ABSTRACT
Cardiogenic shock (CS) is characterized by the presence of a state of tissue hypoperfusion secondary to ventricular dysfunction. Hemodynamic monitoring allows us to obtain information about cardiovascular pathophysiology that will help us make the diagnosis and guide therapy in CS situations. The most used monitoring system in CS is the pulmonary artery catheter since it provides key hemodynamic variables in CS, such as cardiac output, pulmonary artery pressure, and pulmonary artery occlusion pressure. On the other hand, echocardiography makes it possible to obtain, at the bedside, anatomical and hemodynamic data that complement the information obtained through continuous monitoring devices. CS monitoring can be considered multimodal and integrative by including hemodynamic, metabolic, and echocardiographic parameters that allow describing the characteristics of CS and guiding therapeutic interventions during hemodynamic resuscitation.
ABSTRACT
ABSTRACT The desperate attempt to improve mortality, morbidity, quality of life and patient-reported outcomes in patients on hemodialysis has led to multiple attempts to improve the different modes, frequencies, and durations of dialysis sessions in the last few decades. Nothing has been more appealing than the combination of diffusion and convection in the form of hemodiafiltration. Despite the concrete evidence of better clearance of middle weight molecules and better hemodynamic stability, tangible evidence to support the universal adoption is still at a distance. Survival benefits seen in selected groups who are likely to tolerate hemodiafiltration with better vascular access and with lower comorbid burden, need to be extended to real life dialysis patients who are older than the population studied and have significantly higher comorbid burden. Technical demands of initiation hemodiafiltration, the associated costs, and the incremental benefits targeted, along with patient-reported outcomes, need to be explored further before recommending hemodiafiltration as the mode of choice.
RESUMO A tentativa desesperada de melhorar a mortalidade, morbidade, qualidade de vida e desfechos relatados pelos pacientes em indivíduos em hemodiálise levou a diversas tentativas de aprimorar os diferentes modos, frequências e durações das sessões de diálise nas últimas décadas. Nada foi mais atrativo do que a combinação de difusão e convecção na forma de hemodiafiltração. Apesar das evidências concretas de melhor depuração de moléculas de peso médio e melhor estabilidade hemodinâmica, evidências tangíveis para apoiar a adoção universal ainda estão distantes. Os benefícios de sobrevida observados em grupos selecionados que provavelmente toleram a hemodiafiltração com melhor acesso vascular e com menor carga de comorbidades precisam ser estendidos aos pacientes reais em diálise, que são mais velhos do que a população estudada e apresentam uma carga de comorbidades significativamente maior. As exigências técnicas do início da hemodiafiltração, os custos associados e os benefícios incrementais almejados, juntamente com os desfechos relatados pelos pacientes, precisam ser melhor explorados antes de se recomendar a hemodiafiltração como o modo de escolha.
ABSTRACT
Evaluation and staging of liver disease is essential in the clinical decision-making process of liver tumors. The severity of portal hypertension (PH) is the main prognostic factor in advanced liver disease. Performing an accurate hepatic venous pressure gradient (HVPG) measurement is not always possible, especially when veno-venous communications are present. In those complex cases, a refinement in HVPG measurement with a thorough evaluation of each of the components of PH is mandatory. We aimed at describing how some technical modifications and complementary procedures may contribute to an accurate and complete clinical evaluation to improve therapeutic decisions.

