Introduction: Coronary artery diseases are the primary and most common cause of death in all ages. ‎Coronary artery bypass grafting (CABG) surgery as a common treatment intervention is considered ‎necessary in patients with coronary artery disease. Complications may occur during and after ‎‎(CABG) surgery. Among major complications are hemodynamic changes after surgery which is still ‎an important matter. ‎

 Objective: The aim of this study is to determine level of hemodynamic‏ ‏changes after coronary ar-‎tery bypass grafting and its related factors in patients undergoing CABG admitted to post cardiac ‎intensive care unit and the effect of related factors on severity and weakness of complications. ‎ Methods: In this descriptive cross – sectional study, ‎‏288‏‎ (CABG) patients who had coronary artery ‎bypass grafting (CABG) and admitted to the post cardiac intensive care unit in Dr. Heshmat educa-‎tional-therapeutic hospital in Rasht were selected by sequential sampling method and studied using ‎questionnaire. Statistical analysis performed with appropriate tests chi square test, fisher exact test ‎and logistic regression and correlations between dependent and independent variables were identi-‎fied.‎

 Results: According to the research findings, ‎‏36%‏‎ of patients after surgery had systolic blood pres-‎sure changes out of normal range, ‎‏49%‏‎ had diastolic blood pressure changes, ‎‏65%‏‎ heart beat ‎changes, and ‎‏34%‏‎ had central venous pressure changes out of normal limits. A significant relation-‎ship was observed between interfering factors such as Body Mass Index, ejection fraction, history ‎of Myocardial- infraction, number of grafts, duration of the connection to ventilator, duration of ‎cardiopulmonary machine use, duration of aorta clamp, hypothermia, and level of hemoglobin and ‎hematocrit with hemodynamic variables. ‎ Conclusion: The research findings may be considered in planning for prevention, diagnosis and ‎early treatment of any possible complications, consequently the quality of care for CABG patient ‎will improve.‎
