[Complex management of intramural hematoma of the descending aorta: about a case]. / Manejo complejo del hematoma intramural de aorta descendente: a propósito de un caso.

Acute aortic syndromes (AAS) include a variety of overlapping anatomical and clinical conditions. Intramural hematoma (IMH), penetrating aortic ulcer, and aortic dissection occur in isolation or may coexist in the same patient. IMH represents 5-30% of all AAS and 60-70% of cases are located in the descending aorta. The diagnosis relies on a high index of clinical suspicion and on the use of complementary images. Management is conservative, but patients with some high-risk characteristics have a higher risk of mortality in the acute phase, so initial endovascular management should be considered. We present the case of a 69-year-old patient, in whom IMH was diagnosed in the course of a hypertensive emergency and who required hybrid management due to high-risk anatomical characteristics for endovascular management only.

Gender-related Differences in the Impact of COVID-19 Pandemic in Cardiometabolic Patients in Latin America: The CorCOVID LATAM Gender Sub-study.

COVID-19 pandemic and lockdown measures have disrupted lifestyle habits and self-care. Gender differences in health behavior during the pandemic have not yet been fully elucidated. The aim of this study was to evaluate gender related differences in the impact of COVID-19 pandemic on patients with cardiometabolic diseases. A cross-sectional survey was administered to cardiometabolic patients in 13 Latin American countries between June 15th and July 15th, 2020. The study included 4216 participants, of which 2147 (50.9%) were women. Women reported healthier eating habits as well as lower tobacco and alcohol consumption than men but exercised less and reported increased symptoms of depression. Low income and symptoms of depression were associated with sedentarism in women. The interplay between psychological factors and sedentarism could increase the risk of cardiovascular events in this population.

[Levels of 25 hydroxy vitamin D of serum and broncho-alveolar lavage in patients with pulmonary tuberculosis]. / Concentraciones de 25 hidroxi vitamina D séricas y en lavado bronco-alveolar en pacientes con tuberculosis pulmonar.

BACKGROUND: Alteration of vitamin D is a risk factor for tuberculosis (TB). AIM: To evaluate the pulmonary and serum levels of 25-hydroxy vitamin D (25OHD) in patients with and without pulmonary TB. METHODS: Two-stage study: the first part was retrospective cross-sectional and the second prospective. Those > 18 years of age who underwent fiberoptic bronchoscopy for suspected pulmonary TB and in whom the infection was confirmed were included. Patients with another type of infection without TB and non-infectious diseases were taken as controls for the first stage and infectious controls without TB in the prospective phase. The measurement of 25OHD was performed by ELFA (enzyme-linked fluorescence assay). The Kruskal-Wallis test was used to evaluate association, considering a value of p < 0.05 to be significant. The data were processed with the SPSS version 23 program. RESULTS: The total sample was 77 patients (35 in the first stage and 42 in the second). The characteristics between the groups were homogeneous. Serum (second phase) and broncho-alveolar lavage (first and second phase) levels of 25OHD were lower in TB patients compared to controls and were independent of serum calcium level (serum: 22.4 ng/mL vs 33 ng/mL, p = 0.006 and broncho-alveolar lavage: 9.7 ng/mL vs 12.2 ng/mL; p = 0.012). CONCLUSIONS: There was a significant difference between the levels of 25OHD in both serum and broncho-alveolar lavage in patients with pulmonary TB in relation to their controls.

Concentraciones de 25 hidroxi vitamina D séricas y en lavado bronco-alveolar en pacientes con tuberculosis pulmonar / Levels of 25 hydroxy vitamin D of serum and broncho-alveolar lavage in patients with pulmonary tuberculosis

INTRODUCCIÓN: La alteración de la vitamina D es un factor de riesgo para enfermar de tuberculosis (TBC). OBJETIVO: Evaluar la concentración pulmonar y sérica del compuesto 25-hidroxi-vitamina D (25OHD) en pacientes con y sin TBC pulmonar. METODOLOGÍA: Estudio de dos etapas: la primera parte fue de corte transversal, retrospectiva, y la segunda prospectiva. Se incluyeron > 18 años a los que se les realizó fibrobroncoscopia por sospecha de TBC pulmonar y en quienes se confirmó la infección. Se tomaron como controles a pacientes con otro tipo de infección no TBC, y enfermedades no infecciosas para la primera etapa y controles infecciosos sin TBC en la fase prospectiva. La medición de 25OHD se realizó mediante ELFA (ensayo de fluorescencia ligado a enzima). Se empleó la prueba de Kruskal-Wallis para evaluar asociación considerando significativo un valor de p < 0,05. Los datos se procesaron con el programa SPSS versión 23. RESULTADOS: La muestra total fue de 77 pacientes (35 en la primera etapa y 42 en la segunda). Las características entre los grupos fueron homogéneas. Las concentraciones en suero (segunda fase) como en el lavado bronco-alveolar (primera y segunda fase) de 25OHD fueron más bajas en pacientes con TBC comparado con los controles e independientes de la concentración de calcio sérico (suero: 22,4 ng/mL vs 33 ng/mL, p = 0,006 y lavado bronco-alveolar: 9,7 ng/mL vs 12,2 ng/mL; p = 0,012). CONCLUSIONES: Hubo una diferencia significativa entre las concentraciones de 25OHD, tanto en suero como en lavado bronco-alveolar, en pacientes con TBC pulmonar con relación a sus controles.

