Why the study?
It was unknown whether post-exercise stress test troponin I increases help identify obstructive CAD and myocardial ischemia in patients with suspected stable angina.
Does the increase in troponin I after exercise stress test identify obstructive coronary artery disease in patients with suspected stable angina?
Population
50 patients with suspected stable angina admitted for elective coronary angiography
Comparison
Obstructive CAD vs no obstructive CAD, and positive vs negative exercise stress test
Design
Observational cohort study
Follow-up
12 h

Post-EST TnI rise does not identify obstructive CAD; leaves open its diagnostic utility in larger prospective studies.
Does the increase in troponin I after exercise stress test identify obstructive coronary artery disease in patients with suspected stable angina?
Troponin I increases after exercise stress testing regardless of the presence of obstructive coronary artery disease, limiting its diagnostic utility for stable angina.
