Supports retaining CPK thresholds for AMI after submaximal exercise; leaves open confirmation in larger or maximal-effort cohorts.
Does submaximal physical exercise increase serum CPK levels enough to impair the diagnosis of acute myocardial infarction in untrained individuals?
Submaximal physical exercise causes minimal CPK elevation, indicating that recent heavy physical work rarely confounds the CPK-based diagnosis of acute myocardial infarction.
Forssell et al. (1975) studied this question.
