Smoking Cessation and Mortality from Aortic Dissection and Aneurysm : Findings from the Japan Collaborative Cohort (JACC) Study

AIMS: Active cigarette smoking was intensively reported to increase the risk of aortic mortality while research on the association between smoking cessation and aortic mortality remains scarce. This study aimed to reconfirm the associations of exposure to cigarettes and smoking cessation associated with aortic mortality in a large Japanese population.

METHODS: In the Japan Collaborative Cohort (JACC) Study, 91,141 residents (57±10 years; men, 43%) who were free of stroke, coronary heart disease, and cancer were followed up from 1989-90 until 2009 during which 110 deaths from aortic dissection and 112 deaths from aneurysm were identified. Cox proportional hazard model was used to estimate multivariable hazard ratios (95%CI) for total and specific aortic mortality.

RESULTS: Compared to never smoking, HRs for total aortic mortality were 2.39 (1.40-4.08) for <20, 3.57 (2.19-5.83) for 20-39, and 3.92 (2.37-6.48) for ≥ 40 pack-years exposure. Compared to current smoking, HRs for total aortic mortality were 0.42 (0.18-0.97) for 10-15 years, 0.27 (0.11-0.66) for >15 years of cessation, and 0.24 (0.13-0.44) for never smoking. Similar inverse dose-response pattern was observed between smoking cessation duration and risk of mortality from aortic aneurysm (p for trend=0.001), but the association with aortic dissection mortality did not reach statistical significance.

CONCLUSIONS: Cigarette smoking was associated with an increased risk of aortic mortality while smoking cessation was so with a reduced risk among the Japanese population.
