RESUMO
Introducción. Los traumatismos cardíacos son lesiones graves y con elevado índice de letalidad, aspecto que influye en el interés mostrado por los lectores cada vez que aparecen reportados en publicaciones científicas. En ocasiones existe cierto grado de incongruencia a la hora de establecer el origen histórico de sucesos o eventos ocurridos y relacionados con la historia de la medicina. En el caso del trauma cardíaco penetrante han sido descritos diversos orígenes en algunos de los artículos científicos publicados, lo cual puede generar un grado de duda en los lectores. Métodos. Se realizó una revisión de la literatura, médica y no médica, para buscar información que ayudara a esclarecer el verdadero origen histórico de esta entidad. Resultados. El trauma cardíaco penetrante fue descrito por primera vez en la obra griega titulada La Ilíada, escrita por Homero en el siglo VIII A.C., y no en El papiro quirúrgico de Edwin Smith, como varios autores mencionan. Conclusiones. De todos los eventos de trauma cardíaco penetrante descritos, el más irrefutable es el narrado en el canto XIII, donde se cuenta la muerte de Alcátoo, producto de una herida cardíaca ocasionada por una lanza arrojada por Idomeneo durante una batalla
Introduction. Cardiac traumatic injuries are serious injuries with a high lethality rate, an aspect that influences the interest shown by readers each time they appear reported in scientific publications. Sometimes there is a certain degree of inconsistency when it comes to establishing the historical origin of occurrences or events related to the history of medicine. In the case of penetrating cardiac trauma, different origins have been described in some of the published scientific articles, which may generate a degree of doubt in the readers. Methods. A review of the medical and non-medical literature was carried out to seek information that would help to clarify the true historical origin of this entity. Results. Penetrating cardiac trauma was first described in a Greek work entitled The Iliad, written by Homer in the 8th century B.C., and not in The Surgical Papyrus of Edwin Smith as several authors mention. Conclusions. Of all the events of penetrating cardiac trauma described, the most irrefutable is the one narrated in canto XIII, where it recounts the death of Alcathous product of a cardiac wound caused by a spear thrown by Idomeneo during a battle.

Introducción. La incidencia reportada de traumatismo cardíaco es baja y su grado de resolución es variable, dependiendo de la causa, el mecanismo de la lesión, el lugar donde ocurra y las características del sistema sanitario. Su incidencia ha aumentado recientemente debido al incremento de los accidentes de tránsito y la violencia, predominando los traumatismos penetrantes asociados a heridas por armas cortopunzantes y de fuego. Los traumatismos cardíacos se acompañan de un alto grado de letalidad. Caso clínico. Mujer de 35 años que consultó a emergencia por trauma torácico penetrante ocasionado por arma blanca y fue intervenida de urgencia por derrame pleural izquierdo, sin mejoría hemodinámica. Fue reevaluada detectándose derrame pericárdico con taponamiento cardíaco, ocasionado por lesión cardíaca. Fue tratada quirúrgicamente con resultados satisfactorios. Resultados. Las manifestaciones clínicas en los traumatismos penetrantes generalmente son graves y fatales, pero en algunos casos puede no comprometer tanto la hemodinamia del paciente. Para consolidar el diagnóstico clínico pueden realizarse variados estudios, siendo la ecografía FAST extendida uno de los más recomendados por su elevada sensibilidad y especificidad. Dependiendo del adelanto tecnológico del centro hospitalario y la estabilidad hemodinámica del paciente, el tratamiento quirúrgico es el más indicado. Conclusión. El conocimiento del trauma cardíaco penetrante resulta de gran importancia, no solo para el médico del servicio de emergencia sino también para el médico general. Un diagnóstico rápido y acertado, unido a un manejo adecuado, pueden ser decisivos para salvar la vida del paciente.
Introduction. The reported incidence of cardiac trauma is low and its degree of resolution is variable depending on the cause, the mechanism of injury, the place where it occurs and the characteristics of the health care system. Their incidence has currently increased due to the increase in traffic accidents and violence, with a predominance of penetrating trauma associated with stab wounds and firearms. Cardiac trauma is accompanied by a high degree of lethality. Clinical case. A 35-year-old female patient, evaluated in the emergency room for penetrating thoracic trauma caused by stab wound. She underwent emergency intervention due to left pleural effusion, but without hemodynamic improvement. She was reevaluated and pericardial effusion with cardiac tamponade caused by cardiac injury was detected. She was treated surgically with satisfactory results. Results.The clinical manifestations generally described in penetrating cardiac trauma are severe and fatal, but in some cases and due to the characteristics of the injury caused, the patient's hemodynamics may not be so compromised. To consolidate the clinical diagnosis, several complementary studies can be performed, with FAST ultrasound being one of the most recommended due to its high sensitivity and specificity. Surgical treatment is still the most indicated, depending on the technological progress of the hospital and the hemodynamic stability of the patient. Conclusions.Knowledge of penetrating cardiac trauma is of great importance, not only for the emergency department physician but also for the general practitioner. A quick and accurate diagnosis, together with adequate management can be decisive in saving the patient's life.

