Coronary artery disease, also known as ischaemic heart disease, is one of the leading causes of mortality in Spain and worldwide. But what exactly is this condition, and how does it affect our heart?
In this article, we will explore what coronary artery disease is, its causes, symptoms, and available treatments.
What are the coronary arteries?
The coronary arteries are essential blood vessels that supply oxygen-rich blood and nutrients to the heart, allowing it to function correctly. They encircle the heart like a crown, hence their name.
The main coronary arteries are:
- The left coronary artery branches into the left anterior descending artery and the circumflex artery, supplying blood to most of the heart.
- The right coronary artery supplies blood to the parts of the heart that control the heart rhythm and the inferior surface of the left ventricle.
These arteries divide into smaller vessels that spread throughout the heart muscle, ensuring that every part receives the oxygen and nutrients it needs to function.
What is coronary artery disease?
Coronary artery disease is a set of heart conditions that occur when the blood supply to the heart is insufficient due to the buildup of atheromatous plaque in the walls of these arteries. This plaque primarily comprises cholesterol, fat, and other substances in the blood. The buildup of plaque inside the arteries is known as atherosclerosis, and as it progresses, it reduces blood flow to the heart, which can lead to various heart problems.
Clinical manifestations of coronary artery disease
Coronary artery disease occurs when the heart does not receive the blood and oxygen it needs, which can lead to various serious complications, including:
- Angina: Chest pain or discomfort due to insufficient blood supply to the heart. It may feel like pressure, tightness, or a heavy sensation in the chest.
- Myocardial ischaemia: Reduced blood flow to the heart, which in many cases may not cause immediate symptoms but can increase the risk of a heart attack.
- Myocardial infarction: Commonly known as a heart attack, it occurs when blood flow to a part of the heart is completely blocked, causing the death of the affected heart tissue.
Over time, coronary artery disease can also weaken the heart muscle, reducing its ability to pump blood efficiently to the rest of the body. This can also contribute to the development of arrhythmias, which are changes in the heart’s normal rhythm, ranging from irregular heartbeats to dangerously fast or slow rhythms.
Causes and risk factors of coronary artery disease
Coronary artery disease is a common condition that can seriously affect heart health. Although multiple factors influence its development, it is possible to reduce the risk by adopting healthy habits and controlling certain medical conditions. Among the most critical risk factors are:
- Age: As we age, the risk of arteries becoming damaged or narrowed increases.
- Gender: Men generally have a higher risk of developing this disease. However, in women, the risk increases significantly after menopause.
- Family history: If there is a family history of heart disease, the risk of developing coronary artery disease is higher.
- High blood pressure: Uncontrolled hypertension can harden the arteries, making them stiffer and increasing the risk of heart problems.
- High cholesterol: Elevated levels of “bad” cholesterol (LDL) in the blood can contribute to the development of atherosclerosis.
- Diabetes: Type 2 diabetes and coronary artery disease share some risk factors, such as obesity and hypertension. People with diabetes have a higher risk of developing heart problems.
- Psoriasis and rheumatoid arthritis: Some chronic inflammatory diseases have been linked to the development of coronary atherosclerosis.
- Smoking: Smoking increases the risk of coronary artery disease and acute myocardial infarction.
- Chronic kidney disease increases the risk of coronary artery disease due to the changes it causes in circulation and blood pressure.
- Unhealthy lifestyle: Lack of exercise, smoking, chronic stress, an unhealthy diet, excessive alcohol consumption, or insufficient sleep can damage the arteries and increase the risk of developing coronary artery disease.
Symptoms of coronary artery disease
Coronary artery disease can develop slowly from childhood. In some people, symptoms become apparent between the ages of 30 and 40, while others may not experience symptoms until after age 50 or 60. As the coronary arteries narrow, symptoms become more frequent and severe. It is essential to be aware of the signs and symptoms that may indicate heart problems. These can include:
- Chest pain or pressure (angina)
- Shortness of breath
- Unusual fatigue
- Dizziness or lightheadedness
- Nausea
- Cold sweats
It is important to note that some people, especially women, may experience less typical or no apparent symptoms.
Diagnosis of coronary artery disease
During the visit, the doctor will review your medical history, ask you to describe your symptoms and listen to your heart with a stethoscope. Additionally, they may perform some further tests to obtain a more accurate diagnosis. Below is a list of tests that the doctor may recommend:
- Electrocardiogram (ECG): Records the heart’s electrical activity at rest.
- Stress test: Evaluates how the heart responds to physical exertion.
- Echocardiogram: Uses sound waves to create images of the heart.
- Coronary angiography: Provides detailed images of blood flow through the coronary arteries.
- Cardiac CT scan: Offers three-dimensional pictures of the heart and coronary arteries.
Treatment of coronary artery disease
The treatment of coronary artery disease may include invasive procedures aimed at restoring coronary blood flow, as well as lifestyle changes and medication.
1. Lifestyle changes:
- Healthy diet
- Regular exercise
- Quitting smoking
- Weight loss
- Stress management
2. Medications:
- Statins: Reduce cholesterol.
- Antiplatelets: Prevent platelets from sticking to the arteries.
- Anticoagulants: Prevent blood clots from forming in blood vessels.
- Beta-blockers: Allow the heart to work less hard (it will need less blood and oxygen).
- Calcium channel blockers: Help keep arteries open.
3. Invasive procedures:
- Coronary angioplasty: Restores the internal diameter of the coronary artery, improving blood flow to the heart and relieving disease symptoms.
- Coronary artery bypass surgery: Improves blood flow to the heart by creating a new route or bypass around the blocked artery.
Prevention of coronary artery disease
Prevention is key in the fight against coronary artery disease. Some preventive measures include:
- Maintaining a balanced, low-saturated-fat diet
- Exercising regularly
- Controlling weight
- Quitting smoking
- Managing stress
- Controlling blood pressure and cholesterol
- Managing diabetes
- Having regular medical check-ups
Living with coronary artery disease
If you have been diagnosed with coronary artery disease, this list of recommendations may be helpful:
- Follow the treatment plan prescribed by your doctor.
- Maintain a healthy lifestyle.
- Identify the warning signs of a heart attack.
- Attend all follow-up appointments.
- Consider joining a support group.

The importance of cardiac rehabilitation
Cardiac rehabilitation is a crucial component in the treatment of coronary artery disease that is often overlooked. This supervised programme includes the following steps:
- Adapted physical exercise.
- Education on healthy lifestyles.
- Psychological support.
- Stress management.
Cardiac rehabilitation has been shown to improve quality of life, reduce the risk of future cardiac events, and decrease mortality in patients with coronary artery disease.
The emotional impact of coronary artery disease
It is essential to recognise that coronary artery disease affects not only physical health but also emotional well-being. Many patients may experience:
- Anxiety about their future health.
- Depression.
- Fear of physical activity.
- Changes in personal relationships.
At HM Hospitals, we offer psychological support as an integral part of treating coronary artery disease helping people manage these emotional challenges.
Coronary artery disease in special populations
It is important to note that coronary artery disease can manifest differently in specific groups:
- Women Often present with atypical symptoms, which can lead to delayed diagnoses.
- Older adults May have more subtle presentations of the disease and a higher risk of complications.
- Diabetics Have a significantly higher risk of developing coronary artery disease and may have less obvious symptoms.
- People with chronic kidney disease also have an elevated risk and may require special monitoring.
At HM Hospitals, our specialists are trained to recognise and manage these unique presentations of coronary artery disease.
