Cardioprotective activity of A.V. Circulo in isoproterenol-induced myocardial necrosis

Area of Science:

• Pharmacology
• Cardiovascular Research
• Herbal Medicine

Background:

• Myocardial damage induced by isoproterenol is a common model for studying heart injury.
• Polyherbal preparations are increasingly investigated for therapeutic potential in cardiovascular diseases.

Purpose of the Study:

• To evaluate the cardioprotective activity of A.V. Circulo against isoproterenol-induced myocardial damage in a rat model.
• To assess the biochemical and histopathological effects of A.V. Circulo on cardiac tissue.

Main Methods:

• Rats were administered isoproterenol to induce myocardial damage.
• Chronic prophylactic treatment with A.V. Circulo was administered.
• Serum enzyme levels (creatinine phosphokinase, lactate dehydrogenase, serum glutamate oxaloacetic transaminase), DNA and protein content in heart tissue, serum lipid levels, and heart weight to body weight ratio were measured.
• Histopathological examination of cardiac tissue was performed.

Main Results:

• A.V. Circulo treatment prevented the increase in serum lysosomal enzyme activity.
• It significantly inhibited increases in heart tissue DNA and protein content and elevated serum lipid levels.
• The polyherbal preparation also inhibited the isoproterenol-induced increase in heart weight to body weight ratio.
• Histological analysis showed restoration of altered myocardial architecture.

Conclusions:

• A.V. Circulo exhibits significant cardioprotective activity against isoproterenol-induced myocardial damage in rats.
• The findings suggest that A.V. Circulo protects cardiac injury through biochemical and histopathological mechanisms.
• This polyherbal preparation shows promise for managing cardiac conditions.
