Hot topics and trends in cardiovascular research.

ABSTRACT:

Aims

Comprehensive data on research undertaken in cardiovascular medicine can inform the scientific community and can support policy building. We used the publication output from 2004 to 2013 and the 2014 references to these documents, to identify research topics and trends in the field of cardiovascular disease.

Methods and results

Text fragments were extracted from the titles and abstracts of 478 000 publications using natural language processing.

Experts named the topics and document clusters based on various outputs from these semi-automatic metho
