Our Cardiac Screenings

As a specialized cardiovascular care center, we offer an extensive range of tests and screenings to give you the most accurate, comprehensive diagnosis. Some of these include: 

  • Treadmill Stress Test
  • Nuclear Stress Test
  • Carotid Ultrasound
  • Echocardiogram
  • EKG
  • Cardiac Amyloid Imaging
  • Genetic Testing

Treadmill Stress Test

A treadmill stress test is a cardiovascular test that measures how well your heart works during exercise. It involves walking on a treadmill while your heart’s activity and blood pressure are monitored. This test can help determine your functional capacity and assess the risk of coronary artery disease (CAD).  

Here’s what happens during a treadmill stress test:  

  • Electrodes: A technician attaches sticky patches called electrodes to your chest, wrists, and sometimes ankles. The electrodes are connected to an ECG monitor that tracks your heart’s electrical activity.  
  • Exercise: You walk on the treadmill, starting at a relaxed pace, gradually increasing the speed and incline.  
  • Monitoring: Your heart rate, blood pressure, and breathing are monitored. The test continues until you reach a target heart rate, experience chest pain, or have other concerning symptoms.  
  • Recovery: After the test, you’ll have a recovery period of at least six minutes.  

 

A treadmill stress test usually takes about an hour, including prep time. Abnormal results may indicate coronary artery disease, heart rhythm abnormalities, or other cardiovascular conditions. 

Nuclear Stress Test

A nuclear stress test may be recommended if you have symptoms of a heart condition, such as: Chest pain or discomfort, shortness of breath, irregular or rapid heartbeat, and dizziness or lightheadedness.  

A nuclear stress test can help diagnose and treat heart conditions, including:  

  • Coronary artery disease: A nuclear stress test can diagnose coronary artery disease and show how severe it is. It can also help determine how well treatment is working.  
  • Congestive heart failure: A nuclear stress test can help evaluate reversible causes of congestive heart failure.  
  • Exercise program or surgery: A nuclear stress test can help determine if you are at high risk for heart disease or complications before starting an exercise program or having surgery.  
  • Other conditions that a nuclear stress test can help with include: Aortic dissection, Aortic stenosis, Arrhythmia, Heart infection, Pulmonary embolism, and Pulmonary hypertension.  

 

A nuclear stress test is generally safe for older adults. If your doctor recommends the test, they can tell you why they consider it appropriate for you and the possible risks.  

Carotid Ultrasound

A carotid ultrasound, also known as a carotid duplex, is a painless and safe imaging technique that uses sound waves to assess the carotid arteries and blood flow to the brain. It can help diagnose carotid artery stenosis, which is a narrowing of the carotid arteries that can increase the risk of stroke.  

A carotid ultrasound can help identify: 

  • Carotid artery stenosis: Narrowing of the carotid arteries that can increase your risk of stroke. 
  • Atherosclerotic plaque: Buildup of plaque in your carotid arteries, which can cause clots to form and increase the risk of stroke.  
  • Blood flow: How well blood is traveling through your carotid arteries.  

 

A doctor may recommend a carotid ultrasound if you have:

  • A recent stroke or transient ischemic attack (TIA), also known as a mini-stroke. 
  • A medical condition that increases the risk of stroke, such as high blood pressure, high cholesterol, diabetes, or a family history of stroke. 
  • An unusual sound in the carotid arteries, called a bruit.  

 

During a carotid ultrasound, you lie on your back while the technician applies a water-based gel to your neck and moves a transducer over the area. The transducer sends sound waves into the arteries, which bounce off the blood vessels to create images.  

Echocardiogram

An echocardiogram is a medical imaging test that uses ultrasound waves to create images of your heart. It allows healthcare providers to assess your heart’s structure and function, including the size and shape of your heart, the condition of your heart valves, and the efficiency of blood flow. This test is non-invasive and typically performed in a hospital or outpatient setting. It can help diagnose various heart conditions, monitor heart health, and guide treatment decisions. If you have more specific questions about echocardiograms or heart health, feel free to ask!

What can I expect during a transthoracic echocardiogram (TTE)?

A TTE takes about an hour. A sonographer or other healthcare provider will:

  1. Have you lie down on an exam table.
  2. Attach small patches called electrodes to different areas on your chest to record your heart rate and rhythm.
  3. Squirt a special gel onto your skin that helps transmit sound.
  4. Press a transducer (ultrasound wand) against your skin and move it around. A transducer looks like a microphone. It sends the sound waves and picks up the echoes.
  5. Ask you to hold still, change positions or breathe in certain ways to obtain different or better pictures.

 

Why do I need a transthoracic echocardiogram?

Healthcare providers use TTE in many ways. The test can:

  • Assess heart health before or after diagnosis and treatment.
  • Identify the cause of certain symptoms.
  • Screen for and diagnose possible medical conditions.

 

TTE can evaluate heart health by:

  • Checking your heart valves.
  • Determining how well your heart is pumping blood.
  • Measuring blood pressure and how quickly blood is flowing through your heart.
  • Measuring the size and shape of your heart’s chambers.

 

The test can identify causes of cardiac-related symptoms, such as:

 

TTE is useful to screen for, diagnose or follow up on specific medical conditions, including:

Electrocardiogram (EKG)

An EKG, also known as an electrocardiogram, is a simple and painless test that records electrical signals in the heart. Our machines will translate the electrical signs into a wave pattern that our experts will then interpret for signs of irregular heart rhythms, blocked/narrowed arteries, or a heart attack. These can also be used to test whether a treatment is working properly.

Cardiac Amyloid Imaging

Cardiac Amyloid Imaging is an examination that detects amyloid deposits in the heart. Amyloids are an unstable version of Transthyretin, a normal transport protein produced by the liver. Over time, amyloids can build up in the heart muscle, causing the heart walls to thicken and become stiff. This buildup causes the heart to not pump correctly, which could lead to additional heart complications. Cardiac Amyloidosis can also lead to abnormal heartbeats called arrhythmias. 

With this imaging test, a radioactive tracer enters the bloodstream through an IV. The tracer collects in areas where the heart muscle has abnormal protein deposits. This is picked up with our imaging machines, which allow our doctors to diagnose and monitor Cardiac Amyloidosis.

Genetic Testing

Genetic testing allows our specialists to discover if patients have a genetic alteration that could lead to an inherited heart condition. Some cardiovascular diseases, such as arrhythmic disorders, can be passed along genetically. If you or your partner have a heart disease or familial history of a heart condition, genetic testing allows you to make educated decisions on the next steps of your family planning.
