Peroxiredoxin-4, a Marker of Systemic Oxidative Stress, is Associated with Incident Heart Failure
Main finding · Incident HFResult — go to the resultHazard ratio per 1 SD increase in log-Prx4 1.22 95% CI 1.09–1.36Authors' conclusion
Circulating Prx4 associates with the risk of developing HF, both with preserved and reduced ejection fraction.
