Why is it important?

This is not an experimental study, but describes how the results of this clinical service guide decision-making and treatment of patients with coronary artery disease.


The paper describes experiences with patients with real clinical problems faced by cardiologists in daily practice. Questions like did this patient have a heart attack, how much of the heart was damaged, is it safe to treat the patients with medications alone or does the patient need a coronary stenting procedure? are answered with this test. The paper also tracks what happens to these patients up to 14 months after the test results were used to guide treatment. Were they safe? Did they have more heart attacks are some examples.
