Causes & Risk Factors
Several factors can contribute to Congestive Heart Failure with Preserved Ejection Fraction.
The underlying cause of heart failure with preserved ejection fraction involves changes in the heart muscle that make it stiff and less able to relax between heartbeats.
The underlying cause of heart failure with preserved ejection fraction involves changes in the heart muscle that make it stiff and less able to relax between heartbeats. Think of a healthy heart like a flexible balloon that easily expands to fill with air and contracts to push it out. In this condition, the heart muscle becomes more like a thick-walled tire that can still squeeze but has trouble expanding to let blood flow in. This stiffness forces pressures to rise inside the heart chambers, backing up into the lungs and body.
Several processes contribute to this muscle stiffening.
Several processes contribute to this muscle stiffening. Chronic high blood pressure forces the heart to work harder over years, causing the muscle walls to thicken and become less flexible. High blood sugar from diabetes damages tiny blood vessels in the heart muscle and promotes inflammation that leads to scarring. Age-related changes in proteins that give heart muscle its structure also play a role, which explains why this condition becomes more common as people get older.
Other factors that can trigger or worsen the condition include obesity, which increases the workload on the heart, kidney disease that affects fluid balance, and certain genetic variations that influence how heart muscle responds to stress over time.
Other factors that can trigger or worsen the condition include obesity, which increases the workload on the heart, kidney disease that affects fluid balance, and certain genetic variations that influence how heart muscle responds to stress over time. Sleep apnea, thyroid disorders, and some cancer treatments can also contribute to the development of this form of heart failure. Unlike heart attacks that cause sudden damage, this condition typically develops gradually over months or years as these various factors accumulate their effects on the heart muscle.
Risk Factors
- High blood pressure, especially if poorly controlled for years
- Type 2 diabetes or prediabetes
- Being overweight or obese, particularly abdominal weight
- Age over 65, with risk increasing each decade
- Being female, especially after menopause
- Family history of heart disease or heart failure
- Chronic kidney disease or reduced kidney function
- Sleep apnea or other breathing disorders during sleep
- Previous heart attack or coronary artery disease
- Sedentary lifestyle with little regular physical activity
Diagnosis
How healthcare professionals diagnose Congestive Heart Failure with Preserved Ejection Fraction:
- 1
Diagnosing heart failure with preserved ejection fraction requires careful detective work because the symptoms often overlap with other conditions, and standard tests may appear relatively normal.
Diagnosing heart failure with preserved ejection fraction requires careful detective work because the symptoms often overlap with other conditions, and standard tests may appear relatively normal. Doctors typically start with a thorough medical history and physical exam, listening for specific sounds in the lungs and heart that suggest fluid buildup or increased pressures. They'll check for swelling in the legs and feet, measure blood pressure, and assess how symptoms relate to daily activities.

The key diagnostic test is an echocardiogram, an ultrasound of the heart that measures how well the heart squeezes (ejection fraction) and, just as importantly, how well it relaxes and fills.
The key diagnostic test is an echocardiogram, an ultrasound of the heart that measures how well the heart squeezes (ejection fraction) and, just as importantly, how well it relaxes and fills. In this condition, the ejection fraction stays above 50 percent, but specific measurements of relaxation and filling pressures are abnormal. Blood tests help rule out other causes and may show elevated levels of substances like BNP or NT-proBNP, which the heart releases when under stress. Chest X-rays can reveal fluid in the lungs or an enlarged heart.

Sometimes doctors need additional tests to confirm the diagnosis or rule out other conditions.
Sometimes doctors need additional tests to confirm the diagnosis or rule out other conditions. These might include cardiac catheterization to directly measure pressures inside the heart chambers, stress tests to see how the heart responds to exercise, or advanced imaging with cardiac MRI. The challenge lies in distinguishing this condition from normal age-related changes in the heart, lung diseases that cause similar breathing problems, or other forms of heart disease that can mimic these symptoms.
Complications
- The primary complications of heart failure with preserved ejection fraction involve the progressive buildup of fluid in the lungs and body, which can lead to increasingly severe breathing problems and reduced quality of life.
- Pulmonary edema, where fluid accumulates in the lungs, can develop suddenly and requires immediate medical attention.
