Plain English Summary

Background and study aims
Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial infarction with an increased incidence in young women, particularly in the period around giving birth. To date research into this condition in the UK and internationally has been very limited. We propose to undertake (i) detailed vascular phenotypingof an anticipated minimum of 280 patients with a history of SCAD (and matched controls) to determine if the coronary abnormality in SCAD is part of a wider arteriopathy and (ii) investigate whether predilection to SCAD is genetically-based.

Who can participate?
Patients with angiographically proven SCAD (confirmed by the study team) and healthy volunteers.

What does the study involve?
The study involves two elements. Firstly, a registry of patients who have had spontaneous coronary artery dissection and agree to provide access to their medical records, complete questionnaires and provided a blood sample for the research study. Secondly, some patients are invited for a clinical visit day when they undergo lots of different tests to try to understand in what ways their arteries are different from healthy people and to collect samples (blood and sometimes a skin biopsy) to advance laboratory research to understand the causes of SCAD.

What are the possible benefits and risks of participating?
The benefits are altruistic in terms of advancing our understanding of SCAD for the benefit of future patients with this condition. The risks relate only to the blood sampling and skin biopsy (in some patients) which can cause some local discomfort or bruising.

Where is the study run from?
Department of Cardiovascular Sciences, Glenfield Hospital, Leicester, UK

Study hypothesis1. SCAD is associated with remote arteriopathies demonstrable by non-invasive imaging (MRA) and measureable abnormalities of vascular elasticity, compliance and reactivity compared to age and sex-matched controls
2. SCAD has an identifiable genetic basis
Ethics approval(s)Approved 13/03/2014, NRES Committee East Midlands - Nottingham 1 (The Old Chapel, Royal Standard Place, Nottingham, NG1 6FS; 0115 8839695; NRESCommittee.EastMidlands-Nottingham1@nhs.net), ref: 14/EM/0056
ConditionSpontaneous coronary artery dissection
InterventionThe study has two elements.
The first is an observational registry. Consenting patients allow access to their medical information and clinical imaging at the time and following their Spontaneous Coronary Artery Dissection event and complete a detailed set of online questionnaires. They provide a blood sample for biobanking and DNA. Follow-up questionnaires are also provided annually.

The second element is a deep phenotyping study. Selected patients from the registry are invited to attend for a range of phenotyping investigations which may include: magnetic resonance imaging, magnetic resonance angiography, computed tomography coronary angiography, computed tomography angiography, vascular ultrasound, exercise testing, ambulatory ECG monitoring, retinal photography. A clinical assessment blood sample and skin biopsy sample may be taken.
Intervention typeOther
Primary outcome measure1. Presenting clinical data from index admission with Spontaneous Coronary Artery Dissection, review of patient notes and imaging, at baseline
2. Demographic, medical, obstetric, contraceptive and family history, review of patient notes, online (bespoke) questionnaires, patient interview, at time of registration
3. Coronary angiographic findings, patient imaging data, at baseline
4. MACCE, SCAD recurrence, pregnancy at follow-up, questionnaires clarified by patient interview if required, annually
Secondary outcome measures1. CMR assessment of myocardial function and infarct size, either from scans conducted on clinical grounds or research scans arranged as part of the phenotyping study
2. MRA/CTA assessment of remote arteriopathies either from scans conducted on clinical grounds or research scans arranged as part of the phenotyping study
3. USS assessment of arteries including FMD, IMT, luminal dimensions arranged as part of the phenotyping study
4. Cardiopulmonary exercise testing arranged as part of the phenotyping study
5. Ambulatory ECG monitoring conducted either on clinical grounds or arranged as part of the phenotyping study
6. Blood sampling for biomarkers and genetic studies
7. Skin biopsies for fibroblast culture for laboratory assays
