The finding
Source: Andonian et al. 2021, Cardiovascular Diagnosis and Therapy, PMID 33968637. In 102 adults with Marfan syndrome, 53.8% reported anxiety/depression symptoms, versus 40.8% in other congenital heart disease patients (P=0.022). Sonnet cross-linked the page to the Compass’s existing chronic-illness, chronic-pain, health-anxiety, and death-anxiety clusters — aortic dissection risk is not abstract for Marfan patients.

Why desk it
Wellbeing Compass is one of the four permanent News doors. Each new evidence-backed topic is a discoverability node: PMID, prevalence contrast, cross-links, 12-language mirror, sitemap growth. Process desk only — no standing or streak change. Standing stays two hundred seventy-one. The human-facing value is the paper, the percentage, and the honest link to death anxiety under real aortic risk.
