Ischaemic heart disease and atherosclerotic coronary artery disease are two of the most common cardiovascular diseases, affecting millions of people worldwide. Both conditions can have severe consequences on an individual’s overall health and quality of life, making early detection and prevention strategies essential.

By raising awareness about these diseases, we aim to empower individuals to make informed choices regarding their heart health and encourage positive lifestyle changes that can significantly reduce the risk of developing these life-threatening conditions.

Understanding ischaemic heart disease

Ischaemic heart disease, also known as coronary heart disease, is a condition where the blood supply to the heart muscle is reduced or blocked. This can be caused by a buildup of fatty deposits (atherosclerosis) in the coronary arteries. 

Causes of ischaemic heart disease

• Atherosclerosis. The primary cause of ischaemic heart disease is atherosclerosis, which is the narrowing and hardening of the arteries due to plaque buildup.
• High blood pressure. Hypertension can contribute to the development of atherosclerosis by damaging the artery walls and accelerating plaque buildup.
• High cholesterol. Elevated levels of low-density lipoprotein (LDL) cholesterol can lead to the formation of plaque in the arteries.

Risk factors for ischaemic heart disease

• Age. The risk of developing ischaemic heart disease increases with age, particularly for men over 45 and women over 55.
• Family history. A family history of heart disease increases the risk of developing the condition.
• Smoking. Tobacco use is a major risk factor, as it can damage blood vessels and increase the risk of atherosclerosis.
• Obesity. Excess body weight can contribute to high blood pressure and high cholesterol levels, increasing the risk of ischaemic heart disease.
• Diabetes. People with diabetes are at a higher risk of developing heart disease due to elevated blood sugar levels, which can damage blood vessels.

Recognising the symptoms of ischaemic heart disease

Symptoms of ischaemic heart disease can vary, but they often include:

• Chest pain (angina). This is a feeling of tightness, heaviness, or pressure in the chest, often brought on by physical activity or stress.
• Shortness of breath. This may occur during physical activity or at rest.
• Fatigue. Feeling tired or weak can be a sign of reduced blood flow to the heart.
• Heart palpitations. An irregular or rapid heartbeat may be a symptom of ischaemic heart disease.

Treatment options for ischaemic heart disease

There is no cure for ischaemic heart disease, but various treatment options can help manage symptoms and reduce the risk of complications. These may include:

• Lifestyle changes: Adopting a healthy lifestyle can help prevent and manage ischaemic heart disease. This may involve quitting smoking, eating a balanced diet, maintaining a healthy weight, and engaging in regular exercise.
• Medications: Various medications can help control blood pressure, cholesterol levels, and blood sugar levels, reducing the risk of ischaemic heart disease.
• Surgical procedures: In some cases, medical procedures such as angioplasty, stenting, or coronary artery bypass grafting may be necessary to improve blood flow to the heart.

Understanding atherosclerotic coronary artery disease

Atherosclerotic coronary artery disease (CAD) is a specific type of ischaemic heart disease caused by the buildup of plaque in the coronary arteries. This section will discuss the relationship between CAD and ischaemic heart disease.

The link between ischaemic heart disease and CAD

Atherosclerotic coronary artery disease is the most common cause of ischaemic heart disease. The plaque buildup in the coronary arteries restricts the blood flow to the heart muscle, leading to a reduction in oxygen and nutrients. Over time, this can result in damage to the heart muscle and the development of ischaemic heart disease.

Preventing and managing atherosclerotic coronary artery disease

The prevention and management of atherosclerotic coronary artery disease largely mirror the strategies for ischaemic heart disease, as the two conditions are closely related. Key measures include:

• Lifestyle changes. Adopting a heart-healthy lifestyle is essential for preventing and managing atherosclerotic coronary artery disease. This includes a balanced diet rich in fruits, vegetables, whole grains, and lean proteins; regular exercise; maintaining a healthy weight; and avoiding smoking and excessive alcohol consumption.
• Medications. Medications such as statins, which help lower cholesterol levels, may be prescribed to reduce the risk of atherosclerotic plaque formation. Blood pressure and blood sugar control are also crucial for managing CAD.
• Monitoring and follow-up care. Regular check-ups with your healthcare professional can help detect early signs of atherosclerosis and ensure appropriate treatment is initiated promptly.

Protect your heart for a healthier future

Ischaemic heart disease and atherosclerotic coronary artery disease are major health concerns in the UK and worldwide. By understanding the causes, symptoms, and treatment options for these conditions, we can take the necessary steps to protect our hearts and promote a healthier future.

Remember, prevention is always better than cure, so adopting a heart-healthy lifestyle is the best way to reduce your risk of developing these life-threatening diseases.
