Acciones impostergables sobre las enfermedades cardiovasculares en Cuba / Imperative Actions on Cardiovascular Diseases in Cuba

Las enfermedades cardiovasculares afectan el corazón y los vasos sanguíneos producto de la interacción combinada de factores de riesgos metabólicos, conductuales, socioeconómicos y ambientales como son: la presión arterial elevada, dieta no saludable, colesterol alto, diabetes, obesidad, hábito de fumar, enfermedad renal, estrés, consumo de alcohol y la poca actividad física entre otros. El número de muertes por enfermedades cardiovasculares en 2019 representó el 33 por ciento de las muertes globales, por la cardiopatía isquémica con 9,1 millones y el accidente vascular cerebral con 6,6 millones representaron el 85 por ciento de las muertes cardiovasculares mundialmente. A pesar de que las tasas estandarizadas de mortalidad ajustadas por edad se han reducido entre los años 2000-2019, el número total de fallecidos se ha incrementado en un 25 por ciento debido a el envejecimiento poblacional, el incremento de la población y la mayor incidencia de eventos fatales en pacientes con diabetes mellitus.1,2 Este envejecimiento poblacional es de particular importancia, la Organización Mundial de la Salud (OMS) estima que para el 2030 el número de personas mayores de 60 años estará en un 34 por ciento mayor con 1,4 mil millones y para el 2050 se duplicaría a 2,2 mil millones.3 El Atlas de Obesidad Mundial del 2023 estima que para el 2035 los niveles de sobrepeso y obesidad alcanzarán los 4 mil millones de personas comparados con los 2,6 mil millones en el 2020. El Diabetes Collaborators 2021estima que el número de pacientes que viven con diabetes puede llegar a 1,3 mil millones de personas comparado con los 529 millones existentes en el 2021.4,5 Estos datos demuestran la necesidad de incrementar...(AU)

Racionamiento, inflación e inequidad sanitaria en Venezuela: caso de las enfermedades cardiovasculares / Rationing, inflation and health inequity in Venezuela: case of cardiovascular diseases

los modelos público-sanitarios de caráctermonopólico como el venezolano, suelen asociarse a tendencias al racionamiento de los bienes y servicios que proveen a sus usuarios, así como a la merma de la calidad de estos. Por otro lado, la provisión de dichos bienes y servicios por la vía de mecanismos de mercado, tiene ante sí, el inconveniente que supone el ambiente inflacionario de su economía, cuyo impacto en los precios limita el acceso del paciente a su consumo. El caso de la enfermedad cardiovascular ofrece algunas claves para la comprensión de este fenómeno en el medio venezolano.

Public-health models of a monopolistic nature, suchas the Venezuelan, bring with them trends in the rationing ofthe goods and services they provide to their users, as well as inthe reduction of their quality. On the other hand, the provisionof these goods and services by means of market mechanisms hasbefore it, in our environment, the enormous impediment posedby the inflationary environment of its economy, whose impacton prices limits the patient's access to consumption. The case of cardiovascular disease offers some keys to understanding thisphenomenon in the Venezuelan environment.

Mortality from Cardiovascular Diseases: A Comparative Analysis between the Medical and Non-Medical Populations in Brazil

