Why the study?
Does cardiac troponin I measurement compared to cardiac troponin T measurement improve diagnostic accuracy for acute myocardial infarction in general medicine patients?
Population
98 consecutive patients admitted to General Medicine Divisions with suspected acute myocardial infarction
Comparison
Cardiac troponin I (cTnI) measurement vs Cardiac troponin T (cTnT) measurement
Design
Cross-sectional, Diagnoses were made without knowledge of troponin results

High sensitivity supports either troponin for AMI exclusion in general medicine; cross-sectional data leaves open any cTnI preference.
Does cardiac troponin I measurement compared to cardiac troponin T measurement improve diagnostic accuracy for acute myocardial infarction in general medicine patients?
Both cTnI and cTnT are highly sensitive for detecting AMI in general medicine patients, with cTnI showing marginally higher specificity.
