible cardioprotective properties of synthetic rat obestatin in in vivo studies using electro- and echocardiography in a model of myocardial injury induced by the β-adrenomimetic in rats. It was shown that obestatin pre-administration in a model of isoproterenol-induced myocardial injury completely prevents acute lethality, accelerates the recovery of physiological vegetative balance by normalizing heart rate variability parameters, and alters the pattern of left ventricular structural remodeling, shifting it toward a more adaptive eccentric dilation pattern. The cardioprotective effect of obestatin may be attributed to its normalizing effect on isoproterenol-induced prolongation of RR intervals and QRS complex, reflecting impaired intraventricular conduction.