Abstract Background: Cardiovascular disease (CVD) is the leading cause of death worldwide, including among physicians. Professional peculiarities increase cardiovascular risk in this population, making it relevant to analyze mortality in the medical population (MPop) and non-medical population (NMPop). Objectives: To compare the CVD mortality coefficient (MC) in between MPop and NMPop in Brazil by analyzing the epidemiological profile and the main causes of deaths from CVD. Methods: Time-series study with data obtained from the Mortality Information System of the Federal Council of Medicine and the Brazilian Institute of Geography and Statistics, from 2014 to 2018. The variables age group, sex, race, occupation, and CVD that caused the death were assessed in MPop and NMPop. MC, relative risk and odds ratio between the populations were calculated. Tests for difference in proportions, with approximation to the normal distribution, and chi-squared tests were performed, assuming p<0.01 as statistically significant. Results: Both MPop and NMPop had a predominance of men (86.7% and 52.3%), senior citizens (85.9% and 79.7%) and white individuals (86.4% and 52.2%). The MCs of the MPop and NMPop was 92.2 and 255.1 deaths/100,000 individuals, respectively. The main cause of death was acute myocardial infarction (AMI) (32.5% and 24.6% in MPop and NMPop, respectively) followed by cerebrovascular accident (CVA) (5.1% and 10.5% in MPop and NMPop, respectively). Conclusion: In Brazil, mortality from CVD was more prevalent in white elderly males, and mainly caused by AMI and CVA. Being a doctor, man and over 60 years old represents a greater chance of death from CVD in comparison with non-physicians.

Cardioprotective Effects of Sodium-glucose Cotransporter 2 Inhibitors Regardless of Type 2 Diabetes Mellitus: A Meta-analysis

Abstract Background: Type 2 diabetes mellitus (T2DM) is an independent risk factor for cardiovascular impairment, increasing the rates of atherosclerotic and non-atherosclerotic events. Additionally, adverse kidney events are directly linked with T2DM and cardiovascular diseases. In this context, the sodium-glucose cotransporter 2 inhibitors (SGLT2i) have demonstrated both cardioprotective and renoprotective effects in patients with or without T2DM. Therefore, the present meta-analysis aims to evaluate cardiovascular outcomes involving SGLT2i as monotherapy or other add-on antidiabetic agents (ADA) in patients with or without T2DM. Objetive: The present meta-analysis aims to evaluate cardiovascular outcomes involving SGLT2i as monotherapy or add-on other ADA in patients with or without T2DM. Methods: The entrance criteria to SGLT2i studies were: describing any data regarding cardiovascular effects; enrolling more than 1,000 participants; being approved by either the FDA or the EU, and having available access to the supplementary data. The trial had to exhibit at least one of the following results: major adverse cardiovascular events (MACE), cardiovascular death or hospitalization for heart failure, cardiovascular death, hospitalization for heart failure, renal or cardiovascular adverse events, or non-cardiovascular death. The significance level of 0.05 was adopted in the statistical analysis. Results: Nine trials with a total of 76,285 participants were included in the meta-analysis. SGLT2i reduced MACE (RR 0.75, 95% CI [0.55-1.01]), cardiovascular death or hospitalization for heart failure (RR 0.72, 95% CI [0.55-0.93]), cardiovascular death (RR 0.66, 95% CI [0.48-0.91]), hospitalization for heart failure (RR 0.58, 95% CI [0.46-0.73]), renal or cardiovascular adverse events (RR 0.55, 95% CI [0.39-0.78]), and non-cardiovascular death (RR 0.88, 95% CI [0.60-1.00]). Conclusions: Conjunction overall data suggests that these drugs can minimize the risk of cardiovascular events, thus decreasing mortality in patients, regardless of the presence of T2DM.

Emergency Department Visits and Deaths from Cardiovascular Diseases at a Referral Center for Cardiology During the COVID-19 Pandemic

Abstract Background The COVID-19 pandemic has imposed measures of social distancing and, during this time, there has been an elevation in cardiovascular mortality rates and a decrease in the number of emergency visits. Objectives To assess and compare in-hospital mortality for cardiovascular diseases and emergency department visits during the COVID-19 pandemic and the same period in 2019. Methods Retrospective, single-center study that evaluated emergency visits and in-hospital deaths between March 16, 2020 and June 16, 2020, when the steepest fall in the number of emergency admissions for COVID-19 was registered. These data were compared with the emergency visits and in-hospital deaths between March 16 and June 16, 2019. We analyzed the total number of deaths, and cardiovascular deaths. The level of significance was set at p < 0.05. Results There was a 35% decrease in the number of emergency visits and an increase in the ratio of the number of deaths to the number of emergency visits in 2020. The increase in the ratio of the number of all-cause deaths to the number of emergency visits was 45.6% and the increase in the ratio of the number of cardiovascular deaths to the number of emergency visits was 62.1%. None of the patients who died in the study period in 2020 tested positive for COVID-19. Conclusion In-hospital mortality for cardiovascular diseases increased proportionally to the number of emergency visits during the COVID-19-imposed social distancing compared with the same period in 2019.

