Trial Outcomes & Findings for MIcrovascular dysfuNction In Moderate-severe Psoriasis (NCT NCT04271540)

NCT ID: NCT04271540

Last Updated: 2025-11-25

Results Overview

Change (from baseline) in global CFR, as measured by PET imaging at 24 weeks after initiation of Tildrakizumab therapy. Coronary flow reserve (CFR), the ratio of peak vasodilator stress to rest myocardial blood flow (MBF), represents the maximal ability to augment coronary flow and myocardial perfusion. Absolute MBF was computed from the rest and stress myocardial perfusion PET images using commercially available software (Corridor4DM; Ann Arbor, Michigan) and a two-compartment tracer kinetic model. Impaired MBFR is defined as a ratio of \<2.0, which is associated with increased cardiovascular risk.
