Evaluation of vital signs through a mobile application in patients with heart failure: a opportunity for remote titration?

BACKGROUND: Virtual consultations have increased exponentially, but a limitation is the inability to assess vital signs (VS). This is particularly useful in patients with heart failure (HF) for titrating prognosis-modifying medication. This issue could potentially be addressed by a tool capable of measuring blood pressure (BP) and heart rate (HR) accurately, remotely, and conveniently. Mobile phones equipped with transdermal optical imaging technology could meet these requirements. OBJECTIVE: To evaluate the accuracy of a transdermal optical imaging-based app for estimating VS compared to clinical assessment in patients with HF. METHODS: A prospective cohort study included patients evaluated in an HF outpatient unit between February and April 2022. BP and HR were simultaneously assessed using the app and clinical examination (BP with an automated sphygmomanometer and HR by brachial palpation). Three measurements were taken by both the app and clinic for each patient, by two independent blinded physicians. RESULTS: Thirty patients were included, with 540 measurements of BP and HR. The mean age was 66 (± 13) years, 53.3% were male. The mean left ventricular ejection fraction was 37 ± 15, with 63.3% having previous hospitalizations for HF, and 63.4% in NYHA class II-III. The mean difference between the app measurement and its clinical reference measurement was 3.6 ± 0.5 mmHg for systolic BP (SBP), 0.9 ± -0.2 mmHg for diastolic BP (DBP), and 0.2 ± 0.4 bpm for HR. When averaging the paired mean differences for each patient, the mean across the 30 patients was 2 ± 6 mmHg for SBP, -0.14 ± 4.6 mmHg for DBP, and 0.23 ± 4 bpm for HR. CONCLUSION: The estimation of BP and HR by an app with transdermal optical imaging technology was comparable to non-invasive measurement in patients with HF and met the precision criteria for BP measurement in this preliminary study. The use of this new transdermal optical imaging technology provides promising data, which should be corroborated in larger cohorts.

ANTECEDENTES: Las consultas virtuales aumentaron exponencialmente, pero presentan como limitación la imposibilidad de valorar los signos vitales (SV), siendo especialmente útiles en los pacientes con insuficiencia cardiaca (IC) para titular medicación que modifica pronóstico. Este problema podría potencialmente solucionarse mediante una herramienta que pueda medir la presión arterial (PA) y frecuencia cardiaca (FC) de manera precisa, accesible y remota. Los teléfonos móviles equipados con tecnología de imágenes ópticas transdérmicas podrían cumplir con estos requisitos. OBJETIVO: Evaluar la precisión de una app basada en imagen óptica transdérmica para estimar SV en relación con la valoración clínica en pacientes con IC. MÉTODOS: Estudio de cohorte prospectivo, se incluyeron pacientes evaluados en una unidad ambulatoria de IC de febrero a abril del 2022. Se valoró simultáneamente la PA y FC mediante la app y el examen clínico (PA con un esfigmomanómetro automatizado y FC por palpación braquial). Se realizaron tres mediciones por app y clínica en cada paciente, por dos médicos independientes, encontrándose ciegos a los resultados. RESULTADOS: Se incluyeron 30 pacientes, con 540 mediciones de TA y de FC. Edad media de 66 (± 13) años, el 53.3% de sexo masculino. La fracción de eyección del ventrículo izquierdo media fue de 37 ± 15, con hospitalizaciones previas por IC el 63.3%, en CF II-III el 63.4%. La diferencia media entre la medición de la app y su medición de referencia clínica fue de 3.6 ± 0.5 mmHg para PA sistólica (PAS), 0.9 ± ­0.2 mmHg para PA diastólica (PAD) y 0.2 ± 0.4 lpm para FC. Cuando se promedian las diferencias medias emparejadas para cada paciente, la media entre los 30 pacientes es de 2 ± 6 mmHg para PAS, ­0.14 ± 4.6 mmHg para PAD y 0.23 ± 4 lpm para FC. CONCLUSIÓN: La estimación de PA y FC por una app con tecnología de imagen óptica transdérmica fue comparable a la medición no invasiva en pacientes con IC, y cumple los criterios de precisión de la medición de PA en este estudio preliminar. La utilización de esta nueva tecnología de imagen óptica transdérmica brinda datos prometedores, que deberán ser corroborados en cohortes de mayor tamaño.

