Routine histopathological evaluation of the explanted heart is essential to confirm the etiology of heart failure, especially in cases clinically diagnosed as dilated cardiomyopathy. In addition, routine follow-up through endomyocardial biopsies shows that acute cellular rejection is still a frequent complication after a heart transplant, especially within the first year, and that antibody-mediated rejection has a low incidence in our population.
Background: Infection caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) exhibits a strong infectivity but less virulence compared to severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS). In terms of cardiovascular morbidity, susceptible population include elderly and patients with certain cardiovascular conditions. This infection has been associated with cardiac injury, cardiovascular complications and higher mortality. Objectives: The main objective of the CARDIO COVID 19-20 Registry is to determine the presence of cardiovascular comorbidities and cardiovascular complications in COVID-19 infected patients that required in-hospital treatment in different Latin American institutions. Methods: The CARDIO COVID 19-20 Registry is an observational, multicenter, ambispective, and hospital-based registry of patients with confirmed COVID-19 infection who required inhospital treatment in Latin America. Enrollment of patients started on May 01, 2020 and was initially planned to last three months; based on the progression of pandemic in Latin America, enrollment was extended until December 2020, and could be extended once again based on the pandemic course in our continent at that moment. Conclusions: The CARDIO COVID 19-20 Registry will characterize the in-hospital population diagnosed with COVID-19 in Latin America in order to identify risk factors for worsening of cardiovascular comorbidities or for the appearance of cardiovascular complications during hospitalization and during the 30-day follow up period.
Objetivos: Determinar las características clínicas, de imágenes y laboratoriales así como la sobrevida al año del diagnóstico de pacientes con amiloidosis cardíaca en un hospital de referencia nacional. Materiales y métodos: Estudio de serie de casos. Evaluamos las características clínicas, exámenes complementarios y supervivencia de pacientes con amiloidosis cardíaca diagnosticados, tratados y seguidos en el servicio de Cardiología Clínica del Instituto Nacional Cardiovascular - INCOR EsSalud. Resultados: Se encontraron 8 pacientes con diagnóstico de amiloidosis cardíaca. La mediana de la edad fue 64.5 años y el 75% de sexo masculino. La etiología fue amiloidosis cardíaca no especificada (25%), amiloidosis cardíaca transtiretina (37.5%) y amiloidosis cardíaca de cadenas ligeras (37.5%). La insuficiencia cardíaca sintomática (NYHA II-III) fue la presentación inicial más común (87.5%). Las manifestaciones extracardíacas más frecuentes fueron: neuropatía sensitivo-motora (62.5%), muscu- loesqueléticas (37.5%), nefropatía (25%), síndrome de túnel carpiano bilateral (25%), gammapatías monoclonales (25%) y efusión pleural refractaria (25%). La sobrevida al año fue del 75% y la causa de muerte en los 2 fallecidos fue muerte súbita. Conclusiones: En este estudio sobre amiloidosis cardíaca en un centro especializado las manifestaciones clínicas más frecuentes fueron la insuficiencia cardíaca y la neuropatía sensitivo-motora. La mortalidad fue del 25% al año, y en todos los casos como muerte súbita.
Background: COVID-19 is a global disease caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Patients with a severe or critical illness can develop respiratory and cardiovascular complications. This study aimed to describe a Latin American and Caribbean (LA&C) population with COVID-19 to provide information related to this disease, in-hospital cardiovascular complications and in-hospital mortality. Methods: The CARDIO COVID-19-20 Registry is an observational, multicenter, ambispective, and hospital-based registry of patients with confirmed COVID-19 infection that required in-hospital treatment in LAC. Enrollment of patients started on May 01, 2020, and ended on June 30, 2021. Results: The CARDIO COVID-19-20 Registry included 3260 patients from 44 institutions of 14 LA&C countries. 63.2% patients were male and median age was 61.0 years old. Most common comorbidities were overweight/obesity (49.7%), hypertension (49.0%), and diabetes mellitus (26.7%). Most frequent cardiovascular complications were cardiac arrhythmia (9.1%), decompensated heart failure (8.5%), and pulmonary embolism (3.9%). 53.5% of patients were admitted to Intensive Care Unit (ICU), and median length of stay at the ICU was 10.0 days. Support required in ICU included invasive mechanical ventilation (34.2%), vasopressors (27.6%), inotropics (10.3%) and vasodilators (3.7%). Rehospitalization after 30-day post discharge was 7.3%. In-hospital mortality and 30-day post discharge was 25.5% and 2.6%, respectively. Conclusions: The LA&C population with COVID-19 patients and hospitalization, has a considerable burden of cardiovascular diseases related to a worse prognosis. It is necessary to carry out a more specific analysis to determine risk factors for cardiovascular outcome.
La Diabetes Mellitus (DM) es una enfermedad crónica cardiometabólica no transmisible, que origina complicaciones macrovasculares como aterosclerosis, enfermedad coronaria e insuficiencia cardíaca (IC). Existe una relación bidireccional entre IC y DM, siendo IC el segundo evento cardiovascular inicial más frecuente en pacientes con diabetes. Incluso puede ser la primera complicación cardiovascular, antes que el infarto de miocardio.La DM puede conducir a IC a través de mecanismos mediados por aterosclerosis e independientemente de esta. En el primer caso, se produce depósito de colesterol en las arterias coronarias, favorecido por la presencia de otros factores de riesgo. En el segundo caso, a través de mecanismos no aterogénicos (denominada Cardiomiopatía Diabética), conduciendo a cambios estructurales y funcionaes.El tratamiento de la IC con fracción de eyección reducida en el paciente diabético no difiere del de la población no diabética. Se debe conseguir el triple bloqueo neurohumoral. En el caso de los pacientes con IC con fracción de eyección preservada hasta la fecha no tenemos terapia específica que disminuya la morbimortalidad cardiovascular.En el tratamiento de la diabetes del paciente con IC sobresalen claramente los inhibidores del cotransportador sodio-glucosa tipo 2 (iSGLT2) que además de su efecto glucosúrico y natriurético, presentan efectos pleiotrópicos que ejercen una acción metabólica, hemodinámica y en la viabilidad celular al prevenir apoptosis y muerte celular. Finalmente, los beneficios clínicos de los inhibidores SGLT2 en IC van más allá del control glicémico, como lo demostró el estudio DAPA-HF; iniciando una nueva era en el tratamiento del paciente con IC con fracción de eyección reducida.
