A factor analysis was conducted to characterize perception of stress in patients with acute myocardial infarction

Actor analysis	ANOVA p-value: < 0.0001	Post-hoc-t-test (Bonferroni adjustment) p-values
	mean (SD)	Factor 2	Factor 3	Factor 4
Factor 1: Job/finances	1.49 (0.99)	1	< 0.0001	0.00253
Factor 2: Family/friends/social environment	1.48 (0.99)	–	< 0.0001	0.00049
Factor 3: Fear of infection with Sars-Cov-2	2.01 (1.13)	–	–	0.00260
Factor 4: Society/social life	1.74 (1.11)	–	–	–

The factor analysis revealed an optimum of 4 factors, which are the following: Factor 1: job/finances; Factor 2: family/friends/social environment; Factor 3: fear of infection with Sars-Cov-2; Factor 4: society/social life. An analysis of variance (ANOVA) revealed significant differences among the factors. Post-hoc t-tests were performed to further analyze differences between each of the 4 factors. Factor 3 had significant higher values than the remaining factors. Factor 4 was rated significantly higher than factor 2 and 1. The two latter ones did no vary significantly from each other