RESUMEN Objetivos. Explorar la frecuencia e impacto de la violencia contra los trabajadores de salud de Argentina y compararlo con el resto de sus pares de Latinoamérica en el contexto de la pandemia por COVID-19. Materiales y métodos. Estudio de corte transversal a través de una encuesta electrónica al personal médico y no médico de Latinoamérica que desempeño tareas asistenciales desde marzo de 2020. Se utilizó una regresión de Poisson para estimar las Razones de Prevalencia crudas (RP) y ajustadas (RPa) con sus respectivos intervalos de confianza al 95%. Resultados. Un total de 3544 participantes de 19 países respondieron la encuesta; 1992 (56,0%) residían en Argentina. Entre los mismos, el 62,9% padeció al menos un hecho de violencia: 97,7% refirió violencia verbal y 11,8% violencia física. El 41,5% de los agredidos padecieron situaciones de violencia al menos una vez por semana. El personal de salud de Argentina vivenció más frecuentemente violencia que los de otros países (62,9% vs. 54,6%, p<0,001), siendo estos eventos más habituales y estresantes (p<0,05). Además, refirieron más frecuentemente haber considerado cambiar sus tareas asistenciales y/o deseos de abandonar su profesión (p<0,001). En la regresión de Poisson, los participantes de Argentina tuvieron una prevalencia de violencia mayor que los trabajadores de salud de la región (14,6%; p<0,001). Conclusiones. Existió una elevada prevalencia de violencia contra el personal de salud de Argentina durante la pandemia por COVID-19. Estos hechos tuvieron un alto impacto negativo entre quienes los padecieron. Nuestros datos sugieren que, esto podría haber sido más frecuente en Argentina respecto de otras regiones del continente.

ABSTRACT Objectives. To explore the frequency and impact of violence against healthcare workers in Argentina and to compare it with the rest of their Latin American peers during the COVID-19 pandemic. Materials and methods. A cross-sectional study was conducted by applying an electronic survey on Latin American medical and non-medical personnel who carried out health care tasks since March 2020. We used Poisson regression to estimate crude (PR) and adjusted (aPR) Prevalence Ratios with their respective 95% confidence intervals. Results. A total of 3544 participants from 19 countries answered the survey; 1992 (56.0%) resided in Argentina. Of these, 62.9% experienced at least one act of violence; 97.7% reported verbal violence and 11.8% physical violence. Of those who were assaulted, 41.5% experienced violence at least once a week. Health personnel from Argentina experienced violence more frequently than those from other countries (62.9% vs. 54.6%, p<0.001), and these events were more frequent and stressful (p<0.05). In addition, Argentinean health personnel reported having considered changing their healthcare tasks and/or desired to leave their profession more frequently (p<0.001). In the Poisson regression, we found that participants from Argentina had a higher prevalence of violence than health workers from the region (14.6%; p<0.001). Conclusions. There was a high prevalence of violence against health personnel in Argentina during the COVID-19 pandemic. These events had a strong negative impact on those who suffered them. Our data suggest that violence against health personnel may have been more frequent in Argentina than in other regions of the continent.

Telemonitoreo y sistema de alerta en tiempo real en insuficiencia cardiaca: estudio piloto de factibilidad, aceptabilidad y eficacia / Telemonitoring and a real-time alert system in heart failure: a preliminary pilot study of feasibility, acceptability and efficacy

