Heart imaging is a valuable technique for detecting and treating heart disease. In Singapore, coronary artery scans are an essential tool for cardiologists, providing valuable insights into heart disease. This article discusses the various aspects of heart imaging in Singapore, with a focus on coronary artery scans, technological advancements, who needs these scans, and how to prepare for them. It also lists some of Singapore’s top heart imaging clinics.

Coronary Artery Scans: What They Are and Why They Matter

Coronary artery scans are an important tool for the early detection and treatment of heart disease. These specialist scans, which show calcium deposits in the coronary arteries, are critical in determining an individual’s risk of developing significant cardiovascular diseases. Here, we look at what these scans are, why they are important, and how they can affect heart health care.

What’s it For?

Coronary artery scans, commonly known as coronary artery calcium (CAC) scans, are sophisticated imaging techniques used to detect calcium deposits in the coronary arteries. These arteries are important because they feed blood to the heart muscle.

The presence of calcium in these arteries is an important signal. Calcium deposits are often indicative of plaque buildup, which is a key risk factor for coronary artery disease, one of the leading causes of heart-related illnesses and fatalities.

Detecting calcium deposits early with these scans might provide critical insights into one’s cardiovascular health, perhaps leading to earlier intervention and control of heart disease risks.

How Coronary Artery Scans Work

These scans employ computed tomography (CT) technology, specifically the specialist type known as cardiac CT. A coronary artery scan involves a patient laying on a table that slides inside a large, donut-shaped machine. The CT scanner takes numerous X-ray images, which are then combined to create a detailed cross-sectional view of the coronary arteries.

Importance of Coronary Artery Scans

Coronary artery scans are useful because:

  • Recognize the early symptoms of coronary artery disease (CAD).
  • Assist with predicting the likelihood of heart attacks.
  • Provide therapy recommendations to patients with known or suspected heart disease.
  • Help to monitor the effectiveness of therapy and lifestyle changes.

When Are Coronary Artery Scans Used?

Coronary artery scans are frequently conducted on persons who have risk factors for heart disease or are experiencing symptoms like chest pain, shortness of breath, or dizziness. These scans are very beneficial in recognizing coronary artery disease before it advances to more serious issues like a heart attack.

Advancements in Heart Imaging in Singapore: Technologies and Facilities

Singapore has established itself as a leading center for medical innovation, and heart imaging is no exception. The country has achieved significant advances in heart imaging technology, providing patients with accurate and consistent results.

Cutting-Edge Technologies

Heart imaging in Singapore utilizes cutting-edge technologies, such as:

  • Multidetector Computed Tomography (MDCT): This technique offers faster scanning with higher image resolution, allowing cardiologists to detect even trace amounts of calcium in the coronary arteries.
  • Magnetic Resonance Imaging (MRI): While commonly used for a variety of heart-related conditions, cardiac MRI can offer detailed images of the heart’s architecture and function, enhancing coronary artery imaging.
  • Echocardiography: Echocardiography is a technique that uses ultrasonic waves to create images of the heart, which disclose information about its function and architecture.

Leading Facilities in Singapore

Singapore boasts some of the best medical facilities for cardiac imaging. These hospitals and clinics are equipped with cutting-edge technology and staffed by highly skilled cardiologists and radiologists, resulting in precise diagnoses and treatment. Here are some of the best facilities that offer cardiac imaging in Singapore:

  • National Heart Centre Singapore (NHCS) is a premier cardiac care institution that provides a wide range of heart imaging procedures, including coronary artery scans.
  • Gleneagles Hospital is a premium hospital that is well-known for delivering comprehensive cardiac care services, including cutting-edge heart imaging equipment.
  • Mount Elizabeth Hospital is another private hospital in Singapore that offers advanced heart imaging. It is well-known for offering superior cardiac treatment.

Who needs a Coronary Artery Scan? Identifying Risk Factors and Symptoms

Coronary artery scans are not typically included in routine medical exams. Instead, they are recommended for patients who have certain risk factors or symptoms of heart disease. Understanding who need these scans ensures that they are utilized effectively to identify and prevent heart disease.

Risk Factors for Coronary Artery Disease

Certain risk factors increase the likelihood of coronary artery disease, including:

  1. Age: People over 40 are at a greater risk.
  2. A family history of heart disease can increase the risk.
  3. Smoking causes plaque accumulation in the blood arteries.
  4. High blood pressure puts additional stress on the arteries.
  5. High cholesterol promotes plaque growth.
  6. Diabetes increases the risk for coronary heart disease.

Symptoms That Indicate the Need for a Coronary Artery Scan

While some risk factors, such as high cholesterol, hypertension, and a family history of heart disease, can predispose people to coronary artery disease, certain symptoms may warrant a coronary artery scan to more accurately assess heart health. Symptoms include:

  • Chest Pain (Angina): One of the most recognizable symptoms, chest pain or discomfort, also known as angina, can suggest reduced blood flow to the heart muscle, which is usually caused by coronary artery disease.
  • Shortness of Breath: Shortness of breath, particularly during physical activity or exercise, can indicate that the heart is unable to pump adequately due to clogged coronary arteries.
  • Fatigue: An unusual or chronic sense of tiredness or exhaustion during previously tolerable activity can indicate a decrease in cardiac output, which could be caused by the heart not obtaining enough oxygen-rich blood.
  • Dizziness or lightheadedness: These symptoms may occur as a result of a decrease in blood supply to the brain, which is frequently caused by inadequate blood flow from the heart and may indicate underlying coronary difficulties.
  • Heart palpitations: A fast, fluttering, or hammering heartbeat may suggest irregular heart rhythms caused by coronary artery disease or other cardiac disorders that impair the heart’s efficiency.

When these symptoms appear, particularly in those with known risk factors or a family history of heart disease, a coronary artery scan can be an important diagnostic tool for determining the amount of coronary calcification and guiding future treatment or preventive actions.

Getting Ready for Heart Imaging in Singapore: Tips for a Smooth Process

If you have a coronary artery scan or other heart imaging procedures scheduled, proper preparation can help the experience go more easily and stress-free. Here are some tips to help you prepare for your heart imaging appointment in Singapore.
