The characteristics and regularities of cardiac adverse drug reactions induced by Chinese materia medica: A bibliometric research and association rules analysis

Abstract Ethnopharmacological relevance Chinese materia medica (CMM) has been widely used as an approach of ethnomedicine worldwide. Recently, there are growing concerns related to the potential cardiotoxicity of herbal medicines but comprehensive studies are limited. Methods Comprehensive literature retrieval via publicly available electronic databases was performed to identify the case reports that focused on cardiac adverse reactions (ADRs) triggered by oral CMMs. And a bibliometric survey was conducted to analyze the most commonly suspected risk factors in terms of responsible CMMs, susceptible patients and clinical administration of cardiac ADRs. Moreover, the techniques of data mining were utilized to investigate the regularities and association between the ADRs status and major contributory factors. Results The available evidence of current research indicated that many influential factors were strongly associated with cardiac ADRs caused by oral CMMs inevitably, including pediatric patients, poisonous CMMs (especially herbs of Aconitum species), overdose and self-medication. Specifically, the timely and effective resuscitation could attribute their favorable capacity to reduce mortality for cardiac ADRs. Notably, the cardiac ADRs cases had often concomitant the ADRs of the nervous system and digestive system. Conclusion The comprehensive features and risk factors of cardiac ADRs induced by oral CMMs can be discovered and elucidated through the approaches of bibliometric research, association rules analysis, and data mining technology, which raise the profile and awareness of the rational applications of CMMs and pharmacovigilance within relevant heart side effects.
