Coronary Angiogram in Grand Rapids, Michigan

A coronary angiogram is a specialized heart test that uses moving (dynamic) X‑ray images and contrast dye to see how blood flows through your coronary arteries. Cardiologists in Grand Rapids use this procedure to check for:

  • Narrowing or blockages in the coronary arteries
  • Problems with the heart muscle
  • Issues with the heart valves
  • Certain structural heart defects

In the Grand Rapids area, coronary angiograms are commonly performed at major heart centers such as Corewell Health (formerly Spectrum Health), Trinity Health Grand Rapids, Metro Health – University of Michigan Health, and Mercy Health.

What Is a Coronary Angiogram (Cardiac Catheterization)?

Another term: Cardiac catheterization

A coronary angiogram is often called a cardiac catheterization (“cardiac cath”). The test is done in a special room called a cardiac catheterization laboratory (cath lab), which is similar to an operating room.

During the procedure:

  • A slender catheter (a thin, flexible, hollow tube) is inserted into an artery in your wrist or groin.
  • The catheter is gently guided through your largest artery (the aorta) to reach the coronary arteries that supply blood to your heart.
  • A special X‑ray contrast dye is injected through the catheter.
  • Dynamic X‑ray images (angiograms) are taken as the dye moves through your heart arteries.

You cannot feel the catheter moving inside your blood vessels or heart because there are not enough nerves in these structures.

Why Coronary Angiograms Are Done in Grand Rapids

Cardiologists in Grand Rapids may recommend a coronary angiogram if you have:

  • Chest pain (angina), especially with activity or in cold Michigan winters
  • Abnormal results on a stress test, echocardiogram, or CT scan
  • Unexplained shortness of breath, dizziness, or fainting
  • A known history of coronary artery disease
  • Symptoms that suggest a heart attack or unstable angina

Beyond coronary artery disease, a coronary angiogram can help diagnose:

  • Aneurysm – abnormal ballooning of a heart chamber or vessel wall
  • Heart arrhythmias – irregular heartbeats
  • Congenital (birth) defects – such as a hole in the heart or abnormal connections between vessels

Because heart disease is a leading health concern in Michigan, especially with risk factors like high cholesterol, diabetes, smoking, and sedentary lifestyle during long winters, coronary angiograms are a key tool for accurate diagnosis and treatment planning in the Grand Rapids region.

Medical Issues to Discuss Before a Coronary Angiogram

Before your angiogram, your Grand Rapids cardiologist will review:

  • Your medical history, including:
    • Heart disease, stroke, high blood pressure, diabetes
    • Asthma or other lung problems
    • Kidney disease (important because of the contrast dye)
    • Any bleeding disorders
  • Your medications, especially:
    • Blood thinners (warfarin, apixaban, rivaroxaban, clopidogrel, aspirin)
    • Diabetes medications
    • Over‑the‑counter drugs and supplements
  • Allergies, including:
    • Previous reaction to contrast dye
    • Allergies to iodine, shellfish (not a direct contraindication but often discussed), or medications
  • Pregnancy status for women of childbearing age

You may be asked to:

  • Stop or adjust certain medications (especially blood thinners) before the test
  • Fast for 4–6 hours before your procedure (no food or drink)

Your care team may also order:

  • Blood tests
  • Electrocardiogram (ECG)
  • Chest X‑ray
  • Cardiac CT or other imaging if needed

How to Prepare in Grand Rapids, MI

In addition to medical instructions, consider:

  • Transportation: You will usually not be allowed to drive yourself home. Arrange a ride with family, a friend, or a local ride service in Grand Rapids.
  • Weather planning: In winter, allow extra travel time for snow and ice, and wear warm, loose clothing you can easily change out of at the hospital.
  • Insurance and ID: Bring your insurance card, photo ID, and a list of medications.

Hospitals in Grand Rapids such as Corewell Health Butterworth Hospital or Trinity Health Grand Rapids will provide specific pre‑procedure instructions based on their protocols.

What Happens During a Coronary Angiogram

Most diagnostic coronary angiograms in Grand Rapids are done as day procedures, meaning you go home the same day.

Before entering the cath lab

  • A nurse reviews your medical history and consent forms.
  • You change into a hospital gown.
  • An IV line (cannula) is placed in your arm for fluids and medications.
  • Hair may be shaved from your wrist and/or groin to keep the area clean.

In the cath lab

You will:

  • Lie on a special X‑ray table.
  • Be connected to a heart monitor to record your heart rhythm and vital signs.
  • Have your wrist and/or groin cleaned with antiseptic and covered with sterile drapes.

The cardiologist will:

  1. Inject a small amount of local anesthetic at the access site (wrist or groin) to numb the skin.
  2. Insert a small tube into the artery and then guide the catheter through the blood vessels to the heart using real‑time X‑ray images on a monitor.
  3. Inject contrast dye through the catheter into the coronary arteries.
  4. Record dynamic X‑ray images as the dye flows through the arteries.

