In-stent chronic total occlusion angioplasty in the LATAM-CTO registry.

OBJECTIVES: To inform about contemporary PCI practice of in-stent (IS) chronic total occlusions (CTO) from a large international registry in Latin America. BACKGROUND: IS-CTO represent a distinctive challenge for PCI, but literature is limited and restricted to high-resource regions of the world. METHODS: Patients undergoing CTO PCI enrolled in the LATAM CTO registry from 42 centers in eight countries were included. We analyzed demographics, angiographic, procedure technique, success and postprocedural outcomes between IS-CTO and non-IS-CTO PCI. RESULTS: From 1,565 patients IS-CTO was present in 181 patients (11.5%). IS-CTO patients had higher prevalence of diabetes and hypertension than patients without IS-CTO. IS-CTOs had less calcification (32.5 vs. 46.7%, p < .001), lower prevalence of a proximal branch (36.3 vs. 50.1%, p < .001), more likely to be ostial (24.4 vs. 18.1%, p = .042), were longer (28.5 vs. 25.2 mm, p = .062), and had less interventional collaterals (49.1 vs. 57.3%, p = .038) compared with non-IS-CTO. CTO complexity scores were similar between both groups. There was no statistically significant difference in the initial or successful strategy between IS-CTO and non-IS-CTO PCI. Technical success rates remained high in IS-CTO (86.7%) and non-IS-CTO (83.1%, p = .230). There was no independent association between IS-CTO and technical success in multivariable analysis. There were no differences between IS-CTO and non-IS-CTO groups for in-hospital clinical outcomes. CONCLUSION: In a contemporary, multicenter, and international registry from Latin America, IS-CTO PCI is frequent and has comparable technical success and safety profile compared to non-IS-CTO PCI.

Registro multicéntrico prospectivo de pacientes hospitalizados por síndrome coronario agudo sin elevación del segmento ST en centros de alta complejidad. Resultados intrahospitalarios y evolución a 6 meses (Buenos Aires I) / Prospective multicenter registry of patients hospitalized for acute coronary syndrome without ST segment elevation in highly complex centers

RESUMEN Introducción: El manejo de los síndromes coronarios agudos (SCA) sin elevación del segmento ST (SCASEST) ha presentado cambios en los últimos años, basados en nuevos agentes farmacológicos y en el avance de las técnicas de revascularización coronaria. El objetivo de este estudio fue determinar cómo es el manejo de los SCASEST en la actualidad, en centros de alta complejidad de la ciudad de Buenos Aires y la provincia de Buenos Aires. Métodos: Se registraron en forma prospectiva pacientes hospitalizados en 21 centros con servicio de unidad coronaria, hemodinamia disponible las 24 horas y cirugía cardíaca. Se realizó seguimiento a 6 meses del alta hospitalaria. Resultados: Se incluyeron 1 100 pacientes consecutivos; el 62,6% fue catalogado como infarto sin elevación del ST y, 37,4% como angina inestable. La edad media fue de 65,4 ± 11,5 años, con el 77,2% de sexo masculino. El 27,6% presentaba diabetes mellitus y el 31,5% infarto previo. El manejo inicial fue invasivo en el 86,7%, con una mediana de tiempo a la cinecoronariografía de 18 horas (RIC 7-27,7). En la evolución intrahospitalaria, la incidencia de nuevo infarto fue del 5,2%, el accidente cerebrovascular de 0,3% y la mortalidad total, 2,7%. La tasa de sangrado BARC ≥2 fue del 10,1%. En el seguimiento extrahospitalario a los 6 meses del alta hospitalaria, la tasa de infarto fue de 8,4%, SCA 10,9% y la mortalidad total de 5,7%. Conclusiones: El registro evidenció un abordaje terapéutico predominantemente invasivo de los pacientes con SCASEST en los centros con alta complejidad, con baja prevalencia de complicaciones intrahospitalarias y en la evolución.

ABSTRACT Introduction: The medical management of acute coronary syndromes (ACS) has changed significantly over the past few decades, primarily due to novel pharmacotherapies and improvement in coronary revascularization strategies. This registry was compiled from data from management of patient populations in high complexity centers from Buenos Aires, Argentina. Methods: Patients hospitalized in 21 centers in the city of Buenos Aires and peripheries, with a coronary unit service, hemodynamics available 24 hours and cardiac surgery are prospectively registered. Follow-up was performed at 6 months. Results: A total of 1100 patients were included; the final diagnosis was myocardial infarction in 62.% and unstable angina in 37.4%. The mean age of the population was 65.4 ± 11.5 and 77.2% were male. 27.6% of patients having diabetes mellitus, with 31.5% having a medical history of myocardial infarction. The initial management was invasive in 86.7%, with a median time for PCI of 18 hours (IQR 7-27,7). Over the course of the in-hospital stay, the rate of myocardial infarction was 5.2%, stroke 0.3% and total all-cause mortality 2.7%. The rate of in-hospital total bleeding events was 20.1%, with BARC ≥2 in 10.1% of patients. In the 6-month follow-up, the infarction rate was 8.4%, ACS 10.9%, and total mortality 5.7%. Conclusions: This registry shows the predominant usage of invasive approaches in management of patients with acute coronary syndrome without ST elevation, in high complexity medical centers. In this subset of patients, a low rate of in-hospital and follow up complications were also observed.

Coeficiente de Adversidad en aspirantes a soldados del Ejército Ecuatoriano / Adversity quotient in training soldier staff of the Ecuadorian Army

Introducción: Coeficiente de Adversidad (Adversidad Quotient ® - AQ, en su versión original en inglés), es el producto más robusto y método ampliamente utilizado en el mundo para medir la resiliencia humana. Objetivo: determinar el Coeficiente de Adversidad en aspirantes a soldados del ejército. Método: se ejecutó una revisión del estado de la cuestión lo que llevó a adoptar las bases teóricas que sustentan el estudio. Metodológicamente fue de tipo transeccional, descriptivo de campo, teniendo como población 1 227 aspirantes a soldados y una muestra total de 332 unidades de información correspondientes a 10 pelotones seleccionados al azar, de los dos cursos académicos. El instrumento utilizado para la recolección de información fue el Coeficiente de Adversidad, compuesto por 75 ítems, los cuales evaluaron los factores control, propiedad, alcance y duración, así como determinaron el Coeficiente de Adversidad terreno de la muestra estudiada. Resultados: los más importantes permiten reportar, que el personal posee altos niveles de control, Propiedad y Duración, en referencia al Alcance, el nivel también es alto pero en menor medida que los anteriores. Conclusiones: en términos generales la muestra posee un alto nivel de coeficiente de adversidad(AU)

Introduction: Adversity Quotient®, is the most robust product and method widely used in the world to measure human resilience. Objective: To set the Adversity Quotient, in the Army future soldiers. Method: A review of the state of the issue was carried out, which led to the adoption of the theoretical bases that support the study. The methodology was of the field trans-sectional type, having 1227 candidates for future soldiers and a total sample of 332 units of information corresponding to 10 platoons selected at random, from two academic courses. The instrument used for data collection was the Adversity Quotient, composed of 75 items, which evaluated the factors Control, Property, Scope and Duration, as well as determined the field Adversity Quotient of the sample studied. Results: The most important results allows to report that the personnel has high levels of Control, Property and Duration, in reference to the Scope the level is also high but in a lower average to the previous ones. Conclusion: In general terms the sample has a high level of adversity coefficient(AU)
