Supports ST/HR slope as marker of CAD severity in angina; leaves open prospective validation for clinical use.
Does the maximal ST/HR slope during exercise ECG accurately predict the presence and severity of coronary artery disease in patients with angina pectoris?
The maximal ST/HR slope during exercise ECG is a reliable index of myocardial ischemia that can predict the presence and severity of coronary artery disease.
