When it comes to heart health, early detection can save lives. Coronary artery disease creeps in silently and is the leading cause of heart attacks in the US. But, do you know what the good thing is? CAD is detectable and curable when identified early, and knowing what tests are available for early, safe detection is crucial. 

Whether you are experiencing symptoms or just want to be concerned because of your family history, getting tested for CAD is your early line of defence. At ViaScan, we specialize in noninvasive imaging techniques to help you catch the disease early, before the symptoms start haunting you. Let’s explore the tests for coronary artery disease, why early testing is important, and how CAD is tested.  

What is coronary artery disease?

CAD occurs when blood vessels that supply blood to the heart are blocked with plaque buildup. This calcium deposition will completely or partially block the coronary arteries, reducing the supply of blood, ultimately leading to chest pain and heart attacks.

Coronary artery disease doesn’t come with full-blown symptoms. Therefore, early screening or a coronary CT scan can help you identify the extent of blockages, especially if you fall into the following categories:

  • Have a family history of heart disease
  • Overweight or obese
  • High blood pressure
  • High cholesterol
  • Diabetes 
  • Smoking

The crucial part is that you may not even experience the symptoms until it’s too late. Therefore, getting tested early when you can will allow you to make early medical interventions.

How is coronary artery disease tested?

There are several ways to detect CAD, but the modern and safe way is noninvasive coronary CT scans, which are leading the way.

Coronary Calcium Scan

This quick and noninvasive scan uses an advanced CT scanner to measure the amount of calcium deposited in the walls of arteries. The calcium score indicates the level of risk your heart faces and helps identify early signs of plaque buildup. Coronary calcium scans can also be used for those who smoke or do not exhibit heart disease symptoms to determine their risk of developing coronary heart disease.

Blood Tests

Blood testing can measure cholesterol and blood sugar. A high-sensitivity test for C-reactive protein (CRP) detects a protein associated with inflammation in the arteries.

Electrocardiogram

This brief test examines the heart’s electrical activity. It displays the heart’s rhythm. Electrodes are sticky patches that adhere to the chest and occasionally the arms and legs. The electrodes are connected via wires to a computer, which prints or shows the test findings. If you have had or are experiencing a heart attack, the ECG signal patterns can reveal it.

Nuclear Stress Test

Stress tests examine your heart while it is beating rapidly and working at a high rate. Your doctor may prescribe medication to temporarily increase your heart’s workload if you have a medical condition that keeps you from exercising. Your healthcare professional will use an ECG or another imaging test to look for insufficient blood flow to your heart muscle. As you exercise, an ECG will track the electrical activity of your heart.

Heart CT scan

This CT scan of the heart will identify and show blockages in the arteries, as well as detect the extent of calcium deposition. Arteries might constrict due to calcium deposits. During the scan, dye is occasionally administered intravenously. This dye will flow through the arteries, allowing your doctor to clearly visualise the blood flow and take detailed images of the carotid arteries. This scan is known as a CT coronary angiography if dye is utilized.

A safer way to diagnose coronary artery disease?

Coronary artery disease comes with no warning signs. Therefore, if you are experiencing symptoms such as:

  • Shortness of breath 
  • Sudden chest pain
  • Palpitations 
  • Irregular heartbeat
  • Dizziness after minimal work

Don’t delay a heart CT scan. But what is the risk-free and safest way to detect coronary artery disease? A quick and noninvasive coronary CT scan at Viascan. We specialize in low-dose CT scans to provide you with an accurate diagnosis within a few minutes.

In the USA, the most common type of heart disease is Coronary artery disease (CAD), and according to the CDC (Centres for Disease Control & Prevention), it is affecting 1 out of 20 (About 5%) Americans aged 20 and older.

Coronary artery disease, the leading cause of heart attacks, does not always occur with crushing chest pain or collapse. In fact, sometimes it comes silently, and many people don’t even know they have it for years until it progresses to a dangerous stage. Knowing the symptoms early and getting a CT heart scan is a key to saving your life.

At ViaScan, we have helped thousands of people diagnose heart disease with our non-invasive scans before it becomes untreatable. Let’s discuss how early screening can help in diagnosing issues before symptoms appear, Allowing you to take early medical interventions. 

What is Coronary Artery Disease?

CAD Occurs when plaque, composed of fats, calcium or cholesterol, builds up in your coronary arteries, Which carry Nutrients-Rich blood to your heart. This Condition, in which your arteries become blocked or narrowed due to the deposition of plaque, Reducing blood flow to the heart is called atherosclerosis.

This will eventually lead to chest pain or heart failure. If arteries are completely blocked, you are at risk of a heart attack. but can you stop coronary artery disease from progressing? Yes, Even after atherosclerosis develops. You can slow its progression with early diagnosis, and certain healthy lifestyle changes.

  • Regular Exercise
  • Eat a balanced diet
  • Quit smoking, and alcohol consumption
  • Weight loss
  • Manage cholesterol levels
  • Manage diabetes if you have it.

However, if you are not taking preventive care, the plaque will continue to grow. It ultimately will block your arteries completely, and this is when the symptoms of coronary artery disease begin to show.

Common symptoms of Coronary Artery Disease

Atherosclerosis develops slowly, So people often do not experience any symptoms until it completely blocks their arteries. The most common coronary artery disease symptoms you may experience include:

1. Chest pain

The most common sign of CAD is Angina, Which occurs when the heart does not get enough oxygen. This deprivation of oxygen leads to chest pain or angina. this may feel like pressure in the chest area, accompanied by tightness or pressure. People often experience it while exercising and feels better after taking a rest. However, if it remains consistent, you must consider it a warning and head for a quick heart CT scan.

2. Shortness of breath

This often feels like you are not getting enough air while breathing. Even a slight workout leaves you breathless; This is your sign to consider a coronary scan, As your heart may not be pumping blood efficiently.

3. Fatigue or Tiredness

When you feel a loss of energy even after completing small daily tasks. This is a sign that your heart is not receiving enough nutrient-rich blood, Which affects its functioning. Eventually your body will not receive enough nutrients, making you feels tired all day.

4. Cold Sweats or Dizziness

You may feel dizzy during physical activity or experience cold sweats. These may not be directly related to heart related disease. But are major red flags if they occur during angina or chest pain.

5. Heart Palpitations

6. Other symptoms

You may experience pain or discomfort in areas such as the back, arms, neck, or jaw, or shoulders. Womens are more likely to experience pain in places other than the chest region.

How early screening can help?

Most people don’t even know they have CAD (coronary artery disease) until they experience a heart attack. However, early scanning and diagnosis with a CT angiogram can help:

  • Detect deposition early
  • Score your coronary calcium levels
  • Identify potential blockages

This will give you clarity and a head start for treatment long before the symptoms appears.
