Recovery after heart bypass surgery: what to expect
Recovery after heart bypass surgery depends on whether it was done by keyhole (MICS) or open surgery. Most keyhole bypass patients leave hospital within 3 to 5 days and return to daily activities in about two weeks, while open-chest bypass generally takes longer because the breastbone needs time to heal. Your surgeon and cardiologist guide your individual recovery.
How long is the hospital stay after bypass surgery?
After surgery you are cared for in the cardiac intensive care unit before moving to a ward. Most keyhole (MICS) bypass patients are discharged within 3 to 5 days, compared with 7 to 10 days typical after traditional open-chest bypass. Your exact stay depends on your procedure and how your recovery progresses. You can read more on the heart bypass surgery page.
When can I return to normal activities?
Because the breastbone is not divided in the keyhole approach, many patients return to normal daily activity in about two weeks. After traditional open bypass, the breastbone needs several weeks to heal, so activity is built up more gradually. Returning to driving, work and heavier activity is guided by your surgeon and cardiologist and depends on your job and recovery, so ask your team for advice specific to you.
What is cardiac rehabilitation?
Cardiac rehabilitation is a supervised programme of gradual exercise, education and support that helps you recover safely and build confidence after heart surgery. It also covers medication, healthy eating and managing risk factors. Your care team will advise when and how to start.
How can I look after my heart after bypass surgery?
Bypass surgery treats the blockages but does not cure the underlying coronary artery disease, so long-term heart health matters. This usually includes taking your prescribed medication, attending follow-up with your cardiologist, not smoking, eating well, staying active as advised, and controlling blood pressure, cholesterol and diabetes. Your cardiologist leads this ongoing care.
When should I seek advice during recovery?
Follow the specific advice your surgical team gives you on discharge. In general, contact your care team if you notice increasing pain, redness or discharge from the wound, fever, worsening breathlessness, or an irregular or racing heartbeat. If you have severe chest pain or collapse, seek emergency care immediately. This article is general information and does not replace the personalised advice of your own doctors.
