Cardiology Services | Sunnybrook Medical Plaza

UnityPoint Health – St. Luke’s Cardiology Services and Cardiovascular Associates located at Sunnybrook Medical Plaza offers a convenient location to help you keep your heart healthy and strong.

With over 40 years of experience with Siouxland hearts, our knowledgeable team of cardiologists, cardiac nurses, technologists and other heart health professionals ensure the best outcome for every patient, every time.
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
We're 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.
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, we offer 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. 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
With individual exercise regimes and lifestyle training in nutrition and heart health, St. Luke's Pulmonary and Cardiac Rehabilitation 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.

EKGs are conveniently 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, then interpreted with 24-hours by one of our expert cardiologists. Reads requested on a stat basis are immediate. The EKG is stored in our archival system for patient security.