- This typically causes severe shortness of breath, anxiety, and sometimes a frothy cough.
- While treatable, repeated episodes can indicate worsening heart function and may require hospitalization for IV medications to remove excess fluid.
- Other complications can develop as the condition progresses or during periods of poor control.
- Kidney function may decline as reduced blood flow affects the kidneys' ability to filter waste and maintain proper fluid balance.
- Irregular heart rhythms, particularly atrial fibrillation, become more common and can worsen symptoms or increase stroke risk.
- Some people develop problems with other organs as reduced blood flow affects liver function or causes digestive issues.
- The good news is that with proper treatment and monitoring, many of these complications can be prevented or managed effectively, allowing people to maintain good quality of life for many years.
Prevention
- Preventing heart failure with preserved ejection fraction centers on controlling the risk factors that lead to heart muscle stiffening over time.
- The most powerful preventive step is maintaining healthy blood pressure throughout life, ideally keeping it below 130/80 mmHg through diet, exercise, stress management, and medication when needed.
- Regular blood pressure monitoring becomes increasingly important after age 50, as even mild elevations can gradually damage the heart muscle.
- Maintaining a healthy weight and staying physically active provide significant protection against developing this condition.
- Regular aerobic exercise, even moderate activities like brisk walking for 30 minutes most days, helps keep heart muscle flexible and improves overall cardiovascular health.
- Strength training twice weekly can also help maintain muscle mass and improve metabolism, reducing the risk of diabetes and obesity that contribute to heart muscle problems.
- Other preventive measures include managing diabetes carefully if diagnosed, avoiding smoking, limiting alcohol intake, and treating sleep apnea if present.
- Regular medical checkups allow early detection and treatment of conditions like high blood pressure or diabetes before they cause irreversible changes to heart muscle.
- While aging and genetic factors can't be changed, addressing modifiable risk factors can significantly reduce the likelihood of developing this form of heart failure or delay its onset by many years.
Treatment for heart failure with preserved ejection fraction focuses on managing symptoms and addressing the underlying conditions that contribute to heart muscle stiffness.
Treatment for heart failure with preserved ejection fraction focuses on managing symptoms and addressing the underlying conditions that contribute to heart muscle stiffness. Unlike other forms of heart failure, many traditional heart medications haven't shown clear benefits, so treatment often emphasizes controlling blood pressure, blood sugar, and fluid buildup. Diuretics, commonly called water pills, help reduce swelling and breathing problems by removing excess fluid from the body.
Blood pressure control stands as perhaps the most important treatment goal.
Blood pressure control stands as perhaps the most important treatment goal. ACE inhibitors, ARBs, or other blood pressure medications help reduce the workload on the heart and may slow progression of muscle stiffening. For people with diabetes, tight blood sugar control with appropriate medications helps prevent further damage to heart muscle. Some patients benefit from medications that slow the heart rate, giving more time for the heart to fill between beats.
Lifestyle changes form the foundation of treatment and often provide significant symptom relief.
Lifestyle changes form the foundation of treatment and often provide significant symptom relief. A structured exercise program, typically starting slowly and building gradually, can improve the heart's ability to relax and fill more effectively. Weight loss, even modest amounts, can reduce symptoms dramatically in overweight patients. Salt restriction helps prevent fluid retention, while limiting fluid intake may be necessary for some people during certain periods.
Newer treatments show promise for specific patients.
Newer treatments show promise for specific patients. SGLT2 inhibitors, originally diabetes medications, have shown benefits for some people with this condition even without diabetes. Research continues into medications that target the molecular changes causing muscle stiffness. For severe cases, some patients may benefit from devices that help optimize heart rhythm or, in rare cases, procedures to improve heart function.
Living With Congestive Heart Failure with Preserved Ejection Fraction
Living successfully with heart failure and preserved ejection fraction requires developing new daily routines that support heart health while maintaining an active, fulfilling life. Many people find that planning activities for times when energy levels are highest, typically mornings, helps them accomplish important tasks without overexertion. Breaking larger activities into smaller segments with rest periods can make previously challenging tasks manageable again. Monitoring daily weights helps detect early fluid retention before symptoms worsen, with increases of 2-3 pounds in a day or 5 pounds in a week warranting medical attention.
