Abstract

Smoking significantly raises the chance of developing cardiovascular disease (CVD), which is one of the leading causes of mortality globally. Goal: To ascertain how smoking affects patients' functional ability and quality of life following coronary artery bypass grafting surgery. Methods: A cross-sectional design in which patients of both gender aged between 40 and 70 years were selected those who underwent phase 2 rehabilitation phase. Based on their smoking history, patients were chosen from Sardar Fateh Khan Buzdar Institute of Cardiology in Dera Ghazi Khan and split into three groups: smokers and non-smokers. Structured interviews, the SF-36 questionnaire to assess quality of life after five days, and the Six-Minute Walk Test (6MWT) to gauge functional capacity were used to gather data. Patients’ demographic information, medical history, and post-operative recovery details were also recorded. Data were analyzed using SPSS version 26.0. Results: Of 189 participants, non-smokers (33.9%) showed significantly better 6MWT performance than smokers (p < 0.05). Non-smokers had significantly better physical function scores and faster Sit to Stand test times than smokers (p < 0.05). Additionally, non-smokers reported a higher Physical Component Score (52.37 ± 6.12) compared to smokers (48.29 ± 7.45, p < 0.01). A strong negative correlation was found between the number of smoking packs per year and overall health outcomes, with 24.9% of smokers reporting more than 20 packs per year. Conclusion: Smoking negatively impacts rehabilitation by reducing functional capacity and lowering quality of life.
