Investigation of cystatin C and cystatin C based estimated glomerular filtration rate in pregnant patients with heart failure

Impaired cardiac function leads to impaired renal function. We assessed renal function in pregnant patients with heart failure. This was a retrospective study. From 1999 to 2010, 42 pregnant patients with heart failure were classified into the single-pregnancy group and the twin or multifetation group. Clinical manifestations were assessed. Serum concentrations of creatinine and cystatin C were assessed. Estimated glomerular filtration rate (eGFR) based on serum concentrations of creatinine or cystatin C was completed. There were 29 single pregnancies, 12 twin pregnancies, and one multifetation. Ten patients in the twin pregnancy or multifetation group had in-vitro fertilization. The concentration of creatinine was 84.6±33.8 μmol/L and the creatinine-based eGFR was 87.2±34.9 mL/min per 1.73 m . The percentage of patients with a creatinine based eGFR