Resumen Introducción: Existe creciente evidencia que el telemonitoreo (TM) de pacientes con insuficiencia cardíaca (IC) parece mejorar su evolución. No se han diseñado y evaluado plataformas de TM en Argentina. El objetivo fue evaluar la factibilidad, aceptabilidad, usabilidad y eficacia preliminar de una plataforma de TM de IC. Métodos: Se realizó un ensayo piloto apareado abierto, con un modelo de intervención de un solo grupo. Los pacientes con IC fueron incluidos en una consulta ambulatoria en enero de 2021. Se diseñó una pla taforma de TM las 24 h y 7 días de la semana. El punto final primario a 30 días fue la factibilidad, aceptabilidad y usabilidad. Resultados: Se incluyeron 20 pacientes, con una media de edad 62 ± 10 años. Se analizaron 542 cargas de parámetros. La autopercepción relacionada al estado de salud en comparación al inicio fue "levemente" o "marcadamente mejor" en el 60% de los pacientes, y en 75% "de acuerdo" o "totalmente de acuerdo" que el TM mejora el cuidado de la IC. En el 80% la carga diaria de parámetros no interfirió en su vida cotidiana. La media total de adherencia farmacológica previa a la intervención de TM fue de 6.8 ± 1.3 y posterior 7.7 ± 0,4 (p = 0.019), sin encontrar diferencias en las escalas de autocuidado. Conclusión: El TM de pacientes con IC parece ser factible, con un adecuado grado de aceptabilidad. Se observó un aumento significativo en la tasa de total adherencia, plantea una hipótesis de potencial beneficio a evaluar en una muestra mayor.

Abstract Introduction: There is growing evidence that telemonitoring (TM) in heart failure (HF) seems to improve their outcome. TM platforms have not been designed and evaluated in Argentina. The objective was to evaluate the feasibility, acceptability, usability and preliminary efficacy of a HF TM platform. Methods: An open-label, paired pilot trial was conducted with a single-group intervention model. HF patients were included in an outpatient clinic in January 2021. A 24-hour*7-day TM platform was designed. The primary endpoint at 30 days was feasibility, acceptability, and usability. Results: Twenty patients were included, mean age 62 ± 10 years; 542 parameter loads were analyzed. Self-perception related to health status compared to baseline was "slightly" or "markedly better" in 60% of patients, and in 75% "agree" or "totally agree" that TM improves patient care. In 80%, the load ing of parameters did not interfere with their daily activities. The total mean pharmacological adherence prior to the TM intervention was 6.8 ± 1.3 and 7.7 ± 0.4 afterward (p = 0.019), with no differences found in the self-care scales. Conclusion: The TM of patients with HF seems to be feasible, with an adequate degree of acceptability. A significant increase in the total adherence rate was reduced, raising a hypothesis of potential benefit to be evaluated in a larger sample.

Efecto de la vacunación contra la influenza en pacientes con enfermedad cardiovascular: un metaanálisis actualizado de ensayos clínicos controlados aleatorizados / Effect of Influenza Vaccination in Patients with Cardiovascular Disease: An Updated Meta- Analysis of Randomized Controlled Trials

RESUMEN Introducción : La influenza es una causa importante de morbilidad y mortalidad en pacientes con enfermedades cardiovasculares (ECV). El objetivo de esta revisión sistemática actualizada y metaanálisis fue evaluar los efectos de la vacunación contra la influenza (VI) sobre la mortalidad y morbilidad en pacientes adultos con ECV. Métodos : Se realizó una revisión sistemática y un metaanálisis (PubMed, Cochrane Library, International Clinical Trials Registry Platform, y búsqueda manual en presentaciones en congresos de la especialidad), de ensayos clínicos aleatorizados publicados hasta abril de 2022 que investigaron si la VI reduce la mortalidad por todas las causas en pacientes adultos con ECV, incluyendo insuficiencia cardíaca (IC) y enfermedad de las arterias coronarias (EAC), en comparación con pacientes que no fueron vacunados. Resultados : Se analizaron un total de seis ensayos clínicos, que incluyeron 9316 pacientes. Cinco ensayos incluyeron pacientes con EAC, y uno con IC. El seguimiento medio fue de 16 ± 9,7 meses. La VI se asoció con una reducción de la mortalidad en comparación con el control, cociente de riesgos (RR) 0,67, intervalo de confianza del 95% (IC95%) 0,47-0,95; p = 0,03; I2 = 53%; y con una reducción de la mortalidad cardiovascular en comparación con el control, RR 0,64, IC95% 0,44-0,94; p = 0,02; I2 = 54%. El uso de la VI se asoció con una reducción no estadísticamente significativa de infarto de miocardio en comparación con el control, RR 0,82, IC95% 0,60-1,12; p = 0,57; I2 = 0%. Conclusión : En este metaanálisis de seis ensayos controlados aleatorizados, la VI se asoció con una reducción del riesgo relativo del 33% y del 36% de la mortalidad por todas las causas y cardiovascular, respectivamente, en pacientes con ECV. Intentamos promover un consenso con respecto a los beneficios persistentes de la vacuna contra la influenza en pacientes con ECV, incluyendo dos nuevos ensayos clínicos en EAC e IC, donde se confirma la asociación de la vacunación con la reducción de riesgo en sujetos con ECV.

