Why the study?
Does the Stress-Recovery Index improve the identification of multivessel disease in patients after acute myocardial infarction compared to conventional parameters?
Population
70 patients evaluated 2-3 weeks after uncomplicated acute myocardial infarction, with cardioactive therapy…
Comparison
Stress-Recovery Index derived from ST depression… vs Conventional parameters of ST segment depression.
Design
Cohort
Key result
The Stress-Recovery Index < -5 mm x beats.min-1 predicted multivessel disease after acute myocardial infarction with 65% sensitivity and 81% specificity.

Does the Stress-Recovery Index improve the identification of multivessel disease in patients after acute myocardial infarction compared to conventional parameters?
The Stress-Recovery Index during exercise testing improves the diagnostic sensitivity for identifying multivessel coronary artery disease in post-MI patients without compromising specificity.
Bigi et al. (1994) conducted an observational in acute myocardial infarction (AMI) (n=70). Stress-Recovery Index (SRI) vs. other conventional parameters was evaluated on identification of multivessel disease (MVD). The Stress-Recovery Index < -5 mm x beats.min-1 predicted multivessel disease after acute myocardial infarction with 65% sensitivity and 81% specificity.
