RESUMO

Background: ST-elevation myocardial infarction (STEMI) requires revascularization treatment, preferably via primary percutaneous coronary interventions (pPCI). There is a lack of data about contemporary management of STEMI in Latin America. Methods: This was a multicenter, multinational, prospective, and dynamic registry of patients undergoing pPCI in Latin America for STEMI (STEMI/LATAMI Registry) that was carried out in nine centers from five countries (Argentina, Ecuador, Venezuela, Bolivia, and the Dominican Republic) between June 2021 and June 2023. All interventionalists involved in the study were originally trained at the same institution (Centro de Estudios en Cardiología Intervencionista, Buenos Aires, Argentina). The primary objective was to evaluate procedural and in-hospital outcomes of pPCI in STEMI and in-hospital outcome in the Latin America (LATAM) region; as secondary endpoints, we analyzed the following subgroups: differences between pPCI vs. pharmaco-invasive or late presenters, gender, elderly and very elderly patients, cardiogenic shock outcomes, and causes of STEMI. Results: In total, 744 STEMI patients who underwent PCI between June 2021 and June 2023 in five countries (nine centers) in our continent were included; 76.3% had a pPCI, 8.1% pharmaco-invasive PCI, and 15.6% had late STEMI PCI. There were no differences in region or center when we evaluated in-hospital and 30 days of death. The rate of procedural success was 96.2%, and the overall in-hospital mortality rate was 2.2%. In the subgroup of pPCI, mean symptom onset-to-balloon time was 295.3 ± 246 min, and mean door-to-balloon time was 55.8 ± 49.9 min. The femoral approach was chosen in 60.5%. In 3.0% of patients, the left main disease was the culprit artery, with 1.63 ± 1.00 stents per patient (564 drug-eluting stents and 652 bare metal stents), with 34 patients receiving only plain optimal balloon angioplasty. Definitive stent thrombosis was related to the infarct artery as the primary cause of STEMI in 7.5% of patients. The use of assistant mechanical devices was low, at 2.1% in the pPCI group. Women were older, with large numbers in very elderly age (≥90 years), greater mortality, and incidence of spontaneous coronary dissection as a cause of STEMI (p < 0.001, p < 0.001, p < 0.001, and p < 0.003, respectively). Conclusion: In suitable LATAM Centers from low/medium-income countries, this prospective registry in patients with STEMI, PCI performed by well-trained operators has comparable results to those reported in well-developed countries.

RESUMO

Fabry disease is an invalidating multisystemic disorder affecting α-Galactosidase, a rate-limiting hydrolase dedicated to lipid catabolism. Non-metabolized substrates, such as Globotriaosylceramide and its derivatives trigger the direct or indirect activation of inflammatory events and endothelial dysfunction. In spite of the efficacy demonstrated by enzyme replacement therapy or pharmacological chaperones in delaying disease progression, few studies have analyzed whether these treatments can improve the pro-inflammatory state of FD patients. Therefore, the aim of this work was to assess cytokines and cardiovascular risk-related proteins detectable in plasma from FD patients, whether treated or not with ERT, to evaluate the reliability of these markers in monitoring disease stage and treatment effects. We identified inflammatory and endothelial dysfunction markers (ADAMTS-13, TNF-α, GDF-15, MIP-1ß, VEGFA, MPO, and MIC-1) that cooperate in a common pathway and are increased in FD patients' plasma samples. As shown by the assessment of these proteins over time, they can help to evaluate the risk of higher severity in FD, as well as ERT effects. Even though the analyzed proteins cannot be considered as proper biomarkers due to their non-specificity to FD, taken together they can provide a signature of reference molecules with prognostic value for early diagnosis, and evaluation of disease progression and treatment efficacy, using blood samples.

