We report a case of systemic light chain amyloidosis with cardiac involvement, preceded by a monoclonal IgG lambda gammopathy. The clinical diagnosis was based on signs of heart failure, elevated biomarkers, and imaging findings. The diagnosis was confirmed by elevated light chains in the blood and urine, and the presence of amyloid deposits in the periumbilical fat biopsy and in different segments of the digestive tract. Treatment with daratumumab plus bortezomib plus dexamethasone was initiated, and autologous hematopoietic stem cell therapy was administered 22 months after diagnosis, with a favorable clinical outcome.

Objective. To know the clinical characteristics and determine the related factors to higher in-hospital mortality in patients with cardiogenic shock (CS) due to myocardial infarction in a Peruvian reference hospital. Materials and methods. We conducted a prospective single-center cohort study, to evaluate the clinical characteristics, treatment, and complications of patients with CS due to myocardial infarction from March 2019 to August 2020 at the Instituto Nacional Cardiovascular INCOR. Factors related to higher in-hospital mortality and during follow-up were evaluated. Also, the IABP shock II score was applied to stratify the cohort. Results. Forty patients were included in the study, 75% of cases were due to left ventricular dysfunction, most of the men and with a median age of 75 (69-82) years. Fifty percent of cases presented CS after admission to the emergency room. Patients strat...

Objective. To describe the quality of life in patients with idiopathic ventricular arrhythmias treated at the Instituto Nacional Cardiovascular INCOR in Lima -Peru. Materials and methods. Analytical and cross-sectional study of patients with idiopathic ventricular arrhythmias treated by 3D ablation or antiarrhythmic therapy between July 2017 and December 2019 to whom the SF-36 health questionnaire was applied to assess quality of life related to health. Results. Fifty-two patients with idiopathic ventricular arrhythmias were included (34 underwent 3D ablation, and 18 underwent antiarrhythmic therapy only). The percentage of recurrence (14.7% vs. 50%, p=0.01) and adverse effects (0% vs. 22.2%, p=0.011) were lower in the 3D ablation group compared to the antiarrhythmic group. The mean standardized scores obtained from the Spanish version of the Health Survey SF-36v2, applied to the 3D abla...

Objetivo. Describir la calidad de vida en pacientes con arritmias ventriculares idiopáticas, tratados en el Instituto Nacional Cardiovascular INCOR de Lima-Perú. Materiales y métodos. Estudio analítico y transversal de pacientes con arritmias ventriculares idiopáticas, tratados mediante ablación 3D o terapia antiarrítmica entre julio 2017 y diciembre de 2019 a quienes se aplicó el cuestionario de salud SF-36 para evaluar la calidad de vida relacionada con la salud. Resultados. Se incluyeron a 52 pacientes con arritmias ventriculares idiopáticas (34 fueron a ablación 3D y 18 solo terapia antiarrítmica). El porcentaje de recurrencia (14,7% vs. 50%, p=0,01) y efectos adversos (0% vs. 22,2%, p=0,011) fueron menores en el grupo ablación 3D comparado con el grupo antiarrítmico. Los puntajes estandarizados promedios obtenidos de la versión española del cuestionario de salud SF-36...

Objetivos: Se desea saber la incidencia, los factores asociados y la mortalidad a 30 días de los pacientes con insuficiencia cardiaca (IC) postinfarto de miocardio con elevación del segmento ST (IMCEST) en Perú. Métodos: Estudio observacional, de cohortes, multicéntrico a nivel nacional, de pacientes enrolados en el registro peruano de IMCEST, excluyendo los pacientes con antecedente de IC. Se compararon las características epidemiológicas, tratamiento y evolución a 30 días de los pacientes con (grupo 1) y sin (grupo 2) IC postinfarto. Resultados: De 388 pacientes se encontró un 48.7% con síntomas de IC o fracción de eyección de ventrículo izquierdo < 40% postinfarto (grupo 1). La edad > 75 a˜nos, el infarto de pared anterior y la ausencia de signos electrocardiográficos de reperfusión fueron los factores relacionados a mayor incidencia de IC. La mortalidad intrahospital...

Objectives: The aim of this study is to determine the incidence, associated factors, and 30-day mortality of patients with heart failure (HF) after ST elevation myocardial infarction (STEMI) in Peru. Methods: Observational, cohort, multicentre study was conducted at the national level on patients enrolled in the Peruvian registry of STEMI, excluding patients with a history of HF. A comparison was made with the epidemiological characteristics, treatment, and 30 day-outcome of patients with (Group 1) and without (Group 2) heart failure after infarction. Results: Of the 388 patients studied, 48.7% had symptoms of HF, or a left ventricular ejection fraction <40% afterinfarction (Group 1). Age > 75 years, anterior wall infarction, and the absence of electrocardiographic signs of reperfusion were the factors related to a higher incidence of HF. The hospital mortality in Group 1 was 20.6%, and ...

Objective. To describe the initial experience in ablation of cardiac arrhythmias using 3D mapping at the Instituto Nacional Cardiovascular INCOR (Lima, Peru). Methods. A retrospective descriptive study was carried out. During February 2020, data was collected from the medical records of all patients in whom ablation was performed using 3D mapping from July 2017 to December 2019. This procedure was performed in patients with symptomatic arrhythmia refractory to antiarrhythmic therapy. Results. Data were collected from 123 patients (median age: 46 years, 64.2% male), who had a median time of illness of 6 years. Among the arrhythmias treated, 19% had atrial fibrillation, 17.5% atrial tachycardia, 17.5% idiopathic ventricular arrhythmias, 16.6% Wolf Parkinson White syndrome / Atrioventricular reentrant tachycardia, 11.1% ventricular arrhythmias of the His-Purkinje conduction system, 9.5% sca...