This study aimed to investigate the effect of Wenyang Zhenshuai Granules(WYZSG) on autophagy and apoptosis of myocardial cells in rats with sepsis via regulating the expression of microRNA-132-3p(miR-132-3p)/uncoupling protein 2(UCP2). Sixty SD rats were randomly divided into modeling group(n=50) and sham operation group(n=10). The sepsis rat model was constructed by cecal ligation and perforation in the modeling group. The successfully modeled rats were randomly divided into WYZSG low-, medium-and high-dose groups, model group and positive control group. Rats in the sham operation group underwent opening and cecum division but without perforation and ligation. Hematoxylin-eosin(HE) staining was used to observe the pathological changes of rat myocardial tissue. Myocardial cell apoptosis was detected by TdT-mediated dUTP nick end labeling(TUNEL) assay. Real-time quantitative polymerase chain reaction(RT-qPCR) was performed to detect the expression of miR-132-3p and the mRNA expressions of UCP2, microtubule-associated protein light chain 3(LC3-Ⅱ/LC3-Ⅰ), Beclin-1 and caspase-3 in rat myocardial tissue. The protein expressions of UCP2, LC3-Ⅱ/LC3-Ⅰ, Beclin-1 and caspase-3 in myocardial tissue were detected by Western blot. Dual luciferase reporter assay was used to verify the regulatory relationship between miR-132-3p and UCP2. The myocardial fibers of sepsis model rats were disordered, and there were obvious inflammatory cell infiltration as well as myocardial cell edema and necrosis. With the increase of the WYZSG dose, the histopathological changes of myocardium were improved to varying degrees. Compared with the conditions in the sham operation group, the survival rate and left ventricular ejection fraction(LVEF) of rats in the model group, positive control group and WYZSG low-, medium-and high-dose groups were decreased, and the myocardial injury score and apoptosis rate were increased. Compared with the model group, the positive control group and WYZSG low-, medium-and high-dose groups had elevated survival rate and LVEF, and lowered myocardial injury score and apoptosis rate. The expression of miR-132-3p and the mRNA and protein expressions of UCP2 in myocardial tissue in the model group, positive control group and WYZSG low-, medium-and high-dose groups were lower, while the mRNA and protein expressions of LC3-Ⅱ/LC3-Ⅰ, Beclin-1 and caspase-3 were higher than those in the sham operation group. Compared with model group, the positive control group and the WYZSG low-, medium-and high-dose groups had an up-regulation in the expression of miR-132-3p and the mRNA and protein expressions of UCP2, while a down-regulation in the mRNA and protein expressions of LC3-Ⅱ/LC3-Ⅰ, Beclin-1 and caspase-3. WYZSG inhibited excessive autophagy and apoptosis of myocardial cells in septic rats and improved myocardial injury, possibly by regulating the expression of miR-132-3p/UCP2.

This paper aimed to study the effect of Dalbergia cochinchinensis heartwood on plasma endogenous metabolites in rats with ligation of the left anterior descending coronary artery, and to analyze the mechanism of D. cochinchinensis heartwood in improving acute myocardial ischemic injury. The stability and consistency of the components in the D. cochinchinensis heartwood were verified by the establishment of fingerprint, and 30 male SD rats were randomly divided into a sham group, a model group, and a D. cochinchinensis heartwood(6 g·kg~(-1)) group, with 10 rats in each group. The sham group only opened the chest without ligation, while the other groups established the model of ligation. Ten days after administration, the hearts were taken for hematoxylin-eosin(HE) staining, and the content of heart injury indexes in the plasma creatine kinase isoenzyme(CK-MB) and lactate dehydrogenase(LDH), energy metabolism-related index glucose(Glu) content, and vascular endothelial function index nitric oxide(NO) was determined. The endogenous metabolites were detected by ultra-high-performance liquid chromatography-time-of-flight-mass spectrometry(UPLC-Q-TOF-MS). The results showed that the D. cochinchinensis heartwood reduced the content of CK-MB and LDH in the plasma of rats to relieve myocardial injury, reduced the content of Glu in the plasma, improved myocardial energy metabolism, increased the content of NO, cured the vascular endothelial injury, and promoted vasodilation. D. cochinchinensis heartwood improved the increase of intercellular space, myocardial inflammatory cell infiltration, and myofilament rupture caused by ligation of the left anterior descending coronary artery. The metabolomic study showed that the content of 26 metabolites in the plasma of rats in the model group increased significantly, while the content of 27 metabolites decreased significantly. Twenty metabolites were significantly adjusted after the administration of D. cochinchinensis heartwood. D. cochinchinensis heartwood can significantly adjust the metabolic abnormality in rats with ligation of the left anterior descending coronary artery, and its mechanism may be related to the regulation of cardiac energy metabolism, NO production, and inflammation. The results provide a corresponding basis for further explaining the effect of D. cochinchinensis on the acute myocardial injury.

