There is an emerging field underlying the myocardial infarction with non-obstructive coronary arteries (MINOCA). The aim of this study was to evaluate the impact of psycho-emotional disorders and social habits in MINOCA patients.
The study included 95 consecutive patients diagnosed of MINOCA and 178 patients with myocardial infarction (MI) and obstructive lesions. MINOCA patients were included when they fulfilled the three main criteria: Accomplishment of the Third Universal Definition of Myocardial Infarction, absence of obstructive coronary arteries and no clinically overt specific cause for the acute presentation.
MINOCA patients had a higher frequency of previous psychiatric illnesses than the obstructive coronary arteries group (29.7 vs. 12.9%, p = 0.001). MINOCA patients recognized emotional stress in 75.7% of the cases, while only 32.1% of the obstructive related group did (p < 0.001). The relationship remained after excluding takotsubo syndrome from the analysis, also excluded were psychiatric diseases (27.9% vs. 12.9%, p < 0.01) and recognition of emotional stress (70.8% vs. 32.1%, p < 0.001). Social habits which could act as stress modulating showed no significant relation with MINOCA. CONCLUSIONS
Psycho-emotional disorders are related to MINOCA and they could act as risk factor. This relationship is maintained after excluding takotsubo from the analysis.
