Introduction: Among the cardiovascular diseases Coronary Artery disease is the leading cause of death worldwide. When the symptoms of these diseases cannot be controlled by pharmacological treatment, Coronary Artery Bypass Grafting (CABG) is the treatment option. Undergoing CABG surgery is the stressful event and that induce physiological and psychological impact to the patient during postoperative period. Nurses play a pivotal role in management of stressors related to CABG surgery and its management. Professional nurses are a major solution for securing optimal heath for persons undergoing cardiac surgery. Hence the researcher decided to focus the study to assess the effectiveness of selected nursing strategies on stress among the patients subjected to elective coronary artery bypass graft surgery Aims: The aim of the present study is to assess the effectiveness of selected nursing strategies on stress among the patients subjected to elective coronary artery bypass graft surgery. Methods: Quasi-Experimental, Pretest posttest control group design was used in this study. A Convenience sampling consisting of 200(100 Experimental and 100 Control group) selected from Frontier Lifeline Hospital at Chennai. During pretest and posttest the structured knowledge questionnaire to assess the knowledge level regarding CABG surgery and Modified Lazarus scale to assess the stress level were used as a tool for both the groups. Then Experimental group received selected nursing strategies for stress reduction whereas the control group received routine hospital care only. Results: In the pretest, the mean stress for the experimental group was found to be 78.83. After the intervention, the stress reduced to 39.42 and 30.20 respectively at the posttest-I and posttest-II. The mean stress for the control group was found to be 78.81, 36.01 and 56.02 respectively at pretest, posttest-I and posttest-II. The finding showed that in the experimental group the level of stress reduction was occurred more compared to the control group at p=0.001. Conclusion: Undergoing CABG surgery patient’s perception of the stressors had to be paid attention for a smooth recovery.
