Maintaining a normal ejection fraction is essential for heart health, but when the heart’s pumping ability is preserved at healthy levels, treatment focuses on preventing complications and managing underlying conditions that could threaten cardiac function.

Understanding Heart Function and Treatment Goals

When your heart maintains a normal ejection fraction, it means the lower left chamber of your heart is pumping blood effectively with each beat. In healthy hearts, this measurement typically falls between 50% and 70%, meaning that more than half of the blood filling the heart’s main pumping chamber gets pushed out to the body with each contraction.^[1] This percentage is a fundamental indicator of how well your heart performs its vital job of delivering oxygen-rich blood to all your organs and tissues.

However, having a normal ejection fraction does not automatically mean your heart is completely healthy or free from problems. Some people experience a condition called heart failure with preserved ejection fraction, or HFpEF, where the pumping percentage remains in the normal range, but other heart problems cause symptoms and complications.^[1] This happens when the heart muscle becomes thick or stiff, which limits how much blood the ventricle can hold between beats. Even though the heart pumps out a normal percentage of the blood it contains, the total amount delivered to the body is insufficient because the chamber holds less blood to begin with.

Treatment approaches for maintaining normal ejection fraction or managing HFpEF differ significantly from treatments for reduced ejection fraction. The goals center on controlling underlying conditions that stress the heart, preventing the development of more severe heart problems, and managing symptoms when they occur. Medical professionals focus on identifying and treating the root causes that could eventually damage the heart muscle and reduce its pumping ability over time.

Standard Treatment Approaches

When ejection fraction remains normal but heart problems exist or risk factors are present, doctors implement several treatment strategies. The primary focus involves managing conditions that commonly lead to heart failure with preserved ejection fraction. High blood pressure stands as one of the most significant risk factors, and controlling it becomes a top priority in treatment plans.^[10]

For managing high blood pressure in people with preserved ejection fraction, healthcare providers often prescribe calcium channel blockers. These medications work by relaxing the blood vessels and reducing the force needed for the heart to pump blood. By lowering blood pressure, calcium channel blockers decrease the strain on the heart muscle and may help prevent it from becoming thick or stiff over time.^[10] These drugs are particularly valuable because they address both blood pressure control and help maintain the heart’s ability to relax between beats.

Medications that affect the renin-angiotensin-aldosterone system play another crucial role in treatment. This group includes angiotensin-converting enzyme inhibitors (ACE inhibitors), angiotensin receptor blockers (ARBs), and aldosterone antagonists. ACE inhibitors work by blocking the production of a hormone that narrows blood vessels, which helps blood vessels relax and lowers blood pressure. ARBs produce similar effects by blocking the action of the same hormone at a different point in the process.^[10] These medications not only control blood pressure but may also help reduce the thickness of the heart muscle in people with high blood pressure, potentially preventing progression to more severe heart problems.

Aldosterone antagonists represent another important medication class, especially for people with heart failure and preserved ejection fraction. These drugs block the effects of aldosterone, a hormone that causes the body to retain salt and water, which increases blood volume and blood pressure. By counteracting aldosterone, these medications help reduce fluid buildup and decrease the workload on the heart.

Diuretics, commonly called water pills, are frequently prescribed to manage symptoms related to fluid retention. When the heart cannot pump efficiently enough, fluid can accumulate in the lungs, legs, and other parts of the body, causing shortness of breath and swelling. Diuretics help the kidneys remove excess salt and water through urine, which reduces the volume of blood the heart needs to pump and relieves pressure in the blood vessels.^[10] This makes breathing easier and reduces swelling in the legs and ankles.

For people with heart disease caused by blocked arteries, treatment often includes antiplatelet therapy and anticoagulants. Antiplatelet drugs, such as aspirin, help prevent blood clots from forming in narrowed arteries, reducing the risk of heart attacks. Anticoagulants work similarly but through a different mechanism. These medications are particularly important for people who have had heart attacks or have coronary artery disease, as they help maintain blood flow to the heart muscle.^[10]

Beta blockers serve multiple purposes in heart treatment. They slow the heart rate and reduce the force of heart contractions, which decreases the heart’s oxygen demand. Beta blockers are particularly useful for treating ischemic heart disease, where the heart muscle doesn’t receive enough oxygen due to narrowed arteries. They also help control irregular heart rhythms and can improve symptoms in people with heart failure.^[10] For people with atrial fibrillation, an irregular heart rhythm that commonly occurs with heart failure, beta blockers help keep the heart rate under control.