The lymphatic system of the heart plays an important role in the repair process after myocardial injury and may regulate normal tissue homeostasis and natural regeneration via maintaining fluid homeostasis and controlling the inflammatory response. The lymphatic system in the heart is activated after myocardial injury and is involved in the scarring process of the heart. Recent studies on the lymphatic system and myocardial repair of the heart have developed rapidly, and the mechanisms for lymphangiogenesis and lymphatic endothelial cell secretion have been elucidated by different animal models. A deep understanding of the structural, molecular, and functional characteristics of the lymphatic system of the heart can help develop therapies that target the lymphatic system in the heart. Summarizing the progress in studies on targets related to myocardial repair and the cardiac lymphatic system is helpful to provide potential new targets and strategies for myocardial repair therapy after myocardial infarction.

OBJECTIVE@#To explore the contribution of ferroptosis to myocardial injury in mouse models of sepsis and the role lipocalin-2 (Lcn2) in ferroptosis.@*METHODS@#Adult male C57BL/6 mice were randomized equally into sham-operated group, cecal ligation and puncture (CLP)-induced sepsis group, and CLP + Fer-1 group where the mice received intraperitoneal injection of 5 mg/mL Fer-1 (5 mg/kg) 1 h before CLP. The left ventricular functions (including LVEF%, LVFS%, LVIDd and LVIDs) of the mice were assessed by echocardiography at 24 h after CLP. Myocardial injury in the mice was observed with HE staining, and the changes of myocardial ultrastructure and mitochondria were observed using transmission electron microscopy (TEM). Serum TNF-α level was measured with ELISA, and the changes of myocardial iron content were detected using tissue iron kit. The protein expressions of myocardial Lcn2, glutathione peroxidase 4 (GPX4) and ferroptosis suppressor protein 1 (FSP1) were determined with Western blotting.@*RESULTS@#The septic mice showed significantly decreased LVEF%, LVFS% and LVIDd and increased LVIDs at 24 h after CLP (P < 0.05), and these changes were significantly improved by Fer-1 treatment. Sepsis caused obvious myocardial pathologies and changes in myocardial ultrastructure and mitochondria, which were significantly improved by Fer-1 treatment. Fer-1 treatment also significantly ameliorated sepsis-induced elevations of serum TNF-α level, myocardial tissue iron content, and Lcn2 protein expression and the reduction of GPX4 and FSP1 protein expression levels (P < 0.05).@*CONCLUSION@#GPX4- and FSP1-mediated ferroptosis are involved in myocardial injury in mice with CLP-induced sepsis, and inhibition of ferroptosis can attenuate septic myocardial injury, in which Lcn2 may play a role.

OBJECTIVE@#To evaluate the protective effect of excretory-secretory proteins from Trichinella spiralis muscle larvae (Ts-MES) on sepsis-induced myocardial injury in mice.@*METHODS@#Eighty male BALB/C mice were randomized equally into sham-operated group, myocardial injury group, Ts-MES treatment group and dexamethasone treatment group. In the latter 3 groups, sepsis-induced myocardial injury models were established by cecal ligation and perforation; the sham operation was performed by exposure of the cecum without ligation or perforation. Forty minutes after the operation, the mice were given intraperitoneal injections 150 μL PBS, 20 μg TS-MES or 0.3 mg/kg dexamethasone as indicated. At 12 h after the operation, 6 mice were randomly selected from each group for echocardiography, and 8 mice were used for observing the survival rate within 72 h. The remaining 6 mice were examined for myocardial pathologies with HE staining and serum levels of NTPro-BNP and cTnI with ELISA; the expressions of TNF-α, IL-6, IL-10 and TGF-β in the serum and myocardial tissue were detected using ELISA and qRT-PCR.@*RESULTS@#Compared with the sham-operated mice, the septic mice showed significantly decreased cardiac function indexes (LVEF, LVFS, and E/A) with lowered survival rate within 72 h (P < 0.001) and significantly higher myocardial injury scores and serum levels of NTPro-BNP and cTnI (P < 0.01). Treatment with TS-MES significantly improved the cardiac function and 72-h survival rate (P < 0.05) and lowered the myocardial injury scores and serum levels of NTPro-BNP and cTnI (P < 0.05) in the septic mice. Compared with the sham-operated mice, the septic mice had obviously increased TNF-α and IL-6 levels in the serum and myocardial tissue (P < 0.001), which were significantly lowered by treatment with TS-MES (P < 0.05). TS-MES and dexamethasone both increased the levels of IL-10 and TGF-β in the septic mice, but the changes were significant only in TS-MES-treated mice (P < 0.05).@*CONCLUSION@#Ts-MES are capable of protecting against myocardial injury in septic mice by reducing the production of pro-inflammatory cytokines and enhancing the levels of regulatory cytokines.

