Inability of the Submaximal Treadmill Stress Test to Predict the Location of Coronary Disease
Key result
Submaximal treadmill stress testing was unable to predict the specific coronary artery involved in patients with single-vessel disease, though positive tests indicated increased disease severity.
Why the study?
Does the submaximal treadmill stress test predict the specific location of coronary artery disease in patients undergoing coronary arteriography?

Implication
Submaximal stress testing should not guide vessel localization in single-vessel CAD; leaves open whether protocol refinements could enhance localization accuracy.
Key Points
- This research evaluates if submaximal treadmill stress tests can predict the location of coronary artery disease.
- Two hundred patients underwent submaximal treadmill stress tests and coronary arteriography within two months.
- Data was analyzed for associations between STST results and specific coronary artery disease locations.
- No association found between positive STST results and the specific coronary artery involved.
- Positive STSTs were linked to more severe coronary artery disease.
- Negative STSTs predominantly occurred in patients with single-vessel disease.

Submaximal treadmill stress testing can indicate the severity and extent of coronary artery disease but cannot reliably localize the specific vessel involved.

Kaplan et al. (1973) conducted an observational in Coronary artery disease (n=200). Submaximal treadmill stress test vs. Selective coronary arteriography was evaluated on Predictability of disease isolated to any given coronary vessel. Submaximal treadmill stress testing was unable to predict the specific coronary artery involved in patients with single-vessel disease, though positive tests indicated increased disease severity.