Objetivo Avaliar efeitos da suplementação de vitamina D3 sobre parâmetros hemodinâmicos centrais e atividade autonômica em indivíduos obesos/sobrepeso e baixos níveis de vitamina D (<30ng/dl). Métodos Ensaio clínico prospectivo, randomizado, duplo-cego (NCT 05689632), adultos 40-65 anos com índice de massa corporal ≥25<40 kg/m2. Hemodinâmica central avaliada por método oscilométrico (Mobil-O-Graph®), variabilidade da frequência cardíaca utilizando frequencímetro Polar (software Kubios®). Os pacientes (n=53) receberam placebo no grupo controle (CO, n=25) ou vitamina D3 (VD, n=28) 7000 UI/dia, avaliados antes (S0) e após 8 semanas (S8) com nível de significância de 0,05. Resultados Os grupos foram homogêneos na idade (51±6 vs. 52±6 anos, p=0,509) e níveis de vitamina D (22,8±4,9 vs. 21,7±4,5ng/ml, p=0,590). Na S8, o grupo VD apresentou níveis significativamente maiores de vitamina D (22,5 vs. 35,6ng/ml, p<0,001). Apenas o grupo VD mostrou redução significativa da pressão arterial sistólica (PAS; 123±15 vs. 119±14mmHg, p=0,019) e fosfatase alcalina (213±55 vs. 202±55mg/dl, p=0,012). O grupo CO mostrou elevação da pressão de aumento (AP: 9 vs. 12mmHg, p=0,028) e do índice de incremento (Aix: 26 vs. 35%, p=0,020), o que não foi observado no grupo VD (AP: 8 vs. 8mmHg, Aix: 26 vs. 25%, p>0,05). Grupo VD apresentou aumento no índice do sistema nervoso (iSN) parassimpático (-0,64±0,94 vs. -0,16±1,10, p=0,028) e no intervalo R-R (866±138 vs. 924±161ms, p=0,026). Conclusão Nesta amostra, a suplementação diária de vitamina D durante oito semanas resultou em melhora dos níveis pressóricos, parâmetros hemodinâmicos centrais e do equilíbrio autonômico.
Abstract Background Previous studies have been inconsistent in demonstrating beneficial cardiovascular effects of vitamin D supplementation. Objective To evaluate the effects of vitamin D3 supplementation on central hemodynamic parameters and autonomic activity in obese/overweight individuals with low vitamin D levels (<30ng/dl). Methods Adults 40-65 years old with body mass index ≥25<40 kg/m2 were enrolled in this prospective, randomized, double-blind clinical trial (NCT 05689632). Central hemodynamics was assessed using the oscillometric method (Mobil-O-Graph®), and heart rate variability using a Polar heart rate monitor (Kubios® software). Patients (n=53) received a placebo in the control group (CO, n=25) or vitamin D3 (VD, n=28) 7000 IU/day, and were evaluated before (W0) and after 8 weeks (W8) with a significance level of 0.05. Results The groups were homogeneous regarding age (51±6 vs 52±6 years, p=0.509) and vitamin D levels (22.8±4.9 vs 21.7±4.5ng/ml, p=0.590). At W8, the VD group had significantly higher levels of vitamin D (22.5 vs 35.6ng/ml, p<0.001). Only the VD group showed a significant reduction in systolic blood pressure (SBP; 123±15 vs 119±14mmHg, p=0.019) and alkaline phosphatase (213±55 vs 202±55mg/dl, p=0.012). The CO group showed an increase in augmentation pressure (AP: 9 vs 12 mmHg, p=0.028) and augmentation index (AIx: 26 vs 35%, p=0.020), which was not observed in the VD group (AP: 8 vs 8 mmHg, AIx: 26 vs 25%, p>0.05). VD group showed an increase in the parasympathetic nervous system index (PNSi) (-0.64±0.94 vs -0.16±1.10, p=0.028) and the R-R interval (866±138 vs 924±161 ms, p= 0.026). Conclusion In this sample, eight weeks of daily vitamin D supplementation resulted in an improvement in blood pressure levels and autonomic balance.

Resumo Fundamento O Teste de Caminhada de seis Minutos (TC6M) é comumente usado para avaliar pacientes com insuficiência cardíaca. No entanto, vários fatores clínicos podem influenciar a distância percorrida pelos pacientes no teste. A cardiografia de impedância (CI) na avaliação morfológica é uma ferramenta útil para avaliar a hemodinâmica cardíaca de maneira não invasiva. Objetivo Este estudo teve como objetivo comparar as respostas de aceleração e desaceleração do Débito Cardíaco (DC), da Frequência Cardíaca (FC), e do Volume Sistólico (VS) ao TC6M de indivíduos com insuficiência cardíaca e fração de ejeção reduzida (ICFEr) com as de controles sadios. Métodos Este é um estudo transversal observacional. O DC, a FC, o VS e o Índice Cardíaco (IC) foram avaliados antes, durante e após o TC6M por CI. O nível de significância adotado na análise estatística foi 5%. Resultados Foram incluídos 27 participantes (13 com ICFEr e 14 controles sadios). A aceleração do DC e da FC foi significativamente diferente entre os grupos (p<0,01 e p=0,039, respectivamente). Encontramos diferenças significativas no VS, no DC e no IC entre os grupos (p<0,01). A regressão linear mostrou uma contribuição deficiente do VS à mudança no DC no grupo com ICFEr (22,9% versus 57,4%). Conclusão O principal resultado deste estudo foi o fato de que indivíduos com ICFEr apresentaram valores mais baixos de aceleração do DC e da FC durante o teste de exercício submáximo em comparação a controles sadios. Isso pode indicar um desequilíbrio na resposta autonômica ao exercício nessa condição.
