The cardiovascular system at high altitude: A bibliometric and visualization analysis

Table 12 Critical aspects of the cardiovascular system at high altitude

Rank	Keyword	Significant points
1	Hypoxia	Hypoxia emerges as the predominant characteristic among individuals residing at high altitudes
2	Exercise at high altitude	Exercise training is advocated for enhancing adaptation to high altitude
3	Pulmonary hypertension	Pulmonary artery pressure increases at high altitude due to vasoconstriction
4	Oxidative stress	Oxidative stress is activity at high altitude
5	Metabolomics	Metabolomics has offered novel perspectives on the pathophysiological mechanisms that underlie adaptations to early hypobaric hypoxia, as well as other diseases associated with tissue hypoxia
6	Adaptation/acclimatization	Adaptation or acclimatization occurs in individuals residing at high altitudes for extended periods, including indigenous populations
7	Echocardiography	Echocardiography serves as a valuable diagnostic tool for identifying cardiac diseases in high-altitude environments
