Serum creatinine is an important by product produced by non-enzymatic degradation of muscle creatine and it is filtered out of the blood by the kidneys. The level of serum creatinine is maintained by the balance between its generation and excretion. Serum creatinine concentration in cardiac patients serves as a marker of renal damage. Glycated haemoglobin (HbA1c) represents a reliable average of blood glucose over preceding three months. Studies have proposed that the association of HbA1c with cardiovascular risk may be partially mediated by the development of hypertension. Therefore, this...
