Understanding Coronary Artery Disease (CAD)

What is Coronary Artery Disease?

Coronary Artery Disease (CAD) is a condition where the coronary arteries, which supply blood to the heart, become narrowed or blocked due to the buildup of plaque. Plaque is a combination of fat, cholesterol, calcium, and other substances that accumulate on the artery walls—a process known as atherosclerosis. This narrowing restricts blood flow, making it difficult for the heart to get the oxygen-rich blood it needs to function effectively.

Over time, CAD can weaken the heart muscle, leading to symptoms like chest pain (angina), shortness of breath, and even heart attacks. As one of the most common types of heart disease, CAD is a leading cause of mortality, but with appropriate diagnosis and treatment, many people can manage and significantly reduce their risks.

 

 

What Causes Coronary Artery Disease?

Several factors contribute to the development of CAD, and often, these risk factors are interlinked:

• High Blood Pressure: Hypertension can damage the inner walls of arteries, making it easier for plaque to build up.
• High Cholesterol Levels: Elevated levels of LDL (“bad”) cholesterol are associated with plaque formation.
• Diabetes: People with diabetes are at higher risk of CAD due to the effects of high blood sugar on the blood vessels.
• Smoking: Smoking damages the blood vessels and accelerates plaque buildup.
• Family History: Genetic predisposition can play a role in a person’s likelihood of developing CAD.
• Lifestyle Factors: Lack of exercise, unhealthy diet, and high-stress levels can all contribute to the onset of CAD.

 

Recognising Symptoms of Coronary Heart Disease

The symptoms of Coronary Heart Disease can vary, but some common warning signs include:

• Chest Pain or Discomfort (Angina): This may feel like pressure, tightness, or heaviness in the chest, often triggered by physical or emotional stress.
• Shortness of Breath: A reduced blood supply may make it difficult to breathe comfortably, especially with physical exertion.
• Fatigue: Some patients with CAD may feel unusually tired or fatigued, even with minimal physical activity.
• Heart Attack: In severe cases, a blocked artery can lead to a heart attack, characterised by intense chest pain, sweating, nausea, and lightheadedness.

Diagnosing Coronary Artery Disease

Early diagnosis is essential for effective CAD management. Several diagnostic tools and tests help cardiologists identify the presence and severity of CAD:

1. Coronary Angiography: A key diagnostic tool, coronary angiography uses X-ray imaging to view the arteries. A contrast dye is injected through a catheter to highlight any blockages or narrowing.
2. Electrocardiogram (ECG): This test records the heart’s electrical activity and can reveal past heart attacks or ongoing ischemia (lack of blood flow).
3. Stress Test: This involves monitoring the heart’s response to physical exertion, helping identify blood flow issues linked to CAD.
4. Blood Tests: Blood tests can identify high cholesterol, blood sugar, and other markers associated with heart disease.

These diagnostic options help guide cardiologists in developing tailored treatment plans for their patients.

 

 

Treatment Options for Coronary Artery Disease

Managing CAD often involves a combination of lifestyle changes, medications, and in some cases, surgical procedures:

1. Lifestyle Modifications: Quitting smoking, following a heart-healthy diet, managing stress, and engaging in regular exercise are foundational to CAD management.
2. Medications: Various medications can help control risk factors, including:
   • Statins to lower cholesterol levels
   • Antiplatelet medications (like aspirin) to reduce blood clot risk
   • Beta-blockers and ACE inhibitors to manage blood pressure and heart strain
3. Interventional Procedures:
   • Percutaneous Coronary Intervention (PCI): Also known as coronary angioplasty, PCI is a minimally invasive procedure that involves placing a stent to widen narrowed arteries.
   • Coronary Artery Bypass Grafting (CABG): In more severe cases, this surgery involves redirecting blood flow around a blocked artery using a healthy blood vessel from another part of the body.

Preventing Coronary Artery Disease

Understanding prevention is key. Simple, proactive steps can help reduce the risk of developing CAD:

• Maintain a Healthy Diet: Emphasise foods low in saturated fats, salt, and added sugars. A Mediterranean-style diet rich in fruits, vegetables, whole grains, and healthy fats is beneficial for heart health.
• Regular Exercise: Aim for at least 30 minutes of moderate physical activity most days of the week.
• Routine Checkups: Regular screenings for blood pressure, cholesterol levels, and blood sugar can help catch risk factors early.
• Stress Management: Chronic stress can impact heart health, so practices like mindfulness, yoga, and other relaxation techniques are recommended.

For patients at high risk, GPs may recommend medications or lifestyle changes even if CAD symptoms are not yet present.
