Alpha-terpineol (TPN) is one of the major components of the resin obtained from Protium heptaphyllum. This plant has been utilized as medicine by Brazilian indigenous tribes to treat cardiovascular diseases. Scientific reports have shown that the TPN possesses vasorelaxant and antihypertensive effects. This study was conducted to assess the cardioprotective action of TPN against isoproterenol (ISO)-induced cardiotoxicity. Wistar rats were randomly divided into six groups. Rats were orally administered with TPN (25, 50, and 75 mg/kg, respectively) for 15 days, and ISO was administered (85 mg/kg, subcutaneously) on the 14th and 15th days. At the end of the experiment, the hemodynamic, baroreflex test, ECG, biochemical, histological, and morphometric changes were monitored from control and experimental groups, i.e., on the 15th day. ISO-induced myocardial infarcted rats showed an increase in mortality rates, cardiac marker enzymes, tachycardia, hypertrophy, myocardium necrosis, edema, hemorrhagic areas, infiltration of inflammatory cells like lymphocytes, and increased myocardial infarct size. However, pretreatment with TPN significantly inhibited these effects of ISO. The histopathological findings obtained for the myocardium further confirmed the biochemical results. Thus, the present study provides evidence for the efficacy of TPN against ISO-induced myocardial infarction in rats. Display omitted