Fundamento: A ecocardiografia avançada com utilização de strain miocárdico bi e tridimensional propõe identificar a disfunção sistólica subclínica em diversas condições clínicas. No diabetes mellitus, seu papel é de grande interesse para diagnóstico precoce de cardiomiopatia diabética. Contudo, há grande heterogeneidade nos artigos publicados. Objetivo: Realizar uma revisão sistemática, para avaliar o papel atual da avaliação com strain nos pacientes com diabetes mellitus. Métodos: Após revisão sistemática em cinco bancos de dados, 19 estudos que utilizaram strain bidimensional e oito estudos que utilizaram strain tridimensional foram incluídos. Resultados:Na avaliação por strain bidimensional, a amostra totalizou 1.774 indivíduos com diabetes mellitus, com idade média de 57,1 anos e mediana de 55 anos, com equilíbrio em relação ao sexo dos participantes (47,5% do sexo feminino). Nos estudos que utilizaram strain tridimensional, foram incluídos 488 indivíduos com diabetes, com idade média de 55,7 anos e mediana de 63 anos, também com equilíbrio entre o sexo dos pacientes (51% do sexo feminino). O strain global longitudinal foi o marcador de deformação miocárdica que mais frequentemente conseguiu demonstrar diferença entre grupos com indivíduos diabéticos e controles. Conclusão: O strain miocárdico por speckle tracking bi e tridimensional permite identificar disfunção sistólica subclínica em pacientes diabéticos, o que se torna mais marcante nos pacientes com mais fatores de risco associados e com remodelamento ventricular.(AU)
Background: Advanced echocardiography using two- and three-dimensional myocardial strain proposes to identify subclinical systolic dysfunction in different clinical conditions. Strain assessment plays an important role in the early diagnosis of diabetic cardiomyopathy in diabetes mellitus (DM). However, the findings of published articles are heterogeneous. Here we conducted a systematic review to analyze the current role of strain assessment in patients with DM. Methods: This systematic review of five databases identified 19 studies that used twodimensional strain and 8 studies that used three-dimensional strain. Results: The studies of two-dimensional strain included 1,774 DM patients (mean age, 57.1 years; median age, 55 years; 47.5% women), while those of three-dimensional strain included 488 DM patients (mean age, 55.7 years; median age, 63 years; 51% women). Global longitudinal strain was the myocardial deformation marker that differed most frequently between the DM and control groups. Conclusion: Myocardial strain imaging by two- and three-dimensional speckle tracking echocardiography allows the identification of subclinical systolic dysfunction in DM patients, and differences become more marked when associated with risk factors and ventricular remodeling.(AU)

Resumo Aproximadamente 300 milhões de cirurgias não cardíacas são realizadas anualmente no mundo, e eventos cardiovasculares adversos são as principais causas de morbimortalidade no período perioperatório e pós-operatório. A lesão miocárdica após cirurgia não cardíaca (MINS, do inglês myocardial injury after non-cardiac surgery) é uma nova entidade clínica associada com desfechos cardiovasculares adversos. MINS é definida como uma lesão miocárdica que pode resultar em necrose secundária à isquemia, com elevação dos biomarcadores. A lesão tem importância prognóstica e ocorre em até 30 dias após a cirurgia não cardíaca. Os critérios diagnósticos para MINS são: níveis elevados de troponina durante ou em até 30 dias após a cirurgia não cardíaca, sem evidência de etiologia não isquêmica, sem que haja necessariamente sintomas isquêmicos ou achados eletrocardiográficos de isquemia. Recentemente, pacientes com maior risco para MINS têm sido identificados por variáveis clínicas e biomarcadores, bem como por protocolos de vigilância quanto ao monitoramento eletrocardiográfico e dosagem de troponina cardíaca. Pacientes idosos com doença aterosclerótica prévia necessitam medir troponina diariamente no período pós-operatório. O objetivo deste trabalho é descrever este novo problema de saúde pública, seu impacto clínico e a abordagem terapêutica contemporânea.
Abstract Approximately 300 million non-cardiac surgeries are performed annually worldwide and adverse cardiovascular events are the main cause of morbidity and mortality in the peri- and postoperative period. Myocardial injury after non-cardiac surgery (MINS) is a new clinical entity associated with adverse cardiovascular outcomes. MINS is defined as myocardial injury that can result in necrosis due to ischemia, marked by increase in biomarker levels. It has prognostic relevance and occurs within up to 30 days after non-cardiac surgery. The diagnostic criteria for MINS are an elevated postoperative measure of troponin judged as secondary to myocardial ischemia, i.e., with no evidence of a non-ischemic etiology, during or within 30 days after non-cardiac surgery, and without the requirement of an ischemic symptom or electrocardiographic finding of ischemia. Recently, patients at higher risk for MINS have been recognized using clinical variables and biomarkers and established protocols for greater surveillance in relation to electrocardiographic monitoring and cardiac troponin dosage. Elderly patients with previous atherosclerotic disease need to measure troponin daily in the postoperative period. The aim of the present work is to describe this new public health problem, its clinical impact and contemporary therapeutic approach.

Abstract Introduction: In high-volume trauma centers, especially in developing countries, penetrating cardiac box injuries are frequent. Although many aspects of penetrating chest injuries have been well established, video-assisted thoracoscopy is still finding its place in cardiac box trauma and algorithmic approaches are still lacking. The purpose of this manuscript is to provide a streamlined recommendation for penetrating cardiac box injury in stable patients. Methods: Literature review was carried out using PubMed/MEDLINE and Google Scholar databases to identify articles describing the characteristics and concepts of penetrating cardiac box trauma, including the characteristics of tamponade, cardiac ultrasound, indications and techniques of pericardial windows and, especially, the role of video-assisted thoracoscopy in stable patients. Results: Penetrating cardiac box injuries, whether by stab or gunshot wounds, require rapid surgical consultation. Unstable patients require immediate open surgery, however, determining which stable patients should be taken to thoracoscopic surgery is still controversial. Here, the classification of penetrating cardiac box injury used in Colombia is detailed, as well as the algorithmic approach to these types of trauma. Conclusion: Although open surgery is mandatory in unstable patients with penetrating cardiac box injuries, a more conservative and minimally invasive approach may be undertaken in stable patients. As rapid decision-making is critical in the trauma bay, surgeons working in high-volume trauma centers should expose themselves to thoracoscopy and always consider this possibility in the setting of penetrating cardiac box injuries in stable patients, always in the context of an experienced trauma team.

