Why choose Liberty Hospital Heart Center for cardiac testing?

When minutes matter most, Liberty Hospital Heart Center provides expert heart care close to home. Liberty Hospital Heart Center offers on-site diagnostics in our accredited echocardiography, nuclear medicine and vascular labs. Our cardiac testing services, combined with the multi-disciplinary strengths of our board-certified heart specialists, ensure your heart is in the right place when you’re at Liberty Hospital.

Our diagnostic testing services are available 24/7. In addition to blood testing, our cardiac testing services include:

Cardiac calcium score screening/test

A calcium (coronary) score screening/test is a CT scan of the heart that detects calcium build-up in the coronary arteries. It is available for $50, and no insurance is needed.

Calcium buildup can narrow your arteries and increase your risk of heart disease, so early diagnosis is key to preventing heart attacks and worsening heart disease. The calcium scoring scan will provide a number (or score) that relates to the amount of calcium deposits seen in your heart’s arteries. The higher the score, the more extensive the accumulation of plaque in your arteries. Calcium score guide:

0: The scan is not picking up any calcium deposits at this time.

1-100: Speak to your primary-care physician about heart disease prevention.

100-499: Speak to a cardiologist about heart disease prevention and any additional treatment needed.

500 or higher: You have significant calcium build-up and should seek care from a cardiologist as soon as possible.

This exam is not recommended for patients who are pregnant or claustrophobic. It is also not recommended for patients who have known coronary artery disease (e.g., have had a heart attack, angioplasty/stent or bypass surgery) or patients who have metallic objects in the heart (e.g., mechanical heart valves, pacemaker wires, stents, etc.).

Cardiac imaging tests

Common cardiac imaging tests include chest x-rays and ultrasounds, along with cardiac CT scans and MRIs. Liberty Hospital Heart Center is equipped with:

  • 160-slice CT scanner
  • Magnetic resonance imaging (MRI)
  • Nuclear medicine
  • PET/CT scanning
  • Chest ultrasound
  • Chest X-rays


This ultrasound test is used to detect abnormalities of the chambers and heart valves, murmurs, wall motion of the ventricle and possibly fluid surrounding the heart. Accredited through Intersocietal Accreditation Commission in Echocardiography.

Electromyography (EMG)

An EMG is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.

Electrocardiograms (EKG)

This test is used as a screening tool in diagnosing cardiac electrical abnormalities, such as a heart attack. An EKG records the electrical activity of the heart over time.

Holter monitors

This is a small portable device used for continuously monitoring the electrical activity of the heart for 24 hours or more. Its extended recording period is sometimes useful for observing occasional cardiac irregularities arrhythmias that would be difficult to identify in a shorter period of time. Liberty Hospital offers 24-hour and 48-hour monitors.

Nuclear stress testing

This test helps determine how the heart works during physical activity. As your body works during any physical exertion, it requires more oxygen and energy. To meet this demand, the heart beats faster and harder. The stress test shows if your heart receives enough blood from its own arteries to work harder, safely.

Stress echoes

A stress echocardiogram is usually done to rule out coronary artery disease. The test is generally conducted on a treadmill. For patients who cannot exercise on a treadmill, the test involves use of a medicine called dobutamine to evaluate coronary artery disease.

Transesophageal echocardiogram (TEE)

This test is generally ordered for patients with prosthetic valves if there is a question of the valves' function or to rule out stroke. In some patients with unexplained fevers, this test would be ordered to visualize the heart valves.

Excellence in cardiac catheterization

Door-to-balloon time is the amount of time lapsed from when a patient enters the hospital's doors to the re-establishment of blood flow to the heart using primary coronary intervention. The American Heart Association's recommended door-to-balloon time is 90 minutes or less. For patients experiencing a life-threatening type of heart attack called an ST-segment elevation myocardial infarction (STEMI), those precious minutes could literally mean the difference between life and death.

Fortunately for you and your loved ones, Liberty Hospital's Cardiac Catheterization Laboratory is one of the area's quickest at assessing and treating heart attack symptoms. Our two state-of-the-art cardiac cath labs are equipped with:

  • Flat-plane, high-resolution digital imaging systems
  • Interventional cardiologists experienced at performing radial artery angioplasty

Other advanced procedures

Our cardiology services department not only performs catheterizations and coronary interventions in the labs, but they also implant pacemakers and automatic implantable cardiac defibrillators. These patients are then followed in the hospital's pacemaker clinic.


Quality & Patient Satisfaction

Our patient satisfaction ratings consistently exceed national and local averages – and as the only Northland hospital to receive an "A" safety grade from The Leapfrog Group (Fall 2021 and Spring 2022), we are proud to be the highest-ranking hospital for safety in the Northland.
