Abstract

Anemia is common in patients with chronic kidney disease (CKD) and contributes to cardiovascular alterations. Recent findings suggest that B-type natriuretic peptide (BNP) is a sensitive biomarker for left ventricular dysfunction, but relationship between hemoglobin and BNP in CKD patients is unclear. Hemoglobin, plasma BNP and serum creatinine levels were measured in 49 patients with CKD (without heart failure), divided in two groups according to the hemoglobin status (cut-off point 110 g/L). All patients underwent echocardiography in order to assess left ventricular (LV) morphology and function. The results showed that in the group of patients with hemoglobin levels under 110 g/L BNP levels were significantly elevated (p < 0.001), as well as left ventricular mass index (p < 0.001). Systolic and diastolic LV function were significantly better in patients with hemoglobin levels above 110 g/L (p < 0.001). Hemoglobin levels were inversely related to BNP values (r = -0.451, p < 0.001). Significantly negative correlation between BNP level and creatinine clearance (p = 0.009), and significantly positive correlation between BNP level and left ventricular mass index (LVMI) were established. A similar but positive relationship was obse...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
