Study summary

This multi-site international clinical research project is a collaboration between investigators from multiple institutions in the USA, Canada, and Europe. Approximately 7 to 11 sites will participate and provide data for analysis. Clinical operations (for data collection and analysis) across sites will be managed by Stanford. The study purpose is to determine differences in clinical and imaging presentation, in-hospital management and prognosis in peripartum and non-peripartum SCAD patients.

Read the detailed description

There is a reason to believe that female sex hormone fluctuations during the peripartum period are linked with the occurrence of SCAD, and may be associated with a distinctive clinical presentation. In addition, symptoms of psychological distress may be linked to the development of SCAD and post-event distress is higher in SCAD patients than in those with coronary artery disease (CAD).

The primary objective is to determine differences in clinical and imaging presentation, in-hospital management and prognosis in peri-partum and non-peri-partum SCAD patients. At the methodological level, the purpose is to apply a systematic image analysis protocol for classifying SCAD lesions and to pool data to achieve adequate statistical power.

The secondary objective is to gather more information about psychological and psychosocial factors in SCAD patients. Specifically, to assess pre-event stress and psychological diagnoses and determine differences in post-event distress between peripartum and non-peripartum SCAD.

It is expected that these aims will result in two important outcomes. First, implementation of a systematic image analysis protocol for SCAD data will lead to improved reliability and, we expect, the detection of clinically meaningful differences between peripartum and non-peripartum SCAD. These differences may align with potential causal mechanisms for further study to ultimately better understand SCAD and develop treatment(s). Second, by characterizing the psychological distress experienced by SCAD patients, and differences between patients who experienced peripartum vs. non-peripartum SCAD, psychosocial risk factors may be identified and psychosocial interventions can be tailored to meet the needs of this unique patient population.

This is an observational study using cross-sectional design. There are two main components: a retrospective collection of medical history pertaining to SCAD event and prospective questionnaires. Sites may elect not to contact patients and not collect the prospective questionnaire.

Clinical variables will include demographic data, cardiac risk factors, medications and details of presentation (including peak troponin, left ventricular ejection fraction (LVEF), and days to discharge), as well as follow-up data, including recurrent events, and symptoms of depression, anxiety, stress, and PTSD.

Clinical data will be obtained by study collaborators and entered into a secure database maintained on Stanford systems. De-identified imaging data will be uploaded by collaborators. Imaging data will be analyzed by two independent readers (selected from participating institutions).

Study population

Participants with pregnancy-related and non pregnancy-related SCAD will be recruited from the population of SCAD patients known to an international collaborative of investigators. We expect to enroll approximately 400 patients, 100 of whom have experienced peripartum SCAD. For each enrolled participant with peripartum SCAD, we will enroll 3 patients with non-peripartum SCAD who are the closest match on age at SCAD event and country.

What researchers measure

Primary outcomes

  1. First Major Adverse Cardiovascular Event (post-SCAD)

    The time from the first SCAD event until the first occurrence of (1) myocardial infarction, (2) re-vascularization, (3) stroke, or (4) death due to cardiovascular cause.

    Time frame: First SCAD event represents t=0. Time (in days) from t=0 until the first occurrence of any of the above, for up to 6-months after t=0.

Secondary outcomes

  1. Depression

    Patient Health Questionnaire (PHQ9) is a 9-item questionnaire that measures depression on a scale of 0-27 (where \>20 is major depression).

    Time frame: At survey administration (post-SCAD), ranging from 6-months to 10 years post SCAD.

  2. Anxiety

    Generalized Anxiety Disorder (GAD-7) is a 7-item questionnaire that measures anxiety on a scale of 0-21 (where \>14 is severe anxiety).

    Time frame: At survey administration (post-SCAD), ranging from 6-months to 10 years post SCAD.

  3. Stress

    Perceived Stress Scale (PSS) is a 10-item questionnaire that measures stress on a scale of 0-40 (where \>26 is high perceived stress).

    Time frame: At survey administration (post-SCAD), ranging from 6-months to 10 years post SCAD.

  4. Post-Traumatic Stress Disorder

    PTSD CheckList (PCL-5) is a 20-item questionnaire that assesses the presence and severity of PTSD symptoms on a scale of 0-80 (where \>32 suggests the patients needs further assessment to confirm a diagnosis of PTSD).

    Time frame: At survey administration (post-SCAD), ranging from 6-months to 10 years post SCAD.

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 25, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
