Implication

May aid CAD diagnosis across pre-test probabilities; leaves open prospective validation before practice change.

Key Points

To assess the diagnostic value of combining exercise electrocardiography and postexertional thallium scintigraphy using a Bayesian framework in patients suspected of having coronary artery disease.
Evaluated 160 patients (130 men and 30 women; N=160) without previous myocardial infarction who underwent coronary arteriography.
Stratified patients into two pre-test disease prevalence groups: Group 1 with typical angina pectoris (90% CAD prevalence, n=98 men) and Group 2 with atypical angina pectoris (18% CAD prevalence, n=32 men and 30 women).
Baseline CAD prevalence varied markedly according to symptoms and sex, presenting at 90% in typical angina versus 18% in atypical angina.
Diagnostic test performance and post-test disease probabilities were evaluated across these distinct prevalence cohorts, though detailed quantitative accuracy metrics were not reported in the abstract.

Structured PICO

Does combining exertional ECG and postexertional thallium (201T1) scintigraphy provide diagnostic value in patients suspected of having coronary artery disease without previous myocardial infarction?

Population

160 patients (130 men and 30 women) suspected of having coronary artery disease (CAD) without previous myocardial infarction who underwent a coronary arteriography. Subdivided into Group 1 (98 men with typical angina pectoris, high prevalence of CAD = 90%) and Group 2 (32 men and 30 women with atypical angina pectoris, low prevalence of CAD = 18%).

Intervention

Combining exertional ECG and postexertional thallium (201T1) scintigraphy

Comparator

Coronary arteriography (reference standard)
