Evaluation of Renal Function in Patients with Acute Heart Failure Through Dynamic Scintigraphy Examination. A pilot study

The Acute Decompensated Heart Failure National Registry (ADHERE) has shown that approximately 30% of patients hospitalized for acute heart failure exhibit acute or chronic renal insufficiency [1].The development of heart failure (HF) is often observed in patients with chronic kidney disease (CKD), and HF prevalence significantly increases in cohorts with declining GFR.The best diagnostic technique used to assess renal function through the administration of radiopharmaceuticals is renal scintigraphy.The results obtained through scintigraphy pertain to the total GFR, the contribution of individual kidneys to it, and changes in renography curves, all in the short term.From the clinical data obtained an increase in GFR values, there was a mean increase of 10.392 ml/min in GFR, following treatment with 1.4% hypertonic saline and furosemide.These results are certainly very encouraging although in a small patient group and require further investigation.Therapy with 1.4% hypertonic saline plus furosemide improves the clinical conditions and prognosis of patients with acute congestive heart failure associated with a deterioration in renal function and should be used in clinical practice.
