Objectives. Determine the protective effect of oil Helianthus annuus (Sunflower) on myocardial infarction induced by epinephrine in New Zealand rabbits. Materials and methods. The rabbits were randomized into five groups (8 per group): blank, negative control, experimental 1 (10 mg / kg), experimental 2 (20 mg / kg) and three experimental (40 mg/ kg). Experimental groups 1, 2 and 3 received Helianthus annuus oil for two weeks. Epinephrine (2 mg/Kg) to the negative, Experimental Control 1, 2 and 3 groups was given over two consecutive days with an interval of 24 h after pretreatment with oil. Twenty four hours after the last administration, the rabbits were anesthetized and sacrificed. Serum troponin I and polymorphonuclear evaluated by .mu.m.sup.2. Results. Significant difference between the negative control group and the experimental groups 1, 2 and 3 was found in the serum variables troponin I and polymorphonuclear by .mu.m.sup.2. Conclusions. Helianthus annuus oil at doses of 20 mg/kg has protective effect on myocardial infarction induced by epinephrine in New Zealand rabbits
