The cardiac tissue histopathological photos after induction of myocardial infarction (100×). Control rat animals received saline 10 ml/kg with standard fed and water ad libitum throughout the experimental period. ISO control rats were orally fed normal saline once daily for 28 days and in addition received isoproterenol (85 mg/kg body weight) on the 29th and 30th day at an interval of 24 h. Date extract rats (D1–D4) were pretreated with dates extract (D1–D4) (200 and 400 mg/kg body weight, respectively) for a period of 28 days and in addition received isoproterenol 85 mg/kg body weight) on the 29th and 30th day at an interval of 24 h. These slides were then observed under light microscope for histopathological changes.
