Heart failure is one of the biggest health challenges facing the United States and many other countries. Millions of people live with this condition, and the number continues to rise as the population gets older.
Heart failure can lead to repeated hospital stays, a lower quality of life, and very high healthcare costs. It develops when the heart cannot supply enough blood and oxygen to meet the body’s needs.
Many people with heart failure experience symptoms that make everyday activities difficult. They may become short of breath after walking short distances, feel tired most of the time, or develop swelling in their legs, ankles, and feet because fluid builds up in the body.
These symptoms can make simple tasks, such as climbing stairs or shopping for groceries, much harder.
Most people imagine heart failure as a condition in which the heart becomes weak and loses its ability to pump blood properly. However, there is another form of heart failure that is just as common.
In this type, the heart can still squeeze normally, but it becomes stiff and cannot relax enough to fill with blood between heartbeats. Doctors call this condition heart failure with preserved ejection fraction, or HFpEF. It is sometimes simply called “stiff heart” heart failure.
Treating HFpEF has been a major challenge for doctors because there are still very few proven treatments. As a result, physicians often prescribe medicines that work well in other forms of heart failure, hoping they may also help people with stiff heart failure.
One of the most commonly prescribed drugs is a group of medicines called beta-blockers. These medications slow the heart rate and reduce the effects of stress hormones on the heart.
They are often used to lower blood pressure, control abnormal heart rhythms, and reduce the chances of future heart attacks. Beta-blockers are known to save lives in people whose hearts have become weak and cannot pump efficiently.
However, new research suggests that the story may be very different for people with stiff heart failure.
Researchers at the University of Vermont reviewed information from a large clinical study known as the TOPCAT trial, which included people with HFpEF. Around 80 percent of the participants were taking beta-blockers.
When the researchers looked at the outcomes, they found something concerning. People taking beta-blockers were 74 percent more likely to be hospitalized because of heart failure.
The findings suggest that these medicines may not simply be ineffective in people with stiff heart failure. In some cases, they may actually make symptoms worse.
Since the stiff heart already struggles to relax and fill with blood, beta-blockers may increase pressure inside the heart. This can lead to more fluid buildup in the lungs and body, making it harder for people to breathe and increasing swelling.
The study also highlights an important lesson in medicine. A treatment that works very well for one disease may not work for another condition that looks similar. Although both forms of heart failure share the same name, they affect the heart in different ways. Therefore, they may require different treatment approaches.
For patients and their families, these findings are a reminder that medications should never be viewed as one-size-fits-all solutions. People with stiff heart failure should speak with their healthcare providers about the reasons for taking each medicine and ask whether there is strong evidence supporting its use in their particular condition.
The researchers, led by Dr. Timothy Plante, hope that these findings will encourage more studies focused on better treatments for HFpEF. At present, people living with stiff heart failure still have limited treatment options, and there is an urgent need for therapies that can safely improve symptoms and reduce hospital visits.
The study was published in JAMA Network Open. The findings point toward a future in which heart failure treatment becomes more personalized, with doctors choosing therapies based on the specific type of heart failure each person has rather than assuming that one treatment works equally well for everyone.
