Objective: To identify the relationship between red blood cell distribution width (RDW, %), interleukin-6 (IL-6) (pg/ml), high sensitivity-c-reactive protein (hs-CRP) (mg/l), in-hospital mortality and disease severity among patients with heart failure (HF). Methods: Prospective cohort. We included adults diagnosed with acute non-ischemic HF in 2015. The dependent variables were in-hospital mortality (yes or no) and disease severity. The latter was assessed with the Get With The Guidelines-HF score. We used hierarchical regression models to describe the pattern of association between biomarkers, mortality, and severity. We used the Youden index to identify the best cut-off for mortality prediction. Results: We included 167 patients; the mean age was 72.61 (SD: 11.06). The majority of patients presented with New York Heart Association classification II (40.12%) or III (43.11%). After adjusting for age and gender, all biomarkers were associated with mortality. After adding comorbidities, only IL-6 was associated. The final model with all clinical variables showed no effect from any biomarker. The best cut-off for RDW, hs-CRP and IL-6 for mortality were 14.8, 68.7 and 52.9, respectively. IL-6 presented the highest sensitivity (100%), specificity (75.35%) and area under the curve (0.91). Conclusions: No biomarker is independent from the most important clinical variables; therefore it should not be used for management modifications. Resumo: Objetivo: Identificar a relação entre a amplitude de distribuição dos eritrócitos (ADE, %), IL-6 (pg/nl), hs-PCR (mg/l), mortalidade intra-hospitalar e gravidade da doença em doentes com insuficiência cardíaca (IC). Métodos: Coorte prospetiva. Incluímos adultos com IC aguda de etiologia não isquémica durante o ano de 2015. As variáveis dependentes foram a mortalidade intra-hospitalar (sim ou não) e a gravidade da doença. A última foi avaliada com o score de Get With Guidelines-HF (GWTG-HF). Utilizámos modelos de regressão hierarquizados para descrever o padrão de associação entre os biomarcadores, mortalidade e gravidade. Utilizámos o índice Youden para identificar o melhor cut-off na previsão da mortalidade. Resultados: Foram incluidos 167 doentes. A idade média foi de 72,61 (MS: 11,6). A maioria dos doentes estava em Classe II (40,12%) ou III NYHA (43,11%). Após ajuste para idade e género, todos os biomarcadores se associaram à mortalidade. Após adicionar as comorbilidades, só a IL-6 se associou com mortalidade. O modelo final com todas as variáveis clínicas incluidas não mostrou qualquer efeito de qualquer dos biomarcadores estudados. Os melhor cut-off de ADE, hs-PCR e IL-6 para mortalidade foi de 14,8, 68,7 e 52,9 respetivamente. A IL-6 apresentou a sensibilidade mais elevada (100%), especificidade (75,35%) e área sob a curva (0,91). Conclusões: Nenhum dos biomarcadores analisados se revelou independente das variáveis clínicas mais importantes, pelo que os biomarcadores estudados não devem ser utilizados como orientação clínica.

To analyze the Peruvian scientific production on Heart Failure (HF) in the period 2000-2020.We performed an observational bibliometric study, in the Scopus and Scielo database, of documents published on heart failure by an author with Peruvian affiliation, between the years 2000 and 2020. We describe variables of scientific production, number of annual publications, documents, characteristics of the publications, and institutions. The collaborative networks were analyzed by building a network of nodes using the VOSViewer v1.6.5 software.A 236 publications were found in Scopus and 55 in Scielo. The largest number of documents were original articles followed by review articles. The journal "The Lancet" and "Revista Peruana de Medicina Experimental y Salud Pública" were those that had the highest number of publications. Thirty-one countries were registered that had at least 5 documents published with an author from Peru. Scientific collaboration was mainly with the United States and at the regional level with Argentina. 55 documents were published with only Peruvian authors.The scientific production in HF by Peruvian authors is in exponential growth. And the Universidad Peruana Cayetano Heredia/CRÓNICAS is the Peruvian institution with the most publications on it.Analizar la producción científica peruana sobre insuficiencia cardiaca (IC) en el periodo 2000-2020.Se realizó un estudio observacional bibliométrico en la base de datos de Scopus y Scielo de documentos publicados sobre IC por algún autor con filiación peruana entre los años 2000 y 2020.

