Perceived stress level is associated with coronary artery disease severity in patients with ST-segment elevation myocardial infarction

Stress is known to be a significant risk factor for coronary atherosclerosis and adverse cardiovascular events; however, the stress-related coronary atherosclerotic burden has not yet been investigated. The aim of this study was to investigate the relationship between the Perceived Stress Scale (PSS) and the SYNTAX scores in patients with ST-segment elevation myocardial infarction (STEMI). A total of 440 patients with STEMI were prospectively enrolled and divided into 2 groups according to the PSS score with a ROC curve analysis cut-off value of 17.5. In all, 361 patients with a low PSS score were categorized as Group 1 and 79 patients with a high PSS score were categorized as Group 2. The SYNTAX score [Group 1, 16.0 (10.0-22.5); Group 2, 22.5 (15.0-25.5); p
