The heart needs a supply of oxygen-rich blood to work properly at a constant rate. This blood reaches the heart muscle through the coronary arteries. When these arteries get narrowed or blocked, the heart may not receive enough blood, particularly during physical activity.
Coronary artery disease is one of the common conditions treated in cardiology. Depending on the complication of the blockage, treatment may include medicines, lifestyle changes, catheter-based procedures or surgery. Coronary artery bypass surgery is one of the established surgical options for selected patients with significant coronary artery disease.
What Is Coronary Artery Disease?
Coronary artery disease develops when fatty deposits build up inside the walls of the coronary arteries. This process, known as atherosclerosis, can gradually reduce the space available for blood to flow.
Some people have no obvious symptoms in the early stages. Others may experience chest discomfort, shortness of breath or unusual tiredness, especially when walking quickly, climbing stairs or exercising.
If a plaque ruptures and a blood clot forms, the artery can become suddenly blocked. This may result in a heart attack and requires urgent medical attention.
When Is Bypass Surgery Considered?
Not every person with blocked coronary arteries requires bypass surgery. The decision depends on the location and extent of the blockages, the number of affected vessels, heart function and the patient’s overall health.
Doctors may consider coronary artery bypass surgery when there are several significant blockages, particularly when the disease affects important coronary vessels or when other treatment options are less suitable.
Patients searching for coronary artery bypass surgery in Dubai may undergo detailed cardiac investigations before a treatment plan is recommended.
How Is Coronary Artery Bypass Surgery Performed?
During the operation, a blood vessel taken from another area of the body is used to form an alternative pathway, allowing blood to flow to the heart muscle. This vessel is connected above and below the blocked section of the coronary artery.
The graft allows blood to flow around the narrowed or blocked area. Depending on the patient’s condition, one or several bypass grafts may be required.
The operation is performed under general anaesthesia. In conventional bypass surgery, a heart-lung machine may be used to maintain circulation while the surgeon works on the heart. In selected cases, surgery can be performed without using this machine.
Tests Before Bypass Surgery
A detailed assessment is carried out before surgery. The tests required can vary from one patient to another.
Common investigations may include:
- Electrocardiogram (ECG)
- Echocardiogram
- Coronary angiography
- CT scans when required
- Blood tests
- Chest imaging
- Assessment of kidney and lung function
These investigations help the cardiac team understand the extent of coronary artery disease and assess whether the patient is suitable for surgery.
Recovery After Bypass Surgery
Recovery after coronary artery bypass surgery takes time. Patients are usually monitored closely in hospital during the early stages. The time period of the hospital stay depends on the individual’s progress and whether any complications develop.
Once discharged, patients are gradually encouraged to increase their physical activity. Patients may need to avoid lifting heavy objects and intense physical activity until their surgical team confirms that it is safe to resume them.
Medicines are often prescribed after surgery to control cholesterol, blood pressure, blood clotting and other cardiovascular risk factors. Follow-up appointments allow doctors to monitor recovery and address any new symptoms.
Lifestyle Changes After Bypass Surgery
Surgery improves blood flow around existing blockages, but it does not remove the underlying risk factors for coronary artery disease. Long-term care therefore remains important.
Patients may be advised to:
- Stop smoking
- Follow a heart-healthy diet
- Maintain a healthy body weight
- Exercise according to medical advice
- Keep blood pressure under control
- Manage diabetes and cholesterol
- Take prescribed medicines regularly
- Attend scheduled cardiac reviews
Cardiac rehabilitation may also be recommended. It combines supervised exercise, education and support to help patients return safely to normal activities.
Other Treatment Options for Coronary Artery Disease
Treatment depends on the patient’s individual condition. Some people can manage their symptoms with medicines and changes to their daily habits. Others may benefit from angioplasty and stent placement.
During angioplasty, a catheter is passed through a blood vessel towards the narrowed coronary artery. A balloon may be used to widen the affected area, followed by placement of a stent to help keep the artery open.
For patients with complex or extensive coronary disease, bypass surgery may be discussed instead. The cardiac team considers the full clinical picture before recommending a treatment approach.
Choosing a Cardiology Centre
Cardiac treatment involves more than the procedure itself. Patients may wish to consider the availability of diagnostic testing, interventional cardiology, cardiac surgery, intensive care and follow-up services when selecting a centre.
Those looking for the best cardiology hospital in Dubai can also ask about the experience of the cardiology and cardiac surgery teams, the range of procedures available and how emergency and post-operative care are managed.
Clear communication is equally important. Patients should have an opportunity to discuss the proposed treatment, expected recovery, possible risks and alternatives with their healthcare team.
Conclusion
Coronary artery disease can range from mild narrowing to extensive blockage affecting several blood vessels. Treatment is selected according to the severity and pattern of disease, symptoms, heart function and overall health.
Coronary artery bypass surgery remains a prime treatment for selected patients with significant coronary artery disease. With appropriate medical care, lifestyle changes and regular follow-up, patients can continue working towards better long-term cardiovascular health
