Is serum total p-cresylsulfate level associated with abnormal QTc interval in stable angina patients with early stage of renal failure?
This study indicates that serum total PCS levels are significantly higher in the presence of abnormal QTc interval and are associated with the QTc prolongation. Whether total PCS plays a role in the pathogenesis of QTc prolongation requires future investigation.
GFR and its estimations correlate with A1C. Although the relations between GFR and its estimations were not affected by the degree of glucose control, the precision and diagnostic accuracy of the CG formula were diminished for A1C >8%. The MDRD equation was more accurate and robust in diabetic patients with impaired renal function.
