Why the study?
Does the maximal ST/HR slope during exercise ECG accurately predict the presence and severity of coronary artery disease in patients with anginal pain?

May aid noninvasive CAD severity grading in angina irrespective of beta-blockers; leaves open prospective validation before practice change.
Does the maximal ST/HR slope during exercise ECG accurately predict the presence and severity of coronary artery disease in patients with anginal pain?
The maximal ST/HR slope during exercise testing is a highly reliable index for predicting the presence and severity of coronary artery disease, outperforming usual exercise criteria even in patients on beta-blockers.