[Intra-aortic balloon counterpulsation placed through the subclavian artery as a bridge to heart transplantation. Case report]. / Balón de contrapulsación intraaórtico por acceso subclavio como puente a trasplante cardíaco. Reporte de casos.

Advanced heart failure is a major health problem for which heart transplantation or left ventricular assist devices are the only effective treatments. Intra-aortic balloon pump inserted using femoral artery access as a bridge to heart transplantation is still frequently used, but has the disadvantage of limiting the patient's movements, hence exposing him or her to the hazards of immobility and threatening the success of the procedure or hindering recovery. Access through the subclavian artery has become an attractive alternative since it doesn't impair the patient's mobility, and there is increasing evidence supporting its use. We present the first case of subclavian counterpulsation balloon implantation in a cardiovascular care center in Colombia.

Arterial lactate levels and their prognostic value in patients undergoing pulmonary thromboendarterectomy.

Objective: Evaluate the change of lactate levels and its prognostic role in the postoperative period of patients undergoing pulmonary thromboendarterectomy. Methods: Retrospective study between 2001 and 2019. Patients older than 18 years and who underwent pulmonary thromboendarterectomy were included. The U Mann Whitney test was performed to evaluate the change between lactate levels, and Cox regression analysis to evaluate the relationship with mortality. Areas under the curve were constructed for lactate levels. Results: Seventy-three patients were operated on during the study period. Median age was 51 years, 55% female. The median lactate on days 1 was 4.65 mml/L and on day 2 it was 1.62 mml/L with a change of 2.87 mml/L. No differences were found between the levels measured on day 1 and 2 between the people who died and those who did not on day 30. In the multivariate regression of COX, no relationship with mortality was found. The area under the curve shows regular performance on both day 1 and day 2 in predicting mortality outcomes. Conclusions: The behavior of the lactate in patients undergoing pulmonary thromboendarterectomy shows a rapid change during the first hours after the procedure. No role was found as a predictor of mortality neither in-hospital nor in follow-up.

Objetivo: Evaluar el cambio de los niveles de lactato y su rol pronóstico en el posoperatorio de pacientes sometidos a tromboendarterectomía pulmonar. Métodos: Estudio retrospectivo entre 2001 y 2019. Se incluyeron pacientes mayores de 18 años que fueron sometidos a tromboendarterectomía pulmonar. Para evaluar el cambio entre los niveles de lactato se realizó la prueba de U Mann Whitney. Para evaluar la relación con la mortalidad se realizó un análisis multivariado de Cox. Se construyeron áreas bajo la curva para los niveles de lactato. Resultados: . Setenta y tres pacientes fueron operados durante el período de estudio. La mediana de edad fue de 51 años, 55% mujeres. La mediana de lactato en el día 1 fue de 4,65 mmL/L y en el día 2 fue de 1,62 mmL/L con un cambio de 2,87 mmL/L. No se encontraron diferencias entre los niveles medidos el día 1 y 2 entre las personas que murieron y las que no al día 30 hospitalario. En la regresión multivariada de COX no se encontró relación con la mortalidad. El área bajo la curva muestra un desempeño regular tanto en el día 1 como en el día 2 para predecir el resultado de la mortalidad en especial intrahospitalaria. Conclusiones: El comportamiento del lactato en pacientes sometidos a tromboendarterectomía pulmonar muestra un cambio rápido durante las primeras horas posteriores al procedimiento. No se encontró que sea un predictor de mortalidad ni hospitalaria ni durante el seguimiento.

