Heart attacks can happen fast. One day you are living life and the next day you might be fighting for it. In the life-changing moments that require expert medical attention, turn to Siouxland's highest rated and only triple accredited heart team, UnityPoint Health - St. Luke's Cardiology Services and Cardiovascular Associates.


With 24/7 immediate heart care, St. Luke's and Cardiovascular Associates are saving lives.  Combining experienced care with the latest diagnostics and treatment, our goal is to provide the best outcome for cardiology patients.

The care our patients receive at  St. Luke's is our number one priority. That's why we're proud to be among the hospitals and agencies recognized by the American Heart Association's Mission: Lifeline program for our excellence in improving quality of patient care. 

In addition, St. Luke's has received the American College of Cardiology's NCDR ACTION Registry® Platinum Performance Achievement Award for 2018. St. Luke's demonstrated sustained achievement for eight consecutive quarters and met high performance standards for specific performance measures to receive the 2018 award. St. Luke's is one of only 203 hospitals nationwide to receive the honor.

Our outpatient services and screenings are available in two convenient locations: Sunnybrook Medical Plaza and the hospital campus. To schedule a heart screening or other outpatient procedures, call (712) 279-7979. Please note some procedures may require a physician referral.

If you think you are having a heart attack, call 9-1-1 and ask to be taken to St. Luke's hospital campus.

Our State-of-the-Art Cardiology Labs

St. Luke's cares for heart patients in dedicated electrophysiology (EP) and cardiac catheterization labs. Just steps away from St. Luke's Emergency Department (ED), the location of our labs is one of the reasons our door-to-balloon times are faster than the national average. This means less time is needed between the patient's arrival in the ED to when he/she is moved to the cardiac cath lab to receive heart care. In the end, this means less heart muscle will be lost and the patient's outcome will be better.

Acute, Diagnostic & Interventional Heart Care

St. Luke's and Cardiovascular Associates are ready to care for you 24 hours a day, 7 days a week with treatment options perfect for your individual needs. Treatment may include non-surgical procedures like angioplasty and stents, which can open blocked arteries in a less invasive way. Some patients are referred for electrophysiology (EP) services, which enhance a person's ability to study and treat patients with abnormal heartbeats without major surgery. And cardiac diagnostic tests like holter monitoring, echocardiograms and stress tests assess your heart health and identify cardiovascular disease. Many of these procedures are performed on a convenient, outpatient basis. Learn more about our cardiology services.

Coronary Care Unit

While many patient procedures can be performed on an outpatient basis, there are some procedures that call for added patient monitoring and care. For these patients, St. Luke's offers a dedicated coronary care unit on the hospital's fourth floor. The unit features calming artwork from the Wrede and Barbara Smith Art and Healing Project and state-of-the-art iBeds that offer extended patient comfort with music, translation and charting capabilities. In addition, the unit is staffed with health care professionals trained specifically in coronary care, providing expert, compassionate care for patients in critical recovery after a heart procedure. New monitoring and nurse calling systems, along with a sophisticated nurses' station, donated by Cardiovascular Associates, in memory of Dr. Tjeerdsma, are all amenities that make this unit ideal for patient recovery.

Cardiac Rehabilitation

Once a patient leaves the hospital, St. Luke's is still here to care for you. St. Luke's offers cardiac rehab programs at Sunnybrook Medical Plaza. With individual exercise regimes and lifestyle training in nutrition and heart health, St. Luke's cardiac rehab helps those recovering from heart conditions get healthy and stay healthy. You can also be seen for heart failure, vascular and pulmonary rehab.

Regional Outreach Care

For patient's outside the Sioux City area, St. Luke's and Cardiovascular Associates provide cardiology services in a dozen Iowa and Nebraska outreach locations.  On the road care is coordinated for efficiency and quality so you regularly have access to a cardiology technician. Remote services are performed at the hospital closest to you for patient convenience. The non-invasive studies include Echocardiography, Stress Tests, Vascular Doppler Studies and Holter Monitors.

The EKG Network also offers patient convenience. EKGs are taken at your local hospital for diagnosis of abnormal rhythms and damage to heart muscle. Tests are transmitted by phone line to St. Luke's and then interpreted promptly by one of our expert cardiologists. Routine reads are interpreted within 24-hours and reads requested on a stat basis are immediate. The EKG is then stored in St. Luke's archival system for patient security.