RESUMO

Introduction: Bipolar disorder (BD) is a recurrent and disabling psychiatric disorder related to low-grade peripheral inflammation and altered levels of the members of the insulin-like growth factor (IGF) family. The aim of this study was to evaluate the plasma levels of IGF-2, insulin-like growth factor-binding protein 1 (IGFBP-1), IGFBP-3, IGFBP-5, IGFBP-7, and inflammatory markers such as tumor necrosis factor α (TNF-α), monocyte chemoattractant protein 1 (MCP-1), and macrophage inflammatory protein 1ß (MIP-1ß). Methods: We used the Young Mania Rating Scale (YMRS) to determine the severity of the symptomatology, while proteins were measured by enzyme-linked immunosorbent assay (ELISA). We included 20 patients with BD who suffered a manic episode and 20 controls. Some BD patients (n = 10) were evaluated after a period (17 ± 8 days) of pharmacological treatment. Results: No statistical difference was found in IGF-2, IGFBP-1, IGFBP-7, TNF-α, and MIP-1ß levels. However, IGFBP-3 and IGFBP-5 levels were found to be statistically decreased in BD patients. Conversely, the MCP-1 level was significantly increased in BD patients, but their levels were normalized after treatment. Intriguingly, only IGFBP-1 levels were significantly decreased after treatment. No significant correlation was found between the YMRS and any of the proteins studied either before or after treatment or between IGF proteins and inflammatory markers. Discussion: To some extent, IGFBP-3 and IGFBP-5 might be further explored as potential indicators of treatment responsiveness or diagnosis biomarkers in BD.

RESUMO

Introducción En el Registro CONAREC V, de 1996, se recopilaron los resultados obtenidos con angioplastia transluminal coronaria (ATC) y posteriormente, durante 2005, se recabaron datos con similar metodología generándose el Registro CONAREC XIV. Desde entonces no se cuenta con datos nacionales generales en relación con la revascularización coronaria percutánea, por lo que la Sociedad Argentina de Cardiología, en conjunto con el CACI, la FAC y el CONAREC, implementó el Registro Argentino de Angioplastia Coronaria (RAdAC). Objetivo Evaluar a escala nacional los resultados intrahospitalarios y la morbimortalidad de pacientes sometidos a ATC según los distintos escenarios clínicos. Material y métodos En un período de 7 meses se incluyeron 1.905 pacientes en forma prospectiva y consecutiva en 67 centros de la Argentina. Se analizaron factores de riesgo, antecedentes cardiovasculares y cuadro clínico. La ATC se consideró programada, de urgencia y de emergencia, y se estimó el número de vasos enfermos y la intención de vasos a tratar y la cantidad y tipo de stents convencionales (SC) y liberadores de droga (SLD);. Se analizó el empleo de aterectomía, Cutting Balloon®, tromboaspiración, ultrasonido intravascular (IVUS), antiagregantes y balón de contrapulsación intraaórtico (BCIA). El éxito angiográfico se definió como lesión residual < 20% y flujo normal (TIMI 3). Resultados La edad promedio fue de 63,8 años. Un total de 752 pacientes (39,5%) presentaban infarto agudo de miocardio (IAM) y 834 pacientes (43,8%) angina inestable (AI). Se utilizó acceso femoral en el 92,8% de los casos. El 44,3% de las intervenciones fueron programadas, el 37,8%, de urgencia y el 17,9%, de emergencia. Se implantaron 2.753 stents (1,4 por paciente) con 33,2% de SLD. El éxito primario fue del 97% y la mortalidad global observada, del 1,6%; la asociada con infarto ascendió al 3,2% (con ST 4,3%, sin ST 1,7%), la de AI fue del 0,8% y la de angina crónica estable, del 0,3%. Las variables asociadas con el óbito fueron shock cardiogénico, necesidad de BCIA, Killip y Kimball 3-4, ATC de emergencia, ATC del tronco, mala función ventricular, insuficiencia renal o diabetes, mayor número de vasos enfermos, mayor edad y fracaso de la ATC. Conclusiones En nuestro medio, la mayoría de las ATC se realizan en síndromes coronarios agudos y casi exclusivamente por vía femoral, con éxito primario comparable a datos internacionales pero con menor utilización de SLD. El empleo de Rotablator®, Cutting Balloon®, tromboaspiración, IVUS y BCIA fue más bajo que el esperado, mientras que la edad, el shock cardiogénico, la emergencia y la ATC fallida resultaron factores asociados con mayor morbimortalidad.


