ABSTRACT
Antecedentes El aumento de la presión intraabdominal (PIA) se ha correlacionado con elevación de la creatinina en pacientes con insuficiencia cardíaca con fracción de eyección ventricular izquierda gravemente deprimida (ICFEr). Sin embargo, dicha variable no se ha explorado en pacientes más estables o con insuficiencia cardíaca y fracción de eyección preservada (ICFEp). Pacientes y método Estudio observacional, prospectivo y descriptivo consistente en la medición de la PIA en pacientes ingresados por insuficiencia cardíaca (IC) descompensada. Se estratificó la muestra según la fracción de eyección ventricular izquierda (FEVI) con un punto de corte del 50%, con el objetivo de analizar la PIA, así como las características basales y el grado de congestión empleando la ecografía clínica y la impedanciometría. Resultados Se incluyeron un total de 56 pacientes, 22 con ICFEr y 34 con ICFEp. Los pacientes con ICFEr presentaron una mayor prevalencia de cardiopatía isquémica (11 vs. 6; p = 0,010) y EPOC/asma (6 vs. 2%; p = 0,025). La PIA fue más alta en pacientes con ICFEr (17,2 mmHg vs. 13,3 mmHg; p = 0,004), sin diferencias en la función renal al ingreso según la FEVI (CKD-EPI creatinina) (ICFEr 55,0 mL/min/1,73 m2 [32,6-83,6] vs. ICFEp 55,0 mL/min/1,73 m2 [44,0-74,9]; p = 0,485). Los pacientes con ICFEr presentaron un perfil más congestivo estimado por ecografía (colapso de la cava inferior [26% vs. 50%; p = 0,001]), impedanciometría (agua corporal total al ingreso: 46 L vs. 41 L; p = 0,052 y a las 72 horas 50,2 L vs. 39,1 L; p = 0,038) y concentración de CA125 (68 U/mL vs. 39 U/mL; p = 0,037). Conclusiones Durante los episodios de descompensación los pacientes con ICFEr tienen mayor elevación de la PIA y un mayor grado de congestión sistémica (AU)
Background The increase in intraabdominal pressure (IAP) has been correlated with increased creatinine levels in patients with heart failure with severely reduced left ventricular ejection fraction (HFrEF). However, IAP has not been examined in more stable patients or those with heart failure with preserved ejection fraction (HFpEF). Patients and method We conducted an observational, prospective descriptive study that measured the IAP of patients hospitalised for decompensated heart failure (HF). The sample was stratified according to left ventricular ejection fraction (LVEF), with a cut-off of 50%. The objective was to analyse the IAP, the baseline characteristics and degree of congestion using clinical ultrasonography and impedance audiometry. Results The study included 56 patients, 22 with HFrEF and 34 with HFpEF. The patients with HFrEF presented a higher prevalence of ischaemic heart disease (11% vs. 6%; p = 0.010) and chronic obstructive pulmonary disease/asthma (6% vs. 2%; p = 0.025). The IAP was higher in the patients with HFrEF (17.2 vs. 13.3 mmHg; p = 0.004), with no differences in renal function at admission according to the LVEF (CKD-EPI creatinine) (HFrEF 55.0 mL/min/1.73 m2 [32.6-83.6] vs. HFpEF 55.0 mL/min/1.73 m2 [44.0-74.9]; p = 0.485). The patients with HFrEF presented a more congestive profile determined through ultrasonography (inferior vena cava collapse [26% vs. 50%; p = 0.001]), impedance audiometry (total body water at admission, 46 L vs. 41 L; p = 0.052; and at 72 h, 50.2 L vs. 39.1 L; p = 0.038) and CA125 concentration (68 U/mL vs. 39 U/mL; p = 0.037). Conclusions During the decompensation episodes, the patients with HFrEF had a greater increase in IAP and a higher degree of systemic congestion (AU)

ABSTRACT
BACKGROUND: An increase in intraabdominal pressure (IAP) during acute heart failure, seems to be directly related to worsening renal function, which leads to worse clinical outcomes. We aimed to analyze the relationship between IAP and determinants of renal function during admission for acute decompensation of heart failure (ADHF) in a conventional Internal Medicine Ward. PATIENTS AND METHODS: Descriptive and prospective study. Patients admitted for ADHF with an estimated glomerular filtration rate > 30mL/min/1.73 m2, willing to participate and who gave their informed consent were included. Ethics Committee of Aragon approved the protocol (PI 15 0227). RESULTS: We hereby report the results of an interim analysis of the first 28 patients included. Patients were divided in 2groups according to the median of IAP measured during the first 24h after admission for ADHF, namely high IAP (IAP>15mmHg) and low (IAP< 15mmHg). Fourteen patients were included in each group. No differences were found in baseline clinical characteristics, comorbidities or treatment between both groups. Patients with IAP above 15mmHg, showed a significant lower baseline estimated glomerular filtration rate (70.7 vs. 44.4mL/min/1.73 m2 with p=0.004], blood urea 36 vs. 83mg/dL with p=0.002]; serum creatinine 0.87 vs. 1.3mg/dL with p=0.004 and cystatin C 1.2 vs. 1.94mg/dL with p= 0.002. Additionally, these patients had higher uric acid (5.7 vs. 8.0, p=0.046), lower hemoglobin concentrations (11.7 vs. 10.5g/L, p=0.04) and longer length of hospital stay (6.5 vs. 9.6 days, p=0.017). CONCLUSIONS: The increase in IAP seems to be a frequent finding in patients admitted for ADHF. Patients share similar clinical profile irrespective of IAP, although the increase in IAP is associated with a significant baseline impairment of renal function.
