Liu YH, Wang SQ, Xue JH, Liu Y, Chen JY, Li GF, Tan N - BMC Cardiovasc Disord (2015)

Bottom Line: Sixty-seven percent were published during 2006-2009.Leading general medical journals Journal of the American Medical Association (n = 1), Lancet (n = 0) and New England Journal of Medicine (n = 0) featured only 1 published article, despite their extremely high impact factors.Clinical researches had the highest mean citations (mean 102.6 citations per article).

ABSTRACT

Background: China, as a rapidly developing country with the largest population of cardiologist in the world, has an increasing importance in the field of cardiology. However, the quantity and quality of research production in the field of cardiology is unclear.

Aims: To analyze the characteristics of the high-level articles published on cardiovascular diseases in Mainland China, and to provide information about achievements and development in cardiovascular research.

Methods: We searched the Science Citation Index Expanded for citations of cardiovascular articles originating in mainland China from 2004 to 2015. For the 100 most frequently cited articles (T100), we evaluated the number of citations, publication time, province of origin, journal, impact factor, topic or subspecialty of the research, and publication type.

Results: The most frequently cited article received 703 citations at the most, while 50 at the least (mean 91.6 citations per article). T100 originated from 16 provinces, the plurality (n = 34) being from the Beijing. Sixty-seven percent were published during 2006-2009. The publications were in 29 different journals of which Circulation published the most (n = 14). Leading general medical journals Journal of the American Medical Association (n = 1), Lancet (n = 0) and New England Journal of Medicine (n = 0) featured only 1 published article, despite their extremely high impact factors. Of the T100 articles, there were 50 basic researches, 44 clinical researches, 5 meta-analyses and 1 review article. Clinical researches had the highest mean citations (mean 102.6 citations per article).

Conclusions: This study provides a historical perspective on the scientific progress, and the trends in cardiovascular medicine in Mainland China.

Mentions: The analysis of the design of the T100 articles found that they included 6 meta-analyses and 1 review, whereas the majority of the article types were basic science studies (50 articles), followed by clinical trials (43 articles) (Fig. 3). Among the 43 clinical articles, 13 were randomized clinical trials and 30 were observational trials. As shown in Fig. 4, these clinical trials were mainly focused on coronary artery disease (21 studies, including 6 on acute coronary syndromes), epidemiology (4 studies), arrhythmia (4 studies), cardiac surgery (3 studies), heart failure (2 studies), hypertension (2 studies), congenital heart disease (1 study), or other topics (6 studies). In terms of time, 5 earliest clinical researches which were published in 2004 were cited the most (239 times per article), while 3 earliest basic researches in 2004 were cited the most (110 times per article) (Fig. 5).Fig. 3