Abstract Background The six-minute walk test (6MWT) is commonly used to evaluate heart failure (HF) patients. However, several clinical factors can influence the distance walked in the test. Signal-morphology impedance cardiography (SM-ICG) is a useful tool to noninvasively assess hemodynamics. Objective This study aimed to compare cardiac output (CO), heart rate (HR), and stroke volume (SV) acceleration and deceleration responses to 6MWT in individuals with HF and reduced ejection fraction (HFrEF) and healthy controls. Methods This is a cross-sectional observational study. CO, HR, SV and cardiac index (CI) were evaluated before, during, and after the 6MWT assessed by SM-ICG. The level of significance adopted in the statistical analysis was 5%. Results Twenty-seven participants were included (13 HFrEF and 14 healthy controls). CO and HR acceleration significantly differed between groups (p<0.01; p=0.039, respectively). We found significant differences in SV, CO and CI between groups (p<0.01). Linear regression showed an impaired SV contribution to CO change in HFrEF group (22.9% versus 57.4%). Conclusion The main finding of the study was that individuals with HFrEF showed lower CO and HR acceleration values during the submaximal exercise test compared to healthy controls. This may indicate an imbalance in the autonomic response to exercise in this condition.
ABSTRACT
Introducción y objetivos: Se presenta el informe de actividad del año 2022 de la Asociación de Cardiología Intervencionista de la Sociedad Española de Cardiología (ACI-SEC). Métodos: Se invitó a todos los laboratorios de hemodinámica a participar en el registro. La recogida de datos se realizó a través de un cuestionario telemático. Una empresa externa realizó el análisis de datos, revisados por la junta directiva de la ACI-SEC. Resultados: Participaron 111 centros. El número de estudios diagnósticos aumentó un 4,8% con respecto a 2021, y el número de intervenciones coronarias percutáneas (ICP) se mantuvo estable. Las ICP sobre tronco coronario izquierdo aumentaron un 22%. El abordaje radial sigue siendo preferencial para las ICP (94,9%) y se observa un incremento de uso del balón farmacoactivo. El uso de técnicas de imagen intracoronaria se ha incrementado y se utilizan en el 14,7% de las ICP. También aumenta el uso de guía de presión (el 6,3% con respecto a 2021) y técnicas de modificación de placa. Sigue creciendo la ICP primaria, el tratamiento más frecuente (97%) en el infarto agudo de miocardio con elevación del segmento ST. La mayoría de los procedimientos no coronarios mantienen su tendencia creciente; destacan los implantes percutáneos de válvula aórtica, el cierre de orejuela, la técnica borde-a-borde mitral/tricuspídea, la denervación renal y el tratamiento de la enfermedad de la arteria pulmonar. Conclusiones: El Registro español de hemodinámica y cardiología intervencionista de 2022 demuestra un incremento en la complejidad de la enfermedad coronaria y un crecimiento notable de los procedimientos en cardiopatía estructural valvular y no valvular.(AU)
Introduction and objectives: This article presents the annual activity report of the Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC) for the year 2022. Methods: All Spanish centers with catheterization laboratories were invited to participate. Data were collected online and were analyzed by an external company in collaboration with the members of the board of the ACI-SEC. Results: A total of 111 centers participated. The number of diagnostic studies increased by 4.8% compared with 2021, while that of percutaneous coronary interventions (PCI) remained stable. PCIs on the left main coronary artery increased by 22%. The radial approach continued to be preferred for PCI (94.9%). There was an upsurge in the use of drug-eluting balloons, as well as in intracoronary imaging techniques, which were used in 14.7% of PCIs. The use of pressure wires also increased (6.3% vs 2021) as did plaque modification techniques. Primary PCI continued to grow and was the most frequent treatment (97%) in ST-segment elevation myocardial infarction. Most noncoronary procedures maintained their upward trend, particularly percutaneous aortic valve implantation, atrial appendage closure, mitral/tricuspid edge-to-edge therapy, renal denervation, and percutaneous treatment of pulmonary arterial disease. Conclusions: The Spanish cardiac catheterization and coronary intervention registry for 2022 reveals a rise in the complexity of coronary disease, along with a notable growth in procedures for valvular and nonvalvular structural heart disease.(AU)

SUMMARY: To observe the effect of sevoflurane combined with brachial plexus block (BPB) in children with humeral fracture surgery and its effect on hemodynamics. 84 children who received surgical treatment of humeral fracture in our hospital from September 2019 to September 2022 were selected. According to different anesthesia methods, the children were divided into control group and study group. The control group only received laryngeal mask sevoflurane; the study group received laryngeal mask sevoflurane combined with BPB. The operation situation, hemodynamic indexes, stress level, pain and adverse reactions of children was observed. The postoperative awakening time in the study group was lower than control group, the postoperative pain onset time in the study group was higher than control group (P0.05). Postoperative 2h, the levels of serum cortisol, b-endorpin, norepinephrine and epinephrine in the study group were lower than control group (P0.05). Sevoflurane combined with BPB is helpful to shorten the postoperative awakening time of children with humeral fracture, reduce the degree of postoperative pain, improve hemodynamics, and reduce stress response, and has good safety.

