Diagnosing Diastolic Heart Failure

Overview

Diastolic heart failure refers to a condition where the left ventricle of the heart has difficulty relaxing during the diastole phase, which is the period between heartbeats. Specialists who may be involved in the diagnosis of diastolic heart failure include cardiologists and other healthcare professionals. To diagnose diastolic heart failure, doctors may perform several examinations, screening tests, and procedures. These tests include:

• Physical exam: During a physical exam, doctors will take note of any symptoms that might be present and ask about medications and other health conditions.
• Blood tests: Blood tests can provide valuable information about heart strain and can help diagnose strain on the liver and kidneys, which can develop due to heart failure. Some specific blood tests that may be ordered include:
  • Basic metabolic panel
  • Complete blood count
  • Iron studies
  • B-type natriuretic peptide (BNP) test
  • Lipid profile
  • Thyroid function tests
• Echocardiogram: An echocardiogram is a type of ultrasound that uses sound waves to create detailed images of the heart's structure and function. It can help measure a person's ejection fraction (a measure of how well the heart pumps blood) and provide information about the heart's pumping capacity.
• MRI: Magnetic resonance imaging (MRI) reveals the structure of the heart and can indicate whether there is a lack of blood supply traveling to the heart or damage from a previous heart attack.
• Chest X-ray: A chest X-ray can help identify heart enlargement or fluid accumulation in the lungs, which are common signs of heart failure.
• Electrocardiogram (ECG or EKG): This test records the electrical activity of the heart using electrodes attached to the skin. It can detect abnormal heart rhythms and provide information about any congestion or abnormalities in the heart.
• Stress test: Also known as a treadmill test, a stress test monitors the heart's activity during exercise. It helps determine the type of exercise suitable for the body and can provide insights into how the heart responds to stress.

These examinations, screening tests, and procedures help doctors confirm a diagnosis of diastolic heart failure by assessing the function and structure of the heart, measuring biomarkers for heart stress or damage, and ruling out other conditions that may cause similar symptoms. Additionally, these tests also play a role in determining the type, severity, or stage of diastolic heart failure.

It's important to note that only healthcare professionals can diagnose diastolic heart failure accurately based on these tests and examinations. If you experience symptoms or have concerns about your heart health, it's best to consult with a doctor who can provide personalized advice and guidance tailored to your specific situation.
