Review Meta Analysis
Use of smokeless tobacco and risk of cardiovascular disease: A systematic review and meta-analysis.
Objective The purpose of this study was to assess the risk of ischaemic heart disease (IHD) and stroke (non-fatal and fatal) among adult ever-users of smokeless tobacco (ST). Design The study design involved a systematic review and meta-analysis of observational studies. Methods Data sources for the review included key electronic databases and reference lists. ⋯ European studies did not show an increased risk for non-fatal CVD. Conclusion An association was found between ever use of ST and risk of fatal IHD and stroke, consistent with previous reviews. ST consumption also appears to significantly increase risk of non-fatal IHD among users in Asia, but not in Europe.
