SUBDIMA: Subclinical Depression in Acute Myocardial Infarction (SUBDIMA25)

Summary

This is an exploratory, prospective, non-profit study (SUBDIMA) designed to investigate the prevalence and potential prognostic significance of subclinical depression in patients admitted with a first acute myocardial infarction (AMI). Subclinical depression refers to the presence of mild depressive symptoms (PHQ-9 score 5-9) that do not meet DSM-5 TR criteria for major depressive disorder but may still be clinically relevant. The primary aim is to estimate the prevalence of subclinical depression in this setting. Secondary, exploratory objectives include evaluating associations with inflammatory and metabolic biomarkers, autonomic dysfunction, cardiac function, cognitive performance, quality of life, treatment adherence, and the risk of recurrent cardiovascular events over 12 months. The study is expected to generate new descriptive data that may inform future confirmatory trials and support early, personalized approaches to integrated cardiac and mental health care.
