Disparities in Cardiovascular Research Output and Disease Outcomes among High-, Middle- and Low-Income Countries – An Analysis of Global Cardiovascular Publications over the Last Decade (2008–2017)

Abstract: Background: Cardiovascular disease (CVD) is the leading cause of death and disability worldwide. Health research is crucial to managing disease burden. Previous work has highlighted marked discrepancies in research output and disease burden between high-income countries (HICs) and low-and lower-middle-income countries (LI-LMICs) and there is little data to understand whether this gap has bridged in recent years. We conducted a global, country level bibliometric analysis of CVD publications with respect to tren… Show more

“…El presente estudio buscó determinar la producción científica (con más del 80% de la producción científica) comparado con los países de medianos y altos ingresos (16,1%), medianos y bajos ingresos (2,6%) y bajos ingresos (0,2%) (4) . La región de Latinoamérica y el Caribe publicó el 4% de artículos comparado con los países de altos ingresos como Estados Unidos y Canadá;…”

“…La investigación científica es un mecanismo para estudiar y mejorar la salud de las poblaciones, y frenar el incremento de la carga de las enfermedades crónicas no transmisibles mediante los principios de la medicina basada en evidencia, elaboración de políticas públicas y asignación de fondos nacionales e internacionales (4) . Sin embargo, los países de medianos y bajos ingresos tienen los mayores desafíos debido a la escasez de información basada en la evidencia, a la calidad y por restricciones en el uso de bases de datos en salud y la asignación de recursos para la investigación (4)(5)(6) lo cual genera una baja producción científica sobre ECV (7) .…”

“…Cardiovascular diseases (CVDs) have persistently been the principal cause of disease burden and mortality throughout the world as well as in Latin America (LATAM) [ 1 , 2 ] . Congruently, as CVDs continue to grow, the research production in this discipline has followed the same trend; global CVD publications have been increasing in the last decades [ 3 , 4 ] . However, as with other health-related topics, disparities in the quantity of research exist when comparing low- and middle-income countries with high-income nations [ 3 , 4 ] .…”

“…There are multiple benefits of developing local and regional research such as obtaining truthful information about CVDs as well as identifying the needs in healthcare or research [ 6 ] , but most importantly, there has been described an inverse relationship between the number of publications and cardiovascular burden [ 4 ] . In other words, research output may be related to an improvement in CVD-associated death rates and disability-adjusted life years [ 4 ] , which should be the most important motivator for researchers.…”
