Why the study?
Does the maximum ST segment/heart rate slope during exercise testing accurately predict the presence and severity of coronary artery disease in patients presenting with chest pain?
Population
78 patients presenting with chest pain

Low specificity and frequent uncalculability limit diagnostic use of ST/HR slope; leaves open incremental value in prospective cohorts.
Does the maximum ST segment/heart rate slope during exercise testing accurately predict the presence and severity of coronary artery disease in patients presenting with chest pain?
The maximum ST segment/heart rate slope during exercise testing is limited by a high rate of uncalculability and low specificity for predicting the presence and severity of coronary artery disease.
