After recovering from coronary artery bypass surgery, most people feel better. Some people remain symptom-free for many years. The results and long-term outcomes depend on how well blood pressure and cholesterol levels are controlled, and how well chronic conditions such as diabetes are managed. It's important to take medications as directed and follow provider recommendations for diet and exercise.

Recovery time

It usually takes about 6 to 12 weeks to recover after coronary artery bypass surgery, though each individual is different. The cardiologist and primary health care provider are the best people to estimate how long recovery will take and what can be expected... Though foremost they will reiterate that recovery time greatly depends on how well your loved one follows recommendations. They can also tell you and your loved one when to start resuming regular activities like work, driving, and traveling. 

Cardiac rehabilitation

After leaving the hospital, most people will complete a cardiac rehabilitation program. These are typically 12-18 weeks, 2 to 3 sessions per week (36 sessions). Often called cardiac rehab, this supervised program of education, counseling, and exercise helps improve heart health after heart surgery. Expect your loved one to start moving and walking while still in the hospital, though cardiac rehab helps with continued recovery and rebuilding strength after intensive cardiac procedures or events like heart attacks. Cardiac rehab programs are conducted at outpatient facilities by specially trained and highly qualified staff. (Moving portions of cardiac rehabilitation to remote online services is currently being explored.)


The breastbone is rejoined with wires that remain in the bone and are not visible under the skin. There remains a risk, however, that a wire will break and cause discomfort and even protrude through the skin. Should your loved one experience any indications that a wire may have snapped, contact the cardiologist's office.

The overlying skin is stapled. Once the skin is closed over the incision, the staples are removed. The 8-10 inch scar down the middle of the chest will continue to heal and scab and will become fainter over time, though it will never disappear. About 10% of people experience what's called keloid scarring, whereby there is an overgrowth of scar tissue and the scar becomes thick and raised. (People under 30, as well as people of African, Asian, or Latin descent, and those with a family history of keloids, are more susceptible to this type of scarring.)
