Key result
The combined use of dynamic heart rate and systolic blood pressure characteristics with usual early exercise test data predicted early cardiac death in 80% of cases after myocardial infarction.
Why the study?
Does the analysis of dynamic characteristics of heart rate and systolic blood pressure during early exercise testing improve the prediction of fatal coronary events in patients after acute myocardial infarction?
Population
894 patients who underwent submaximal exercise testing within 3 weeks of acute myocardial infarction
Comparison
Analysis of dynamic characteristics of heart… vs Usual data of early exercise test

Does the analysis of dynamic characteristics of heart rate and systolic blood pressure during early exercise testing improve the prediction of fatal coronary events in patients after acute myocardial infarction?
Dynamic characteristics of heart rate and systolic blood pressure during early exercise testing post-MI improve the prediction of early cardiac death compared to ST depression alone.
t et al. (2004) conducted a cohort in acute myocardial infarction (n=894). Dynamic characteristics of heart rate and systolic blood pressure during early exercise test was evaluated on early cardiac death. The combined use of dynamic heart rate and systolic blood pressure characteristics with usual early exercise test data predicted early cardiac death in 80% of cases after myocardial infarction.