Impacto de COVID-19 en la enfermedad cardiovascular / Impact of COVID-19 on cardiovascular disease

Resumen La enfermedad por coronavirus-2019 (COVID-19) es una enfermedad infecciosa cuya sintomatología inicial, en la mayoría de las ocasiones, se manifiesta con compromiso del tracto respiratorio. El virus que causa dicha enfermedad se denomina síndrome respiratorio agudo severo por coronavirus 2 (SARS-CoV2). Si bien la manifestación grave más frecuente de la infección parece ser la neumonía, se han documentado diversas implicaciones cardiovasculares. Las personas que cursan con dicha infección y que tienen una enfermedad cardiovascular preexistente tienen un riesgo mayor de cuadros graves y mortalidad. Existen asociaciones directas o indirectas de la infección con injuria miocárdica, arritmias, enfermedad tromboembólica venosa y miocarditis. Los tratamientos en investigación pueden tener efectos adversos en el sistema eléctrico del corazón; además, algunos medicamentos de uso crónico (como los inhibidores del sistema renina angiotensina aldosterona) se les ha otorgado un polémico papel en la virulencia del microorganismo. La alta demanda en atención en salud que requieren los pacientes infectados por SARS-CoV 2 puede comprometer la asistencia de pacientes cardiovasculares sin dicha infección y dejar en riesgo de exposición al personal sanitario. Se presenta una revisión sobre los aspectos más llamativos donde estas dos condiciones interaccionan.

Abstract Coronavirus-2019 disease (COVID-19) is an infectious disease which initial symptoms, in most cases, manifest with respiratory tract compromise. The virus that causes said disease is called severe acute respiratory syndrome by coronavirus 2 (SARS-CoV 2), although the most frequent serious manifestation of the infection appears to be pneumonia, various implications have been documented from the cardiovascular point of view. People who have this infection and a pre-existing cardiovascular disease have an increased risk of severe symptoms and mortality. There are direct or indirect associations of the infection with myocardial injury, arrhythmias, venous thromboembolic disease and myocarditis. Investigational treatments may have adverse effects on the heart's electrical system. In addition, some medications of chronic use (such as renin angiotensin aldosterone systeminhibitors), have been given a controversial role in the virulence of the organism. The high demand in health care required by patients infected with SARS-CoV 2 can compromise the care of cardiovascular patients without said infection, in addition to leaving healthcare personal at risk of exposure. Therefore, a review is presented on the most striking aspects where these two conditions interact.

Aneurisma de arteria pulmonar: un hallazgo incidental / Pulmonary artery aneurysm: an incidental finding

Resumen Los aneurismas de la arteria pulmonar son entidades infrecuentes y su tratamiento es tema de discusión. Desde el punto de vista etiológico pueden ser congénitos o adquiridos. Los primeros, generalmente se asocian a malformaciones cardiacas que producen hipertensión pulmonar, siendo el ductus arterioso la más frecuente. Otras anomalías incluyen defectos auriculares o ventriculares. Las causas adquiridas pueden ser idiopáticas o estar asociadas a infecciones (tuberculosis, sífilis), traumatismos o colagenopatías. Presentamos el caso de una mujer de 62 años, quien consultó por un cuadro clínico en el que se destacaba su sintomatología neurológica e infecciosa, con posterior progresión a un choque séptico y en quien los hallazgos de las imágenes mostraron un aneurisma gigante de la arteria pulmonar siendo este un hallazgo incidental y sin relación a la sintomatología de la paciente.

Abstract Aneurysms of the pulmonary artery are rare entities and their treatment is a matter of discussion. From the etiological point of view, they can be congenital or acquired. Those in the first group are generally associated with cardiac malformations that generate pulmonary hypertension, with the ductus arteriosus being the most frequent. Other abnormalities include atrial or ventricular defects. The acquired causes may be idiopathic or associated with infections (tuberculosis, syphilis), trauma, or collagen disease. We present the case of a 62-year-old woman, which consulted for a clinical condition where neurological and infectious symptoms stood out, with subsequent progression to a state of septic shock, and in whom the imaging finding showed a giant pulmonary artery aneurysm. this being an incidental finding and unrelated to the patient's symptoms.

[Coronary chronic total occlusion and bifurcation lesions, lessons from contemporary management: case report]. / Oclusión crónica total coronaria y lesiones en bifurcaciones, lecciones del manejo contemporáneo: reporte de caso.

Coronary artery disease involving chronic occlusions and bifurcation lesions continues to be a challenge for the interventional cardiologist. The improvement in the techniques has allowed a higher success rate, however, the best intervention strategy is unknown in this subgroup of patients with chronic occlusions and associated bifurcation lesions. We present the case of a patient in whom, in an angiography for study of chest pain, a chronic total occlusion and a bifurcation lesion were evidenced and were successfully treated by coronary intervention.

