Cardiac Involvement in COVID-19: A Global Bibliometric and Visualized Analysis

Area of Science:

• Cardiology
• Infectious Diseases
• Bibliometrics

Background:

• Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, has led to significant global mortality.
• Cardiac dysfunction is a known complication of COVID-19, but the mechanisms remain unclear.
• Understanding the research landscape of COVID-19's cardiac impact is essential.

Purpose of the Study:

• To conduct a bibliometric analysis of studies investigating cardiac involvement following SARS-CoV-2 infection.
• To identify key research trends, influential publications, and collaboration patterns in this field.

Main Methods:

• A comprehensive literature search was performed using the Web of Science database.
• Bibliometric indicators including publication types, countries, institutions, journals, and citation patterns were analyzed.
• VOSviewer software was utilized for qualitative and quantitative evaluations and visualization of scientific output.

Main Results:

• The analysis covered 2,025 documents on COVID-19 and cardiac involvement.
• The United States, Italy, and England were the most prolific countries in publishing research.
• Myocarditis and heart failure (HF) emerged as the primary research hotspots concerning COVID-19's impact on cardiac function.

Conclusions:

• This is the first bibliometric analysis focusing on COVID-19-associated cardiac disorders.
• The study offers valuable insights into influential research on COVID-19 and cardiac dysfunction.
• Enhanced international and institutional collaboration is recommended for research on myocarditis and heart failure during the COVID-19 pandemic.