Tendência da mortalidade das doenças cardiovasculares, nas capitais brasileiras, no período entre 1990 e 2018 / Trends in mortality from cardiovascular diseases in brazilian capitals between 1990 and 2018

As doenças cardiovasculares (DCV) são a principal causa de morte no Brasil e no mundo. As doenças isquêmicas do coração (DIC) e doenças cerebrovasculares (DCBV) estão entre as dez principais causas de mortes no Brasil. A análise de tendência da mortalidade por DCV permite definir populações prioritárias para intervenções, elaborar e avaliar ações em saúde pública. Nesse sentido, o objetivo do estudo foi analisar a tendência da mortalidade por DIC e DCBV nas 27 capitais brasileiras, no período de 1990 a 2018. Trata-se de um estudo ecológico de série temporal, os dados de óbitos foram obtidos através do Sistema de Informações sobre Mortalidade (SIM). Buscando corrigir problemas na qualidade da informação dos registros de óbito do SIM, realizou-se a correção dos óbitos referentes aos dados com sexo e/ou faixa etária ignorada e aos óbitos registrados com causas "mal definidas". As taxas de mortalidade por DIC e DBCV foram padronizadas pelo método direto, tomando-se como população padrão a população do Brasil no ano de 2010. A análise de tendência da mortalidade por DIC e DCBV para a população total, homens e mulheres foi realizada utilizando o modelo de regressão de Poisson. Os resultados mostraram tendência de redução da mortalidade por DCBV tanto para a população total como para homens e mulheres em todas as capitais brasileiras. Vitória, capital da região Sudeste, apresentou a maior redução da taxa de mortalidade total por DCBV dentre todas as capitais brasileiras, -5,6% ao ano (IC95%: -6,0; -5,1%). No entanto, Macapá, capital da região Norte, teve a menor dentre todas as capitais -1,7% ao ano (IC95%: -2,7; -0,7%). Paras as DIC foi observada tendência de redução da mortalidade tanto para a população total como para homens e mulheres nas capitais das regiões Sul, Sudeste e para a maioria das capitais da região Centro-Oeste. As capitais das regiões Norte e Nordeste apresentaram uma variabilidade na tendência da mortalidade por DIC. Conclui-se que as capitais das regiões Sul e Sudeste apresentaram as maiores reduções da tendência da mortalidade por DIC e DCBV. Os achados desse estudo são importantes para prover informações mais detalhadas buscando auxiliar a gestão local na promoção de políticas de saúde pública, planejamento de estratégias e elaboração de medidas e ações em saúde.

