Motivation: Iron deficiency anemia in chronic kidney disease (CKD) increases cardiovascular risk and mortality in peritoneal dialysis (PD) patients.
Goal(s): This study evaluated cardiac iron levels using CMR T2* sequences and assessed their predictive capacity for left ventricular dysfunction (LVSD) in PD patients with anemia.
Approach: Eighty-three end-stage renal disease (ESRD) patients and 41 controls were included. Standardized CMR imaging was used to analyze correlations between myocardial iron, hemoglobin, and LV function.
Results: Anemic patients had higher T2* values, indicating myocardial iron deficiency. This finding was associated with reduced left ventricular ejection fraction, highlighting its significance in LV dysfunction.
Impact: Cardiac magnetic resonance T2* mapping is a valuable technique for quantitatively measuring myocardial iron levels, facilitating earlier diagnosis of iron deficiency, and guiding treatment in peritoneal dialysis patients.
