Dr. John Lopez, an interventional cardiologist, talks about Loyola's Rapid Response program, which treats heart attack patients within an average of 30 minutes, well below the national average of an hour. Loyola has the catheter lab and cardiology nurses and doctors available 24/7 because no one plans a heart attack. He enjoys conducting some of the leading-edge research that Loyola is known for. Loyola was one of the few centers selected to research the success rates of minimally invasive heart valve replacement therapy. The procedure is now offered to all eligible patients, not just those in the clinical trial. He sees such a turnaround in the health in his patients and enjoys seeing them back living a normal life.
