Abstract
The present set of studies investigated the relationship between personality style and behavioral and cognitive responses immediately following the onset of coronary symptoms among first-time myocardial infarction (MI) patients. A systematic replication of key findings across this study series suggested that individual differences in help-seeking behavior among acute MI patients may, in part, he attributable to personality style differences. The findings appear to have special relevance for patients at high risk for infarction in view of recent studies of delay time and mortality rates in thrombolytic intervention trials.
