Myocardial infarction, Polyherbal formulation, Isoprenaline hydrochloride, Oxidative stress, Free radicals


Objective: Myocardial infarction (MI) continues to be a major public health problem in the world. The prepared polyherbal formulation (PHF) exhibit cardioprotective effects by several mechanisms. The objective of the research was to evaluate the antioxidant effect of a polyherbal formulation in isoprenaline hydrochloride (ISO) induced myocardial infarction in rats.

Methods: Oxidative stress and myocardial infarction was induced by administration of isoprenaline hydrochloride (25 mg/kg) for 2 d. The degree of protection was determined by measuring the levels of lipid peroxidation (LPO), enzymatic antioxidants (superoxide dismutase-SOD, Catalase, Glutathione peroxidase) and non-enzymatic antioxidants (Vitamin C, E and reduced glutathione-GSH).

Results: Two different doses (250 mg and 500 mg/kg body wt) of the formulation was used to prove the cardioprotective effect. Pretreatment with polyherbal formulation significantly (P<0.05) lowered LPO and elevated the enzymatic and non-enzymatic antioxidants in heart homogenate.

Conclusion: The polyherbal formulation exhibited cardioprotective activity, which could be attributed to its antioxidant activity.
