Assessment of Malnutrition in Heart Failure and Its Relationship with Clinical Problems in Brazilian Health Services

Sex-related differences in the impact of nutritional status on in-hospital mortality in heart failure: a retrospective cohort study

AIMS

A nutritional status is related to the length of hospitalization and in-hospital mortality of patients with heart failure (HF). The aim of this study is to assess the prognostic impact of nutritional status and body mass index (BMI) on in-hospital mortality among patients with HF relative to their sex.

METHODS AND RESULTS

We conducted a retrospective study and analysis of 809 medical records of patients admitted to the Institute of Heart Disease of the University Clinical Hospital in Wroclaw (Poland). Women were statistically significantly older than men (74.67 ± 11.15 vs. 66.76 ± 17.78; P < 0.001). In unadjusted model, significant predictors of the odds of in-hospital mortality for men were underweight (OR = 14.81, P = 0.001) and the risk of malnutrition (OR = 8.979, P < 0.001). In the case of women, none of the traits analysed was significant. In age-adjusted model, significant independent predictors of the odds of in-hospital mortality in the case of men were BMI < 18.5 (OR = 15.423, P = 0.001) and risk of malnutrition (OR = 5.557, P = 0.002). In the case of women, none of the nutritional status traits analysed were significant. In multivariable-adjusted model in men, significant independent predictors of the odds of in-hospital mortality were BMI < 18.5 (OR = 15.978, P = 0.007) compared with having normal body weight and the risk of malnutrition (OR = 4.686, P = 0.015). In the case of women, none of the nutritional status traits analysed were significant.

CONCLUSION

Both underweight and the risk of malnutrition are direct predictors of the odds of in-hospital mortality in men, but not in women. The study did not find a relationship between nutritional status and in-hospital mortality in women.

Malnutrition and infection lead to poor prognosis and heavy financial burden of patients with chronic heart failure

Background

Chronic heart failure (CHF) is a major public health concern, as it is associated with poor prognosis and heavy financial burden. In recent years, there has been increasing interest in medications for CHF in China, but few studies pay attention to the effects of nutrition and infection.

Methods and results

This was a retrospective study collected patients with CHF admitted to the Department of Cardiology of Qilu Hospital of Shandong University from January 2017 to May 2018. Patients were classified according to the prognosis and the financial burden. Through comparison and regression analysis, we found that the factor associated with worse prognosis were decreased heart rate, albumin and prealbumin; β-blockers and mineralocorticoid receptor antagonism (MRA) were the factor improved the prognosis of patients with CHF; the factor overburdening financial condition were infection, decreased prealbumin, high Alanine aminotransferase (ALT), usage of recombinant human brain natriuretic peptide (rhBNP) and Levosimendan; aspirin and Sacubitril/Valsartan were the factor releasing financial burden of patients with CHF. Then, we grouped by Controlling Nutritional Status (CONUT) score, which enabled evaluation of the patient's protein reserve and immune defenses. Patients in the malnutrition group had higher infection ratios, longer hospital stays, and greater hospital expenses than the normal group. The improvement ratios of therapeutic outcomes in the moderate or severe malnutrition group were lower than in the normal and mild malnutrition group.

Conclusion

Malnutrition and infection caused poor prognosis and increased financial burden of patients with CHF. The high CONUT score indicated the CHF patient's unfavorable prognosis and heavy financial burden.