ABSTRACT Background : Influenza is a major cause of morbidity and mortality in patients with cardiovascular disease (CVD). The aim of this updated systematic review and meta-analysis was to evaluate the effect of influenza vaccination (IV) on morbidity and morbidity in adult patients with CVD. Methods : We conducted a systematic review and meta-analysis (PubMed, Cochrane Library, International Clinical Trials Registry Platform, and manual search of conference presentations) of randomized clinical trials published up to April 2022 analyzing whether IV reduced all-cause mortality in adult patients with CVD, including heart failure (HF) and coronary artery disease (CAD), compared with patients who were not vaccinated. Results : A total of six clinical trials comprising 9316 patients were analyzed. Five trials included CAD patients, and one trial included HF patients. Mean follow-up was 16 ± 9.7 months. Influenza vaccine was associated with a reduction of mortality compared to controls: relative risk (RR) 0.67 (95% CI, 0.47-0.95), p = 0.03; I2 = 53%, and with reduction of cardiovascular mortality compared to controls: RR 0.64 (95% CI, 0.44-0.94), p = 0.02; I2 = 54%. There was a non-statistically significant reduction in myocardial infarction compared to control: RR 0.82 (95% CI, 0.60-1.12), p = 0.57; I2 = 0%. Conclusion : In this meta-analysis of six randomized controlled clinical trials, IV was associated with a 33% and 36% relative risk reduction of all-cause mortality and cardiovascular mortality, respectively, in patients with CVD. We sought to promote consensus about the persistent benefits of influenza vaccination in patients with CVD by including two new clinical trials in CAD and HF, confirming the association of vaccination with risk reduction in subjects with CVD.

The DIVERSE Study: Determining the Importance of Various gEnders, Races, and Body Shapes for CPR Education Using Manikins.

Certain demographic groups are less likely to receive efficient Cardiopulmonary resuscitation (CPR), and poor representation of these groups in the manikins used for CPR simulation may play a role. The aim of the DIVERSE Study was to survey organizations that teach CPR to determine the demographic characteristics of the manikins they utilize for simulations. Institutions, businesses, and non-governmental organizations which provide CPR certification in North and Latin America were surveyed through a collaboration with the Emerging Leaders group of the Interamerican Society of Cardiology (SIAC). A total of 56 survey responses were received from North America (n = 18; 869 total manikins) and Latin America (n = 38; 1514 total manikins). Of the total manikins (n = 2383), 12% were non-white, 6% represented women, <1% represented a non-lean body habitus, and 1% represented pregnant individuals. Despite the importance of diverse manikin representation in simulation training, diverse representation is lacking in manikins used in North and Latin America.

Comparison of violence and aggressions suffered by health personnel during the COVID-19 pandemic in Argentina and the rest of Latin America. / Comparación de la violencia y agresiones sufridas por el personal de salud durante la pandemia de COVID-19 en Argentina y el resto de Latinoamérica.

