Saito A, Amiya E, Hatano M, et al. - Researchers examined the prognostic value of the Controlling Nutritional Status (CONUT) score (range 0–12, including serum albumin, total cholesterol, and lymphocytes) for patients undergoing left ventricular assist device (LVAD) implantation. Using the preoperative CONUT score, they categorized 63 consecutive patients who underwent the continuous-flow LVAD implantation into two groups: lower CONUT score (0–4: normal to mild malnutrition) and higher CONUT score (5–12: moderate to severe malnutrition). The higher CONUT group is characterized by a significantly higher mean right atrial pressure (10.9 ± 4.7 vs 7.3 ± 4.1 mmHg), a significantly higher mortality rate (25% vs 2.6%) and significantly more bleeding events. The preoperative CONUT score may indicate systemic venous congestion and offer a valuable prognostic index of clinical sequences after LVAD implantation.