Digoxin is another medication used to control heart rate, especially in people with atrial fibrillation. This drug increases the force of heart contractions while slowing the heart rate, which can improve symptoms and help the heart pump more effectively. Digoxin has been used for many years and remains useful for specific situations, particularly when other medications don’t adequately control heart rate.^[10]

The duration of treatment typically extends for life, as the underlying conditions that affect heart function are usually chronic. Medications need to be taken regularly and as prescribed to maintain their protective effects. Healthcare providers monitor patients regularly to assess how well medications are working and to watch for any side effects.

Side effects vary depending on the specific medications. Diuretics may cause increased urination, which can be inconvenient, and may lead to electrolyte imbalances that require monitoring through blood tests. ACE inhibitors sometimes cause a persistent dry cough, and some people develop a mild rash. ARBs generally have fewer side effects but can cause dizziness in some people. Beta blockers may cause fatigue, cold hands and feet, or difficulty sleeping in certain individuals. Calcium channel blockers can cause ankle swelling, constipation, or dizziness.

Regular follow-up appointments with healthcare providers are essential for people maintaining normal ejection fraction with treatment. These visits typically occur at least every six months and involve discussions about symptoms, medication adjustments if needed, and tests to monitor heart function and overall health.^[19] Blood tests check kidney function, electrolyte levels, and other indicators that medications might affect.

Treatment Being Studied in Clinical Trials

Research into heart failure with preserved ejection fraction continues actively, as scientists work to understand this condition better and develop more effective treatments. Unlike heart failure with reduced ejection fraction, where many proven therapies exist, HFpEF has been more challenging to treat, and researchers are investigating new approaches.

Clinical trials explore various strategies to improve outcomes for people with heart failure and preserved ejection fraction. Many of these studies focus on understanding the underlying mechanisms that cause the heart muscle to become stiff and the ventricle to hold less blood. Researchers investigate how inflammation, changes in the way heart cells process energy, and alterations in the proteins that give heart muscle its structure contribute to this condition.

Some clinical trials examine whether medications already approved for other conditions might benefit people with preserved ejection fraction heart failure. These studies test different combinations of existing drugs to see if using them together produces better results than using them individually. Researchers also investigate optimal dosing strategies and try to identify which patients are most likely to benefit from specific treatments.

Studies conducted in various locations, including the United States and Europe, enroll patients who meet specific criteria related to their heart function, symptoms, and overall health status. Eligibility for these trials typically requires documented evidence of heart failure symptoms, a normal or near-normal ejection fraction confirmed through imaging tests, and the absence of certain other medical conditions that might interfere with study results.

Phase I clinical trials in this area focus on safety, testing new approaches in small groups of people to determine if they cause unacceptable side effects. Phase II trials involve larger groups and begin to assess whether the treatment shows promise for improving symptoms or heart function measures. Phase III trials compare new treatments directly against current standard treatments in large groups of patients to determine if the new approach offers clear advantages.

Some research investigates medications that target specific molecular pathways involved in heart muscle stiffness and dysfunction. These experimental drugs aim to improve how the heart muscle relaxes between beats or to prevent the progressive thickening and stiffening that characterizes heart failure with preserved ejection fraction. Early results from some of these studies have shown improvements in exercise capacity, reductions in hospitalizations, or better quality of life scores, though more research is needed to confirm these benefits.

Other clinical trials explore whether intensive management of risk factors, such as blood pressure, blood sugar in people with diabetes, and cholesterol levels, can prevent the development of heart failure in people who currently have normal ejection fraction but are at high risk. These prevention studies are particularly important because stopping heart disease before it causes symptoms is always preferable to treating it after problems develop.

Exercise-based interventions represent another area of active research. Clinical trials examine whether structured exercise programs can improve heart function, increase exercise capacity, and enhance quality of life in people with preserved ejection fraction heart failure. These studies test different types of exercise, including aerobic activity and resistance training, and investigate optimal intensity and duration of physical activity programs.

