The ABCs of Heart Tests

CTs, MRIs, EKGs, ECGs and More

ABCs blogMRI? CT? ECG? What are all these tests and what does it all mean? Here’s a guide to the many different heart tests your doctor may order and what they’re designed to do.

Magnetic resonance imaging (MRI)

A noninvasive test that uses a magnetic field and radiofrequency waves to create detailed pictures of organs and structures inside your body. It can be used to examine your heart and blood vessels, and to identify areas of the brain affected by stroke. MRI is also sometimes called nuclear magnetic resonance (NMR) imaging.

Reasons for the test:

  • Assess heart structure
  • Determine the health of the heart valves

CT scan

An X-ray imaging technique that uses a computer to produce cross-sectional images. Also referred to as cardiac computed tomography, computerized axial tomography or CAT scan, it can be used to examine the heart and blood vessels for problems. It is also used to identify the blood vessels in the brain affected by stroke.

Reasons for the test:

  • To assess the structure of the heart
  • To determine if blockages are present

Echocardiogram

Uses sound waves to produce images of your heart. This common test allows your doctor to see how your heart is beating and pumping blood. Your doctor can use the images from an echocardiogram to identify various abnormalities in the heart muscle and valves.

Reasons for the test:

  • Determine the cause of a heart murmur
  • Track heart valve disease
  • Assess the overall function of the heart

Blueberries and heart health

blueberrie blogFall is the season for pumpkins, apples and … blueberries? While summer is long gone, there are plenty of reasons to keep these heart-healthy berries on the fall menu. In fact, blueberries and heart health go hand in hand.

Color me healthy

Blueberries contain high amounts of brightly colored pigments called anthocyanins, which deliver a number of benefits for heart health. While other berries such as strawberries and cranberries contain anthocyanins as well, blueberries contain an especially high amount. These powerhouse pigments may help to reduce blood pressure, lower “bad” cholesterol and keep arteries healthy. Eating berries has even been shown to decrease the risk of death from heart disease.


Lose the (oxidative) stress

Cell damage from oxidative stress can lead to a number of conditions, such as Alzheimer’s, cancer and heart disease. Anthocyanins function as strong antioxidants; they can protect against damage to cells and DNA. The antioxidant compounds found in blueberries lower inflammation and decrease oxidative stress — both of which help to protect heart health.

The whole package

Why not just pop a pill to get your daily dose of anthocyanins? Well, blueberries offer a number of benefits apart from that one compound. They are low in calories, high in fiber and rich in a number of vitamins and minerals. Plus, different components found in blueberries may work in concert to help the body absorb and utilize all of the berry’s heart-healthy components.

Recipe:

Blueberry Apple Walnut Crisp

Even though it may be hard to find fresh blueberries now, frozen berries work well for baking and cooking — and are just as healthy as fresh! Reap the benefits of berries with this heart-healthy recipe:

Atrial fibrillation triggers

Afib can be difficult to diagnose because of varying symptoms

99146355 450x320Atrial fibrillation, also known as Afib, is an irregular heart rhythm (arrhythmia) that starts in the atria, or the upper chambers of the heart. According to the American Heart Association, an estimated 2.7 million Americans are living with Afib.

Although many atrial fibrillation triggers are common, each person’s experience is unique. So, being aware of your condition, along with your ability to identify the triggers that can potentially cause an episode, are important in helping you control atrial fibrillation symptoms, which may include:

  • Fluttering, racing or pounding of the heart

TAVR patient gets back to enjoying life

Marilyn Reeve TAVR 320x320

TAVR patient Marilyn Reeve

Marilyn Reeve’s heart issues started with quadruple bypass surgery at age 59. Ten years later, she began having trouble walking short distances, needing to stop often to catch her breath. The diagnosis was aortic valve stenosis. Due to her health history, open-heart surgery was out of the question, according to her doctor. “She recommended I go to the University of Michigan to see if there was anything they could do for me,” Marilyn says.

Fortunately, Marilyn was a candidate for Transcatheter Aortic Valve Replacement (TAVR), a procedure for those who cannot tolerate open-heart surgery. Marilyn’s TAVR procedure was a success. “I had my procedure on a Friday and was home on Monday. It’s marvelous what they can do,” she says.

Today, at age 70, Marilyn is back to doing all her own yard work as well as other physical things she couldn’t have done two years ago. She credits the entire U-M TAVR team with helping her get her health back. “U-M is the best hospital ever,” she says. Continue reading
