RESUMO
Introduction: We analyze the scientific production and collaboration networks of studies based on adaptation and altitude diseases in the period 1980-2020. Methods: The publications were extracted from journals indexed in Scopus. The bibliometric analysis was used to analyze the scientific production, including the number of annual publications, the documents, and the characteristics of the publications. With the VOSviewer software, the analysis of collaborative networks, productivity of the countries, as well as the analysis of the co-occurrence of keywords were visualized. Results: 15,240 documents were registered, of which 3,985 documents were analyzed. A significant trend was observed in the number of publications (R 2: 0.9847; P: < 0.001), with annual growth of 4.6%. The largest number of publications were original articles (77.8%), these published more frequently in the journal "Altitude Medicine and Biology". The largest number of countries were from Europe and Asia; however, the largest collaboration network was with the United States. Of the countries with high altitudes, China and Peru ranked first in scientific productivity. The research priorities were on the adaptation mechanism (37.1%), mainly anoxia and respiratory function. Acute mountain sickness (18.4%) and pulmonary edema (14.7%) were the most reported diseases. Of the top 10 institutions, "University of Colorado" and "Universidad Peruana Cayetano Heredia" contributed more than 100 publications. Conclusions: Scientific production on adaptation and altitude illnesses continues to grow. The United States and United Kingdom present collaborative networks with high-altitude countries. The research is aimed at studying the mechanisms of adaptation to altitude and acute mountain sickness.

RESUMEN Objetivo: describir la función cardiovascular y determinar las alteraciones cardiacas en pacientes con y sin eritrocitosis excesiva (EE). Materiales y métodos: estudio de tipo prospectivo, transversal y analítico. La muestra fue de 61 pacientes residentes del Centro Poblado La Rinconada, localizado en Puno - Perú, ubicado a 5 200 m.s.n.m. Se utilizó una ficha de recolección de datos, se aplicó el score de mal de montaña crónico de Qinghai y un cardiólogo experimentado realizo las ecocardiografías. Resultados: el promedio de edad fue de 44 ± 7 años y el tiempo de residencia fue de 16 ± 9,8 años. Del total de pacientes, el 80,3% presentó mal de montaña crónico; de estos, el 68,9% fue de grado leve, 6,6% de grado moderado y el 4,9% de grado severo. Dentro de los hallazgos ecocardiográficos se encontraron: dilatación de cavidades cardiacas (16,4%), leve alteración del llenado del ventrículo derecho (3,27%), válvula aórtica bicúspide (3,27%), dificultad del llenado del ventrículo izquierdo (8,2%), leve alteración en la relajación y llenado del ventrículo izquierdo (1,6%), insuficiencia aórtica leve (1,6%) e hipertensión pulmonar (1,6%). El 83,6% presentaba hemoglobina ≥ 21 mg/dl. Conclusiones: el grupo con EE presentó más alteraciones cardiacas, la alteración cardiaca más frecuente fue la dilatación de cavidades cardiacas derechas.
ABSTRACT Objective: to describe cardiovascular function and determine cardiac disturbances in patients with and without excessive erythrocyteosis (EE). Materials and methods: a prospective, transversal and analytical type study. The sample was of 61 resident patients of the Centro Poblado La Rinconada, located in Puno - Peru, located at 5,200 meters above the sea level. A data collection sheet was used, Qinghai's chronic mountain sickness score was applied, and an experienced cardiologist performed echocardiographies. Results: the average age was 44 ± 7 years and the residence time was 16 ± 9.8 years. Of the total number of patients, 80.3% had chronic mountain sickness; of these, 68.9% were mild grade, 6.6% moderate grade and 4.9% severe grade. Among the echocardiographic findings were found: dilation of cardiac cavities (16.4%), slight alteration of the filling of the right ventricle (3.27%), bicuspid aortic valve (3.27%), difficulty filling the left ventricle (8.2%), slight alteration in relaxation and filling of the left ventricle (1.6%), mild aortic insufficiency (1.6%) pulmonary hypertension (1.6%). 83.6% had hemoglobin ≥ 21 mg/dL. Conclusions: the group with EE had more cardiac disturbances, the most common cardiac disturbance was the dilation of right heart chambers.
