[The influence of myocardial infarction on depression in patients with coronary artery disease].
The recent studies revealed the relation between depression and the prevalence of cardio-vascular diseases, as well as their complications. However the correlation between the risk factors of coronary artery disease and depression in patients suffering from cardio-vascular disorders hasn't been sufficiently examined. The history of myocardial infarction (MI) is a well known factor, which increases mortality. The aim of the study was to determine if there was any relation between the history of myocardial infarction and depression rate in patients with cardio-vascular diseases.


METHODS
The study involved 163 patients, 75 women and 88 men, aged 29 to 86 years (mean age 60.75 +/- 11.01), hospitalised for the purpose of undergoing coronary angiography or percutaneous transluminal coronary angioplasty (PTCA). Before the procedure, the symptoms of depression were evaluated in all the patients. Each of them filled the Beck's scale inquiry-sheet. Two groups of patients were detached: group A consisted of patients with the history of MI (n = 96), group B-of patients with negative history of MI, diabetes who had never undergone PCI, or coronary artery bypass graft (CABG) before (n = 42). The control group (group C) consisted of 75 individuals, aged 20 to 80 (mean age 45 +/- 11.14 y), who felt healthy according to WHO criteria, weren't on any medication, hadn't been hospitalised in previous 5 years (at any reason) and in whom cardio-vascular diseases and their modificable risk factors were excluded.


RESULTS
The median of the Beck's score of depression for group A (9 points) was significantly higher (Wilcoxon test), than for group B (6.5 points), p < 0.02 and for the group C (3 points), p < 0.05. (tab. 1).


CONCLUSIONS
In patients with cardio-vascular disorders depression is more frequent, than in health individuals. History of MI increases the prevalence of depression.
