Dr. Lowell Steen treats a variety of patients, from those with blocked arteries, holes in the heart wall or with leaky heart valves. Some patients come in with symptoms like shortness of breath or chest discomfort and he can offer treatments to improve their quality of life. Dr. Steen explains that half of the cardiology patients seen at Loyola are treated for medical emergencies, such as a heart attack. We treat these emergency heart patients around the clock with our Heart Attack Rapid Response Team. Loyola ranks within the top 20 heart hospitals in the U.S. And that didn't happen by accident. The dedication and vision of our cardiologists, surgeons, nurses, support staff and administration made this happen.
