Depression and myocardial injury in ST-segment elevation myocardial infarction:A cardiac magnetic resonance imaging study

摘要

cqvip:BACKGROUND Depression is common in patients with myocardial infarction and has been independently associated with adverse outcomes.However,the association between depression and myocardial injury on cardiac magnetic resonance(CMR)in patients with ST-segment elevation myocardial infarction(STEMI)has still not been assessed.AIM To assess the association between depression and myocardial injury on CMR in patients with STEMI.METHODS A total of 107 STEMI patients undergoing primary percutaneous coronary intervention(P-PCI)were analyzed in this prospectivecohort study.Each subject completed the Patient Health Questionnaire-9(PHQ-9)to assess the presence and severity of depressive symptoms.CMR was performed at a median of 3 d after PPCI for quantifying post-MI myocardial injury.Correlations between depression identified by the PHQ-9 and myocardial injury measured on CMR were assessed.RESULTS In this study,19 patients(17.8%)were diagnosed with major depression identified by the PHQ-9≥10.PHQ-9 was analyzed both as a continuous variable and dichotomous variable.After multivariable adjustment,the proportion of patients with large infarction size was significantly higher in the major depression group(PHQ-9≥10)(OR:4.840,95%CI:1.122–20.868,P=0.034).When the PHQ-9 was evaluated as a continuous variable,after multivariable adjustment,an increased PHQ-9 score was associated with an increased risk of large infarction size(OR:1.226,95%CI:1.073–1.401,P=0.003).CONCLUSION In patients with STEMI undergoing PCI,depression was independently associated with a large infarction size.
