Acute coronary syndrome and stress: Is there a relationship?

Acute coronary syndrome (ACS) is the result of a complex pathophysiological process with various dynamic factors. The 10-item Perceived Stress Scale (PSS-10) is a validated instrument for estimating stress levels in clinical practice and may be useful in the assessment of ACS. We carried out a single-center prospective study engaging patients hospitalized with ACS between March 20, 2019 and March 3, 2020. The PSS-10 was completed during the hospitalization period. The ACS group was compared to a control group (the general Portuguese population), and a subanalysis in the stress group were then performed. A total of 171 patients with ACS were included, of whom 36.5% presented ST-elevation myocardial infarction (STEMI), 38.1% were female and the mean PSS score was 19.5±7.1. Females in the control group scored 16.6±6.3 on the PSS-10 and control males scored 13.4±6.5. The female population with ACS scored 22.8±9.8 on the PSS-10 (p
