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?

ObjectiveWe 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?MethodsOne 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 1–6 months 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).ResultsA 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 45 years of age and under. The LA-MI group included 92 patients over 45 years 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.ConclusionEA-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.
