Diabetes is one of the most common health conditions worldwide. It is much more than something that affects blood sugar levels in the body. Over time, it can quietly damage blood vessels throughout the body, especially those supplying the heart. This makes people with diabetes two to four times more susceptible to developing Coronary Artery Disease (CAD)

Coronary artery disease (CAD) is a common type of heart disease that affects the main blood vessels that supply blood to the heart. A reduced blood flow to the heart muscle is due to the buildup of fats, cholesterol and other substances in and on the artery walls, which is called plaque. It narrows the arteries and prevents the circulation of blood, which can cause coronary artery disease

Coronary artery disease often develops over many years. Symptoms are due to lack of blood flow to the heart and may include chest pain and shortness of breath. A complete blockage of blood flow can cause a heart attack. Early screening, timely diagnosis and appropriate treatment can dramatically reduce the risk of heart attacks and other serious complications.

 If left untreated, CAD can lead to:

• Angina (chest pain or discomfort)
• Heart attack
• Heart failure
• Irregular heart rhythms
• Sudden cardiac death

Symptoms of CAD are:

• Chest discomfort during activity
• Breathlessness
• Palpitations
• Unexplained fatigue
• Dizziness or fainting
• Swelling of the legs
• Reduced ability to perform routine activities

These symptoms may appear mild, but they indicate underlying heart disease, especially in people with diabetes.

Never ignore warning signs like

Although symptoms may be subtle, seek medical attention if you notice:

• Chest discomfort or pressure
• Pain spreading to the jaw, shoulder, arm or back
• Shortness of breath
• Fatigue with minimal activity
• Unexplained sweating
• Nausea
• Dizziness or fainting
• Reduced exercise tolerance

Even mild symptoms deserve evaluation in people with diabetes.

Why are people with diabetes at higher risk?

Diabetes accelerates damage to blood vessels. Some of the sedentary and lifestyle damages are:

• Persistently high blood sugar level
• Increased inflammation
• Higher cholesterol and triglycerides
• High blood pressure
• Insulin resistance
• Damage to nerves (diabetic neuropathy)
• Obesity
• Smoking

These factors can occur individually or together, greatly increasing the likelihood of CAD

What is Silent CAD?

One of the biggest challenges in diabetes is Silent Coronary Artery Disease. Many diabetics do not experience the classic warning signs of heart disease. A person may continue normal activities despite significant artery blockage. Heart evaluation is especially important if you have diabetes, especially a person above 40 years old

 Who should consider early CAD screening?

• Diabetes for more than 10 years
• High blood pressure
• High cholesterol\Smoking history
• Obesity
• Family history of heart disease
• Kidney disease
• Previous stroke or peripheral artery disease

How is Early CAD Detected?

The cardiologist will decide which investigation is appropriate based on your symptoms and risk factors

The healthcare professional may recommend:

- Clinical Evaluation

• Medical history
• Physical examination
• Blood pressure assessment
• Body weight and waist circumference

- Blood Tests

• Blood sugar (HbA1c)
• Lipid profile
• Kidney function

- Cardiac biomarkers when indicated

- Heart Investigations

• Electrocardiogram (ECG)
• Echocardiogram
• Treadmill Stress Test (TMT)
• Stress Echocardiography
• Nuclear Stress Test
• CT Coronary Calcium Score
• CT Coronary Angiography
• Coronary Angiography if necessary

Early Detection is important to:

• Prevent heart attacks
• Reduce the risk of sudden cardiac events
• Begin treatment early
• Improve long-term heart function
• Reduce hospital admissions
• Improve quality of life and increase life expectancy

Important tips for cardiovascular health include:

• Maintain target blood sugar levels
• Keep blood pressure under control
• Manage cholesterol with diet and medications if prescribed
• Exercise for at least 150 minutes each week
• Eat a heart-healthy diet rich in vegetables, fruits, whole grains, lean proteins, and healthy fats
• Avoid smoking and limit alcohol consumption
•  Maintain a healthy body weight
• Take medications exactly as prescribed
•  Attend regular health check-ups and cardiovascular assessments