Cardiovascular diseases (CVD) are the leading cause of death in Brazil and worldwide. Ischemic heart diseases (IHD) and cerebrovascular diseases (CBVD) are among Brazil's ten main causes of death. The trend analysis of mortality from CVD allows defining priority populations for interventions, designing and evaluating public health actions. In this sense, the study's objective was to analyze the mortality trend from IHD and CBVD in the 27 Brazilian capitals from 1990 to 2018. This is an ecological time-series study with the Mortality Information System (SIM) data. Seeking to correct the quality of the information in the SIM death records, the correction of deaths referring to data with anonymous sex and age group and deaths recorded with "ill-defined" causes was carried out. IHD and CBVD mortality rates were standardized by the direct method, using the population of Brazil in 2010 as the standard population. Trend analysis of IHD and CBVD mortality for the total population, men and women, was performed using the Poisson regression model. The results showed a reduction in the trend of mortality from CBVD for both the total population and for men and women in all Brazilian capitals. Vitória, the capital of the Southeast region, showed the greatest reduction in the total mortality rate from CVD among all Brazilian capitals, -5.6% per year (95%CI: -6.0; -5.1%). However, Macapá, the capital of the North region, had the lowest among all capitals -1.7% per year (95%CI: -2.7; -0.7%). For IHD, a decrease in the mortality trend was observed both for the total population and for men and women in the capitals of the South and Southeast regions and most capitals of the Center-West region. The capitals of the North and Northeast regions showed variability in the trend of IHD mortality. In conclusion, the capitals of the South and Southeast regions showed the greatest reductions in the mortality trend due to IHD and CBVD. The findings of this study are essential to provide more detailed information to assist local management in promoting public health policies, planning strategies, and designing health measures and actions.

¿El tratamiento del hipotiroidismo subclínico tiene efecto sobre la morbimortalidad cardiovascular? / Does treatment of subclinical hypothyroidism have an effect on cardiovascular morbidity and mortality?

Un estudio mostró que el aumento de valores de la hormona estimulante de la tiroides se asoció a un aumento de mortalidad por todas las causas, estimando que las enfermedades cardiovasculares mediaban dicha asociación en aproximada-mente el 14 % de los casos. Asimismo se observó que el reemplazo con levotiroxina disminuiría los niveles de colesterol, lo cual podría tener un efecto en la reducción de enfermedades cardiovasculares. Partiendo de una viñeta clínica la autora intenta, a través de una búsqueda bibliográfica y análisis de la evidencia, determinar si el tratamiento del hipotiroidismo subclínico en adultos mayores reduciría la morbimortalidad por eventos cardiovasculares. (AU)

A study showed that increased thyroid-stimulating hormone levels were associated with increased all-cause mortality, with cardiovascular disease estimated to mediate this association in approximately 14 % of cases. Additionally, levothyroxine replacement was found to lower cholesterol levels, which could have an effect in reducing cardiovascular diseases. Basedon a clinical vignette, the author attempts, through a literature search and an analysis of the evidence, to determine whether treatment of subclinical hypothyroidism in older adults would reduce morbidity and mortality from cardiovascular events.

Esta tese apresenta estudos sobre as características das ondas de calor e abordou seus efeitos nas doenças do aparelho circulatório nas capitais brasileiras no período de 2000 a 2016. O primeiro estudo teve como objetivo examinar a intensidade, a frequência e a duração dos eventos de ondas de calor nas capitais brasileiras, por meio das análises de séries temporais foi possível caracterizar a ocorrência das ondas de calor, os resultados mostraram que estão mais frequentes, duradouras e intensas e ocorrem durante todo o ano, inclusive no inverno em cidades das regiões Sudeste e Sul. O segundo estudo teve como objetivo identificar as capitais brasileiras que apresentaram desconforto térmico para população, por meio da caracterização do índice de calor. Os resultados mostraram que se utilizando as definições de temperatura aparente e conforto e desconforto térmico do diagrama do conforto humano, na maioria das capitais foram constatadas condições de desconforto para a saúde humana. Algumas capitais localizadas no Sudeste e no Sul apresentaram condições definidas por conforto térmico. O terceiro estudo teve como objetivo estimar os efeitos de ondas de calor na mortalidade do aparelho circulatório no município do Rio de Janeiro no ano de 2010. A análise de séries temporais foi utilizada para estimar o percentual do Risco Relativo (%RR) do efeito das ondas de calor na mortalidade de pessoas adultas a partir de ≥ 30 anos de idade. Os resultados deste estudo evidenciaram o aumento do %RR nas mortalidades por DAC associadas às ondas de calor no município do Rio de Janeiro. O quarto estudo teve como objetivo estimar os efeitos de ondas de calor na mortalidade por doenças do aparelho cardiovascular nas capitais brasileiras, a análise de séries temporais foi utilizada para estimar o percentual do Risco Relativo (%RR) do efeito das ondas de calor na mortalidade de pessoas adultas ≥ 30 anos de idade. Os resultados indicam uma associação entre ondas de calor e a mortalidade por doenças cerebrovasculares e doenças isquêmicas do coração na população adulta. Os achados deste conjunto de estudo permitem concluir que as ondas de calor estão mais frequentes, intensas e duradouras nas capitais brasileiras e, as doenças do aparelho circulatório estão associadas com este fenômeno.

