How Is Heart Failure Diagnosed?
Doctors will ask you many questions about your symptoms and your medical history. You will be asked about any conditions you have that may cause heart failure (such as coronary artery disease, angina, diabetes, heart valve disease, and high blood pressure).So it’s good to have your health data with you when you visit your doctor You will be asked if you smoke, take drugs, drink alcohol (and how much you drink), and about what drugs you take.
You will also get a complete physical exam. Your doctor will listen to your heart and look for signs of heart failure as well as other illnesses that may have caused your heart muscle to weaken or stiffen.
Your doctor may also order other tests to determine the cause and severity of your heart failure. These include:
- Blood tests. Blood tests are used to evaluate kidney and thyroid function as well as to check cholesterol levels and the presence of anemia. Anemia is a blood condition that occurs when there is not enough hemoglobin (the substance in red blood cells that enables the blood to transport oxygen through the body) in a person’s blood.
- B-type Natriuretic Peptide (BNP) blood test. BNP is a substance secreted from the heart in response to changes in blood pressure that occur when heart failure develops or worsens. BNP blood levels increase when heart failure symptoms worsen, and decrease when the heart failure condition is stable. The BNP level in a person with heart failure — even someone whose condition is stable — is higher than in a person with normal heart function. BNP levels do not necessarily correlate with the severity of heart failure.
- A chest X-ray will show the size of your heart and whether there is fluid build-up around the heart and lungs.
- Echocardiogram – This test shows the heart’s movement.
- Ejection fraction (EF). A test called the ejection fraction (EF) is used to measure how good your heart pumps with every beat to determine if systolic dysfunction or heart failure with preserved left ventricular function are present. Your doctor can discuss which condition is present in your heart.
- Electrocardiogram(EKG or ECG) – An EKG records the electrical impulses traveling through the heart.
- Cardiac catheterization.
- Stress Test.