OBJECTIVES.: Motivation for the study. The COVID-19 pandemic has caused profound repercussions at different socio-environmental levels. Its impact on violence against healthcare team workers in Argentina has not been well documented. Main findings. The present study evidenced high rates of aggression, particularly verbal aggression. In addition, almost half of the participants reported having suffered these events on a weekly basis. All participants who experienced violence reported having experienced post-event symptoms, and up to one-third reported having considered changing their profession after these acts. Implications. It is imperative to take action to prevent acts of violence against health personnel, or to mitigate its impact on the victims. . To explore the frequency and impact of violence against healthcare workers in Argentina and to compare it with the rest of their Latin American peers during the COVID-19 pandemic. MATERIALS AND METHODS.: A cross-sectional study was conducted by applying an electronic survey on Latin American medical and non-medical personnel who carried out health care tasks since March 2020. We used Poisson regression to estimate crude (PR) and adjusted (aPR) Prevalence Ratios with their respective 95% confidence intervals. RESULTS.: A total of 3544 participants from 19 countries answered the survey; 1992 (56.0%) resided in Argentina. Of these, 62.9% experienced at least one act of violence; 97.7% reported verbal violence and 11.8% physical violence. Of those who were assaulted, 41.5% experienced violence at least once a week. Health personnel from Argentina experienced violence more frequently than those from other countries (62.9% vs. 54.6%, p<0.001), and these events were more frequent and stressful (p<0.05). In addition, Argentinean health personnel reported having considered changing their healthcare tasks and/or desired to leave their profession more frequently (p<0.001). In the Poisson regression, we found that participants from Argentina had a higher prevalence of violence than health workers from the region (14.6%; p<0.001). CONCLUSIONS.: There was a high prevalence of violence against health personnel in Argentina during the COVID-19 pandemic. These events had a strong negative impact on those who suffered them. Our data suggest that violence against health personnel may have been more frequent in Argentina than in other regions of the continent.

Snakebite Envenomation and Heart: Systematic Review.

Snakebite envenomation is a neglected tropical disease which can result in morbidity and mortality. Cardiac implications are poorly understood due to the low frequency of cardiotoxicity combined with a lack of robust information, as snakebites commonly occur in remote and rural areas. This review aims to assess cardiovascular implications of snakebite envenoming and proposes an algorithm for screening of cardiovascular manifestations. A systematic review was performed and 29 articles relating to cardiovascular involvement in snakebite envenomation were selected. Cardiovascular involvement seems to be rare and includes a wide spectrum of outcomes, such as myocardial infarction, ventricular dysfunction, hypotension, cardiac arrest, and myocarditis. In a significant proportion of the cases analyzed (24.39%), the cardiovascular manifestations had major consequences (cardiac arrest, myocardial infarction, malignant ventricular arrhythmias, or death). Clinical monitoring, physical examination, and early electrocardiogram should be considered as key measures to detect cardiovascular involvement in patients with evidence of systemic illness.

Burnout Syndrome in Cardiology Residents. Impact of the COVID-19 Pandemic on Burnout Syndrome in Cardiology Residents.

Burnout syndrome (BO) may be increased during periods of high work and emotional stress, as occurred in the 2019 coronavirus disease pandemic (COVID-19). Resident physicians appear to be more exposed due to the higher workload, prolonged exposure and the first contact with patients. To compare the incidence of burnout syndrome before and during the COVID 19 pandemic in cardiology residents. A prospective study was carried out. The Maslach questionnaire was implemented in cardiology residents of an institution of the City of Buenos Aires, in the month of September 2020, during the COVID-19 pandemic and the results were compared with those prospectively collected in the same population during September of 2019. The survey was anonymous. The questionnaire was responded by 39 residents (2019: 16; 2020: 23). Burnout was observed in 30% (n = 7) in 2019, and in 39% (9%) residents during the COVID-19 pandemic (P= 0.77). The median score for emotional exhaustion was 38 (IQR 29-43) for the 2020s group, and 34 (IQR 27-42) for the 2019 (P = 0.32). The median score for depersonalization was 12 (IQR 5-19) and 15 (IQR 11-18) for 2020 and 2019 respectively (P = 0.50). The median score for personal accomplishment in the 2020s group was 30 (IQR 23-37) and 31 (IQR 26-35) in the 2019s (P = 0.28). The COVID-19 pandemic was not associated with an increase in the incidence of burnout in cardiology residents, who already report a significant prevalence of this syndrome in pre pandemic period. We emphasize the importance of creating prevention strategies aimed at improving resident's working conditions and quality of life, especially in periods of high stress and workload such as a global health emergency.

