Diagnosis
Before your procedure, your doctor will confirm your diagnosis and assess your heart function with several tests.
Tests that may be done
- Electrocardiogram (ECG) – records your heart's electrical activity
- Echocardiogram – ultrasound pictures of your heart
- Blood tests – to check your overall health
- Chest X-ray – to see the size and shape of your heart
- Coronary angiogram – special X-rays of your heart arteries (if needed)
What to expect at your appointment
You will meet with your cardiologist and possibly an anaesthetist. They will explain the procedure, risks, and what to do to prepare. You will sign a consent form. You may be asked to stop taking some medicines, fast for a period, and arrange for someone to take you home after the procedure.
Treatment
Preparation for a heart procedure involves a series of steps to ensure your body is ready and to reduce the risk of complications.
Self-care at home
- Quit smoking as soon as possible
- Eat a heart-healthy diet
- Stay physically active as advised
- Manage stress with relaxation techniques
- Get a good night's sleep before the procedure
Medical treatments
Your doctor may prescribe medications to control blood pressure, cholesterol, or heart rhythm. You may need to stop blood-thinning medications several days before the procedure. Always follow your doctor's instructions exactly. Never change or stop any medicine without talking to your care team.
When is surgery considered?
If you are having open-heart surgery, such as bypass or valve replacement, the preparation may include additional tests and hospital admission the day before.
Living with this condition
After the procedure, recovery times vary. You will need to rest and gradually increase activity. Follow discharge instructions carefully, including how to care for incision sites and when to resume daily activities.
Lifestyle tips
- Take all medications exactly as prescribed
- Attend all follow-up appointments
- Watch for signs of infection at incision sites (redness, warmth, drainage)
- Avoid heavy lifting for a few weeks
Diet and exercise
Your doctor or dietitian will advise on a heart-healthy diet low in salt and saturated fat. Light walking is often encouraged soon after surgery, but avoid strenuous exercise until cleared by your care team.
Mental health and emotional wellbeing
It is common to feel anxious, depressed, or overwhelmed after a heart procedure. Talk to your care team if you are struggling, as they can connect you with counselling or support groups.
Prevention
You cannot always prevent the heart conditions that lead to a procedure, but you can reduce your risk by adopting a healthy lifestyle and managing chronic conditions like high blood pressure, diabetes, and high cholesterol.
Vaccines
Ask your doctor about getting a flu shot and pneumonia vaccine before your procedure to reduce the risk of infections.
Screening programmes
Regular check-ups with your doctor can help detect heart problems early and may reduce the need for emergency procedures.
Complications
If left untreated
- Increased risk of bleeding or infection
- Anaesthesia complications
- Longer recovery time
- Need for unplanned additional procedures
Long-term outlook
With proper preparation and follow-up care, most people recover well from heart procedures and experience significant improvement in their quality of life. Your healthcare team is committed to helping you every step of the way.
