Congestion can be treated with diuretics or continuous renal replacement therapy (CRRT). Aim of this study was to evaluate if diuretics and CRRT, used in agreement to international guidelines, may have a dissimilar decongestion ability in patients with decompensated HF with different baseline characteristics. Methods: In 88 patients with HF (NYHA class III-IV) we evaluated the effect of CRRT (n = 46) and intravenous diuretics (n = 42) on clinical and instrumental signs of congestion. A clinical score was obtained as the sum of signs and symptoms of HF to estimate the severity of each patient’s clinical condition. The choice of diuretics or CRRT was guided by renal impairment or diuretics’ resistance. Results: A significant reduction in clinical HF score was observed in the CRRT group at discharge vs admission (1.3 ± 1.9 vs 5.7 ± 2.3, P < 0.001) and in the diuretic group (1.8 ± 1.4 vs 3.7 ± 1.6, P < 0.001), while a significant reduction in radiographic signs of pulmonary congestion, pleural effusion, echocardiographic systolic arterial pulmonary pressure (43.4 ± 13.6 vs 50.5 ± 20.2 mmHg, P < 0.005) and NT-proBNP (6,676 vs 15,492 pg/ml, P < 0.05) were observed only in CRRT patients. Moreover, also urine output significantly increased only in CRRT patients (1.8 ± 0.8 vs 0.9 ± 0.6 ml/h/kg, P < 0.001). Conclusions: CRRT and diuretics showed an equivalent ability in relieving clinical signs and symptoms of HF but only CRRT was able to significantly improve several instrumental and biohumoral indicators of congestion. |
