Background: Heart disease is the most common cause of death that has increased in developing countries. Coronary Artery Bypass Graft (CABG) surgery is one of the treatment methods in these patients that have been used widely over the past decade. This study was performed with aim of resolving the issues related to lack of patients' familiarity with anesthesia and surgery and inattention to their training needs due to anxiety and dysfunction of hemodynamic statue.

Methods: In this semi-experimental study, 124 patients who were candidates for CABG were randomly assigned to either the test or control groups. Patients' anxiety was evaluated by Amsterdam questioner and checklist was used for recording hemodynamic variables. The collected data were analyzed using the paired, independent t test and ANOVA in the SPSS.

Results: There were no significant differences between demographic variables in two groups. There were no significant differences between patients' anxiety, hemodynamic status, educational needs at admission time and before surgery in control group but in the intervention group, anxiety of patients decreased after the intervention (p<0.001). Hemodynamic variables in two groups changed before surgery (p<0.05). There was significant relationship between gender, level of education and patients' anxiety (p<0.05).

Conclusions: Considering the benefits of education on patient’s anxiety and hemodynamic status, more attention should be given by health care providers to patient education.