You may:

  • Feel a warm flush or tingling when the contrast is injected—this is normal and passes quickly.
  • Be asked to take a deep breath or hold your breath briefly during imaging.

The angiogram typically lasts about 30–40 minutes, though it can take longer if additional procedures (like angioplasty) are performed.

Immediately After the Coronary Angiogram

After the procedure, you will be moved to a recovery area:

  • Your blood pressure, heart rate, breathing, and access site (wrist or groin) are checked regularly.
  • The catheter is removed, and pressure is applied to prevent bleeding. A bandage or compression device will be placed on the site.
  • You may receive IV fluids for a short time.
  • You will be encouraged to eat and drink as soon as you feel able, unless your cardiologist advises otherwise.

Depending on the access site and your condition:

  • You may need to lie flat for a few hours if the groin was used.
  • You may be allowed to sit up after about four hours.
  • Many patients are discharged within 4–6 hours after recovery if there are no complications.

Your cardiologist will usually give you initial results before you leave and explain if any immediate treatment was done, such as angioplasty or stent placement.

Possible Complications of a Coronary Angiogram

Coronary angiograms are generally safe, especially in experienced centers like those in Grand Rapids, but all procedures carry some risk. Possible complications include:

  • Allergic reaction to contrast dye
    • Hives, itchy skin, or more serious reactions (rare)
  • Bleeding or bruising at the wrist or groin access site
  • Infection at the access site
  • Heart arrhythmia (irregular heartbeat)
  • Heart attack (rare)
  • Stroke (rare)
  • Kidney problems related to the contrast dye, especially in people with existing kidney disease

Your cardiology team will discuss your individual risk and how they will monitor and manage these possibilities.

Taking Care of Yourself at Home After a Coronary Angiogram

Your Grand Rapids cardiologist and nurses will give you written discharge instructions. General suggestions include:

  • Rest as much as you can for the first 24–48 hours.
  • Avoid standing for long periods in the first couple of days.
  • Avoid heavy lifting and strenuous exercise for at least one week, or as directed.
  • Keep the bandage clean and dry. Follow instructions for when you can shower.
  • Drink plenty of fluids (usually starting about 8 hours after the procedure, unless told otherwise) to help flush the contrast dye from your body.

See your doctor if you suspect infection

Call your doctor or seek urgent care if you notice:

  • Redness, warmth, or increasing pain at the access site
  • Swelling or a growing lump at the wrist or groin
  • Discharge or pus from the wound
  • Fever or chills
  • Numbness, tingling, or color changes in the arm or leg used for access

If you develop chest pain, shortness of breath, sudden weakness, or trouble speaking, call 911 or go to the nearest emergency department (for example, at Corewell Health Butterworth Hospital or Trinity Health Grand Rapids).

You will need a follow‑up appointment with your cardiologist or primary care doctor to:

  • Review the final angiogram results
  • Discuss long‑term treatment and lifestyle changes

Treatment Options Based on Angiogram Results

Angioplasty and stent placement

If your angiogram shows narrowed or blocked coronary arteries, your cardiologist may be able to treat them during the same procedure using:

  • Angioplasty – a special balloon‑tipped catheter is guided into the narrowed artery and inflated to widen it.
  • Stent placement – a small metal mesh tube (stent) is placed to keep the artery open.

These procedures are commonly performed in Grand Rapids cath labs and may help relieve chest pain and reduce the risk of heart attack.

Coronary artery bypass graft surgery (CABG)

If blockages are severe or widespread, your cardiologist may recommend coronary artery bypass surgery, often done at major heart centers in Grand Rapids. This involves:

  • Using veins or arteries from other parts of your body
  • Grafting them onto the heart to “bypass” the blocked arteries and restore blood flow

Medications and lifestyle changes

Regardless of whether a procedure is done, you may be advised to:

  • Start or adjust cholesterol‑lowering medications (statins)
  • Take aspirin or other blood thinners as prescribed
  • Control blood pressure and blood sugar
  • Quit smoking – local support is available through the Kent County Health Department and Grand Rapids Public Health programs
  • Follow a heart‑healthy, cholesterol‑lowering diet
  • Increase physical activity safely, often with guidance from cardiac rehabilitation programs in Grand Rapids

Long‑Term Outlook After a Coronary Angiogram

A coronary angiogram is currently the most accurate test for diagnosing many heart problems, including coronary artery disease. Your long‑term outlook depends on:

  • The severity and location of any blockages
  • How quickly treatment is started
  • Your commitment to lifestyle changes
  • Control of risk factors like high cholesterol, high blood pressure, diabetes, and smoking

In West Michigan, where long winters can limit outdoor activity, it is especially important to:

  • Find safe indoor exercise options (gym, home equipment, mall walking)
  • Maintain a balanced diet even during colder months
  • Keep regular follow‑up appointments with your Grand Rapids healthcare providers

Your cardiologist may also recommend other heart tests over time, such as:

  • Exercise stress test
  • Echocardiogram (heart ultrasound)
  • CT scan or cardiac CT angiography
  • MRI scan of the heart