New combined risk score to predict atrial fibrillation after cardiac surgery: COM-AF.

Background and Aims: Atrial fibrillation frequently occurs in the postoperative period of cardiac surgery, associated with an increase in morbidity and mortality. The scores POAF, CHA2DS2-VASc and HATCH demonstrated a validated ability to predict atrial fibrillation after cardiac surgery (AFCS). The objective is to develop and validate a risk score to predict AFCS from the combination of the variables with highest predictive value of POAF, CHA2DS2-VASc and HATCH models. Methods: We conducted a single-center cohort study, performing a retrospective analysis of prospectively collected data. The study included consecutive patients undergoing cardiac surgery in 2010-2016. The primary outcome was the development of new-onset AFCS. The variables of the POAF, CHA2DS2-VASc and HATCH scores were evaluated in a multivariate regression model to determine the predictive impact. Those variables that were independently associated with AFCS were included in the final model. Results: A total of 3113 patients underwent cardiac surgery, of which 21% presented AFCS. The variables included in the new score COM-AF were: age (≥75: 2 points, 65-74: 1 point), heart failure (2 points), female sex (1 point), hypertension (1 point), diabetes (1 point), previous stroke (2 points). For the prediction of AFCS, COM-AF presented an AUC of 0.78 (95% CI 0.76-0.80), the rest of the scores presented lower discrimination ability (P < 0.001): CHA2DS2-VASc AUC 0.76 (95% CI 0.74-0.78), POAF 0.71 (95% CI 0.69-0.73) and HATCH 0.70 (95% CI: 0, 67-0.72). Multivariable analysis demonstrated that COM-AF score was an independent predictor of AFCS: OR 1,91 (IC 95% 1,63-2,23). Conclusion: From the combination of variables with higher predictive value included in the POAF, CHA2DS2-VASc, and HATCH scores, a new risk model system called COM-AF was created to predict AFCS, presenting a greater predictive ability than the original ones. Being necessary future prospective validations.

[Neglected tropical diseases and their impact on cardiovascular health (The NET-Heart Project)]. / Enfermedades tropicales desatendidas y su impacto sobre la salud cardiovascular (The NET-Heart Project).

Neglected tropical diseases (NTD) are a group of diseases with high prevalence in tropical and subtropical countries. They are associated to poverty and underdevelopment. Due to its high morbimortality, these conditions are considered a health crisis. The impact of these diseases can be worsened by the poor socioeconomic status of the affected countries, most of them under-developed, which affects the health care provided to patients. The morbidity of these diseases is explained by the wide organic impairment that they produce. The cardiovascular system is particularly affected, which explains the high morbimortality of NTD. In this article, we review the key issues of a project elaborated by Emerging Leaders of the Interamerican Society of Cardiology (SIAC), about the cardiovascular impact of NTD: the NET-Heart Project (Neglected Tropical Diseases and other Infectious Diseases affecting the Heart).

Las enfermedades tropicales desatendidas (ETD) constituyen un conjunto de afecciones altamente prevalentes en regiones tropicales y subtropicales, asociadas a pobreza y subdesarrollo. Constituyen una verdadera crisis sanitaria, incapacitando y llevando a la muerte a millones de personas anualmente.