Heat waves have been associated with circulatory disease morbidity and mortality in different locations, especially in groups considered vulnerable. This thesis present studies on the characteristics of heat waves and addressed its effects on circulatory diseases in Brazilian capitals from 2000 to 2016. The first study aimed to examine the intensity, frequency and duration of heat wave events in the Brazilian capitals, through temporal series analysis, it was possible to characterize the occurrence of heat waves, the results showed that they are more frequent, lasting and intense and occur throughout the year, including winter in cities in the Southeast and South regions. The second study aimed to identify the Brazilian capitals that presented thermal discomfort for the population, through the characterization of the heat index. The results showed that using the apparent temperature definitions and comfort and thermal discomfort of the human comfort diagram, most capitals were found conditions of discomfort for human health. Some capitals located in the Southeast and South had conditions defined by thermal comfort. The third study aimed to estimate the effects of heat waves on the mortality of the circulatory system in the municipality of Rio de Janeiro in 2010. Time series analysis was used to estimate the percentage of relative risk (%RR) of the effect of heat waves on adult mortality from ≥ 30 years of age. The results of this study showed the increase of %RR in DAC mortality associated with heat waves in the municipality of Rio de Janeiro. The fourth study aimed to estimate the effects of heat waves on mortality from cardiovascular disease in Brazilian capitals, timely series analysis was used to estimate the percentage of relative risk (%RR) of the effect of heat waves on mortality of adults ≥ 30 years of age. The results indicate an association between heat waves and mortality from cerebrovascular diseases and ischemic heart disease in the adult population. The findings of this study set allow you to conclude that heat waves are more frequent, intense and lasting in Brazilian capitals and circulatory diseases are associated with this phenomenon.

Riesgo cardiovascular global en tres casas de abuelos del municipio Boyeros / Global Cardiovascular Risk in three Elderly Homes from Boyeros Municipality

Introducción: En Cuba, las enfermedades cardiovasculares constituyen la primera causa de muerte. La estratificación del riesgo cardiovascular mediante escalas es un pilar fundamental para tomar decisiones terapéuticas en el primer nivel de atención. Objetivos: Determinar el riesgo cardiovascular global en personas mayores de 60 años de las tres casas de abuelos del municipio Boyeros, La Habana. Métodos: Se realizó un estudio observacional descriptivo de corte transversal. El universo de estudio lo constituyeron 130 personas pertenecientes a tres casas de abuelos del municipio Boyeros, La Habana. De ellas se entrevistaron a 103 de las personas en el período de enero del 2016 a febrero del 2017. Se realizó el cálculo del riesgo cardiovascular global siguiendo los criterios de las tablas de predicción del riesgo cardiovascular global de la Organización Mundial de la Salud. Las variables descriptivas se expresaron en porcentajes y para la comparación de dos variables en estudio se utilizó el método estadístico no paramétrico de Ji cuadrado con un nivel de significación de 0,05.

