Summary
Malnutrition markers in congestive heart failure (CHF) patients were assessed using GNRI, PNI, and CONUT scores. The CONUT and PNI scores were found to be the best indicators for malnutrition risk in CHF patients.
Area of Science:
- Clinical Nutrition
- Cardiology
- Biochemistry
Background:
- Congestive heart failure (CHF) significantly impacts patient quality of life and is linked to high morbidity and mortality.
- Malnutrition is prevalent in CHF patients, particularly in severe stages, increasing complication and mortality risks.
- Effective nutritional strategies require accurate malnutrition assessment tools for CHF management.
Purpose of the Study:
- To investigate the prevalence of malnutrition markers in a Georgian CHF population.
- To analyze the association between malnutrition indices and nutrient status.
- To determine the correlation of malnutrition markers with congestive heart failure.
Main Methods:
- 96 CHF patients (43 female, 53 male, average age 69.85) were enrolled.
- Nutritional screening utilized the Geriatric Nutritional Risk Index (GNRI), Prognostic Nutritional Index (PNI), and Controlling Nutritional Status (CONUT) score.
- Blood tests assessed acute phase reactants and protein-energy malnutrition markers.
Main Results:
- A significant negative correlation was observed between the CONUT and PNI scores.
- CONUT and PNI were identified as the most effective tools for assessing malnutrition risk in the study group.
- Prealbumin, lipid profile, and transferrin decreased with increasing CONUT and PNI risk scores, while Interleukin-6 increased.
Conclusions:
- CONUT and PNI are reliable indicators for assessing malnutrition in CHF patients.
- These nutritional indices correlate with specific biomarkers, aiding in risk stratification.
- Improved nutritional assessment can significantly impact CHF management and patient outcomes.

Additional therapies for treating patients with heart failure (HF) may include procedural interventions, supplemental oxygen, the management of sleep disorders, and nutritional therapy.Procedural InterventionsImplantable Cardioverter-Defibrillator: For patients at risk of life-threatening arrhythmias due to severe left ventricular dysfunction, an Implantable Cardioverter-Defibrillator (ICD) can detect and terminate these arrhythmias, preventing sudden cardiac death and improving survival rates.

The first step in nursing management of a patient with heart failure involves thoroughly assessing the patient's medical history.Subjective Data: Obtain the patient's medical history of coronary artery disease, hypertension, myocardial infarction, and symptoms like dyspnea, orthopnea, and paroxysmal nocturnal dyspnea.Objective Data: Conduct a physical examination to identify findings such as jugular vein distention, pulmonary crackles, tachycardia, murmurs, peripheral edema, and vital signs,...

Assessment: Nursing management of patients with cardiomyopathy begins with a thorough assessment of the patient's history, including a family history of cardiomyopathy or sudden cardiac death, personal history of heart disease, hypertension, diabetes, and any alcohol consumption or drug use.During the physical examination, assess vital signs, look for signs of heart failure (such as edema, jugular venous distention, and cyanosis), auscultate for abnormal heart sounds (like murmurs and gallops),...

Mitral regurgitation (MR) is a condition where the mitral valve does not close properly, leading to the backward flow of blood from the left ventricle into the left atrium during systole. This condition can arise from various causes, including rheumatic fever, infective endocarditis, or degenerative valve disease. Effective nursing management is crucial to optimizing patient outcomes and involves comprehensive assessment and targeted interventions.Comprehensive Patient AssessmentA detailed...

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

01:17Pathophysiology of Heart Failure
2.4K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...
