Usefulness of Geriatric Nutritional Risk Index for Assessing Nutritional Status and Its Prognostic Impact in Patients Aged ≥65 Years With Acute Heart Failure

Backgrounds: The Get with The Guidelines (GWTG) heart failure (HF) risk score was developed in the GWTG inpatient HF registry to predict in-hospital mortality and has been recently reported to be associated with post-discharge long-term outcomes. Malnutrition is associated with poor outcome in ADHF patients. However, there is no information available on the long-term prognostic significance of the combination of GWTG-HF risk score and malnutrition in patients admitted for ADHF, relating to reduced left ventricular ejection fraction (LVEF). Methods: We studied 303 ADHF patients discharged with survival (HFrEF(LVEF<40%); n=180, HFpEF(LVEF≥40%;n=123). At the admission, we evaluated GWTG-HF score and nutritional status. Variables required for the GWTG-HF risk score were race, age, systolic blood pressure, heart rate, serum levels of blood urea nitrogen and sodium, and the presence of chronic obstructive pulmonary disease. Nutritional status was evaluated by Geriatric Nutritional Risk Index (GNRI) calculated as follows: 14.89 · serum albumin (g/dl) + 41.7 · BMI/22, and malnutrition was defined as GNRI<92. The study endpoint was cardiovascular-renal poor outcome (CVR), defined as cardiovascular death and the development of end-stage renal disease requiring renal replacement therapy. Results: During a follow-up period of 4.2±3.3 yrs, 86 patients had CVR. At multivariate Cox analysis, GWTG-HF risk score and GNRI were significantly and independently associated with CVR, in both HFrEF and HFpEF groups. The patients with both greater GWTG-HF score (>median value=35) and malnutrition had a significantly increased risk of CVR than those with either and none of them ([HFrEF] 60% vs 32% vs 16%, p<0.0001, [HFpEF] 45% vs 18% vs 12%, p<0.0001, respectively) Conclusion: Malnutrition assessed by GNRI would provide the additional long-term prognostic information to GWTG-HF risk score in patients admitted for ADHF, irrespective of the presence of reduced LV function.

Nutritional Risk Index

Background: Limited data are available regarding change in the nutritional status after transcatheter aortic valve replacement (TAVR). This study evaluated the prognostic impact of the change in the geriatric nutritional risk index following TAVR. Methods: TAVR patients were analyzed in a prospective and observational study. To analyze the change in nutritional status, geriatric nutritional risk index of the patients was calculated on the day of TAVR and at 3-month follow-up. The impact of the change in nutritional risk index after TAVR on all-cause mortality, heart failure hospitalization (HF-h), and the composite of all-cause death and HF hospitalization was analyzed using the Cox Proportional Hazards model. Results: Four hundred thirty-three patients were included. After TAVR, 68.4% (n=182) patients with baseline nutritional risk improved compared with 31.6% (n=84) who remained at nutritional risk. The change from no-nutritional risk to nutritional risk after TAVR occurred in 15.0% (n=25), while 85.0% (n=142) remained without risk of malnutrition. During follow-up, 157 (36.3%) patients died and 172 patients (39.7%) were hospitalized due to HF. Patients who continued to be at nutritional risk had a higher risk of mortality (hazard ratio [HR], 2.10 [95% CI, 1.30–3.39], P =0.002), HF-h (HR, 1.97 [95% CI, 1.26–3.06], P =0.000), and the composite of death and HF-h (HR, 2.0 [95% CI, 1.37–2.91], P <0.001). The change to non-nutritional risk after TAVR significantly impacted mortality (HR, 0.48 [95% CI, 0.30–0.78], P =0.003), HF-h (HR, 0.50 [95% CI, 0.34–0.74], P =0.001), and the composite outcome (HR, 0.44 [95% CI, 0.32–0.62], P <0.001). Conclusions: Remaining at nutritional risk after TAVR confers a poor prognosis and is associated with an increased risk of mortality and HF-h, while the change from risk of malnutrition to non-nutritional risk after TAVR was associated with a halving of the risk of mortality and HF-h. Further studies are needed to identify whether patients at nutritional risk would benefit from nutritional intervention during processes of care of TAVR programs.

The Mean

Aims: Malnutrition in elderly patients is one of the important issues in an aging society. We aimed to investigate the prevalence and prognostic impact of malnutrition assessed using the geriatric nutritional risk index in very elderly patients hospitalized owing to heart failure. Methods: We enrolled 213 consecutive patients aged ⩾80 years who were hospitalized with heart failure. The mean age was 87.2 ± 4.9 years, and 43.7% of them were male. The nutritional status on admission was evaluated using the geriatric nutritional risk index, which was calculated as follows: 14.89 × serum albumin (g/dL) + 41.7 × body mass index/22. The patients were divided into two groups, a low geriatric nutritional risk index group (<92) with malnutrition risk and a high geriatric nutritional risk index group (⩾92) without malnutrition risk. Results: The mean geriatric nutritional risk index of all patients was 90.7 ± 10.6, and 108 patients (50.7%) had low geriatric nutritional risk index. During the 540-day follow-up, the all-cause mortality was significantly higher in the low geriatric nutritional risk index group than in the high geriatric nutritional risk index group (35.7% vs. 12.9%, p < 0.001). The Cox proportional-hazards regression analysis revealed that low geriatric nutritional risk index was an independent predictor of mortality (hazard ratio, 2.28; 95% confidence interval, 1.15–4.49; p = 0.02). Conclusions: Low geriatric nutritional risk index on admission was common and was associated with poor prognosis in patients aged ⩾80 years who were hospitalized owing to heart failure.