La mortalidad se ha mantenido estable a través del tiempo.
Background: Penetrating cardiac injury (PCI) is a rare injury with high morbidity and mortality. Aim: To analyze the evolution of clinical and anatomical characteristics, severity, morbidity and mortality of patients operated on by PCI. Materials and Methods: Analytical study of patients surgically treated for PCI at the "Guillermo Grant Benavente" Regional Clinical Hospital, Concepción, Chile. Two periods were analyzed: January-1990 to December-2004 and January-2005 to December-2019. Sex, age, associated injuries, trauma agent and mechanism, pathophysiological behavior, anatomic location of the injury, classifications of cardiac trauma: Attar, Saadia and OIS-AAST, TSI (trauma severity indices): ISS, RTS-T and TRISS, morbidity and mortality were compared according to periods. Statistical analysis was performed with SPSS25®, the chi-square, Fisher exact and Mann-Whitney tests were used. A p value < 0.05 was considered significant. Results: Total 235 PCI, 112 in the first period and 123 in the second. Stab as mechanism in 96 (85.7%) and 104 (84.6%) according to periods. An increase in associated extra thoracic injuries, cardiorespiratory arrest, and injury to the left location were observed in the second period. The cardiac trauma classifications and the TSI ISS, RTS-T and TRISS showed greater severity and probability of death in the second period patients. Mortality did not show differences: 14 (12.5%) and 14 (11.4%) according to periods, p = 0.792. Discussion: In our series, patients treated with PCI have evolved towards a more severity profile in both, physiological and anatomical parameters. Mortality has been stable over time.

Introducción. El manejo de la herida cardiaca penetrante es un reto dado que requiere un rápido manejo quirúrgico para evitar que su desenlace sea fatal. Múltiples factores pronósticos han sido descritos, sin embargo, no ha sido documentada la relación entre el tiempo de llegada a quirófano y el uso de pledgets con la mortalidad. Métodos. Se realizó un estudio observacional retrospectivo de corte transversal, desde el año 2011 hasta el año 2018, en un hospital universitario de la ciudad de Medellín. Se evaluaron los registros de los pacientes con herida cardiaca penetrante confirmada y se realizó análisis univariado, bivariado y multivariado, así como curvas de supervivencia. Resultados. Los pacientes inestables o con taponamiento cardiaco que llegan al quirófano después del minuto 4 de haber ingresado a urgencias tienen cuatro veces más posibilidades de morir que los que llegan a quirófano antes (RR 4,1 IC95% 1,4312,07). El uso de pledgets en el reparo de la herida cardiaca, corresponde a un factor protector para los pacientes, con un OR ajustado de 2,5 (IC95% 1,124-5,641). El tipo de traumatismo, la arritmia intraoperatoria y el índice de choque al ingreso también fueron factores pronósticos. Discusión. Se documenta el efecto del tiempo de llegada a quirófano sobre la mortalidad, lo cual permitirá en un futuro generar cambios en el manejo de estos pacientes en función de estos tiempos. La evidencia encontrada sugiere mejores desenlaces con el uso rutinario de pledgets
Introduction. The management of penetrating cardiac injury is challenging since it requires rapid surgical ma-nagement to avoid a fatal outcome. Multiple prognostic factors have been described, however, the relationship between the time of arrival to the operating room and the use of pledgets with mortality has not been documented.Methods. A cross-sectional retrospective observational study was conducted from 2011 to 2018 in a university hospital in the city of Medellín. Records of patients with confirmed penetrating cardiac injury were evaluated, and univariate, bivariate, and multivariate analyzes were performed, as well as survival curves.Results. Unstable patients or patients with cardiac tamponade who arrive to the operating room after 4 minutes after being admitted to the emergency room are four times more likely to die than those who arrive to the operating room earlier (RR 4.1 95% CI 1.4312.07). The use of pledgets in the repair of the cardiac wound corresponds to a protective factor for patients, with an adjusted OR of 2.5 (95% CI 1.124-5.641). The type of trauma, intraoperative arrhythmia and the shock index on admission were also prognostic factors. Discussion. The effect of the time of arrival to the operating room on mortality is documented, which will allow in the future to generate changes in the management of these patients based on these times. The evidence found suggests better outcomes with the routine use of pledgets

