What Are the Types of Heart Failure?
Systolic dysfunction (or systolic heart failure) occurs when the heart muscle doesn't contract with enough force, so there is less oxygen-rich blood that is pumped throughout the body.
Diastolic dysfunction (or diastolic heart failure) occurs when the heart contracts normally, but the ventricles do not relax properly or are stiff, and less blood enters the heart during normal filling.
A calculation done during an echocardiogram called the ejection fraction (EF) is used measure how well your heart pumps with each beat to help determine if systolic or diastolic dysfunction is present. Your doctor can discuss which condition you have.
How Is Heart Failure Diagnosed?
Your doctor will ask you many questions about your symptoms and 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). You will be asked if you smoke, take drugs, drink alcohol (and how much you drink), and about what medications you take.
You will also get a complete physical exam. Your doctor will listen to your heart and look for 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:
Other tests may be ordered, depending on your condition.
