Why the study?
PR interval prolongation is frequent in clinical practice, but few studies have evaluated its association with significant CAD in hospitalized patients with NSTEMI and unstable angina.
Does a prolonged PR interval associate with significant coronary artery disease in patients with NSTEMI or unstable angina?
Population
205 patients with NSTEMI or unstable angina
Comparison
Prolonged PR interval (>=200 ms) vs normal PR interval (<200 ms)

May flag CAD risk on admission ECG in NSTEMI; hypothesis-generating and requires prospective validation.
Does a prolonged PR interval associate with significant coronary artery disease in patients with NSTEMI or unstable angina?
A prolonged PR interval on admission ECG in patients with NSTEMI or unstable angina is independently associated with significant coronary artery disease.