Researchers also study whether treating specific underlying conditions that commonly occur alongside heart failure with preserved ejection fraction can improve outcomes. For example, many people with this condition also have obesity, sleep apnea, or kidney disease. Clinical trials investigate whether addressing these related conditions more aggressively can help the heart function better and reduce symptoms.

The ultimate goal of all this research is to develop more effective treatments that can reduce symptoms, improve quality of life, decrease hospitalizations, and extend survival for people with heart failure and preserved ejection fraction. As researchers learn more about the complex mechanisms underlying this condition, they hope to identify new therapeutic targets and develop innovative treatments tailored to the specific problems these patients face.

Lifestyle Changes and Self-Management

Beyond medications, lifestyle modifications play a crucial role in maintaining heart health when ejection fraction is normal. Regular physical activity represents one of the most effective strategies for supporting heart function and improving overall health. Exercise-based cardiac rehabilitation programs are often recommended, where healthcare professionals guide people through structured exercise routines tailored to their specific abilities and needs.^[19]

These rehabilitation programs typically include education about heart-healthy living, instruction on proper exercise techniques, and emotional support. Before starting any exercise program, people undergo assessments to determine safe activity levels. The exercise component can then be customized to match individual capabilities, ensuring safety while providing maximum benefit. Regular physical activity helps the body use oxygen more efficiently, which can compensate for any limitations in heart function and improve symptoms like fatigue and shortness of breath.

Maintaining a healthy, balanced diet supports heart health and helps manage conditions that stress the heart. Healthcare providers often recommend eating plenty of fruits and vegetables, choosing whole grains, including lean proteins, and limiting saturated fats, salt, and sugar.^[19] For some people, restricting fluid intake may be necessary to prevent excessive fluid accumulation, though this recommendation varies based on individual circumstances and should be discussed with a healthcare provider.

Weight management becomes important for people who are overweight, as excess body weight increases the heart’s workload. Losing even modest amounts of weight can significantly reduce blood pressure and decrease strain on the heart. Healthcare providers can offer guidance on safe, effective weight loss strategies that fit individual lifestyles and health conditions.

Smoking cessation is critical for anyone with heart concerns. Smoking damages blood vessels, raises blood pressure, and reduces the amount of oxygen in the blood, all of which harm the heart. Healthcare providers can provide support for quitting, including counseling and medications that help manage withdrawal symptoms and cravings.^[19]

Alcohol consumption should be limited or avoided entirely in some cases. While moderate alcohol intake may be acceptable for some people with heart conditions, excessive drinking can weaken the heart muscle and worsen heart failure. People whose heart problems are directly related to alcohol consumption may be advised to stop drinking completely.^[19]

Vaccination against influenza and pneumococcal disease is recommended for people with heart conditions. Heart problems can make the body more vulnerable to infections, which can put additional stress on an already compromised cardiovascular system. Annual flu vaccines and one-time pneumococcal vaccination provide important protection.^[19]

Self-monitoring between medical appointments helps detect problems early. Some people are asked to weigh themselves regularly, as sudden weight gain can indicate fluid retention and worsening heart function. Keeping track of symptoms and reporting any changes to healthcare providers enables quick intervention when needed. Understanding when and where to seek medical advice for concerning symptoms is an important part of self-management.

Travel is usually possible for people with well-controlled heart conditions and normal ejection fraction, though some precautions may be necessary. High altitudes and hot, humid environments can put extra strain on the heart, so these may need to be avoided. Air travel is generally safe, though people with severe symptoms should consult their healthcare provider before flying. Taking adequate medication supplies and carrying prescriptions when traveling helps ensure continuous treatment.^[19]

Managing stress and emotional health is equally important as physical health. Living with a heart condition can cause anxiety, fear, or depression. These emotional challenges deserve attention and treatment. Healthcare providers can recommend counseling, support groups, or other resources to help people cope with the psychological aspects of living with heart disease. Relaxation techniques, adequate sleep, and maintaining social connections all contribute to emotional well-being and overall health.

Many people with well-controlled heart conditions can continue working and enjoying their usual activities. The key is finding the right balance between staying active and not overexerting. Healthcare providers can offer guidance on returning to work safely and suggest modifications if certain job activities put too much strain on the heart. With proper treatment and lifestyle management, most people with normal ejection fraction can maintain good quality of life and continue participating in activities they enjoy.
