“…A lower phase angle implies cell death or decreased cell integrity (34). With regard to HF, it has been described that bioimpedance phase angles are lower in patients with functional class NYHA III-IV compared with those with NYHA I-II (35). In agreement with our findings, a smaller phase angle after 6 months of follow-up was observed in HF patients who developed some alteration in the thyroid profile when compared with the rest of the cohort (36).…”

Background: Low plasma triiodothyronine (T 3 ) levels are considered a prognostic predictor of death in heart failure (HF) patients. Aim: To study an association between plasma T 3 levels and several cardiac, neurohormonal, and metabolic markers of HF. Methods: A total of 133 ambulatory HF patients (114 males; mean age 63.2 years) with left ventricular ejection fraction !40% were enrolled. TSH, total tetraiodothyronine (T 4 ) and T 3 , N-terminal pro-brain natriuretic peptide (NT-proBNP), and other cardiac and metabolic parameters were measured. The lowest tertile of T 3 (group 1) was compared against the two upper ones (group 2). Results: In simple logistic regression, the lowest T 3 tertile was associated with more advanced HF disease status: older (age: odds ratio (OR)Z1.05; confidence interval (CI) 95% 1.01-1.09, PZ0.004), lower functional capacity (walking test: ORZ0.996; CI 95% 0.993-0.999, PZ0.008), higher NT-proBNP (ORZ1.64; CI 95% 1.19-2.27, PZ0.003) and adiponectin levels (ORZ1.07; CI 95% 1.02-1.11, PZ0.004), lower DHEAS log-transformed (ORZ0.50; CI 95% 0.31-0.80, PZ0.004), and the presence of lower phase angle values as measured by body bioelectrical impedance analysis (ORZ3.18; CI 95% 1.50-6.71, PZ0.04) and worse renal function (ORZ0.96; CI 95% 0.94-0.98, PZ0.003). T 3 levels in the lowest tertile were independently associated with low phase angle values (ORZ2.95, CI 95% 1.16-7.50, PZ0.02) and the log transformation of DHEAS (ORZ0.56; CI 95% 0.32-0.97, PZ0.04). Conclusion: We have demonstrated an association between plasma T 3 levels in the lower range and other deranged hormonal and metabolic parameters in HF patients.

“…In previous research, we demonstrated an inverse association between fluid overload estimated by IBE and the NYHA functional class (12). IBE has also been validated as a tool capable of differentiating acute dyspnea due to heart failure in the Emergency Department, and an inverse correlation exists between IBE measurements and concentrations of the natriuretic peptide B (13).…”

ResumenIntroducción: los pacientes con insufi ciencia cardiaca (IC) desarrollan cambios importantes en la composición corporal; sin embargo, pocos estudios han evaluado prospectivamente la asociación entre estos cambios y el empeoramiento de la clase funcional en pacientes con IC crónica estable. Objetivo: el objetivo de este estudio fue evaluar si los cambios en los parámetros de la bioimpedancia estaban relacionados con el deterioro de la clase funcional de la clasifi cación de la New York Heart Association (NYHA) después de 6 meses. Métodos: se incluyeron 275 sujetos con IC crónica estable confi rmada por ecocardiograma. Se les realizaron mediciones de composición corporal por impedancia bioeléctrica de cuerpo completo con un equipo de múltiples frecuencias BodyStat QuadScan 4000 y se determinó la clase funcional por la clasifi cación de la New York Heart Association (NYHA) después de seis meses. Resultados: sesenta y seis (24%) sujetos mostraron deterioro de su clase funcional y 209 la mejoraron o no cambiaron. Se encontró mayor proporción de pacientes que cuya clase funcional se deterioró, en los que aumentó > 5% el agua extracelular y que desarrollaron hipervolemia de acuerdo a su localización en la gráfi ca resistencia/reactancia. La disminución de > 5% de la resistencia/talla se asoció de forma independiente con el deterioro de la clase funcional con un OR = 1.42 (IC 95% 1.01-2.0, p = 0.04). Conclusiones: la evaluación de la composición corporal a través de bioimpedancia eléctrica en pacientes con IC es un marcador de deterioro funcional. AbstractBackground: Heart failure (HF) patients develop important changes in body composition, but only a small number of studies have evaluated the associations between these changes and functional class deterioration in a prospective manner. Objective: The aim of this study was to evaluate whether changes in bioimpedance parameters were associated with NYHA functional class deterioration over six months. Methods: A total of 275 chronic stable HF patients confi rmed by echocardiography were recruited. Body composition measurements were obtained by whole body bioelectrical impedance with multiple frequency equipment (BodyStat QuadScan 4000). We evaluated functional class using the New York Heart Association (NYHA) classifi cation at baseline and after six months. Results: According to our results, 66 (24%) subjects exhibited functional class deterioration, while 209 improved or exhibited no change. A greater proportion of patients exhibited higher extracellular water (> 5%), and these patients developed hypervolemia, according to location on the resistance/reactance graph. A 5% decrease in resistance/height was associated with functional class deterioration with an OR of 1.42 (95% CI 1.01-2.0, p = 0.04). Conclusions: Body composition assessment through bioelectrical impedance exhibited a valuable performance as a marker of functional class deterioration in stable HF patients.

“…Vena Cava Index assessment: inferior vena cava diameter and collapse index. In patients with hyperhydration state due to heart failure, some authors showed as the reactance is strongly related with the BNP values and the NYHA functional classes 54 . Other authors found in critically ill patients a correlation between impedance and central venous pressure For the ED physicians, BIVA could represent the ideal hydration assessment technique because it measures fluids volume and concentration in real time, it has excellent precision, accuracy and reliability, it is portable, not invasive, inexpensive, safe and simple to use.…”