La miocardiopatía inducida por arritmia (MCIA) es una alteración potencialmente reversible, en la cual la disfunción ventricular es inducida o mediada por arritmias auriculares o ventriculares. El reconocimiento temprano de la MCIA y el tratamiento temprano de la arritmia causal, mediante fármacos o técnicas de ablación, tienen como resultado la resolución de los síntomas y la recuperación de la función ventricular...

Background Coronary disease (CD) is the main cause of mortality worldwide. Data about trends and geographical variation in CD mortality is available in some American countries. This information varies among countries since CD risk factors frequencies vary. Objective To describe the trend and geographical variation of coronary disease (CD) mortality in Peru, 2005–2017. Methods Analysis of secondary data of the Peruvian Ministry of Health’s registry of deaths. We analyzed CD mortality. We described the absolute and relative frequency of deaths and age-standardized mortality rate (ASMR) by natural regions, departments, age, sex, and year. We also described the change of ASMR between two periods (2005–2010 vs. 2011–2017). Results There were 64,721 CD deaths between 2005 and 2017 (4.12% among all deaths). The absolute frequency of CD deaths was 5,665 and 6,565 in 2005 and 2017, respectively. CD mortality was more frequent in men and older adults. The ASMR varied among natural regions, being higher in the Coast (19.61 per 100,000 inhabitants). The change between the two periods revealed that almost all departments reduced their ASMRs, except for Callao, Lambayeque, and Madre de Dios. Conclusion CD mortality has increased in Peru. Mortality was higher in men and older adults, and it varied among departments. More political efforts are needed to reduce these trends.

Fabry disease (FD), like COVID-19, can affect multiple organs, including the lungs. Patients with FD would be expected to develop severe forms of COVID-19, not only because of lung involvement but also because of renal involvement and other comorbidities. We present two cases of patients with Fabry disease who had an infection by COVID-19. In the two cases presented, they presented mild forms of COVID-19. Although the role of the X chromosome mutation in FD on the development of severe forms of COVID-19 is unknown; in the cases presented, it is suggested that it may play a protective role in the development of COVID-19. Two cases are presented; it is suggested that FD would not be a risk factor for severe COVID-19.

Objectives The purpose of this article was to determine the change in the volume of pacemaker implantations with the COVID‐2019 pandemic and to assess the change in the number of pacemaker implants according to etiology during the pandemic. Background The establishment of a mandatory social isolation have generated a decrease in activities in cardiology units. Methods Descriptive, cross‐sectional study that used a database of a Peruvian Hospital. Time was divided into three categories: Before COVID period and COVID period including Previous to Social isolation (SI) and Social Isolation. The number of pacemaker implantations were compared per the same amount of time. Results A reduction in the pacemaker implant of 73% (95% CI: 33‐113; P, This article reports the reduction of de‐novo pacemaker implants in a Peruvian hospital due to the COVID‐19 pandemic. The reduction in the number of de‐novo pacemaker occurred independently of the etiology.

The disease of ischemic heart disease according to the World Health Organization is one of the leading causes of death in the world. According to previous research, the lobular cleft of the ear indicates the presence of ischemic heart disease. In this sense, an analysis is sought through image processing of the lobular slit in order to directly relate the main characteristics as well as the size and depth of this with the degree of advancement of the ischemic heart disease. This project develops the segmentation stage of the lobular cleft to be able to identify the area of interest. This purpose was achieved using image processing obtained from a Smartphone, and based on the mathematical software tool MATLAB, the results obtained show us the segmentation of each ear obtaining effectiveness of the 75% allowing the identification of the zone of interest (cleft), to be able to analyze it in a future process.
