The electrocardiographic exercise test in a population with reduced workup bias: diagnostic performance, computerized interpretation, and multivariable prediction. Veterans Affairs Cooperative Study in Health Services #016 (QUEXTA) Study Group. Quantitative Exercise Testing and Angiography.

Background: Empirical scores, computerized ST-segment measurements, and equations have been proposed as tools for improving the diagnostic performance of the exercise test.

Objective: To compare the diagnostic utility of these scores, measurements, and equations with that of visual ST-segment measurements in patients with reduced workup bias.

Design: Prospective analysis.

Prediction of cardiovascular death in men undergoing noninvasive evaluation for coronary artery disease.

Objective: To develop prediction rules from clinical and exercise test data identifying patients at high and low risk for cardiovascular events among a group of male veterans.

Design: Prognostic study with prospective gathering of data and routine follow-up of consecutive patients referred for exercise testing. Patients only underwent noninvasive evaluation for coronary artery disease.

Incidence of complications from coronary angiography in 463 USAF aviators.

Over 600 fliers have had coronary angiography at the USAF School of Aerospace Medicine since 1971. This paper concerns the incidence of complications, long- and short-term, on the first 463. Information on short-term complications was compiled from computerized data storage and included all 463 patients.
