How Coronary Artery Disease Develops: Causes and Risk Factors

What is Coronary Artery Disease?

Coronary artery disease is a heart condition. It happens when the blood vessels that supply your heart become narrow or blocked. Because of this, your heart may not get enough oxygen-rich blood. Over time, this can lead to chest pain, heart attacks, or other serious problems. According to the World Health Organization (WHO), coronary artery disease is one of the leading causes of death worldwide. Early detection and treatment can help you live a longer, healthier life.

Common Symptoms

Many people may not notice symptoms at first. However, as the disease gets worse, you might feel:

Chest pain or discomfort (angina), especially during activity

Shortness of breath

Fatigue or weakness

Pain in the neck, jaw, shoulder, or arm

Heart palpitations

Sometimes, the first sign is a heart attack. Therefore, it is important to know these symptoms and seek help if they appear.

Major Causes and Risk Factors

Coronary artery disease develops over many years. The main cause is a buildup of fatty deposits, called plaque, inside the arteries. This process is known as atherosclerosis. Several risk factors can increase your chances of developing this disease. For example:

High blood pressure

High cholesterol levels

Smoking

Diabetes

Obesity

Lack of physical activity

Unhealthy diet

Family history of heart disease

Older age

Even so, you can lower your risk by making healthy choices.

How Is It Diagnosed?

Doctors use several tests to diagnose coronary artery disease. First, they will ask about your symptoms and medical history. Next, they may perform a physical exam. Common tests include:

Electrocardiogram (ECG or EKG) to check your heart’s rhythm

Stress test to see how your heart works during activity

Blood tests to measure cholesterol and other markers

Coronary angiography to look at blood flow in your heart

CT or MRI scans for detailed images

With these tests, your doctor can find out how severe the disease is and plan the right treatment.

Treatment Options

Treatment for coronary artery disease depends on how serious it is. Often, doctors suggest a mix of lifestyle changes and medicines. In some cases, procedures or surgery may be needed. Treatment options include:

Medications to lower blood pressure, cholesterol, or prevent blood clots

Lifestyle changes such as a healthy diet and regular exercise

Angioplasty and stenting to open blocked arteries

Coronary artery bypass surgery for severe blockages

Because each person is different, your doctor will help choose the best plan for you.

Lifestyle Tips and Prevention

Although coronary artery disease is serious, you can take steps to lower your risk. For instance:

Eat a balanced diet rich in fruits, vegetables, and whole grains

Exercise regularly, at least 30 minutes most days

Quit smoking and avoid secondhand smoke

Maintain a healthy weight

Manage stress with relaxation techniques

Limit alcohol intake

Check your blood pressure and cholesterol regularly

By following these tips, you can help protect your heart and improve your overall health.

When to See a Doctor

If you notice chest pain, shortness of breath, or other warning signs, seek medical help right away. Even mild symptoms should not be ignored. Early treatment can prevent serious problems. In addition, regular check-ups are important, especially if you have risk factors for heart disease. Your doctor can guide you on the best steps for your heart health.