La exodoncia de los terceros molares inferiores es uno de los procedimientos clínicos más comunes en el cual el control del dolor mediante el bloqueo anestésico del nervio alveolar inferior, bucal y lingual resulta ser fundament al y la manera más común de hacerlo es mediante la infiltración de soluciones de anestesia local. Entre ellos la lidocaína y articaína son algunos de los más comunes y pueden estar asociado a vasoconstrictores como la epinefrina que puede provocar aumento de la presión arterial y frecuencia cardíaca razón por la cual se hace necesario la monitorización de cambios hemodinámicos durante la cirugía. Describir los cambios hemodinámicos asociados al uso de lidocaína al 2 % y/ o articaína al 4 % en la presión sistólica y diastólica, frecuencia cardiaca y saturación parcial de oxígeno en relación a distintos tiempos operatorios. Se realizó una revisión sistemática en las bases de datos de PubMed, SCOPUS, Web of Science y Sciencedirect. Se analizaron 7 ensayos clínicos controlados en los que utilizaron articaína al 4 % y/o lidocaína al 2 % con epinefrina al 1:100,000 y/o 1:200,000 en volúmenes de 1,8 a 5,4 mL, en los cuales evaluaron la presión sistólica y diastólica, frecuencia cardiaca y saturación parcial de oxígeno en distintos tiempos de la cirugía. Si bien hubo cambios en PAS, PAD, FC y SPO2, todas se mantuvieron dentro de rangos normales bajo el uso de articaína al 4 % y lidocaína al 2 % con epinefrina 1:100,000 y/o 1:200,000 a volúmenes de 1,8 a 5,4mL medidas a distintos tiempos operatorios.
The extraction of lower third molars is one of the most common clinical procedures in which pain control through anesthetic blockade of the lower alveolar, buccal and lingual nerves turns out to be essential and the most common way to do it is through the infiltration of solutions of local anesthesia. Among them, lidocaine and articaine are some of the most common and may be associated with vasoconstrictors such as epinephrine, which can cause an increase in blood pressure and heart rate, which is why it is necessary to monitor hemodynamic changes during surgery. To describe the hemodynamic changes associated with the use of 2 % lidocaine and/or 4 % articaine in systolic and diastolic pressure, heart rate and partial oxygen saturation in relation to different operative times. A systematic review was carried out in the PubMed, SCOPUS, Web of Science and Sciencedirect databases. Seven controlled clinical trials were analyzed in which 4 % articaine and/or 2 % lidocaine were used with epinephrine at 1:100,000 and/or 1:200,000 in volumes of 1,8 to 5,4 mL, in which systolic pressure was evaluated. and diastolic, heart rate and partial oxygen saturation at different times of surgery. Although there were changes in SBP, DBP, HR and SPO2, all remained within normal ranges under the use of 4 % articaine and 2 % lidocaine with epinephrine 1:100,000 and/or 1:200,000 at volumes of 1,8 to 5 .4mL measured at different operative times.

