Is there any difference between the early age myocardial infarction and late age myocardial infarction in terms of psychiatric morbidity in patients who have survived acute myocardial infarction?

ABSTRACT

OBJECTIVE: We aimed to compare the rates of psychiatric morbidity in patients who had early age and late age MI in patients who have survived acute myocardial infarction? METHODS: One hundred sixteen patients who were hospitalized in the coronary care unit were included in the study. Psychiatric assessment of the patients was carried out within 1-6months post-MI. Psychiatric interviews were conducted with the Structured Clinical Interview for DSM-IV (SCID-I). Also used were the Beck Depression Inventory (BDI), Spielberger State-Trait Anxiety Inventory (STAI), and Health Anxiety Inventory (HAI). RESULTS: A total of 116 patients were divided into two groups according to age as an early age myocardial infarction group (EA-MI) and a late age myocardial infarction group (LA-MI). The EA-MI group included 24 patients 45years of age and under. The LA-MI group included 92 patients over 45years of age. Current psychiatric disorders, lifetime psychiatric disorders and lifetime depressive disorders were significantly more frequent in the EA-MI group than in the LA-MI group. CONCLUSION: EA-MI patients have experienced a depressive episode prior to the onset of the MI, whereas in the LA-MI group, the patients typically experienced depressive episodes after MI. Our findings suggest that depression may increase the risk of MI at an early age.
