Abstract

RESUMEN La amiloidosis es un desorden sistémico producido por el depósito de fibrillas de proteínas insolubles que se pliegan y depositan en el miocardio. Los pacientes con amiloidosis y compromiso cardíaco tienen mayor mortalidad respecto a pacientes sin compromiso cardíaco. Las dos formas de amiloidosis más prevalentes que se asocian con compromiso cardíaco son la amiloidosis AL, por el depósito de las cadenas livianas de las inmunoglobulinas, y la amiloidosis ATTR, por el depósito de la proteína transtiretina (TTR) en forma mutada o senil. Este artículo tiene el objetivo de revisar las diferentes modalidades de imágenes cardíacas (ecocardiografía, resonancia magnética cardiaca, medicina nuclear y tomografía) que permiten determinar la severidad del compromiso cardíaco en pacientes con amiloidosis, el tipo de amiloidosis y su pronóstico. Finalmente, se sugiere un algoritmo diagnóstico para determinar el compromiso cardíaco en la amiloidosis adaptado a las herramientas diagnósticas disponibles localmente, con un enfoque práctico y clínico. ABSTRACT Cardiac amyloidosis is a systemic disorder caused by the extracellular deposition of fibrils of insoluble proteins that misfold and deposit in the myocardium. Patients with amyloidosis and cardiac involvement have higher mortality rate than those without cardiac involvement. The two most prevalent types are amyloidosis with cardiac involvement are light-chain amyloidosis (AL) due to immunoglobulin light chain deposition and transthyretin amyloidosis (ATTR) due to deposition of mutated or senile forms of the transthyretin (TTR) protein. The aim of this paper is to review the different modalities of cardiac imaging tests (echocardiography, cardiac magnetic resonance imaging, nuclear medicine images and computed tomography scan) that can determine the severity of cardiac involvement in patients with amyloidosis, the type of amyloidosis and its prognosis. Finally, a diagnostic algorithm is proposed to determine cardiac involvement in amyloidosis, tailored to the diagnostic tools locally available with a practical and clinical approach.

Abstract

Background: The aim of the study was to compare if there were any differences between discontinuation of vitamin K antagonists and direct oral anticoagulants and evaluate the factors associated with such discontinuation in newly diagnosed nonvalvular atrial fibrillation. Methods: We conducted a prospective cohort study. Patients were followed-up for 12 months. Since the assignment of anticoagulation treatment was not randomized, propensity score weighting was used considering the baseline characteristics potentially associated with the exposure and result. Factors associated with the discontinuation of anticoagulant treatment were analyzed with a weighted Cox proportional hazards model. A total of 379 patients were included; mean age was 78 years (SD ± 9) and 58% were women. Median follow-up was 362 days (interquartile range: 347-370 days) and 1% was lost to follow-up. Results: The model of time to discontinuation based on inverse probability treatment weighting showed a crude HR of 1.40 (95% CI, 0.79-2.48, and of 1.26 (95% CI, 0.75-2,12, after adjustment for age, type of atrial fibrillation, radiofrequency catheter ablation, bleeding, number of chronic medications and number of medical visits during follow-up for the group treated with direct oral anticoagulants compared with the vitamin K antagonists. Conclusions: In our setting, anticoagulant discontinuation in nonvalvular atrial fibrillation would not be associated with the type of drug used, age or type of atrial fibrillation. Radiofrequency catheter ablation, bleeding events and the number of medical visits were associated with treatment discontinuation., Introducción: El objetivo del estudio fue comparar si existe diferencia en la discontinuación de los antagonistas de la vitamina K y los anticoagulantes directos y evaluar sus factores asociados en la fibrilación auricular de reciente diagnóstico. Material y métodos: Se realizó un estudio de cohortes prospectivo. El período de seguimiento fue de 12 meses. Debido a que la asignación del tratamiento no fue al azar, se realizó una ponderación por puntaje de propensión considerando las características basales potencialmente asociadas a la exposición y al resultado. Se evaluaron factores asociados a la discontinuación del anticoagulante mediante un modelo de Cox ponderado. Se incluyeron 379 pacientes con una edad media de 78 años (DE ± 9) y una prevalencia de sexo femenino del 58%. La mediana de seguimiento fue de 362 días (rango intercuartilo: 347-370 días). La pérdida de seguimiento fue del 1%. Resultados: El modelo de tiempo a la discontinuación del tratamiento anticoagulante ponderado evidenció un HR crudo de 1,40 (IC 95%: 0,79-2,48) y uno ajustado por edad, tipo de fibrilación auricular, ablación por radiofrecuencia, sangrado, cantidad de fármacos crónicos y de consultas médicas durante el seguimiento de 1,26 (IC 95%: 0,75-2,12) para el grupo tratado con anticoagulantes directos en comparación con el tratado con antagonistas de la vitamina K. Conclusiones: En nuestro medio, la discontinuación de los anticoagulantes en la fibrilación auricular no se asociaría con el tipo de fármaco empleado, la edad o el tipo de arritmia. La ablación por radiofrecuencia, la ocurrencia de sangrado y el número de consultas médicas se asociaron con la discontinuación.

