Could Albuminuria Be an Overlooked Marker of Thrombotic Risk? – RPTH Journal
RPTH Journal shared a post on LinkedIn about a recent article by Xiu Hong Yang et al, adding:
”Could albuminuria be an overlooked marker of thrombotic risk?
We usually think of the urine albumin-to-creatinine ratio (UACR) as a kidney or cardiovascular marker.
But what if it also reflects systemic thrombotic vulnerability?
A new prospective RPTH study of 419,282 UK Biobank participants examined the relationship between albuminuria and future arterial thromboembolism (ATE) and pulmonary embolism (PE).
Here’s the key signal:
- Moderate albuminuria (UACR 3–30 mg/mmol) increased ATE risk
- Severe albuminuria (>30 mg/mmol) increased the risk of both ATE and c
- Risk intensified further with reduced kidney function or low serum albumin
What’s changing under the hood:
- Albuminuria reflects endothelial dysfunction and vascular injury
- Associated with platelet activation and hypercoagulability
- Linked to inflammatory pathways (CRP, VWF, ADAMTS13)
- Suggests a systemic prothrombotic state – not just kidney disease
(Figures 1–3 show dose-dependent increases in thrombotic risk with rising UACR)
Translation:
Albuminuria may not simply mark renal injury; it may identify patients with heightened endothelial and thrombotic dysfunction.
Big questions for the field:
- Should UACR be incorporated into thrombosis risk assessment?
- Is albuminuria a mediator of thrombosis – or a marker of systemic vascular injury?
- Could aggressive treatment of albuminuria reduce thromboembolic events?”
