Urate predicts subsequent cardiac death in stroke survivors

Area of Science:

• Cardiology
• Neurology
• Metabolic Medicine

Background:

• Stroke survivors face increased risk of cardiac death.
• Conventional risk factors do not fully explain post-stroke cardiac mortality.
• The role of serum urate in predicting cardiac events after stroke requires further investigation.

Purpose of the Study:

• To determine if serum urate predicts cardiac death in stroke survivors.
• To assess urate's predictive value independent of atherosclerosis risk factors, creatinine, and diuretic use.

Main Methods:

• Serum urate concentration was measured in 354 unselected stroke survivors.
• Patients were followed for a median of 2.8 years, with cardiac death as the primary endpoint.
• Statistical analysis adjusted for conventional risk factors, renal function, and diuretic use.

Main Results:

• Elevated serum urate was associated with a threefold increased relative risk of cardiac death.
• In non-diuretic users, raised urate showed a 12-fold increased relative risk of cardiac death.
• Specific urate concentrations demonstrated high sensitivity and specificity for predicting 5-year cardiac death post-stroke.

Conclusions:

• Elevated serum urate concentration can stratify risk for future cardiac death after stroke.
• This predictive value holds true even for stroke survivors not using diuretic therapy.
• Serum urate may serve as a valuable biomarker for cardiac risk assessment in post-stroke patients.
