How long after Coronary Artery Bypass Grafting (CABG) can a patient return to normal activities?

Return to Normal Activities After CABG

Most patients can begin light daily activities immediately after discharge, with progressive return to normal activities over 6-8 weeks as the sternum heals, though specific activities like driving may resume within 1 week and sexual activity within days if exercise tolerance is adequate. 1, 2

Immediate Post-Discharge Period (First Week)

• Daily walking is encouraged immediately upon discharge and should begin the day after uncomplicated CABG 1
• Driving can begin within 1 week after uncomplicated surgery if permitted by local motor vehicle laws 1
• Patients can walk on flat surfaces and climb stairs within a few days after uncomplicated procedures 1
• Continuous cardiac monitoring should have been performed for at least 48 hours post-operatively to detect arrhythmias 1

Sexual Activity Resumption

• Sexual activity can usually be resumed within days after discharge, provided exercise tolerance is adequate 1
• The practical assessment is the ability to climb one flight of stairs without difficulty, which indicates sufficient cardiovascular capacity 1
• Proactive physician counseling about safe resumption of sexual activity as patients reengage in daily activities is beneficial 1
• Post-CABG patients are more likely to resume sexual activity than MI survivors 1

Progressive Activity Timeline (Weeks 2-8)

• The sternum requires 6-8 weeks to heal adequately, which is the primary determinant for when patients can safely progress to more strenuous activities 1, 2
• Physical activity counseling and cardiac rehabilitation should begin early, with formal programs starting 4-8 weeks after CABG 1
• Gradual increase in activity is recommended throughout the 6-8 week sternotomy healing period 2
• Patients should avoid high-impact activities, heavy lifting, and strenuous physical exertion until the sternum is fully healed at 6-8 weeks 2

Return to Work Considerations

• Return to work timing is complex and depends on job physical demands, with rates ranging from 63-94% 1
• In clinical trials, patients were encouraged to return to work 2 weeks after primary PCI for STEMI without adverse events, though CABG typically requires longer recovery 1
• 45% of working patients returned to work within 2 months, 69% within 3 months, and 87% within 6 months after CABG 3
• Factors predicting early return to work include younger age, higher education, shorter preoperative work absence, positive attitude toward returning to work, normal troponin T levels, and shorter cardiopulmonary bypass time 3

Cardiac Rehabilitation (Class I Recommendation)

• Cardiac rehabilitation is recommended for all eligible patients after CABG 1
• Formal programs beginning 4-8 weeks post-CABG with 3-times-weekly sessions for 3 months result in 35% increase in exercise tolerance 1
• Participation reduces all-cause and cardiac mortality and improves multiple cardiovascular risk factors 1
• Physician referral is the most powerful predictor of patient participation 1

Common Pitfalls and Patient Concerns

• The first month after discharge is particularly challenging, with patients experiencing substantial uncertainty about what is normal for postoperative pain, physical activity limits, and medication management 4
• Patients at 2 weeks post-CABG report uncertainty about surgical site assessment, sleep difficulties, irritability, and insufficient discharge information 4
• By 4 weeks, symptom levels decrease and life begins returning to normal, though concerns about driving, sexual function, and hospital follow-up may persist 4
• Patients over 70 years or with severely impaired left ventricular function require more conservative activity progression and closer monitoring 2

Functional Assessment

• Graded exercise treadmill testing can determine safety of activities by measuring metabolic equivalent of task (MET) levels and comparing to energy requirements of different activities 1
• Exercise testing should assess safety parameters including clinical, hemodynamic, and rhythmic stability, ischemic threshold (if incomplete revascularization), and degree of left ventricular impairment 1
• Stress imaging is preferred over exercise ECG alone for detecting restenosis if clinically indicated 1