Abstract

Cardiac amyloidosis is a systemic disorder caused by the extracellular deposition of fibrils of insoluble proteins that misfold and deposit in the myocardium. Patients with amyloidosis and cardiac involvement have higher mortality rate than those without cardiac involvement. The two most prevalent types are amyloidosis with cardiac involvement are light-chain amyloidosis (AL) due to immunoglobulin light chain deposition and transthyretin amyloidosis (ATTR) due to deposition of mutated or senile forms of the transthyretin (TTR) protein. The aim of this paper is to review the different modalities of cardiac imaging tests (echocardiography, cardiac magnetic resonance imaging, nuclear medicine images and computed tomography scan) that can determine the severity of cardiac involvement in patients with amyloidosis, the type of amyloidosis and its prognosis. Finally, a diagnostic algorithm is proposed to determine cardiac involvement in amyloidosis, tailored to the diagnostic tools locally available with a practical and clinical approach., La amiloidosis es un desorden sistémico producido por el depósito de fibrillas de proteínas insolubles que se pliegan y depositan en el miocardio. Los pacientes con amiloidosis y compromiso cardíaco tienen mayor mortalidad respecto a pacientes sin compromiso cardíaco. Las dos formas de amiloidosis más prevalentes que se asocian con compromiso cardíaco son la amiloidosis AL, por el depósito de las cadenas livianas de las inmunoglobulinas, y la amiloidosis ATTR, por el depósito de la proteína transtiretina (TTR) en forma mutada o senil. Este artículo tiene el objetivo de revisar las diferentes modalidades de imágenes cardíacas (ecocardiografía, resonancia magnética cardiaca, medicina nuclear y tomografía) que permiten determinar la severidad del compromiso cardíaco en pacientes con amiloidosis, el tipo de amiloidosis y su pronóstico. Finalmente, se sugiere un algoritmo diagnóstico para determinar el compromiso cardíaco en la amiloidosis adaptado a las herramientas diagnósticas disponibles localmente, con un enfoque práctico y clínico.

