Equity and representation in cardiology research: A comprehensive analysis of authorship from low and low-middle income countries in cardiology journals.

Cardiovascular disease is the leading cause of mortality, disproportionately affecting low-income and low-middle-income countries (LICs/LMICs). Despite this, cardiology research commonly comes from affluent regions. This study assessed the authorship trends from LICs/LMICs in cardiology journals listed in PubMed from 2000 to 2022.