Introduction. Chest trauma is one of the most common causes of death corresponding to 20 to 25 % of cases. The majority of the patients (85%), can be managed with only a tube thoracostomy. Our objective by presenting this case report is to provide an example of how to manage a challenging chest tube thoracostomy in a patient with cardiac hernia diagnosed in the preoperative phase, based on signs of computed tomography. Case report. A 45-year-old male presented to our emergency department who fell from a light pole 7 meters high. He fell to the ground on his back. Physical examination revealed a huge subcutaneous emphysema on his entire anterior chest wall and presented no sensitivity or movements below the navel line. After the initial assessment and management care, the patient improved. As the patient stabilized we decided to go to CT. The scan revealed pericardial rupture with only the right pericardial circumference intact, the heart herniated into the left pleural space, bilateral pneumothorax, small right hemothorax and a relevant subcutaneous emphysema surrounding the chest. We decided to perform the blunt dissection technique to insert chest tubes bilaterally because of safety. After performed it the patient was transferred to cardiothoracic department. Discussion. There is a variety of techniques to perform tube thoracostomy but the blunt dissection remain the safer, especially when we are facing an anatomic distortion of the heart. Conclusion. We present a case report of a challenging thoracic drainage performed in a patient with traumatic cardiac hernia, which procedure was successful
Introducción. El traumatismo torácico es una de las causas más comunes de muerte y corresponde al 20 a 25 % de los casos. La mayoría de los pacientes (85 %) pueden tratarse solo con toracostomía. Nuestro objetivo al presentar este informe de caso es proporcionar un ejemplo de cómo manejar una toracostomía desafiante en un paciente con hernia cardíaca, diagnosticada en la fase preoperatoria, basada en signos de tomografía computarizada. Presentación del caso. Paciente masculino de 45 años que ingresa a nuestro departamento de emergencias luego de caída de 7 metros de altura (poste de luz), cayendo de espaldas al suelo. El examen físico reveló un enfisema subcutáneo importante en todo el tórax anterior y sin sensibilidad ni movimientos debajo de la línea del ombligo. Después de la evaluación y atención inicial el paciente mejoró y se decidió realizar una tomografía computarizada que reveló la rotura pericárdica, con solo la circunferencia pericárdica derecha intacta, el corazón herniado en el espacio pleural izquierdo, neumotórax bilateral, pequeño hemotórax en el lado derecho y enfisema subcutáneo rodeando completamente el tórax. Se escogió una técnica de disección roma para insertar el tubo torácico en ambos hemitórax, debido a su mayor seguridad. Posteriormente, el paciente fue trasladado al departamento de cirugía cardiotorácica. Discusión. Existe una variedad de técnicas para realizar una toracostomía con sonda, pero la disección roma sigue siendo la más segura, especialmente cuando enfrentamos una distorsión anatómica del corazón. Conclusión. Presentamos el caso de un drenaje torácico desafiante practicado a un paciente con hernia cardíaca traumática, con éxito.

ABSTRACT Purpose The present study explored the potential therapeutic role of oleuropein in sepsis-induced heart injury along with the role of GSK-3β/NF-kB signaling pathway. Methods Sepsis-induced myocardial injury was induced by cecal ligation and puncture (CLP) in rats. The cardiac injury was assessed by measuring the levels of cTnI and creatine kinase-MB (CK-MB). Sepsis-induced inflammation was assessed by measuring interleukin-6 (IL-6), IL-10 and HMGB1 levels. The different doses of oleuropein (5, 10, and 20 mg/kg) were given prior to CLP. Oleuropein (20 mg/kg) was administered after 6 hof CLP. The expressions of GSK-3β, p-GSK-3β (Ser9) and nuclear factor-κB (NF-κB) were measured in heart homogenates. Results Cecal ligation and puncture was associated with myocardial injury, an increase in IL-6, a decrease in IL-10 and an increase in HMGB1. Moreover, it decreased the ratio of p-GSK-3β/GSK-3β and increased the expression of p-NF-kB. Pretreatment with oleuropein attenuated CLP-induced myocardial injury and systemic inflammation in a dose-dependent manner. Administration of oleuropein after the onset of CLP also attenuated cardiac injury and inflammation. It also restored CLP-induced changes in the HMGB1 levels, the ratio of p-GSK-3β/GSK-3β and expression of p- NF-kB. Conclusions Oleuropein attenuates sepsis-induced systemic inflammation and myocardial injury by inhibiting NF-kB and GSK-3β signaling.

