CABG Recovery Timeline: What to Expect After Bypass Surgery

Your Phased Roadmap to Recovery After Coronary Artery Bypass Grafting

Full recovery from CABG takes 3–6 months (up to a year for complete sternal healing). Individual variation is huge—age, comorbidities, surgical approach (on-pump vs. off-pump, number of grafts), and pre-op fitness all matter. Below is a phase-by-phase guide to help you know what’s normal and when to call your surgeon.

Phase 1: ICU / Immediate Post-Op (Days 0–2)

• Intubation → extubation (usually within 12 hours).
• Vasoactive drips, chest tubes, pacing wires, Foley catheter, arterial line.
• Pain control: PCA → scheduled multimodal (acetaminophen, gabapentin, limited opioids).
• Early mobilization: dangling at bedside → chair → few steps (led by PT/RT).

Phase 2: Step-Down / Telemetry (Days 3–5)

• Chest tubes removed; pacing wires pulled.
• Ambulate 3–4×/day; incentive spirometry every hour while awake.
• Transition to oral meds; start bowel regimen.
• Education on sternal precautions: no pushing/pulling >10 lbs, no driving, brace for coughing.

Phase 3: Discharge Home (Typically Day 5–7)

• Criteria: afebrile, independent ambulation, oral pain control, stable labs, understanding of red flags.
• Home health RN visit within 48 hours; outpatient cardiac rehab referral placed.

Phase 4: Weeks 2–6 (Early Outpatient)

• Sternal precautions strict until 8–12 weeks (bone knits at ~6 weeks, full strength 3–6 months).
• Cardiac Rehab (Phase II): 3×/week supervised exercise + education (insurance covers 36 sessions).
• Driving: Off opioids + surgeon clearance (usually 4–6 weeks).
• Incisional care: Keep clean/dry; watch for dehiscence, infection, clicking.

Phase 5: Weeks 6–12 (Building Endurance)

• Progress to unsupervised exercise (walking, cycling, light resistance).
• Return to desk work (6–8 weeks); physical labor (3–6 months).
• Lipid optimization (high-intensity statin), BP control, diabetes management, smoking cessation—non-negotiable.

Phase 6: 3–12 Months (Long-Term)

• Annual stress test / CT angiography per guideline.
• Graft patency: arterial (LIMA) >90% at 10 years; venous (SVG) 50–60% at 10 years.
• Lifestyle adherence determines longevity.

Red Flags – Call Your Surgeon Immediately

• Chest pain unrelieved by rest or nitroglycerin
• Fever >101°F, sternal redness, drainage, or clicking
• Sudden shortness of breath, palpitations, syncope
• Leg swelling (harvest site) with calf tenderness

Cardiac rehab is the single most evidence-based intervention for post-CABG survival and quality of life. Attend it.
