Background: Coronary Artery Bypass Grafting (CABG) is a standard surgical intervention to restore normal blood flow to an obstructed coronary artery. Alterations in sleep patterns are common during recovery after cardiac surgery. Functional Capacity is an important dimension of human functioning, and also a well-documented concern for cardiac surgery patients throughout recovery.

Objective: To find the correlation between Sleep Quality and Functional Capacity in Hospitalized Coronary Artery Bypass Grafting Patients.

Study Design: cross- sectional, observational, correlation study

Method:  40 hospitalized CABG patients who fulfilled the inclusion criteria and were willing to participate. After obtaining the written consent, the participants were administered Pittsburgh Sleep Quality Index (PSQI) and made to performing 6 Minute Walk Test (6MWT) in the Cardio-Vascular & Thoracic Surgery (CVTS) wards. The time required was 30-40 minutes per participant.

Results: Spearman Ranks Correlation was used to find correlation between Sleep Quality and Functional Capacity. It was observed that there is a strong negative correlation between Global Score of Pittsburgh Sleep Quality Index (Sleep Quality) and Percent predicted value of 6MWT (Functional Capacity) with a r value of -0.7301 statistically significant with a p value of 0.0001. Higher the Score on Pittsburgh Sleep Quality Index (PSQI) lower was the Functional Capacity.

Conclusion: The results of this study showed strong correlation between Sleep Quality and Functional Capacity. Sleep quality should be considered as one of the important components of cardiac rehabilitation to improve the functional capacity of these patients.

Key words: CABG, Sleep Quality, Functional Capacity.