INTRODUCTION: Heart failure (HF) is among the leading causes of morbidity and mortality worldwide. Several conditions trigger left ventricular chronic pressure or volume overload, hypertrophy, systolic and diastolic dysfunction, leading to cardiac remodeling and a rapid progression toward HF. Therapeutic interventions elicit reverse remodeling (RR), a highly variable myocardial response that ranges from none to total ventricular structural/functional recovery. However, HF patients present several comorbidities and medications that mask a comprehensive molecular knowledge of RR and hinder the identification of potential biomarkers of its progression or prognosis. Therefore, instead of using this heterogeneous population or even animal models to understand myocardial remodeling, we propose studying pregnancy-induced cardiovascular remodeling and postpartum-induced RR. OBJECTIVES: To assess cardiovascular functional and structural adaptations during pregnancy and in postpartum, characterizing the associated molecular changes; as well as to explore the impact of hypertension, obesity and diabetes on these processes. METHODS: We will perform echocardiography and assess endothelial function and arterial stiffness (EndoPAT® and pulse wave velocity, respectively) and assess potential markers of remodeling and RR using plasma and urine samples from pregnant women. To translate to a HF context, we will determine the impact of risk factors (hypertension, obesity and diabetes) by studying subgroups of pregnant women with these comorbidities. RESULTS: Not applicable. CONCLUSION: We are convinced that understanding the impact of these comorbidities in such a homogeneous population, such as pregnant women, provides a valuable model to unveil the most relevant pathologic and often masked signaling pathways underlying cardiac remodeling and incomplete RR in a heterogeneous population, such as HF patients. Moreover, we expect to identify potential novel biomarkers of RR progression/prognosis more easily.

Objective We aimed to assess the usefulness of using the right ventricle outflow tract (RVOT) velocity-time integral (VTI) for echocardiographic monitoring of cardiac output compared to the gold standard, the VTI along the left ventricle outflow tract (LVOT). Design Prospective observational study. Setting A tertiary intensive care unit. Patients 100 consecutive patients. Interventions: echocardiographic monitoring in critically ill patients. Main variables of interest We used intraclass correlation coefficients (ICC) to compare echocardiographic measurements of LVOT VTI through apical window with RVOT VTI through the parasternal and modified subcostal windows and to assess interobserver reproducibility. Preplanned post hoc analyses compared the ICC between ventilated and nonventilated patients. Results At the time of echocardiography, 44 (44%) patients were mechanically ventilated and 28 (28%) were receiving vasoactive drugs. Good-quality measurements were obtained through the parasternal short-axis and/or apical views in 81 (81%) patients and in 100 (100%) patients through the subcostal window. Consistency with LVOT VTI was moderate for RVOT VTI measured from the modified subcostal view (ICC 0.727; 95%CI: 0.620.808) and for RVOT VTI measured from the transthoracic view (0.715; 95%CI: 0.590.807). Conclusions Measurements of RVOT VTI are moderately consistent with measurements of LVOT VTI. Adding the modified subcostal window allows monitoring RVOT VTI in all the patients of this selected cohort, even those under mechanical ventilation (AU)
Objetivo Valorar la utilidad de la integral velocidad-tiempo (IVT) del tracto de salida del ventrículo derecho (TSVD) para la monitorización del gasto cardíaco comparado con el gold standard, el IVT del tracto de salida del ventrículo izquierdo (TSVI). Diseño Estudio prospectivo observacional. Ámbito UCI de un hospital terciario. Paciente Cien pacientes consecutivos. Intervenciones Ecocardiografías realizadas para monitorización hemodinámica. Variables de interés principales Usamos el coeficiente de correlación intraclase (CCI) para comparar las mediciones de IVT TSVI a través de la ventana apical con el IVT TSVD a través de la ventana paraesternal y subcostal modificada y la reproducibilidad interobservador. Se planeó un análisis post hoc para comparar los resultados en pacientes ventilados con no ventilados. Resultados En el momento de la ecografía, 44 (44%) pacientes estaban en ventilación mecánica y 28 (28%) recibían fármacos vasoactivos. Mediciones de buena calidad se obtuvieron a través de la ventana paraesternal o apical en 81 (81%) pacientes, y en 100 (100%) con la ventana subcostal modificada. La consistencia del IVT TSVI fue moderada con el IVT TSVD medido con la ventana subcostal modificada (CCI 0,727; IC 95%: 0,62-0,808) y la transtorácica (0,715; IC 95%: 0,59-0,807). Conclusiones El IVT TSVD presenta una consistencia moderada cuando se compara con el IVT TSVI. Añadir la ventana subcostal modificada permite monitorizar el IVT TSVD en todos los pacientes de esta cohorte, incluso aquellos con ventilación mecánica (AU)
