What Is Coronary Artery Disease?

Coronary artery disease (CAD) happens when the blood vessels supplying your heart (coronary arteries) become narrowed or blocked.

This is usually due to a gradual build-up of fatty deposits called plaque inside the artery walls. Over time, this reduces blood flow to the heart muscle. If the blood supply becomes too limited, it can lead to chest pain, shortness of breath or a heart attack.

CAD is a progressive condition, but with early diagnosis and treatment, it can be well managed.

Coronary Artery Disease Causes

CAD develops gradually over time due to damage and narrowing of the coronary arteries, causing a build-up of cholesterol and fatty deposits

Risk Factors That Increase Your Risk:

Smoking

Sedentary lifestyle

Family history of heart disease

Increasing age

Chronic stress

These factors accelerate plaque formation and increase the risk of reduced blood flow to the heart.

Coronary Artery Disease Symptoms

Symptoms can vary from mild to severe, and some patients may not notice symptoms until the disease is more advanced. Common symptoms include:

  • Chest pain, pressure, or tightness (especially during exertion)
  • Shortness of breath
  • Fatigue or reduced energy levels
  • Reduced ability to exercise

Less Obvious Symptoms

Some patients may experience symptoms that are not clearly “heart-related,” such as:

  • Discomfort in the jaw, neck, shoulder, or arm
  • Indigestion-like chest discomfort
  • Nausea or sweating episodes
  • Fatigue/Tiredness

In women and diabetic patients, symptoms may sometimes be more subtle or atypical.

How Serious Is Coronary Artery Disease?

Coronary artery disease is one of the most common causes of heart attacks. Without treatment, plaque build-up can:

  • Progressively narrow the arteries
  • Suddenly rupture and form a blood clot
  • Block blood flow completely, causing a heart attack

The good news is that early detection and treatment can significantly reduce risk and improve outcomes.

How Is Coronary Artery Disease Diagnosed?

Several tests are used to assess heart function and identify blocked or narrowed arteries.

ECG (Electrocardiogram)

An ECG records the electrical activity of your heart.

It helps detect:

  • Irregular heart rhythms
  • Signs of previous or current heart strain
  • Possible heart attack changes

However, an ECG alone cannot show blocked arteries directly.

An echocardiogram uses ultrasound waves to create moving images of your heart.

It helps assess:

  • Heart pumping function
  • Heart valve structure and function
  • Areas of weakened heart muscle

It gives information about how the heart is working, but not detailed images of coronary artery blockages.

A CT coronary angiogram is a non-invasive scan that looks at the coronary arteries in detail.

It involves:

  • Injection of contrast dye through a vein
  • A CT scanner taking detailed images of the heart arteries

It helps detect:

  • Early plaque build-up
  • Narrowing of coronary arteries
    Patients at risk of significant blockage

This test is often used for screening or early assessment.

A coronary angiogram is a minimally invasive but accurate test to directly visualise the heart arteries.

It involves:

  • Inserting a thin tube (catheter) through the wrist or groin
  • Guiding it to the heart arteries
  • Injecting dye to clearly map blood flow

It helps identify:

  • Exact location and severity of blockages
  • Whether stenting or angioplasty is needed

In some cases, treatment (angioplasty and stent placement) can be performed during the same procedure.

Coronary Artery Disease Treatment in Singapore

Treatment depends on how severe the blockage is and your symptoms.

Lifestyle plays a major role in managing CAD:

  • Heart-healthy diet
  • Regular exercise (as advised by your doctor)
  • Smoking cessation
  • Weight management
  • Controlling blood pressure, cholesterol, and diabetes

Your doctor may prescribe medications to:

  • Lower cholesterol
  • Control blood pressure
  • Reduce strain on the heart
  • Prevent blood clots

These help slow disease progression and reduce risk of heart attacks.

If significant blockages are found, angioplasty may be recommended.

This involves:

  • Opening narrowed arteries using a balloon
  • Placing a stent to keep the artery open
  • Improving blood flow to the heart

It is a minimally invasive procedure performed through a small access point.

Read More About Angioplasty

In more severe or complex cases, bypass surgery may be considered.

This is typically recommended when:

  • Multiple arteries are severely blocked
  • Angioplasty is not suitable

Can Coronary Artery Disease Be Prevented or Controlled?

While CAD cannot always be completely reversed, it can often be:

  • Controlled effectively
  • Stabilised with treatment
  • Slowed significantly with lifestyle changes

Early diagnosis is key to preventing complications.

Living With Coronary Artery Disease

Many patients continue to live full and active lives with proper treatment.

Ongoing care may include:

  • Regular heart check-ups
  • Monitoring cholesterol and blood pressure
  • Adjusting medications
  • Lifestyle improvements
  • Periodic heart imaging or stress testing

The goal is long-term heart protection and risk reduction.

When Should You See a Cardiologist?

You should consider a cardiac evaluation if you have:

  • Chest discomfort or pressure
  • Shortness of breath
  • Reduced exercise tolerance
  • Multiple risk factors such as diabetes or high blood pressure
  • A family history of heart disease

Early assessment can help detect issues before they become serious.

Dr Pinakin's Approach to Coronary Artery Disease Management

Patients often value Dr Pinakin’s approach because it focuses on:

Understanding Your Individual Risk

Assessing factors such as cholesterol, blood pressure, diabetes, family history, and lifestyle habits.

Explaining Results Clearly

Helping patients understand their test results, treatment options, and what they mean for long-term heart health.

Personalising Treatment

Tailoring care to the individual, from lifestyle changes and medication to angioplasty when appropriate.

Frequently Asked Questions

It can often be stabilised and slowed, and in some cases partially improved with treatment and lifestyle changes.

Yes. Many people with coronary artery disease live long, active lives. With proper treatment, lifestyle changes, and regular follow-up, the condition can be well controlled and the risk of complications reduced.

Not always. Many patients are managed with medication and lifestyle changes alone.

Yes, but exercise should be guided by your doctor based on your condition.
