Depression state and relevant factors of patients with acute myocardial infarction

Abstract

Objective To investigate depression state in patients after acute myocardial infarction for more than 3 months and analyze the relevant factors. Methods The Zung SDS and general data questionnaire were systematically applied by to the 105 patients after acute myocardial infarction for 3 - 18 months by telephone visit. Results Among patients after acute myocardial infarction for more than 3 months, the incidence of depression was 21.9%. Age, history of hypertension, and occurrence of angina after discharges were different in the depression and non-depression patients after myocardial infraction on univariate analysis （ P 〈 0. 05 ）. Multiple logistic regression analysis identified age as an independent depression predictor after acute myocardial infraction for more than 3 months （ OR = 1. 067, 95% CI： 1. 002 - 1. 137）, and the incidence of depression were positively associated with age of patients by correction analysis （r = 0. 439, P = 0. 000）. Conclusions Patients after acute myocardial infarction for long time were still susceptible to depression. Age was the independent risk factor of depression ＇for patients with long term after acute myocardial infraction. Key words: Myocardial infarction; Depression; Relevant factors
