Notes

  • BackgroundSnus, a Swedish type of smokeless tobacco, has potent acute hemodynamic effects, which could provoke stress on the cardiovascular system, including the myocardium. Snus has, however, not been linked to risk of ischemic heart disease. Therefore, we hypothesized that snus use increases the risk for heart failure of non-ischemic origin.MethodsWe conducted a pooled analysis of eight Swedish prospective cohort studies involving individual participant data from 350,711 men. Shared frailty models with random effects at the cohort level, were used to estimate hazard ratios (HRs) with 95 % confidence intervals (CIs) of heart failure in relation to snus use. We investigated dose-response associations, and association with ischemic and non-ischemic heart failure in separate. For positive control purposes, we also investigated associations between smoking and risk of heart failure.ResultsDuring a median follow-up time of 16 years, 5,404 men were hospitalized for heart failure. In models adjusting for age, smoking, previous myocardial infarction and educational level, current snus use was associated with a higher risk of heart failure (HR 1.27, 95 % CI 1.07-1.50), relative to non-current snus use. A dose-response pattern was observed, with higher risk with more snus cans used per week. We observed an association of snus use with non-ischemic heart failure, HR 1.34 (95 % CI 1.11-1.63), but not with ischemic heart failure, HR 1.01 (95 % CI 0.72-1.42). Smoking was more strongly associated with heart failure, particularly of ischemic origin, than snus use.ConclusionsSnus use was associated with a modestly increased risk for heart failure of non-ischemic origin in a dose-response manner. This finding has public health implications for the risk assessment of snus use, and potentially other modes of smokeless use of nicotine.
