Diagnosing Heart Disease


Referrals & Appointments

Find a Specialist

Edward Heart Hospital offers cardiac diagnostic testing services at four locations for your convenience, including Naperville, Plainfield, Bolingbrook and Yorkville. To schedule an appointment at any of these locations, call (630) 527-2800 or 1-877-45-HEART.

Time is muscle

Many patients who come to the Emergency Department with chest pain are sent to the Cath Lab for further evaluation. If a blockage is found, a cardiologist can open the blocked vessel with a balloon right in the Cath Lab. This is called an angioplasty. It's important to get a blockage opened quickly to save heart muscle from being damaged. Because Edward Heart Hospital has an on-site Cath Lab, we typically perform an angioplasty within 75 minutes of arrival at the Emergency Department, which puts us in the top 10% of the country.

What is a Cardiac Cath Lab?
Over 1,000 patients visit our Cath Lab each year. A cardiac catheterization is an x-ray of the heart that involves inserting a thin flexible tube, or catheter, into a blood vessel in the groin or arm. The tube is threaded through the blood vessel into the heart. Colorless "dye" is injected into the heart and a movie is taken of the heart and blood vessels to show any blockages or other heart abnormalities. Philips Medical Systems selected our Cardiac Cath Lab as one of only three hospitals in the country to offer their flat detector x-ray technology. The equipment takes sharper, clearer images and makes it possible for our doctors to see and work in some of the smallest parts of the heart. 

64-slice CT angiography
This test utilizes very fast x-ray technology to take a three-dimensional image of the beating heart. It is minimally-invasive so it does not require sedation like a cardiac catheterization. Dye is simply injected into an arm prior to the test. It is typically used to diagnose more complex conditions like abdominal aortic aneurysm or congenital heart disease.

Cardiac stress testing (stress echocardiogram)
This test will provide information regarding your level of exercise tolerance, the ability of your heart to respond appropriately to an increased workload, and the size of the chambers of the heart and its pumping action.

Coronary angiography (and peripheral angiography)
In this procedure, a catheter is placed in the heart, leg or arm, to detect problems with the heart. This procedure is generally done after a person experiences chest pains or other symptoms that could signify a problem with the heart. Cardiac catheterization is also offered at Heart Hospital as a part of outpatient care.

The electrocardiogram is a test used to evaluate the rhythm and activity of the heart.

Electrophysiology studies
An electrophysiology study is a procedure that examines the heart’s electrical activity and pathways. It is an invasive test, similar to a cardiac catheterization. Click here to learn more.

2D and 3D echocardiography
Echocardiography is a form of ultrasound that uses high-frequency sound waves to examine the size, shape, and motion of the heart. The latest technology takes three-dimensional (3D) images that are useful for evaluating the strength of the heart and holes in the heart.

Holter monitor
A holter monitor records the electrical activity of the heart for a 24-hour period of time. This allows detection of any irregularities and/or abnormalities in the heart's rhythm during normal activities.

Nuclear studies
Nuclear studies illustrate the nuclear medicine deposited in the heart muscle which is consistent with blood flow. Those findings will help to evaluate the heart for the presence and severity of atherosclerotic heart disease.

Peripheral vascular ultrasound
A procedure that uses sound waves to examine various parts of the body, including: aorta and other abdominal arteries and veins, blood vessels in extremities (arms and legs) and blood vessels in extra-cranial cerebrovascular system.