Introduction: In Cuba, cardiovascular diseases are the leading cause of death. Cardiovascular risk stratification by means of scores is a significant tool for making therapeutic decisions at the first level of healthcare. Objectives: To determine global cardiovascular risk in people older than sixty years from the three elderly homes of Boyeros Municipality, Havana. Methods: A descriptive, cross-sectional and observational study was carried out. The study universe was made up of 130 people belonging to three elderly homes from Boyeros Municipality, Havana. Of the participants, 103 were interviewed in the period from January 2016 to February 2017. Calculation of global cardiovascular risk was performed following the criteria of the World Health Organization's prediction tables for global cardiovascular risk. Descriptive variables were expressed in percentages, while, for the comparison of two variables under study, the nonparametric chi-square statistical method was used with a significance level of 0.05. Results: Of the people studied, 61.17 percent were female, 53.4percent were between aged 60-69 years, 65.05percent presented arterial hypertension, 47.57percent presented moderate risk, and 55.34percent had total cholesterol levels above 6 mmol/L. Conclusions: Moderate global cardiovascular risk predominated. Elevated blood pressure, diabetes mellitus and hypercholesterolemia were the modifiable risk factors most associated with increased overall cardiovascular risk(AU)

Enfermedad cardiovascular aterosclerótica según el sexo en personas de edad mediana con diabetes mellitus / Atherosclerotic cardiovascular disease according to sex in middle-aged people with diabetes mellitus

Introducción: El sexo influye en la susceptibilidad de las personas de ambos géneros con relación a la mayoría de las enfermedades comunes, incluidas la diabetes mellitus y la aterosclerosis. Objetivo: Identificar si existen diferencias en la presentación de la enfermedad cardiovascular aterosclerótica entre hombres y mujeres de edad mediana con diabetes mellitus. Métodos: Se realizó un estudio descriptivo de corte transversal en 1449 pacientes con diabetes mellitus en edad mediana (40 a 59 años) que ingresaron en el Centro de Atención al Diabético de Bayamo, Granma, desde el año 2010 al 2019. Se empleó la prueba de Chi Cuadrado para comprobar la relación entre las variables cualitativas, y T de Student para comparar los valores promedio de las variables cuantitativas. Resultados: La proporción de enfermedad cardiovascular aterosclerótica en el sexo masculino fue similar a la del femenino (51,4 por ciento x 48,6 por ciento, p=0.2328). No hubo discrepancias importantes en el porcentaje de la enfermedad, entre ambos sexos, en los diferentes grupos etarios. El riesgo de enfermedad cardiovascular aterosclerótica en los hombres fue mayor que en las mujeres premenopausicas (OR=2,19, IC: 1,4-3,3 p=0,0002), pero inferior respecto a las posmenopáusicas. (OR=1.12, IC: 0.8-1.4, p=0.4129). El análisis multivariado mostró al tiempo de la diabetes >10 años y a la hipertensión arterial como riesgo de enfermedad cardiovascular aterosclerótica en ambos sexos. Asimismo, se evidenció en la edad mayor de 45 años en los hombres (OR=2.5, IC: 1.4-4.6) y la menopausia en las mujeres (OR=1.8, IC: 1.1-3.07). Conclusiones: La frecuencia de la enfermedad cardiovascular aterosclerótica en las personas de edad mediana con diabetes mellitus es similar en ambos sexos. El sexo masculino tiene mayor riesgo de enfermarse que las mujeres premenopausicas, pero menor que las posmenopáusicas. La hipertensión arterial y el tiempo de la diabetes son factores de riesgo comunes para uno y otro sexo(AU)

