A coronary artery bypass graft (CABG) isn't a cure for heart disease, so it's important to adopt a healthy lifestyle and continue taking any prescribed medication after the operation to reduce your risk of getting heart problems in the future.
There are a number of lifestyle changes you can make after having a coronary artery bypass graft to help reduce your risk of further heart problems. These are described below.
An unhealthy diet can increase your chances of developing heart problems after a coronary artery bypass graft. To reduce this risk, you should ensure your diet is low in saturated fat and salt, but high in fibre and omega-3 (a fatty acid that can help reduce your cholesterol levels).
Examples of foods you should try to avoid include:
Instead, you should try to eat:
Also, cut down on the amount of salt you add to your food and check the nutrition labels on food when shopping to find products with the lowest levels of salt.
Once you've fully recovered from the effects of surgery, you should exercise regularly to reduce your risk of developing further heart problems.
Adults should do at least 150 minutes (2 hours and 30 minutes) of moderate-intensity aerobic activity every week. Moderate-intensity means an activity that's strenuous enough to leave you slightly breathless.
Examples of moderate-intensity aerobic activities include:
If you find it difficult to achieve 150 minutes of activity a week, start at a level you feel comfortable with (for example, around 10 minutes of light exercise a day) and gradually increase the duration and intensity of your activity as your fitness starts to improve.

If you're overweight or obese, you can reduce your risk of further heart problems by trying to reach a healthy weight. To find out whether you need to lose weight you can use the BMI healthy weight calculator.
The best way to lose weight is to make sure you have a healthy diet and exercise regularly. You may find it helpful to follow a structured weight loss programme, such as the free NHS weight loss plan.
Smoking can significantly increase your risk of developing heart problems because it narrows your arteries and raises your blood pressure.
You can also call the NHS Smoking Helpline on 0300 123 1044. Specially trained helpline staff will offer you free expert advice and encouragement.
If you're committed to giving up smoking but don't want to be referred to a stop smoking service, your GP should be able to prescribe medication to help with withdrawal symptoms you may experience after giving up.

If you drink alcohol, don't exceed the recommended limits.
One unit of alcohol is roughly half a pint of normal-strength lager or a single measure (25ml) of spirits. A small glass of wine (125ml) contains about one-and-a-half units of alcohol.
Regularly exceeding the recommended alcohol limits can raise your blood pressure and cholesterol level, increasing your risk of heart problems.
You'll probably need to take less medication after having a coronary artery bypass graft, but you may still need to take some to reduce your risk of further problems.
Some of the medications you may be prescribed are described below.
Anticoagulants and antiplatelets are types of medication that reduce the risk of blood clots forming.
Examples of these medications include:
After a coronary artery bypass graft, you may be prescribed one of these medications to take for a few months, or for the foreseeable future.
If you're prescribed one of these medications after your operation, it's important to take it because they can reduce your risk of serious problems such as heart attacks.
Statins are a type of medication used to lower your blood cholesterol level. This will help prevent further damage to your coronary arteries and should reduce your risk of problems such as heart attacks.
Examples of statins include:
In most cases, treatment with statins will be recommended for life.
Depending on the specific reason why you had a coronary artery bypass graft, you may also be prescribed some other medications, such as beta-blockers and angiotensin-converting enzyme (ACE) inhibitors.
