A cardiovascular exercise scientist at the University of Texas at Arlington’s College of Nursing and Health Innovation has received a $308,000 grant from the National Institutes of Health to study exercise intolerance in older heart failure patients with preserved ejection fraction, or HFpEF. 

Mark Haykowsky, a professor of nursing and the college’s Moritz Chair of Gerontological Nursing Research, and a team of researchers from the college will study the mechanisms and management of exercise intolerance and its improvement with endurance exercise training in older HFpEF patients. 

Preserved ejection fraction is the fastest growing type of heart failure and is found mostly in older individuals. The mortality rate for these patients is high and the cardinal feature among them is impaired exercise tolerance. While evidence based drug therapies improve survival in heart failure patients with reduced ejection fraction, they do not improve survival in HFpEF patients, Haykowsky said.

“We are looking at peripheral non-cardiac factors that affect exercise tolerance and their improvement with exercise training,” he said. “In HFpEF patients, we believe that the muscle sympathetic activity is over active. We will also be measuring HFpEF patients’ cardiorespiratory fitness, aerobic endurance, functional performance and quality of life.”

Haykowsky will work with several leading heart disease researchers from the college on this study, including Paul Fadel, a professor, neural cardio-vascular control expert and the college’s associate dean for research; Michael Nelson, an assistant professor of kinesiology, who is studying a frequently misdiagnosed heart condition in women; and Kathryn Daniel and Daisha Cipher, both associate professors in the college. 

They will study HFpEF patients and healthy controls who are 60 and older. The HFpEF patients will then be randomly assigned to two exercise training groups. One group will meet at UTA for exercise sessions three days a week for 16 weeks. The second group will be a control group. Researchers will strive to improve the muscle sympathetic nerve activity, cardiorespiratory fitness, aerobic endurance and functional performance and quality of life.   

“This grant is a huge win for our research faculty, for the college and for the University of Texas at Arlington,” said Anne Bavier, dean of the College of Nursing and Health Innovation. “The study conducted by Professor Haykowsky and his team of seasoned researchers will make a significant contribution to the body of knowledge on heart disease and help us get to the bottom of some heart ailments that continue to elude us.”