Introduction: Sex influences the susceptibility of people of both genders to most common diseases, including diabetes mellitus (DM) and atherosclerosis. Objective: Identify if there are differences in the presentation of atherosclerotic cardiovascular disease between middle-aged men and women with diabetes mellitus. Methods: A descriptive cross-sectional study was conducted in 1449 patients with DM in middle age (40 to 59 years) who were admitted to the Diabetic´s Care Center of Bayamo, Granma province, from 2010 to 2019. The Chi-Square test was used to check the relation between the qualitative variables, and the T Student test to compare the average values of the quantitative variables. Results: The proportion of atherosclerotic cardiovascular disease in males was similar to that of females (51.4 percent x 48.6 percent, p=0.2328). There were no major discrepancies in the percentage of atherosclerotic cardiovascular disease, between both sexes, in the different age groups. The risk of atherosclerotic cardiovascular disease in men was higher than in pre-menopausal women (OR=2.19, CI: 1.4-3.3 p=0.0002), but lower than in post-menopausal women. (OR=1.12, CI: 0.8-1.4, p=0.4129). Multivariate analysis showed diabetes >10 years and arterial hypertension as a risk of atherosclerotic cardiovascular disease in both sexes. It was also evidenced in ages over 45 years in men (OR=2.5, CI: 1.4-4.6) and menopause in women (OR=1.8, CI: 1.1-3.07). Conclusions: The frequency of atherosclerotic cardiovascular disease in middle-aged people with diabetes mellitus is similar in both sexes. Males have a higher risk of atherosclerotic cardiovascular disease than pre-menopausal women, but lower than post-menopausal women. High blood pressure and diabetes time are common risk factors for both sexes(AU)

Complicaciones posquirúrgicas en pacientes con aneurisma de la aorta abdominal operados electivamente / Post-surgical complications in patients with electively operated abdominal aortic aneurysm

Introducción: Los aneurismas aórticos abdominales constituyen un problema de salud por la alta mortalidad que provocan. Su seguimiento y tratamiento son fundamentales para evitar las complicaciones posquirúrgicas. Objetivo: Caracterizar las principales complicaciones posquirúrgicas de los pacientes con aneurisma de la aorta abdominal operados electivamente. Métodos: Se realizó un estudio observacional y descriptivo en 94 pacientes operados de forma electiva en el Instituto Nacional de Angiología y Cirugía Vascular por presentar un diagnóstico de aneurisma de la aorta abdominal. Las variables de estudio fueron: edad, sexo, color de la piel, enfermedades asociadas, diámetro del aneurisma, profilaxis antibiótica, tiempo quirúrgico, tipo de prótesis vascular, tipo de complicación posoperatoria, tiempo de aparición de las complicaciones, estadía hospitalaria posoperatoria y estado al egreso. Se determinaron las frecuencias absolutas y relativas. Resultados: El 56,4 por ciento de los pacientes operados presentó algún tipo de complicación, las cuales fueron más frecuentes en el sexo masculino por encima de los 60 años. Las más predominantes resultaron la bronconeumonía (24,5 por ciento) y las arritmias cardíacas (20,8 por ciento). La proporción de complicaciones se mostró mayor en los pacientes con injertos bifurcados, así como en aquellos sin profilaxis y con un tiempo quirúrgico prolongado. Hubo mayor frecuencia de enfermedades cardiovasculares entre los fallecidos. Conclusiones: En los pacientes operados de forma electiva de aneurisma de la aorta abdominal predominaron las complicaciones respiratorias y cardiovasculares, estas últimas provocaron un aumento en la mortalidad(AU)

Introduction: Abdominal aortic aneurysms are a health problem because of the high mortality they cause. Their follow-up and treatment are essential to avoid post-surgical complications. Objective: Characterize the main post-surgical complications of patients with electively operated abdominal aortic aneurysm. Methods: An observational and descriptive study was conducted in 94 electively operated patients at the National Institute of Angiology and Vascular Surgery after having a diagnosis of abdominal aortic aneurysm. The study variables were: age, sex, skin color, associated diseases, aneurysm diameter, antibiotic prophylaxis, surgical time, type of vascular prosthesis, type of postoperative complication, time of onset of complications, postoperative hospital stay, and state at discharge moment. Absolute and relative frequencies were determined. Results: 56.4 percent of operated patients had some form of complication, which were more common in the males over 60 years. The most predominant complications were bronchopneumonie (24.5 percent) and cardiac arrhythmias (20.8 percent). The proportion of complications was shown to be higher in patients with forked grafts, as well as in those without prophylaxis and with prolonged surgical time. There was a higher frequency of cardiovascular diseases among the deceased patients. Conclusions: In patients electively operated of abdominal aortic aneurysm, there was a predominance of respiratory and cardiovascular complications, and the latter caused an increase in mortality(AU)

