Objective: To explore the correlation between uric acid (UA), cystatin C (Cys-C), homocysteine (Hcy), and chronic heart failure (CHF).
Methods: 45 patients with CHF were selected as the research group; 45 healthy people were selected as the control group. The levels of serum UA, Cys-C and Hcy were detected.
Results: The in The research group had much higher levels of serum UA, Cys-C and Hcy than the control group (all P<0.05). The levels of above indexes also increased with an increase in cardiac function classification. Patients with major adverse cardiovascular events (MACE) had much higher levels of serum UA, Cys-C, and Hcy than those without MACE in the research group (all P<0.05). In addition, the levels of these above indexes in the research group were all positively correlated with the left ventricular end diastolic diameter (LVEDD) (all P<0.05), and all negatively correlated with the f left ventricular ejection fraction (LVEF) (P<0.05). What is more, the levels of these above indexes in the research group were all positively correlated with New York Heart Association (NYHA) grade (all P<0.05). The diagnostic sensitivity of serum UA level, Cys-C level, and Hcy level in joint diagnosis of CHF patients was higher than that of any single index diagnosis (P<0.05), and the specificity of combined diagnosis was lower than that of single index diagnosis (P<0.05).
Conclusion: The levels of serum UA, Cys-C, and Hcy in CHF patients may be used as reference indexes for clinical screening of early CHF patients and could provide a certain reference for clinical evaluation.