INTRODUCCION: El Síndrome Inflamatorio Pediátrico Multisistémico (PIMS) ha emergido como una nueva enfermedad en niños, secundaria a infección por SARSCoV-2. Se caracteriza por presentar compromiso multiorgánico con parámetros inflamatorios elevados y manifestaciones clínicas graves, siendo el corazón el órgano más severamente comprometido. OBJETIVO: Describir las características clínicas y de laboratorio de 23 pacientes con diagnóstico de PIMS con compromiso cardiovascular hospitalizados en un centro único. MÉTODO: Se efectuó un estudio retrospectivo analizando los hallazgos clínicos y de laboratorio junto a las manifestaciones cardiovasculares que presentaron estos pacientes. RESULTADOS: 23/29 pacientes con PIMS (78%) presentaron manifestaciones digestivas y mucocutáneas. Las manifestaciones cardiovasculares fueron: Síndrome Kawasaki y "Kawasaki like" sin compromiso coronario en 15/23 (65%) y con compromiso coronario en 3 (13%). Shock en 9 pacientes (39%), injuria miocárdica- miocarditis en 8 (35%) y derrame pericárdico en 13 (56%). Trastornos del ritmo cardíaco se observaron en 6 pacientes (26%). La terapia más utilizada fue inmunoglobulina y corticoides. 18 /23 requirieron manejo en unidades de intermedio y/o intensivo. Un 70% de los pacientes se recuperó del compromiso cardiovascular antes del alta. CONCLUSIÓN: El compromiso cardiovascular en PIMS es la complicación más frecuente de esta enfermedad, que se acompaña de manifestaciones inmunológicas y hematológicas graves lo que hace necesario un tratamiento multidisciplinario para un mejor manejo de estos pacientes.
INTRODUCTION: Pediatric Multisystemic Inflammatory Syndrome (PIMS) has emerged as a new disease in children, secondary to SARSCoV-2 infection. It is characterized by multi-organ involvement with elevated inflammatory parameters and severe clinical manifestations, the heart being the organ most severely involved. OBJETIVE: to describe the clinical and laboratory characteristics of 23 patients diagnosed with PIMS with cardiovascular involvement hospitalized in a single center. METHOD: We conducted a retrospective study in which we analyzed the clinical and laboratory findings along with the cardiovascular manifestations presented by these patients. Results: 23/29 patients with PIMS and cardiovascular involvement were selected, 78% had digestive and mucocutaneous manifestations. Cardiovascular manifestations consisted of KawasakiKawasaki like syndrome without coronary involvement in 15/23 (65%) and coronary involvement in 3 (13%). Nine patients developed shock (39%), 8 (35%) myocardial injury in and 13 (56%) pericardial effusion.. Heart rhythm disorders were observed in 6 patients (26%). The main therapy was immunoglobulin and corticosteroids. 18 /23 required management in intermediate and/or intensive care unit. 70% of patients recovered from cardiovascular involvement before discharge. CONCLUSION: Cardiovascular involvement in PIMS is the most frequent complication of this disease, but it is associated with severe immunological and hematological manifestations, which makes necessary a multidisciplinary treatment for a better management

Abstract Background: Cardioinhibitory carotid sinus hypersensitivity (CICSH) is defined as ventricular asystole ≥ 3 seconds in response to 5-10 seconds of carotid sinus massage (CSM). There is a common concern that a prolonged asystole episode could lead to death directly from bradycardia or as a consequence of serious trauma, brain injury or pause-dependent ventricular arrhythmias. Objective: To describe total mortality, cardiovascular mortality and trauma-related mortality of a cohort of CICSH patients, and to compare those mortalities with those found in a non-CICSH patient cohort. Methods: In 2006, 502 patients ≥ 50 years of age were submitted to CSM. Fifty-two patients (10,4%) were identified with CICSH. Survival of this cohort was compared with that of another cohort of 408 non-CICSH patients using Kaplan-Meier curves. Cox regression was used to examine the relation between CICSH and mortality. The level of statistical significance was set at 0.05. Results: After a maximum follow-up of 11.6 years, 29 of the 52 CICSH patients (55.8%) were dead. Cardiovascular mortality, trauma-related mortality and the total mortality rate of this population were not statistically different from that found in 408 patients without CICSH. (Total mortality of CICSH patients 55.8% vs. 49,3% of non-CICSH patients; p: 0.38). Conclusion: At the end of follow-up, the 52 CICSH patient cohort had total mortality, cardiovascular mortality and trauma-related mortality similar to that found in 408 patients without CICSH.
Resumo Fundamento: A resposta cardioinibitória (RCI) à massagem do seio carotídeo (MSC) caracteriza-se por assistolia ≥ 3 segundos provocada por 5 a 10 segundos de MSC. Existe uma preocupação de que pacientes com RCI e episódios prolongados de assistolia possam falecer em consequência direta de bradiarritmia, ou em decorrência de lesão cerebral, trauma grave ou arritmia ventricular pausa dependente. Objetivos: Determinar a mortalidade total, a mortalidade cardiovascular e a mortalidade relacionada ao trauma de uma coorte de pacientes com RCI à MSC e comparar essas mortalidades com as de uma coorte de pacientes sem RCI à MSC. Métodos: Em 2006, 502 pacientes com idade igual ou superior a 50 anos foram submetidos à MSC. Destes, 52 pacientes (10,4%) foram identificados com RCI. A sobrevida desta coorte foi comparada àquela observada em uma coorte de 408 pacientes sem RCI por meio de curvas de Kaplan-Meier. A regressão de Cox foi utilizada para avaliação da relação entre a RCI à MSC e a mortalidade. Variáveis com p < 0,05 foram consideradas estatisticamente significativas. Resultados: Após seguimento máximo de 11,6 anos, 29 dos 52 portadores de RCI (55,8%) faleceram. A mortalidade total, a mortalidade cardiovascular e a mortalidade relacionada ao trauma desta coorte de pacientes não foram significativamente diferentes daquelas encontradas nos 408 pacientes sem RCI (mortalidade total com RCI: 55,8% versus 49,3% sem RCI; p: 0,38). Conclusões: No fim do seguimento, a mortalidade dos 52 portadores de RCI foi semelhante à observada em uma coorte de pacientes sem RCI. A mortalidade cardiovascular e a relacionada ao trauma também foi semelhante nas duas coortes.

