Study Links Covid Infection to Accelerated Vascular Ageing

Cardiologists caution that observational findings fall short of proving causality, calling for targeted research into underlying mechanisms.

Eine neue wissenschaftliche Studie zeigt, dass Covid-Infektionen zu einer Versteifung der Blutgefäße führen können.

Overview

  • The European Heart Journal published a cohort study of 2,390 participants from 16 countries measuring carotid-to-femoral pulse-wave velocity at six and 12 months post-Covid infection to estimate vascular ageing.
  • Infected individuals exhibited greater arterial stiffness compared with uninfected controls, with the effect most pronounced in women and Long Covid patients.
  • Vaccinated participants showed lower increases in vascular ageing indicators than their unvaccinated counterparts.
  • Patients treated in intensive care units experienced a marked reversal of arterial stiffness by the 12-month follow-up, suggesting that hospitalization or critical-care factors may influence long-term recovery.
  • Experts highlighted concerns about residual confounding and survival bias among male participants and urged replication studies with careful subgroup analyses before altering clinical guidance.