Abstract

La arritmia ventricular frecuente (AVF) puede ser una alteración eléctrica primaria, o estar asociada a una cardiopatía. El impacto pronóstico y terapéutico depende de la presencia de cardiopatía estructural. . El ecocardiograma doppler transtorácico ha sido el estudio complementario más importante para evaluar la presencia de alteraciones estructurales cardíacas. El objetivo de nuestro estudio consiste en determinar la capacidad de la resonancia magnética cardíaca (RMC) para detectar alteraciones estructurales a nivel cardíaco en pacientes con ecocardiograma doppler normal y conocer la incidencia de eventos cardiovasculares adversos en el seguimiento. Se incluyeron 66 pacientes consecutivos con arritmia ventricular frecuente definido como extrasístoles ventriculares > 5000 en un registro de Holter de 24 hs, taquicardia ventricular o muerte súbita resucitada con ecocardiograma doppler normal. A todos los pacientes se les realizó una resonancia magnética cardíaca con protocolo para evaluar miocardiopatías. El 57% de los pacientes presentó alguna alteración estructural, siendo las patologías diagnosticadas más prevalente: la secuela de miocarditis, el miocardio no compactado y la secuela de infarto subendocárdico. En el seguimiento medio de 24 ± 22 meses, la incidencia de eventos cardiovasculares adversos fue 6.06%. El número de extrasístoles ventriculares fue mayor en aquellos pacientes con resonancia anormal. Este trabajo demuestra que en pacientes con arritmia ventricular frecuente con ecocardiograma doppler normal, la realización de una resonancia magnética cardíaca con gadolinio permite detectar en más de la mitad de los casos alguna alteración estructural., IntroductionFrequent ventricular arrhythmia can be a primary electrical disturbance or may beassociated to cardiomyopathy. The prognostic and therapeutic impact depends onthe presence of structural heart disease. Transthoracic Doppler echocardiographyhas been the most important complementary study to evaluate the presence of cardiacstructural abnormalities.ObjectivesThe aims of this study were to determine the ability of cardiac magnetic resonanceimaging to detect structural heart disease in patients with normal Doppler echocardiogramand to assess the incidence of adverse cardiovascular events during followup.MethodsThe study included 66 consecutive patients with frequent ventricular arrhythmiadefined as > 5000 ventricular extrasystoles in 24-hour Holter monitoring, ventriculartachycardia or resuscitated cardiac respiratory arrest with normal Dopplerechocardiogram. All patients underwent cardiac magnetic resonance imaging to assesscardiomyopathies.ResultsFifty-seven percent of patients had structural heart disease. The most prevalentdiagnosed pathologies were myocarditis sequelae, non-compacted myocardium andsubendocardial infarction scar. At mean follow-up of 24 ± 22 months, the incidenceof adverse cardiovascular events was 6.06 %. The number of ventricular extrasystoleswas higher in patients with abnormal cardiac magnetic resonance.DiscussionThis work demonstrates that in patients with frequent ventricular arrhythmia andnormal Doppler echocardiogram, gadolinium cardiac magnetic resonance imagingcan detect structural heart disease in more than half of the cases. Patients with frequentventricular arrhythmia during Holter monitoring, normal Doppler echocardiogramand mild alterations in the magnetic resonance present low risk of cardiovascularevents.

Abstract

Objectives: Patients diagnosed with transthyretin amyloid cardiomyopathy (ATTR-CM) often experience poor outcomes due to the development of heart failure (HF). Tricuspid regurgitation (TR) has been found to be correlated with adverse outcomes in patients with HF. This study aims to assess whether the presence of significant TR is associated to adverse cardiac outcomes in patients diagnosed with ATTR-CM., Materials and Methods: Retrospective study of ATTR-CM patients enrolled in the Institutional Registry of Amyloidosis (NCT01347047). Patients were categorized based on the presence of significant TR (moderate or severe according to current guidelines criteria) or absence of significant TR. All patients were followed up for 2 years to assess the incidence of the composite outcome of death or HF hospitalization., Results: A total of 93 ATTR-CM patients were included. The mean age at diagnosis was 82.5 [IQR 75 - 86] years, 86% were male, and the mean left ventricular ejection fraction was 52% [IQR 43 - 60]. Among them, 32.3% (n = 30) patients had significant TR. Patients with significant TR had higher NTpro-BNP values (5308 vs 2454, pg/mL, p = 0.004), and a lower left ventricular ejection fraction (44 vs. 56%, p = 0.0002) compared to patients without significant TR. The incidence of the primary outcome was higher in patients with significant TR (77% vs. 30%, p<0.001). In a multivariate Cox regression analysis, only NTpro-BNP, as a numerical variable (HR 1.00, 95% CI 1.00005-1.0002, p = 0.001), and significant TR (HR 2.23, 95% CI 1.12-4.42, p=0.021) were independently associated with the composite outcome of death or HF hospitalization., Conclusions: In patients diagnosed with ATTR-CM, the presence of significant TR was associated with worse outcomes., Competing Interests: Conflict of interest: The authors declare no conflict of interest

Abstract

Introduction: Transthyretin cardiac amyloidosis (ATTR-CM) usually presents as heart failure with preserved ejection fraction. Its diagnosis has a significant clinical impact, as specific treatment is currently available. The aim of this study is to assess the prevalence of ATTR-CM in patients hospitalized for heart failure with preserved ejection fraction and septal thickness in our region., Methods: Cross-sectional study. Patients over 18 years old hospitalized for heart failure with preserved ejection fraction (greater than 50%) and septal thickness greater than or equal to 12 mm during the period from 8/2019 to 1/2023 were prospectively included. A pyrophosphate bone scintigraphy (PYP) was planned to assess cardiac involvement. The prevalence of ATTR-CM and its 95% confidence interval were calculated., Results: A PYP was performed in 59/82 patients. The median age was 85 [IQR 78-88] years old, 54% women. On admission, 61% had atrial fibrillation/flutter rhythm and the median NT-Pro-Bnp was 3536 [IQR 1700-7748] pg/nl. The mean ejection fraction was 57% (± 5). The prevalence of ATTR-CM diagnosed by bone scintigraphy with PYP was 19% (95%CI 9.7-30.1). No differences were found compared with those patients who did not perform a PYP., Conclusion: In patients admitted for heart failure with preserved ejection fraction and septal thickness, the diagnosis of ATTR-CM was relatively common (1/5). We believe that it should be routinely explored.

