Correlation between psychological co-morbidities and functional capacity in hospitalized coronary artery bypass graft surgery (CABG) patients.

Abstract

Background: Coronary Artery Bypass Graft surgery(CABG) is used to treat blockage or narrowing of one or more coronary arteries, hence it restore blood supply to the heart muscle. It can effectively relieve patient previous symptoms such as discomfort from chest pain (angina), fatigue ,breathlessness and  heart attack and increases life expectancy. It is usually a stressful events for patients. After cardiac surgery. If there is alterations in psychological comorbidities are common during recovery. Functional capacity is ability to perform daily tasks or exercise.This well documented value gives information to the doctors, medical staff, physiotherapist and caregivers to give early intervention for emotional disorders after surgery in hospitalized patients Aim: to find the Correlation Between Psychological Co-Morbidities And Functional Capacity. In Hospitalized Coronary Artery Bypass Graft Surgery Patients. Study design: cross-sectional, observational & correlation study. Method: A total of 40 hospitalized CABG patients from tertiary healthcare centre of a metropolitan city. The assessment tool used in this study was Depression, Anxiety and Stress Scale (DASS-21), 6 Minute walk test(6MWT), and Borg scale. The patients taken who fulfilled inclusion criteria and were willing to participate. After obtaining written consent, the DAS Scale was administered to patient and made to performing 6 minute walk test in cardio-vascular & thoracic surgery(CVTS) wards. For each participants required time was 30-40 mins. Results: Pearson correlation was used to find correlation between Psychological Comorbidities and Functional Capacity. r value for Psychological Comorbidities (DASS Scale score) and percent predicted value of 6MWT (Functional Capacity) is -.399 which shows weak negative correlation and is statistically significant with p value of 0.011. This implicates that if slightly high DASS Scale score for measuring psychological comorbidities was slightly reduced functional capacity. Conclusion: The result of this study showed weak negative correlation between Psychological comorbidities and Functional capacity. It may be due to post operative fatigue, incisional pain, unable to fall a sleep, loud noises in wards, coughing etc. So this study gives us an understanding to improve quality of life of patients.