Background Percutaneous transluminal coronary angioplasty (PTCA) outcomes were compiled in the 1996 V CONAREC Registry, and in 2005, data collection was repeated using a similar methodology, giving rise to the XIV CONAREC Registry. As no general national PTCA results have been reported since, the Argentine Society of Cardiology, together with CACI, FAC and CONAREC carried out the Coronary Angioplasty Argentine Registry (RAdAC). Objective The aim of this Registry was to evaluate intrahospital outcome and morbi-mortality of patients submitted to PTCA according to different clinical scenarios. Methods One thousand nine hundred and five patients were prospectively and consecutively included in 67 centers of Argentina during a 7-month period. Cardiovascular risk factors and clinical history were analyzed. PTCA procedures were classified as: planned, urgent or emergent and the number of affected and intended-to-treat vessels, as well as the number and type of stents implanted bare metal (BMS) or drug-eluting stents (DES); were estimated. Use of atherectomy, Cutting Balloon?, thrombus aspiration, intravascular ultrasound (IVUS), antiplatelet drugs and intra-aortic balloon pump (IABP) was analyzed. Angiographic success was defined as residual lesion <20% and normal flow (TIMI 3). Results Mean age was 63.8 years. A total of 752 patients (39.5%) presented with acute myocardial infarction (AMI) and 834 patients (43.8%) with unstable angina (UA). Femoral access was used in 92.8% of the cases. Overall, 44.3% of the interventions were planned, 37.8% were urgent and 17.9% emergent. A total of 2753 stents were implanted (1.4 per patient), 33.2% of which were DES. The primary success rate was 97% and overall mortality 1.6%: 3.2% associated to AMI, (4.3% STEMI and 1.7% non-STEMI), 0.8% to UA and 0.3% to chronic stable angina. Death-associated variables were: cardiogenic shock, need of IAPB, Killip-Kimball class 3-4, emergency PTCA, left main PTCA, ventricular function impairment, renal failure or diabetes, number of affected vessels, age and PTCA failure. Conclusions In our setting, most PTCAs are performed in acute coronary syndromes, almost exclusively by femoral access, with primary success comparable to that of international reports, but employing less DES. Use of Rotablator, Cutting Balloon?, thrombus aspiration, IVUS and IABP implementation was lower than expected, while age, cardiogenic shock, emergency and PTCA failure were factors associated with increased morbi-mortality.

RESUMO

La tromboembolia de pulmón es una patología cardiovascular frecuente, con una incidencia de 1/1.000 en los Estados Unidos y una mortalidad que alcanza el 15% en los tres meses siguientes a su diagnóstico. Esta mortalidad aumenta cinco veces en los pacientes que desarrollan shock. A pesar de su incidencia y morbimortalidad elevadas, el tratamiento habitual no ha variado sustancialmente en los últimos años y aun a pesar de los avances en las terapias con trombolíticos o la endarterectomía quirúrgica, la tasa de mortalidad se mantiene muy elevada en los pacientes con tromboembolia pulmonar masiva. Recientemente se ha comenzado a utilizar terapias de trombectomía percutánea, que abren una nueva opción terapéutica que debe considerarse si se dispone de los medios necesarios. En esta presentación se describen dos casos de tromboembolia pulmonar masiva tratados con trombectomía reolítica.


Pulmonary embolism (PE) is a common cardiovascular disease with an incidence of 1/1000 in the United States and a mortality rate of 15% three months after been diagnosed. Mortality is five times greater in patients with shock. Despite its high incidence, morbidity and mortality, the treatment has not varied in the last years, and in patients with massive PE mortality still remains high even with the current improvements in thrombolytic therapy or surgical endarterectomy. The recent introduction of percutaneous thrombectomy techniques has opened a new therapeutic option that should be considered when available. We describe two case reports of massive pulmonary embolism treated with rheolytic thrombectomy.