Abstract

Light chain amyloidosis (AL) is a rare and underdiagnosed disease. The best treatment available is autologous bone marrow transplantation (BMT). Cardiac involvement is the main prognostic determinant in this pathology and sometimes an impediment to receive BMT. We present a clinical case of a 44-year-old who consulted for signs and symptoms of heart failure (HF) with elevated cardiac biomarkers. A transthoracic echocardiogram showed increased wall thickness with global hypokinesia and mildly impaired ejection fraction (50%). The patient was admitted to the coronary unit for treatment with diuretics and for etiological study of the condition. In view of the suspicion of infiltrative disease, a bone scintigraphy with pyrophosphate and free light chains in serum were requested. The bone scintigraphy was not suggestive of transthyretin amyloidosis and the free light chains showed a ratio of less than 0.26 with lambda predominance. A gum biopsy was performed and confirmed the diagnosis of AL amyloidosis. After diagnosis, specific chemotherapy treatment with Cyclophosphamide, Bortezomib and Dexamethasone (CYBORD scheme) and Daratumumab was started. He evolved with refractory HF so it was decided to admit him to the cardiac transplantation list, receiving the same soon after, with good evolution. This allowed the patient to restart the chemotherapy regimen and finally receive BMT, with good evolution.

Abstract

Objective: To describe the evolution of serum free light chains (FLC) in the period between orthotopic heart transplantation (OHT) and autologous stem cell transplantation (ASCT), the hematological response one year after ASCT and chemotherapy and immunosuppressive treatment in patients with AL amyloidosis., Method: Case series of consecutive patients diagnosed with AL amyloidosis who received OHT followed by ASCT from the Institutional Registry of Amyloidosis of the Italian Hospital of Buenos Aires, between January 2010 and November 2021. FLC values between transplants and at year post ASCT. Quantitative variables were described with their median and interquartile range. Categorical variables as absolute and relative frequencies., Results: Of 106 patients with AL amyloidosis, 6 had an OHT followed by ASCT. The median age was 55 years. Most were men (n = 5). In the period between transplants, the involved CLL decreased in two patients and remained stable in three. All achieved complete hematologic remission 1 year after ASCT. A single patient presented relapse in the transplanted solid organ. Tacrolimus, mycophenolate mofetil, and corticosteroids were the immunosuppressive regimen used after OHT., Conclusions: OHT represents a treatment option in patients with severe heart failure due to amyloidosis, allowing later intensive treatment with induction chemotherapy and ASCT. Although studies are lacking, immunosuppressive therapy after OHT might have some effect on clonal plasma cells., (Copyright: © 2023 Permanyer.)

Abstract

The COVID-19 pandemic elicited important changes in community habits and behaviors, including a distancing of people from the healthcare system. The objective of this work was to understand the causes that gave rise to changes in behavior from an individual perspective in the Argentine Republic. We performed a cross-sectional, web-based survey using an online questionnaire. The survey was distributed via the WhatsApp application for smartphones among subjects across the Argentine territory using a combination of convenience and snowball sampling. We received 6176 responses. Almost 70% of respondents manifested fear of visiting a physician. One third of respondents manifested having a desire or need in at least one occasion of visiting a physician but, of these, 48% avoided it. The main reasons for avoiding visits were: 1) a recommendation of staying home (40%); 2) lack of access to the physician (35%); and 3) fear of contagion (26%). The most common form of consultation was through unconventional means (e-mail, telephone, or WhatsApp). One of 5 respondents had difficulties to obtain a medication prescription and 5% stopped the use of at least one medication. Regarding healthy habits, almost 2/3 of those surveyed stated that they became more sedentary; 11% of hypertensive patients increased their consumption of salt and 15% saw their blood pressure values increase, while 16% of dyslipidemic patients showed increased consumption of fats.
