Why the study?
Does the LF/HF ratio measured by ambulatory ECG immediately before coronary angiography predict the presence of coronary artery disease?
Does the LF/HF ratio measured by ambulatory ECG immediately before coronary angiography predict the presence of coronary artery disease?
The LF/HF ratio measured by a rapid ambulatory ECG immediately before coronary angiography may serve as a non-invasive predictor for the presence of coronary artery disease.

Association of pre-CAG LF/HF ratio with CAD supports hypothesis generation; does not yet justify routine use in risk stratification.
