Current smoking was associated with a threefold increase in the risk of sudden cardiac death (RR 3.06) compared to never smoking.
Meta-Analysis
Effect estimate: RR 3.06 (95% CI 2.46-3.82)
= 0.30). The results persisted in most of the subgroup analyses. There was no evidence of publication bias. These results confirm that smoking increases the risk of sudden cardiac death. Any further studies should investigate in more detail the effects of duration of smoking, number of cigarettes per day, pack-years, and time since quitting smoking and sudden cardiac death.
Aune et al. (Wed,) conducted a meta-analysis in Sudden cardiac death. Current smoking vs. Never smokers was evaluated on Sudden cardiac death (RR 3.06, 95% CI 2.46-3.82). Current smoking was associated with a threefold increase in the risk of sudden cardiac death (RR 3.06) compared to never smoking.
