Cardiac surgery (open-heart bypass, valve replacement) is among the more demanding recoveries: 6-12 weeks at home, sternal precautions for at least 6 weeks, cardiac rehab starting around week 4, mood swings + emotional volatility, and significant medication changes. As caregiver: support physical limits (no lifting, no pulling), watch for incision issues + signs of clots/infection, drive to all appointments, support cardiac rehab attendance, and stay calm through the emotional volatility. Below: the playbook.
Sternal precautions (6+ weeks)
For open-heart surgery (sternotomy approach), the breastbone is healing for 6-12 weeks. Restrictions:
Home setup before they come home
- Recliner — they shouldn’t sleep flat for 4-6 weeks. Same logic as shoulder/mastectomy.
- Heart-hugging pillow by the recliner. Hospital usually provides one.
- Walker or cane — surgeon will specify. Many patients use a walker for the first week.
- Removed throw rugs. Falls are dangerous post-cardiac.
- Phone + charger within reach.
- Easy bathroom path — close to recliner, well-lit.
Medications (be prepared for the list)
Your loved one is likely coming home with: blood thinners (warfarin, Eliquis, etc.), beta blockers, diuretics, statin, possibly insulin, anti-arrhythmics. The pill schedule is complex. Your job:
- Buy a 7-day pill organizer with AM/PM compartments
- Fill it weekly with them, not for them
- Set phone alarms for each dose
- Track INR if on warfarin — appointments matter
Watch for these (call doctor or 911)
- Fever above 100.4°F — possible infection
- Incision redness, drainage, opening — infection or dehiscence
- Calf swelling, pain, redness — possible clot
- Sudden shortness of breath — pulmonary embolism risk
- Chest pain different from incision pain — possible cardiac event
- Severe headache — bleeding risk on blood thinners
- Confusion, difficulty speaking, weakness on one side — stroke signs, call 911
The emotional volatility — surprisingly common
Many cardiac surgery patients experience post-surgical depression, anxiety, and tearfulness — sometimes severely. This is documented in cardiac literature; it’s NOT character weakness. Causes are mixed: anesthesia after-effects, medications, sleep deprivation, “near-death” emotional processing, hormonal shifts.
Your job:
- Don’t take outbursts personally
- Don’t try to argue them out of it
- Watch for severe depression — call cardiology or PCP
- Encourage cardiac rehab — exercise helps mood
Cardiac rehabilitation
Most patients are referred to cardiac rehab around week 4. This is supervised exercise + education + counseling, 12 weeks typical. Outcomes are dramatically better for patients who attend. Your job:
- Drive them to every appointment
- Pack a bag (water, towel, comfortable clothes, slip-on shoes)
- Encourage attendance even on bad-mood days
- Listen to what their cardiac rehab team says — they’re the experts on activity progression
Activity progression timeline
| Week | Activity |
|---|---|
| 1-2 | Walking around the house. 5-10 minute walks outside. |
| 3-4 | 20-minute walks. Light household tasks. No lifting. |
| 4-6 | Cardiac rehab starts. Gradual increase under supervision. |
| 6-8 | Sternal precautions begin to lift. Driving may be cleared. |
| 8-12 | Return to most normal activities. Exercise progressing. |
| 12+ | Most patients fully recovered. Some lifelong limitations. |
