Discovering New Strategies for Treating Advanced Heart Failure
By Jackie Ostrowicki
April 2021
Heart failure, which occurs when the heart is too weak to pump enough blood to meet the body's needs, , causes 55,000 deaths each year and indirectly contributes to 230,000 more deaths annually in the U.S. Although there have been recent improvements in congestive heart failure treatment, researchers say the prognosis for people with the disease is still bleak, with about 50% having an average .
Rebekah Gundry wants to use biomarkers and technology to identify and monitor progression of heart disease. A professor and vice chair of the Department of Cellular and Integrative Physiology at UNMC, Gundry is passionate about cardiovascular research. She is also the director of the CardiOmics program for the Center of Heart and Vascular Research at UNMC, which develops and applies advanced mass spectrometry technologies to improve clinical cardiovascular care.
Of the more than 6 million Americans living with heart failure, about . In short, that means conventional heart therapies and symptom management strategies are no longer working. Someone with advanced heart failure feels shortness of breath and other symptoms even at rest. Symptom severity can fluctuate, even within a single day. For those with advanced forms of heart failure, nearly .
However, having advanced heart failure doesn’t mean patients have run out of treatment options. In fact, the increasing number of therapies and state-of- the-art technologies for advanced heart failure provide more choices than ever. Gundry’s lab is part of that solution.
A Passion for Studying the Heart
The first time Gundry saw beating heart cells in the lab, it took her breath away.
Gundry was in her post-doctoral training at Johns Hopkins University and learning how to turn stem cells into heart cells. It's a moment she will never forget. A few years later, she had a similar moment when meeting a patient who had just received a heart pump and as a result, a reinvigorated outlook on life.
"You think of the organ conceptually, but to see the cells beating in front of you, and later to see the impact that technology can have on a person's quality of life, those are show-stopping moments," said Gundry.
Dr. Gundry's fascination with cardiovascular research grew out of her personal encounters with family members who suffered from heart disease, and an overall interest in the technological innovations that improve the lives of patients suffering from advanced heart failure.

A self-described techie, Dr. Gundry has focused her research on enhancing the use of stem cell-derived cardiomyocytes—the cells responsible for controlling the rhythmic beating of the heart—for accurate drug testing and disease modeling. Her goal? To discover new strategies for treating advanced heart failure.
Applying Technology to Medicine
Gundry’s research program develops and applies innovative mass spectrometry technologies to transform our understanding of how the heart works. Mass spectrometry measures the masses of molecules or groups of molecules. Because it is measuring at the molecular level, it delivers high-precision results. It’s used to better understand fundamental atomic and molecular processes, and their relevance to events within cells. As a technique, it helps diagnose diseases and discover new drugs, among other applications.
“Mass spectrometry is part of the technology that drives my lab; in fact, it’s at the center of our work,” Gundry said. “As we weigh the mass of molecules, it allows us to identify things, to characterize them, and to quantify them.” Her lab uses mass spectrometry to study surface proteins on both stem cells and heart cells.
She recently received a prestigious from the National Heart, Lung and Blood Institute that will fund her latest project. Gundry’s use of mass spectrometry focuses on the subset of molecules and proteins found on the surface of heart cells. These can be optimally exploited for drug targeting, and are critical players in normal cardiac function and disease.
For patients that need heart transplants and can’t get one, Gundry’s work may be able to help identify targeted drugs that would treat the heart and give it back more ability to beat. She may also be able to help clinicians determine which patients would benefit from implant devices.
“We would like to be able to shift more patients from the category that doesn't reach recovery to the category where they do reach recovery,” Gundry said. “My work is about helping clinicians make the right decision for the right patient. You might think of it as a personalized medicine type of approach that gets a particular patient the best treatment for their situation.”
Editors Note: Gundry is now a professor of and interim chair of the Department of Cellular and Integrative Physiology at UNMC.

Find Your Nebraska State Senator
Get started by entering your address below. Next, you'll receive information on who your senator is—and how to reach him or her.
Making a call only takes a few minutes and sends a strong message to your state senator. Your senator may not be able to take the call, but you can speak to the legislative aide who works for the senator. They will log your call, take a message and pass it on. Keep your conversation brief, and be sure to cover these essential points:
- Introduce yourself as a constituent in their district and provide your name.
- Be clear that you're calling about your support for the University of Nebraska System.
- Share your story about how the University has impacted you or your family. A personal story is hard to ignore. Explain why it's important to you that your senator invests in the University of Nebraska. Again, keep it brief and to-the-point.
- Ask for your opinion to be noted. Politely finish the call by thanking the senator or legislative aide for their time.
Send an Email
Sending a written message to your state senator is an easy way to engage your representative. They're more concise and easier to respond to, and they're more likely to be viewed by the senator. If you can, send a personalized message with these essential points. Keep your message brief (a paragraph or so).
- Write a personal, attention-getting subject line that lets the senator know your topic— "Investing in the University of Nebraska System" or "Supporting the University of Nebraska System"
- Introduce yourself as a constituent in their district; provide your name.
- Be clear that you're writing about your support for the University of Nebraska System
- Share your personal story about how the University has impacted you or your family. Explain why it's important to you that your senator invests in the University of Nebraska. Again, keep it brief and to-the-point.
- Ask if your senator will support the University moving forward.
- Indicate that you'd appreciate a reply and thank your senator for their time.