Cardiovascular Risk Factors in Patients with Chronic Kidney Disease Under Conservative Treatment

Abstract Background Cardiovascular disease (CVD) is commonly associated with chronic kidney disease (CKD). These diseases have a significant impact on life expectancy. Individuals with CKD are more likely to die from CVD than to progress to end-stage kidney disease. Objective To assess cardiovascular risk factors of patients with CKD under conservative treatment. Methods This was an observational, cross-sectional study. Socioeconomic, anthropometric, biochemical, and physical inactivity data were assessed, and 10-year risk for CVD were estimated using the Framingham Score in patients with CKD under conservative treatment. For statistical analysis, the Student's t-test and Pearson's chi-square test were performed. Results A total of 172 individuals were evaluated, 57% of whom were male, with an average age of 68.85 ± 11.41 years. The prevalence of hypertension and diabetes were 87.2% and 53.5%, respectively; 62.2% were physically inactive; 9.9% of men were smokers and 12.8% consumed alcohol. According to BMI, 82.4% of adults <60 years old and 60.6% of those older than 60 years were overweight. High waist circumference and a high waist-hip ratio were highly prevalent in females (91.9% and 83.8%, respectively) and males (64.3% and 39.8%, respectively); 92.4% had a high body fat percentage and 73.3% high uric acid levels. According to the Framingham score, 57% have a medium or high risk of developing CVD in 10 years. Conclusion There was a high prevalence of cardiovascular risk factors in the population studied. The assessment of cardiovascular risk factors in patients with CKD makes it possible to guide the conduct of health professionals to prevent mortality from cardiovascular causes.

Seasonality of mortality under a changing climate: a time-series analysis of mortality in Japan between 1972 and 2015

BACKGROUND@#Ambient temperature may contribute to seasonality of mortality; in particular, a warming climate is likely to influence the seasonality of mortality. However, few studies have investigated seasonality of mortality under a warming climate.@*METHODS@#Daily mean temperature, daily counts for all-cause, circulatory, and respiratory mortality, and annual data on prefecture-specific characteristics were collected for 47 prefectures in Japan between 1972 and 2015. A quasi-Poisson regression model was used to assess the seasonal variation of mortality with a focus on its amplitude, which was quantified as the ratio of mortality estimates between the peak and trough days (peak-to-trough ratio (PTR)). We quantified the contribution of temperature to seasonality by comparing PTR before and after temperature adjustment. Associations between annual mean temperature and annual estimates of the temperature-unadjusted PTR were examined using multilevel multivariate meta-regression models controlling for prefecture-specific characteristics.@*RESULTS@#The temperature-unadjusted PTRs for all-cause, circulatory, and respiratory mortality were 1.28 (95% confidence interval (CI): 1.27-1.30), 1.53 (95% CI: 1.50-1.55), and 1.46 (95% CI: 1.44-1.48), respectively; adjusting for temperature reduced these PTRs to 1.08 (95% CI: 1.08-1.10), 1.10 (95% CI: 1.08-1.11), and 1.35 (95% CI: 1.32-1.39), respectively. During the period of rising temperature (1.3 °C on average), decreases in the temperature-unadjusted PTRs were observed for all mortality causes except circulatory mortality. For each 1 °C increase in annual mean temperature, the temperature-unadjusted PTR for all-cause, circulatory, and respiratory mortality decreased by 0.98% (95% CI: 0.54-1.42), 1.39% (95% CI: 0.82-1.97), and 0.13% (95% CI: - 1.24 to 1.48), respectively.@*CONCLUSION@#Seasonality of mortality is driven partly by temperature, and its amplitude may be decreasing under a warming climate.
