Epidural Hematoma Associated with Red Clover Use After Epidural Injection: A Case Report.

An epidural hematoma is a rare but devastating complication after interventional pain procedures. The etiology is multifactorial, including anatomical variations, inherited coagulation disorders, and consumption of anticoagulants or antiplatelet substances. Specifically, in regard to platelet aggregation, the consumption of herbal medicine is often forgotten as a potential cause for coagulation profile disorders, potentially leading to an epidural hematoma. We present the case of a patient who developed an epidural hematoma after a cervical epidural block, most likely associated with daily "red clover" consumption.

Clinical and hemodynamic outcomes and mortality risk factors in patients undergoing pulmonary thromboendarterectomy.

BACKGROUND: Pulmonary thromboendarterectomy is the current treatment of choice in patients with chronic thromboembolic pulmonary hypertension. The objective of the present study was to analyze the clinical and hemodynamic outcomes and the risk factors for mortality in a cardiovascular center in Colombia. METHODS: Cohort study, conducted between 2001 and 2019. All operated patients were included in the study. Risk factors associated with mortality were established by means of a multivariate regression using the COX method and survival was established using the Kaplan-Meier method. p < 0.05 was considered statistically significant. RESULTS: Seventy-three patients were operated. Median age was 51 years, 55% of females, 79% had functional Class III and IV. The mean pulmonary arterial pressure was 50 mmHg and 640 dyn.s.cm-5 for pulmonary vascular resistance (PVR). After the intervention, there was a decrease in mean pulmonary artery pressure (p ≤ 0.001) and in PVR (p = 0.357); 21% had evidence of residual pulmonary hypertension. Only 8% and 6% continued with functional Class III and IV at 6 and 12 months, respectively. There were 15 deaths (19.1%; 12% at 30 days). The factors associated with mortality were the diastolic diameter of the right ventricle measured postoperatively (hazard ratio [HR] 10.88 95% confidence interval [CI] 1.97-62, p = 0.007), time of invasive mechanical ventilation (HR 1.06 95% CI 1.02-1.09 p = 0.004), and the presence of complications during the surgical procedure (HR 5.62 95% CI 1.94-16.22 p = 0.001). CONCLUSIONS: Pulmonary thromboendarterectomy is associated with excellent clinical and hemodynamic outcomes. The mortality risk factors found are not those usually described in the literature.

Characterization of Risk Factors for Neural Tube Defects: A Case-Control Study in Bogota and Cali, Colombia, 2001-2018.

Worldwide prevalence of neural tube defects is between 1.2 and 124.1 per 10 000 live births. This study analyzes risk factors linked with neural tube defects. The study focused on the Surveillance and Monitoring Programs of Congenital Anomalies databases in Bogota and Cali. Births were monitored between 2001 and 2018. Liveborn or stillborn with neural tube defects were defined as cases, using a case-control ratio of 1:4. Paternal age, folic acid supplementation, birth weight, urban or rural origin, maternal and paternal studies, and socioeconomic levels were analyzed. Across the 215 730 births monitored, 147 cases with a rate of 6.82/10 000 live births were found (6.79-6.85). In isolated cases, lower birth weight had a P <.01. Paternal age >45 years showed an odds ratio (OR) of 4.24 (1.54-11.65), socioeconomic status 1 and 2, OR of 2.49 (1.63-3.82), maternal primary schooling or lower OR 2.61 (1.28-5.31), and housing in urban areas OR 2.4 (1.4-4.09).

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.

[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.

[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.

[Heart Failure With Preserved Ejection Fraction: A Problem Of Contemporary Cardiology]. / Falla Cardíaca con Fracción de Eyección Preservada: Un Problema de la Cardiología Contemporánea.

Heart failure with preserved ejection fraction (HFpEF) is a frequent and overlooked medical condition that represents a great challenge for diagnosis and treatment. Current data shows a temporal trend towards a higher prevalence of HFpEF, even above heart failure with reduced ejection fraction (HFrEF). The pathophysiology of HFpEF is heterogeneous and involves several factors such as genetics, lifestyle, and cardiac and non-cardiac comorbidities. These factors result in remodeling, maladaptation and cardiac stiffness, that later on cause dyspnea, exercise intolerance, and fatigue. Although the mortality outcome of HFpEF is as high as HFrEF, no specific therapy has demonstrated overall benefit in these patients; which is why future therapies will bet on an individualized approach according to the patients phenotype.

Resumen Antecedentes: La tromboendarterectomía pulmonar es el tratamiento de elección actual en pacientes con hipertensión pulmonar tromboembólica crónica. El objetivo del presente estudio fue analizar los resultados clínicos y hemodinámicos y los factores de riesgo de mortalidad en un centro cardiovascular de Colombia. Métodos: Estudio de cohorte entre 2001 y 2019. Se incluyeron todos los pacientes operados. Los factores de riesgo asociados a la mortalidad se establecieron mediante una regresión multivariante mediante el método COX y la supervivencia se estableció mediante el método de Kaplan-Meier. Los valores de p < 0.05 se consideraron estadísticamente significativos. Resultados: se operaron 73 pacientes. La mediana de edad fue de 51 años, 55% mujeres, 79% tenían clase funcional III y IV. La presión arterial pulmonar media fue de 50 mmHg y 640 dyn.s.cm−5 para la resistencia vascular pulmonar. Después de la intervención, hubo una disminución en la presión arterial pulmonar media (p ≤ 0.001) y en la resistencia vascular pulmonar (p = 0.357). El 21% tenía evidencia de hipertensión pulmonar residual. Solo el 8% y el 6% continuaron con clase funcional III y IV a los 6 y 12 meses respectivamente. Hubo 15 muertes (19.1%; 12% a los 30 días). Los factores asociados con la mortalidad fueron el diámetro diastólico del ventrículo derecho medido en el postoperatorio (HR 10.88 IC 95% 1.97-62, p = 0.007), el tiempo de ventilación mecánica invasiva (HR 1.06 IC 95% 1.02-1.09 p = 0.004) y el presencia de complicaciones durante el procedimiento quirúrgico (HR 5.62 IC 95% 1.94-16.22 p = 0.001). Conclusiones: La tromboendartectomía pulmonar se asocia con excelentes resultados clínicos y hemodinámicos. Los factores de riesgo de mortalidad encontrados no son los habitualmente descritos en la literatura.

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.
