- Abstract
Background: Some observational studies and randomised controlled trials (RCTs) have reported an association between calcium supplementation and increased risk of cardiovascular disease. Previous meta-analyses on the topic, based on data from RCTs and observational studies, have contradictory findings. This meta-analysis was conducted to determine the difference in associated risks of calcium supplementation with cardiovascular disease and stroke in RCTs., Methods: Relevant studies published from database inception to 6 August 2021 were sourced from PubMed, Embase, Scopus, and the Cochrane Central Register of Controlled Trials. Any RCTs focusing on the relationship between calcium supplementation and incidence of cardiovascular disease or stroke were included. Articles were screened independently by two authors, according to the PICO criteria, with disagreements resolved by a third author., Results: Twelve RCTs were included in the meta-analysis. Calcium supplementation was not associated with myocardial infarction, total stroke, heart failure admission, and all-cause/cardiovascular mortality. Subgroup analysis focusing on calcium monotherapy/calcium co-therapy with vitamin D, female sex, follow-up duration, and geographical region did not affect the findings., Conclusion: Calcium supplementation was not associated with myocardial infarction, total stroke, heart failure admission, and cardiovascular/all-cause mortality. Further studies are required to examine and understand these associations., (Copyright © 2023 Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) and the Cardiac Society of Australia and New Zealand (CSANZ).
