Pulmonary Hypertension: Classification and Pathogenesis

751
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Area of Science:

  • Bibliometrics and Scientometrics
  • Cardiovascular Research
  • Public Health

Background:

  • Pulmonary hypertension (PH) is a critical condition affecting lung circulation.
  • Despite extensive research, a comprehensive analysis of global PH research activity is lacking.
  • Understanding global research trends is crucial for advancing PH understanding and treatment.

Purpose of the Study:

  • To conduct a large-scale scientometric analysis of global research on pulmonary hypertension (PH).
  • To map the research landscape and identify key contributors and trends in PH research.
  • To analyze research output, citation rates, and international collaborations over distinct periods.

Main Methods:

  • Bibliometric data on PH publications were retrieved from the Web of Science database.
  • Data were analyzed for two periods: 1900–2007 (t1) and 2008–2015 (t2).
  • Density-equalizing maps and scientometric indicators (e.g., h-index, citation rates) were employed for analysis.

Main Results:

  • The US dominated publication output in both periods, followed by the UK and Germany.
  • China emerged as a significant contributor in the later period (t2), ranking fifth.
  • Mexico and Ireland showed the highest average citation rates in t1 and t2, respectively.
  • US research maintained a leading position based on the country-specific h-index.
  • International collaborations in PH research significantly increased over time, with the US leading.

Conclusions:

  • This study provides the first comprehensive scientometric mapping of global PH research.
  • The findings reveal the evolving global research architecture in pulmonary hypertension.
  • There is a need for targeted research programs in countries with lower human development indices to address global health disparities in PH.
