Blood tests are used to evaluate kidney and thyroid function as well as to check cholesterol levels and the presence of anemia. Your doctor may also order other tests to determine the cause and severity of your heart failure. ![]() 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. You’ll also get a complete physical exam. You’ll be asked if you smoke, take drugs, drink alcohol (and how much you drink), and about which medications you take. You’ll 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). Your doctor will ask you many questions about your symptoms and medical history. Your doctor can discuss which condition you have. Systolic dysfunction (or systolic heart failure) happens when the heart muscle doesn't contract with enough force, so there is less oxygen-rich blood pumped throughout the body.ĭiastolic dysfunction (or diastolic heart failure) happens when the heart contracts normally, but the ventricles don’t relax properly or are stiff, and less blood enters the heart during normal filling.Ī calculation done during an echocardiogram, called the ejection fraction (EF), is used to measure how well your heart pumps with each beat to help determine if systolic or diastolic dysfunction is present. They may or may not indicate a weakened heart. If you have heart failure, you may have one or all of these symptoms or you may have none of them.
