What this trial studies

SCAPIS 2 Spectrum is a prospective observational sub-study enrolling about 900 SCAPIS participants aged 60–75 across five high‑risk arms (obstructive CAD, ANOCA, metabolic syndrome with diabetes, left ventricular systolic dysfunction, and left ventricular diastolic dysfunction). The study applies three investigational dermal perfusion devices — Perimed Periflux 6000 EPOS (DRS + LDF), PeriCam MultiFlow (MELSCI + MSI), and the TCI P4 (spatial frequency domain imaging) — combined with functional provocations such as post‑occlusive reactive hyperemia, flow‑motion analysis, and thermal provocation. Cardiac microvascular function is measured using adenosine stress cardiac magnetic resonance with first‑pass perfusion and quantitative myocardial blood flow to derive myocardial perfusion reserve. The goal is to link skin microcirculation signals with cardiac microvascular metrics to identify subclinical systemic microvascular dysfunction.

Who should consider this trial

Good fit: Ideal candidates are SCAPIS participants aged 60–75 who were invited to SCAPIS2, meet one of the five specified high‑risk cohort definitions, and can undergo skin imaging and adenosine stress CMR.

Not a fit: Patients with skin scarring, tattoos, or amputations that prevent device measurements, or those who cannot undergo CMR (for example due to incompatible implants, contrast/adenosine contraindications, or severe claustrophobia), are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, these non-invasive tests could detect early microvascular dysfunction and enable earlier interventions to prevent progression to overt cardiovascular disease.

How similar studies have performed: Previous research using non-invasive microvascular imaging and CMR perfusion has shown promise in detecting microvascular abnormalities, but the combined multi-device approach remains relatively novel and not yet established for routine clinical use.
