Diastolic Heart Failure: Causes, Symptoms and Diagnosis
Heart failure is a condition that affects millions of people worldwide. Among the various types of heart failure, diastolic heart failure is often misunderstood. In this article, we will delve into the symptoms, causes, diagnosis, and treatment of diastolic heart failure to help you gain a better understanding of this condition.

Get A Second OpinionWhat is Diastolic Heart Failure?
Diastolic heart failure, also known as heart failure with preserved ejection fraction (HFpEF), occurs when the heart's lower chambers (ventricles) become stiff and cannot relax properly. This stiffness prevents the ventricles from filling up with enough blood, leading to a reduction in the amount of blood pumped out to the body.
Symptoms of Diastolic Heart Failure
Diastolic heart failure can manifest through various symptoms, which may be mild at first but can worsen over time. Common symptoms include:
- Shortness of Breath: Difficulty breathing, especially during physical activity or when lying down.
- Fatigue: Persistent tiredness and a lack of energy.
- Swelling: Swelling in the legs, ankles, feet, or abdomen due to fluid buildup.
- Rapid Heartbeat: An unusually fast or irregular heartbeat.
- Difficulty Exercising: Reduced ability to perform physical activities.
Causes of Diastolic Heart Failure
Several factors can contribute to the development of diastolic heart failure, including:
- High Blood Pressure: Chronic high blood pressure can lead to the stiffening of the heart muscles.
- Aging: The risk of diastolic heart failure increases with age.
- Obesity: Excess weight puts additional strain on the heart.
- Diabetes: Diabetes can damage the heart and blood vessels.
- Coronary Artery Disease: Blockages in the coronary arteries can reduce blood flow to the heart muscle.
- Atrial Fibrillation: An irregular heartbeat can cause the heart to work harder, leading to stiffness.
Systolic vs. Diastolic Heart Failure
It's important to distinguish between systolic and diastolic heart failure. While both conditions involve heart failure, they have different underlying mechanisms:
- Systolic Heart Failure: This occurs when the heart's ventricles cannot contract effectively, leading to a reduced ejection fraction (the percentage of blood leaving the heart each time it contracts).
- Diastolic Heart Failure: In this condition, the heart's ventricles are stiff and cannot relax properly, but the ejection fraction is usually preserved.
Diagnosing Diastolic Heart Failure
Diagnosing diastolic heart failure involves several steps:
Medical History and Physical Examination
Your doctor will start by reviewing your medical history and performing a physical examination. They will look for signs of heart failure, such as swelling in the legs and abdomen, and listen for abnormal heart sounds.
Diagnostic Tests
To confirm the diagnosis, your doctor may order one or more of the following tests:
- Echocardiogram: This ultrasound test provides images of the heart's structure and function, helping to identify stiffness and abnormal relaxation of the ventricles.
- Electrocardiogram (ECG): This test records the electrical activity of the heart and can detect irregularities in the heartbeat.
- Chest X-ray: An X-ray can reveal an enlarged heart or fluid buildup in the lungs.
- Blood Tests: Blood tests can help identify underlying conditions, such as diabetes or kidney problems, that may contribute to heart failure.
Chronic Diastolic Heart Failure
Chronic diastolic heart failure is a long-term condition that requires ongoing management. It is essential to work closely with your healthcare provider to develop a treatment plan that addresses your specific needs.
Treatment Options for Diastolic Heart Failure
While there is no cure for diastolic heart failure, various treatments can help manage the symptoms and improve your quality of life. Treatment options include:
Medications
Several medications can help manage diastolic heart failure, including:
- Diuretics: These medications help reduce fluid buildup in the body by increasing urine production.
- Beta-Blockers: Beta-blockers can slow the heart rate and reduce blood pressure, easing the workload on the heart.
- ACE Inhibitors and ARBs: These medications help relax blood vessels and lower blood pressure, improving blood flow.
- Calcium Channel Blockers: These drugs can help relax the heart muscles and improve blood flow.
Lifestyle Changes
Making certain lifestyle changes can significantly impact your heart health:
- Diet: Adopt a heart-healthy diet that includes plenty of fruits, vegetables, whole grains, and lean proteins. Limit salt, saturated fats, and cholesterol.
- Exercise: Engage in regular physical activity, such as walking, swimming, or cycling, to improve cardiovascular health. Consult your doctor before starting a new exercise routine.
- Weight Management: Maintain a healthy weight to reduce strain on your heart.
- Quit Smoking: If you smoke, seek help to quit, as smoking can worsen heart failure.
- Limit Alcohol: Reduce alcohol consumption to minimize its impact on your heart.
Monitoring and Follow-Up
Regular monitoring and follow-up appointments with your healthcare provider are crucial for managing diastolic heart failure. Your doctor may adjust your treatment plan based on your progress and any changes in your condition.

Book an AppointmentPreventing Diastolic Heart Failure
While some risk factors for diastolic heart failure, such as age and genetics, cannot be controlled, there are steps you can take to reduce your risk:
- Manage Blood Pressure: Keep your blood pressure under control through medication, diet, and exercise.
- Control Diabetes: If you have diabetes, work with your healthcare provider to manage your blood sugar levels.
- Maintain a Healthy Weight: Aim for a healthy weight to reduce the strain on your heart.
- Stay Active: Engage in regular physical activity to keep your heart healthy.
- Eat a Heart-Healthy Diet: Choose foods that support heart health and avoid those that can contribute to heart disease.
Frequently Asked Questions
1. What is diastolic heart failure?
Diastolic heart failure occurs when the heart’s ventricles become stiff and do not fill properly with blood, leading to fluid buildup.
2. What are the symptoms of diastolic heart failure?
Symptoms include shortness of breath, fatigue, and swelling in the legs and ankles, often worsening during physical activity.
3. What causes diastolic heart failure?
Causes include hypertension, aging, obesity, and conditions like diabetes that affect the heart’s ability to relax.
4. How is diastolic heart failure treated?
Treatment includes managing blood pressure, reducing fluid retention with diuretics, and lifestyle changes like diet and exercise.
5. How is diastolic heart failure diagnosed?
Diagnosis involves echocardiograms, blood tests, and sometimes MRI to assess heart function and the extent of stiffness in the ventricles.
