Before a treatment plan for heart disease can be developed, the specific type of heart problem must be accurately diagnosed. A doctor may use a number of tests to diagnose heart disease, depending on the specific symptoms and the results of previous tests. These tests may include one or more of the following.
A physical exam is almost always the first step in diagnosing heart disease. The doctor will listen to the heart and lungs, check the pulse and blood pressure, and ask about both personal and family history.
The doctor will usually order a series of blood tests that may include one or more of the following:
A chest x-ray examines the heart, lungs, and bones to look for issues such as an enlarged heart, fluid in or around the lungs, blood vessel problems, congenital heart disease, or calcium build up. This test can be especially helpful in ruling out other possible causes of symptoms.
An ECG records electrical signals to detect irregularities in the heart structure and/or heart rhythm.
Holter monitors are portable devices worn to record a continuous ECG for 24 to 72 hours, detecting heart rhythm irregularities that may not be found during a single ECG exam.
An echocardiogram uses ultrasound to create detailed images of the heart’s function and structure.
Stress tests raise the heart rate through exercise or medication while ECG testing and imaging are used to see if the heart responds properly.
Cardiac catheterization involves having a flexible catheter inserted into a vein or artery in the leg, groin, or arm and guided using X-ray images to the heart, measuring pressure in the heart chambers and/or injecting dye to evaluate the blood flow in the heart, blood vessels, and valves.
Cardiac Computerized Tomography
A CT scan uses an X-ray tube that rotates around the body to collect images of the chest and heart, detecting problems or abnormalities.
Cardiac Magnetic Resonance Imaging
MRIs use a magnetic field to create pictures that help evaluate the condition of the heart.
After heart disease has been diagnosed, the doctor will discuss various treatment options depending on the specific type of condition and severity of the heart disease. In most cases, treatment will include lifestyle changes, medications, and/or medical procedures including surgery.
