Subclinical depression in people after a first heart attack (SUBDIMA25)

SUBDIMA Study: Subclinical Depression in Myocardial Infarction -Prevalence, Predictors and Prognostic Impact.

Not applicable Interventional Fondazione Policlinico Universitario Agostino Gemelli IRCCS · NCT07492537

This project will test how common mild depressive symptoms are in adults hospitalized for a first heart attack and whether those symptoms relate to biomarkers, heart function, and recovery over the next year.

What this trial studies

SUBDIMA is a prospective, single-center, exploratory investigation enrolling consecutive adults admitted with a first acute myocardial infarction who are screened with the PHQ-9 and a structured clinical interview to exclude major depressive disorder. Participants will be classified as having subclinical depression (PHQ-9 5–9 without DSM-5 TR major depression) or not, then followed for 12 months with in-person visits at baseline, 3 months, and 12 months and phone contacts at 6 and 9 months. Secondary, exploratory analyses will examine associations between subclinical depressive symptoms and inflammatory and metabolic biomarkers, autonomic function (e.g., heart rate variability), cardiac function measures, cognitive performance, quality of life, treatment adherence, and recurrent cardiovascular events. The study is descriptive and intended to generate data to guide future confirmatory trials and integrated cardiac–mental health approaches.

Who should consider this trial

Good fit: Adults aged 18 or older admitted for a first STEMI or NSTEMI within 7 days who can complete the PHQ-9 and MMSE (score ≥26) and are able to provide informed consent are ideal candidates.

Not a fit: Patients with prior myocardial infarction, current major depressive disorder, severe cognitive impairment (MMSE <26), limited life expectancy <12 months, inability to attend follow-up, or participation in conflicting interventional trials are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the findings could help identify patients with mild depressive symptoms who might benefit from earlier integrated cardiac and mental health support to improve recovery and reduce the risk of recurrent events.

How similar studies have performed: Prior research has linked major depression after myocardial infarction to worse outcomes, but studies specifically targeting subclinical depressive symptoms in this setting are limited and largely exploratory.