RESUMO

Objetivo: Evaluar la precisión diagnóstica de la angiografía coronaria por tomografía computarizada multislice (ACTCM) para la detección de estenosis significativas en arterias coronarias. Material y métodos: Se estudiaron pacientes con indicación de cinecoronariografía diagnóstica sin antecedentes de alergia al contraste, insuficiencia renal ni arritmias. Para la adquisición de imágenes se utilizó un tomógrafo multislice (multicorte) (Brilliance 40, Philips, The Netherlands) gatillado electrocardiográficamente. Se administraron 90-125 ml de contraste yodado por vía endovenosa. La obesidad, la diabetes, los segmentos difusamente calcificados, con diámetro < 2,0 mm, y aquellos tratados con stents no constituyeron criterios de exclusión. Las lesiones se definieron significativas cuando presentaron una reducción luminal ≥ 50 por ciento por ACTCM y angiografía cuantitativa coronaria (QCA). Resultados: Previo a la intervención se escanearon 38 pacientes. De ellos, uno (3 por ciento) fue excluido debido a calidad de imagen insuficiente. Los 37 restantes (444 segmentos), con calidad de scan satisfactoria, se incluyeron en el estudio (81 por ciento hombres, edad media 62,43 ± 12,5 años, 13,5 por ciento diabéticos). El tiempo medio de scan fue de 15,12 ± 2,6 segundos. Se analizaron 444 segmentos por ambas técnicas. Se encontraron 88 (17 por ciento) y 93 (18 por ciento) lesiones significativas por CCG y ACTCM, respectivamente. La sensibilidad, la especificidad, el valor predictivo positivo y el valor predictivo negativo de la ACTCM para detectar estenosis significativas fueron del 82 por ciento, 93 por ciento, 72 por ciento y 96 por ciento, respectivamente. Conclusión: En pacientes seleccionados para cinecoronariografía, la angiografía coronaria por tomografía computarizada multislice presenta un alto valor predictivo negativo para la detección de enfermedad obstructiva coronaria.

RESUMO

La lesión de tronco no protegido fue la primera lesión coronaria tratada con revascularización miocárdica con by pass-aortocoronario y en el seguimiento a largo plazo fue evidente la mejor sobre vida comparado con el tratamiento médico. Posteriomente la angioplastía con balón se presenta como opción con el inconveniente de la restenosis por el tejido elástico abundante con recoil del vaso. El stent representó un gran adelanto, primero con las lesiones protegidas y luego en las situaciones de urgencia como en el infarto agudo de miocardio, así como también en las urgencias que surgen durante los procedimientos electivos. Presentamos dos casos representativos de nuestra serie, en los que se pudo solucionar el problema por medio de la angioplastía percutánea con implante de stent en el tronco de la coronaria izquierda. El primero en un cuadro de urgencia de oclusión total del tronco de la coronaria izquierda durante un infarto agudo de miocardio y en el segundo la lesión ideal en el tercio medio del tronco de la coronaria izquierda pos-irradiación de mediastino, con buena función ventricular. La sobrevida de los pacientes con stent en el tronco de la coronaria izquierda es altamente competitiva con respecto a la cirugía de By-Pass convencional, pero necesita el apoyo científico de un estudio randomizado comparando angioplastías con stent versus cirugía de By Pass

RESUMO

A cuarenta y dos pacientes con lesión no protegida de tronco de coronaria izquierda se les realizó angioplastia coronaria con implante de 45 stents. El 95 por ciento de los pacientes tenía, al momento del tratamiento, angina inestable y/o infarto de miocardio. Los resultados intrahospitalarios mostraron éxito técnico-clínico en el 100 por ciento de los casos. En la evolución alejada (13,6 meses) la sobrevida fue del 88 por ciento y la necesidad de nuevos procedimientos de revascularización del 19 por ciento. La mortalidad alejada no estuvo asociada a reestenosis silente del stent y/o oclusión subaguda del mismo