Enfermedades tropicales desatendidas y su impacto sobre la salud cardiovascular (The NET-heart project) / Neglected tropical diseases and their impact on cardiovascular health. (The NET-Heart Project)

Resumen Las enfermedades tropicales desatendidas (ETD) constituyen un conjunto de afecciones altamente prevalentes en regiones tropicales y subtropicales, asociadas a pobreza y subdesarrollo. Constituyen una verdadera crisis sanitaria, incapacitando y llevando a la muerte a millones de personas anualmente. Esto se ve potenciado por las dificultades socioeconómicas que cursan estos países, mayormente en vías de desa rrollo, lo cual repercute en la calidad de la asistencia sanitaria que pueden proveer a la población. La morbilidad de estas enfermedades se explica por la amplia afectación orgánica que generan. El aparato cardiovascular resulta particularmente afectado, lo que explica en gran medida la morbimortalidad de las ETD. En el presente artículo se revisan los aspectos fundamentales de un proyecto llevado a cabo por los Líderes Emergentes de la Sociedad Interamericana de Cardiología (SIAC), cubriendo diferentes aspectos del impacto sobre el aparato cardiovascular de las ETD: el Proyecto NET-Heart (del inglés, Neglected Tropical Diseases and other Infectious Diseases Affecting the Heart).

Abstract Neglected tropical diseases (NTD) are a group of diseases with high prevalence in tropical and subtropi cal countries. They are associated to poverty and underdevelopment. Due to its high morbimortality, these conditions are considered a health crisis. The impact of these diseases can be worsened by the poor socioeconomic status of the affected countries, most of them under-developed, which affects the health care provided to patients. The morbidity of these diseases is explained by the wide organic impairment that they produce. The cardiovascular system is par ticularly affected, which explains the high morbimortality of NTD. In this article, we review the key issues of a project elaborated by Emerging Leaders of the Interamerican Society of Cardiology (SIAC), about the cardiovascular impact of NTD: the NET-Heart Project (Neglected Tropical Diseases and other Infectious Diseases affecting the Heart).

Utilización de oxigenación por membrana extracorpórea venoarterial en el shock cardiogénico y paro cardiorrespiratorio refractarios: experiencia inicial de 7 años en un centro de cardiología de adultos / Venoarterial Extracorporeal Membrane Oxygenation for Refractory Cardiogenic Shock and Cardiac Arrest: An Initial 7-Year Experience in an Adult Cardiology Center

RESUMEN Introducción: La oxigenación por membrana extracorpórea venoarterial (ECMO VA) es una intervención de rescate en pacientes con shock cardiogénico (SC), y paro cardiorrespiratorio (PCR) refractarios a las terapias convencionales. Objetivo: Describir las características, y resumir nuestra experiencia inicial de 7 años de pacientes que requirieron ECMO VA por SC o PCR. Material y métodos: Se realizó un estudio de cohorte unicéntrico. Se analizaron retrospectivamente los pacientes adultos consecutivos que fueron asistidos con ECMO VA por SC o PCR refractarios entre 2014 y 2020 en el ICBA Instituto Cardiovascular. Resultados: Se incluyeron 54 pacientes, (54 ± 12 años). El 36,5% presentó miocardiopatía isquémica, y el 23,1% enfermedad valvular significativa. Las indicaciones para ECMO VA fueron: poscardiotomía (43,4%), SC refractario (28,3%), y falla primaria del injerto (20,8%). La reanimación cardiopulmonar previa a la ECMO VA se realizó en el 18,5%. La canulación fue periférica en el 81,5%, el 83,3% se asistió en INTERMACS 1, y el 87% presentaba balón de contrapulsación intraaórtico. La duración de asistencia en ECMO VA fue de 5,5 días (RIC 2,8-10). La tasa de supervivencia en ECMO VA fue del 63% (37% puente a trasplante cardíaco, y 26% recuperación), y al alta del 42,6%. Las complicaciones más frecuentes fueron: sangrado (61,1%), infección (51,9%), y complicaciones tromboembólicas (46,3%). Conclusión: La ECMO VA como tratamiento del SC o PCR refractarios en nuestro centro presentó una sobrevida aceptable al alta hospitalaria. La ECMO VA es un tratamiento efectivo cuando las terapias convencionales fallan, siendo aparentemente útil y aplicable en un país donde existe acceso limitado a los dispositivos de asistencia ventricular compleja.