Objective: To analyze the clinical characteristics of the severe or critically ill patients with novel coronavirus pneumonia (COVID-19), and evaluate the impact of complicated myocardial injury on the prognosis of these patients. Methods: A retrospective study was conducted in 54 patients who admitted to Tongji hospital from February 3, 2020 to February 24, 2020 and met the criteria of severe or critical conditions of COVID-19. The clinical characteristics and hospital mortality rate were analyzed and compared between the patients with or without myocardial injury, which was defined with 3 times higher serum cardiac troponin value. Results: The age of the 54 patients was 68.0(59.8, 74.3) years. Among all the patients, 24 (44.4%) patients were complicated with hypertension, 13 (24.1%) with diabetes, 8 (14.8%) with coronary heart disease, and 3 (5.6%) with previous cerebral infarction. During hospitalization, 24 (44.4%) of the patients were complicated with myocardial injury and 26 (48.1%) patients died in hospital. In-hospital mortality was significantly higher in patients with myocardial injury than in patients without myocardial injury (14 (60.9%) vs. 8 (25.8%), P=0.013). Moreover, the levels of C-reactive protein (153.6 (80.3, 240.7) ng/L vs. 49.8 (15.9, 101.9) ng/L) and N-terminal pro-B-type natriuretic peptide (852.0 (400.0, 2 315.3) ng/L vs. 197.0 (115.3, 631.0) ng/L) were significantly higher than patients without myocardial injury (all P<0.01). Conclusions: Prevalence of myocardial injury is high among severe or critically ill COVID-19 patients. Severe or critically ill COVID-19 patients with myocardial injury face a significantly higher risk of in-hospital mortality. The study suggests that it is important to monitor and manage the myocardial injury during hospitalization for severe or critically ill COVID-19 patients.

Objective: To analyze the prognostic value of myocardial injury in patients with COVID-19. Method: Confirmed cases of COVID-19 patients admitted from January 31st to February 5th at isolation ward of Renmin Hospital of Wuhan University were divided into non-survival group (33 cases)and survival group (169 cases)according to the clinical outcomes 5 weeks after admission. Data including demographics, comorbidities, vital signs, laboratory results were obtained. Cardiac injury was defined as serum concentration of high sensitivity cardiac troponin I (hs-cTnI) above 0.04 μg/L. Univariate and multivariate Cox regression were used to analyze the prognostic value of myocardial injury in patients with COVID-19. Kaplan-Meier analysis was used to plotted survival curve and analyze the impact of myocardial injury on the survival outcome of COVID-19 patients. Results: A total of 202 patients were included, the age was 63 (51, 70) years old, 88 (43.6%) of them were male, 85 (42.1%) of them had comorbidities, 125 (61.9%) of them were severely to critically ill. Till March 11, 33 patients died, all of them were critically ill patients. The age, proportion of males, comorbidities, respire rate, serum levels of hs-cTnI and incidence of heart failure in the non-survival group were significantly higher than those in the survival group (all P<0.05). The hospitalization time of non-survival group was significantly shorter than that of survival group (6(4, 9) vs. 32(23, 36), P<0.001). Myocardial injury was an important prognostic factor of COVID-19 (HR=5.382, 95%CI 2.404-12.050, P<0.001). Kaplan-Meier survival analysis showed that the presence of myocardial injury was significantly associated with the reduced survival rate among COVID-19 patients (P<0.001). Conclusion: Myocardial injury is an important prognostic factor of COVID-19, COVID-19 patients with myocardial injury face a significantly higher risk of death.

Because coronavirus disease 2019(COVID-19) is highly contagious and serious, it has posed a major threat to public health worldwide. The curative effects of integrated traditional Chinese medicine and Western medicine in the treatment of COVID-19 have been widely recognized and confirmed. However, medical workers shall pay attention to drug-induced heart injury in clinical application. Based on the guideline from the Diagnosis and Treatment Plans for COVID-19(trial seventh edition), taking the recommended drugs as examples, by Western medicine, traditional Chinese medicine, Chinese herbal injection and integrated traditional Chinese and Western medicine, the study analyzed the basic characteristics of recommended drugs for cardiac injury by means of literature review and bioinformatics methods, and summarized cardiac adverse reactions, toxicity mechanisms, combined pharmacotherapy, special population and drug monitoring, focusing on the clinical manifestations, toxic components, targets and regulatory mechanisms of drug-induced cardiac injury. The findings suggested being vigilant to drug-induced cardiac injury during the treatment of COVID-19, playing the advantages of clinical pharmacists and clinical Chinese pharmacists, improving the knowledge reserve of pharmacovigilance, strengthening the prescription review, medication notification and medication monitoring, promoting rational drug use and paying attention to special populations and high-risk groups. The study aims to provide suggestions and reference for pharmacovigilance and pharmaceutical care for front-line doctors and pharmacists against COVID-19, in order to avoid the occurrence of drug-induced heart injury for patients with COVID-19.
