Study 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.

Read the detailed description

Depression is a recognized risk factor for adverse outcomes in patients with acute coronary syndromes. While most studies have focused on major depressive disorder, subclinical depression (defined as PHQ-9 scores between 5 and 9 in the absence of DSM-5 TR criteria for major depression) remains poorly characterized. Its prevalence in patients with a first acute myocardial infarction (AMI) is largely unknown, as are its potential associations with clinical, biological, and psychosocial outcomes.

The SUBDIMA study is a prospective, exploratory, single-center, non-profit clinical investigation conducted at Fondazione Policlinico Universitario A. Gemelli IRCCS. Consecutively admitted patients with a first AMI will undergo systematic screening with the PHQ-9 and a structured clinical assessment to exclude major depression. Based on these evaluations, patients will be classified into two groups: with or without subclinical depression. All participants will be followed for 12 months, with visits at baseline, 3 months, and 12 months, and intermediate phone contacts at 6 and 9 months.

The primary aim of the study is descriptive: to estimate the prevalence of subclinical depression in this population. Secondary, exploratory aims are to examine potential associations between subclinical depression and:

  • inflammatory and metabolic biomarkers,
  • measures of autonomic dysfunction (e.g., heart rate variability),
  • cardiac function parameters (e.g., echocardiographic strain indices, NT-proBNP),
  • cognitive and anxiety assessments,
  • health-related quality of life and lifestyle factors,
  • adherence to treatment,
  • and the incidence of recurrent cardiovascular events during follow-up.

Given its exploratory design, the study is not powered to test confirmatory hypotheses. Instead, it is expected to provide novel descriptive data that will inform the design of future confirmatory trials and contribute to the integration of psychosocial screening in cardiology care pathways.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age ≥18 years
  • Hospital admission for first acute myocardial infarction (STEMI or NSTEMI) within 7 days from the index event
  • PHQ-9 administered at screening
  • (MMSE) score ≥26
  • Written obtained

Exclusion criteria

Exclusion Criteria:

  • Previous history of acute myocardial infarction
  • Diagnosis of major depression according to TR criteria
  • Severe cognitive impairment ( \<26)
  • Severe comorbidities with expected survival \<12 months
  • Inability to participate in scheduled follow-up assessments
  • Refusal or inability to provide
  • Concurrent participation in other interventional clinical studies that could interfere with study outcomes
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

MMSE and MoCA

Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2025 (actual). Primary completion is estimated for Oct 2026, 12 months after the start.

Of 3,471 non-industry interventional studies with no phase under Depression, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 41. This study's planned 12 months is below that.

Counting every sponsor, half of 3,569 studies reached it within 21 months; a quarter within 9 and three quarters within 41.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 4, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