ABSTRACT Background: Venoarterial extra corporeal membrane oxygenation (VA-ECMO) is a rescue intervention used in patients with cardiogenic shock (CS) or cardiac arrest (CA) refractory to conventional medical therapies. Objective: The aim of the present study is to describe the characteristics and summarize our 7-year experience in patients with CS or CA supported with VA-ECMO. Methods: We conducted a single-center retrospective study analyzing consecutive adult patients requiring VA-ECMO due to refractory CS or CA at ICBA, Instituto Cardiovascular between January 2014 and December 2020. Results: A total age 54 patients were included (54 ± 12 years), 36.5% presented ischemic cardiomyopathy and 23.1% significant valvular heart disease. The indications for VA-ECMO implantation were post-cardiotomy (43.4%), refractory CS (28.3%) and primary graft dysfunction (20.8%). Cardiopulmonary resuscitation before VA-ECMO occurred in 18.5% of the cases. Peripheral cannulation was performed in 81.5% of the cases, 83.3% had INTERMACS profile 1 and 87% were on intraaortic balloon pump. Duration of ventricular assistance on VA- ECMO was 5.5 days (IQR 2.8-10). Survival rate on ECMO VA was 63% (37% as a bridge to cardiac transplantation and 26% as a bridge to recovery) and survival to discharge was 42.6%. The most common complications were hemorrhage (61.1%), infections (51.9%), and thromboembolic complications (46.3%). Conclusion: In our center, VA-ECMO as a treatment for refractory CS or CA showed acceptable survival during ventricular support and on hospital discharge. It is an effective life support treatment to rescue critically ill patients when conventional therapies fail, is apparently useful and can be implemented in a country with limited resources and access to complex ventricular assist devices.

Does high sensitivity troponin add prognostic value to validated risk scores to predict in-hospital mortality in patients with acute heart failure?

Troponin elevation correlates with an increased short and long-term mortality in patients with acute decompensated heart failure (AHF). However, it has not been included in the development of multiple validated predictive models of mortality. We aim to  determine whether the addition of high-sensitivity troponin T (hs-TnT) to clinical risk scores improves the prediction of in-hospital mortality in patients with AHF. A retrospective analysis of a prospective and consecutive cohort was performed. Adult patients hospitalized between 2015 and 2019 with a primary diagnosis of AHF were included. Hs-TnT was measured on admission. OPTIMIZE-HF, GWTG-HF, and ADHERE risks score were calculated for each patient. The primary endpoint was all-cause in-hospital mortality. Discrimination of isolated hs-TnT and the risk scores with and without the addition of hs-TnT were evaluated using the area under the ROC curve (AUC-ROC). A subanalysis was performed according to left ventricular ejection fraction (LVEF). Of 712 patients, 562 (79%) had hs-TnT measurement upon admission, and was elevated in 91%. In-hospital mortality was 8.7% (n = 49). The AUC-ROC was 0.70 (95% CI 0.63-0.77) for isolated hs-TnT, and 0.80 (0.74-0.87), 0.79 (0.72 -0.86) and 0.79 (0.71-0.86) for the OPTIMIZE-HF, GWTG-HF and ADHERE scores, respectively. The addition of hs-TnT to the models did not increase the AUC: 0.72 (0.66-0.79) for the OPTIMIZE-HF + hs-TnT score (difference between AUC - 0.08 p = 0.04), 0.74 (0.68-0.80) for GWTG-HF (difference between AUC-0.04, p = 0.2) and 0.7 (0.63-0.77) for ADHERE (difference between AUC - 0.085 p = 0.07). The models presented good calibration (p > 0.05). In the sub-analysis, no differences were found between risk scores with the addition of hs-TnT in the population with LVEF < 40% and ≥ 40%. Elevated hs-TnT on admission was frequent and its incorporation into the validated risk scores did not prove an incremental prognostic benefit in patients hospitalized for AHF, regardless of LVEF. Isolated hs-TnT had a modest ability to predict hospital mortality. Additional prospective studies are needed to validate these findings.
