When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Chronic Heart Failure with Preserved Ejection Fraction.
The root cause of HFpEF lies in the heart muscle becoming stiff and less flexible over time.
The root cause of HFpEF lies in the heart muscle becoming stiff and less flexible over time. This stiffness prevents the left ventricle from filling properly with blood between heartbeats. While the heart can still squeeze and pump blood out normally, it struggles to relax and expand to receive the next round of blood from the lungs and body.
Several conditions contribute to this stiffening process.
Several conditions contribute to this stiffening process. High blood pressure tops the list, as years of forcing the heart to pump against elevated pressure causes the muscle walls to thicken and become rigid. Diabetes accelerates this process through multiple mechanisms, including inflammation and changes in how heart muscle cells handle energy. Aging naturally reduces heart muscle flexibility, which explains why HFpEF becomes more common in older adults.
Other factors that promote heart stiffness include obesity, which increases the heart's workload and triggers inflammatory processes.
Other factors that promote heart stiffness include obesity, which increases the heart's workload and triggers inflammatory processes. Kidney disease creates a cascade of problems including fluid retention and blood pressure changes. Sleep apnea repeatedly stresses the heart through oxygen fluctuations. Some people also have genetic predispositions that make their heart muscle more likely to become stiff over time.
Risk Factors
- Age over 65 years
- High blood pressure, especially long-standing
- Type 2 diabetes or prediabetes
- Obesity, particularly abdominal weight
- Female gender, especially after menopause
- Family history of heart disease
- Chronic kidney disease
- Sleep apnea or sleep disorders
- History of heart attack or coronary artery disease
- Sedentary lifestyle with little physical activity
Diagnosis
How healthcare professionals diagnose Chronic Heart Failure with Preserved Ejection Fraction:
- 1
Diagnosing HFpEF requires detective work since symptoms overlap with many other conditions.
Diagnosing HFpEF requires detective work since symptoms overlap with many other conditions. Your doctor will start with a detailed history about your symptoms, when they occur, and what makes them better or worse. They'll examine you for signs of fluid retention like swollen ankles or neck vein distension, and listen to your heart and lungs for abnormal sounds.

The key diagnostic test is an echocardiogram, which uses ultrasound to create moving pictures of your heart.
The key diagnostic test is an echocardiogram, which uses ultrasound to create moving pictures of your heart. This test measures ejection fraction - the percentage of blood pumped out with each heartbeat. In HFpEF, this number appears normal (usually above 50%), but other measurements reveal problems with how the heart fills and relaxes. Your doctor will also likely order blood tests including BNP or NT-proBNP, substances that rise when the heart is under stress.

Additional tests help rule out other causes of your symptoms and assess the severity of the condition.
Additional tests help rule out other causes of your symptoms and assess the severity of the condition. These might include: - Chest X-ray to check for fluid in the lungs - Electrocardiogram (EKG) to examine heart rhythm - Stress testing to see how your heart performs during activity - Cardiac catheterization in some cases to measure pressures directly - Blood tests to check kidney function, thyroid levels, and diabetes markers
Complications
- HFpEF can lead to several serious complications, though many can be prevented or managed with proper treatment.
- The most immediate concerns involve episodes of acute heart failure, where fluid backs up into the lungs causing severe shortness of breath that may require hospitalization.
- These episodes often occur when the condition worsens due to infections, medication non-compliance, or dietary indiscretions.
- Long-term complications may include irregular heart rhythms, particularly atrial fibrillation, which occurs in about 40% of HFpEF patients.
- Kidney function may decline over time due to reduced blood flow.
- Some patients develop pulmonary hypertension, where blood pressure in the lungs becomes elevated.
- The good news is that with proper management, many people with HFpEF maintain good quality of life and avoid these complications for many years.
Prevention
- Maintaining a healthy weight through balanced nutrition and regular activity
- Managing diabetes aggressively if you have it, keeping blood sugars in target ranges
- Staying physically active with at least 150 minutes of moderate exercise weekly
- Limiting sodium intake and following a heart-healthy diet rich in fruits and vegetables
- Getting adequate sleep and treating sleep apnea if present
- Not smoking or quitting if you currently smoke
Treating HFpEF focuses heavily on managing underlying conditions and relieving symptoms, since no medications have been proven to significantly improve survival specifically for this condition.
Treating HFpEF focuses heavily on managing underlying conditions and relieving symptoms, since no medications have been proven to significantly improve survival specifically for this condition. The foundation of treatment involves controlling blood pressure, managing diabetes, and addressing other contributing factors that make the heart stiffer.
Medications play several important roles.
Medications play several important roles. Diuretics help remove excess fluid that causes swelling and breathing difficulties. ACE inhibitors or ARBs may help with blood pressure control and potentially reduce heart stiffness. Beta-blockers can slow the heart rate, giving it more time to fill between beats. Some patients benefit from medications that specifically target diabetes, kidney disease, or sleep disorders.
Lifestyle modifications often provide the most dramatic improvements in how patients feel day-to-day.
Lifestyle modifications often provide the most dramatic improvements in how patients feel day-to-day. Regular, moderate exercise helps improve the heart's ability to relax and fill, though the exercise program should be tailored to your current fitness level. Weight management reduces the heart's workload and decreases inflammation. Limiting sodium intake to less than 2,300 mg daily helps prevent fluid retention.
Emerging treatments show promise for the future.
Emerging treatments show promise for the future. Newer diabetes medications called SGLT2 inhibitors have shown benefits in heart failure patients even without diabetes. Researchers are studying medications that specifically target heart muscle stiffness. Some patients may benefit from devices that help manage fluid levels or improve heart function, though these remain under investigation for HFpEF specifically.
Living With Chronic Heart Failure with Preserved Ejection Fraction
Living well with HFpEF requires becoming an active partner in your healthcare and making thoughtful adjustments to your daily routine. Most people find that spreading activities throughout the day, rather than trying to do everything at once, helps manage fatigue and shortness of breath. Planning rest periods and listening to your body's signals becomes essential for maintaining energy levels.