Abstract Objective: To describe the findings in the study of bone marrow of patients with human immunodeficiency virus (HIV) infection who present some type of cytopenia in a highly complex hospital in southern Colombia. Materials and methods: Retrospective descriptive study of case series. All adult pa tients with confirmed HIV infection who presented some type of cytopenia during January 2011 to December 2014 at the University Hospital Hernando Moncaleano Perdomo de Neiva, were included. A total of 37 patients com pleted the inclusion criteria. Results: the median age was 35 years, 59 % men; in 48.6 % of the individuals, the time of diagnosis by HIV was less than one year and 59 % did not receive antiretroviral therapy at the time of admission. A median was found in a leukocyte count of 2400 cells / mm3, neutrophils of 1400 cells / mm3, CD4 lymphocytes of 43 cells / mm3. The bone marrow study was positive in 27 % of the cases (10 patients), finding disseminated opportunistic infection in six patients; two neoplasms, plus a medullar hypoplasia and a case of megaloblastic anemia. Conclusion: The study of bone marrow in patients with HIV infection is a useful tool and should be performed in all patients with HIV infection with advanced disease in the study of cytopenia associated or not with fever.

Hallazgos clínicos, ecocardiográficos y electrocardiográficos en donantes de sangre seropositivos para Trypanosoma cruzi en un centro de referencia del sur de Colombia / Clinical, cardiac ultrasonography, and electrocardiographic findings in blood donors who were found to be seropositive for Trypanosoma cruzi infection in a reference center in southern Colombia

Objetivo: Evaluar las características clínicas y hallazgos electrocardiográficos como de ecocardiografía en pacientes quienes tenían una serología positiva en el banco de sangre de un centro de referencia del sur de Colombia. Material y métodos: Estudio descriptivo, de corte transversal, en el que se analizaron todos los eventos de donación del banco de sangre del Hospital Universitario Hernando Moncaleano Perdomo, de Neiva Huila Colombia, en un periodo comprendido entre enero del 2011 hasta diciembre de 2014. Fueron incluidos pacientes mayores de 18 años, con serología IgG por ELISA positiva para Trypanosoma cruzi, posteriormente confirmada por detección de IgG por inmunofluorecencia indirecta. Se les realizó anamnesis clínica, examen físico, ecocardiogramas transtorácicos y monitoreos electrocardiográficos de ritmo cardiaco 48 durante horas. Resultados: Se registraron 41 865 donantes en el banco de sangre, la prevalencia de infección por T. cruzi fue de 0,15%, promedio de edad 47,8 años, 68,42% de género masculino y la mayoría de zona urbana. Un porcentaje importante de los pacientes manifestó alguna sintomatología relacionada con cardiopátia chagásica. Además la mayoría presentó compromiso de la fracción de inyección del ventrículo izquierdo (leve a moderado) y en la totalidad se detectó alguna anormalidad electrocardiográfica. Conclusión: El hallazgo en el índice de variabilidad de la frecuencia cardíaca se debería considerar como un posible indicador importante en esta patología, en cuanto al reconocimiento temprano antes de notar alteraciones estructurales que generen una falla cardíaca sintomática en esta patología

Objective: This study aimed to assess the clinical characteristics and the electrocardiographic and cardiac ultrasonography findings in patients who had positive serology test results for Chagas' disease in a reference center in southern Colombia. Materials and methods: This is a descriptive, cross-sectional study in which we assessed all blood donating events in the blood bank of the Hernando Moncaleano-Perdomo Hospital in Neiva Huila, Colombia, from January, 2011 to December, 2014. Patients more than 18 years old who had positive results in the serum IgG measurement for Trypanosoma cruzi, which had to be confirmed afterwards using indirect immunofluorescence for IgG detection. The patients had a medical history taken, they underwent physical examination, transthoracic cardiac ultrasonography, and electrocardiographic continuous 48-hour monitoring. Results: Nearly forty-two thousand (41,865) blood donors were recorded in the blood bank. The prevalence of T. cruzi infection was 0.15%, the average age of the subjects was 47.8 years, two thirds (68.42%) were male, and most came from urban areas. An important proportion of patients presented with some symptoms related to Chagas' disease cardiopathy, most had alterations in the left ventricular ejection fraction and all of them showed at least one electrocardiographic abnormality. The finding in the index of heart rate variability should be considered as a possible early indicator in this pathology, before the presence of structural alterations that could generate a symptomatic heart failure
