Non-smokers lived 8.66 years (men) and 7.59 years (women) longer than smokers, and had more years free of cardiovascular disease, but ultimately spent more years living with the disease.
Cohort (n=4,723)
Mean Difference: 8.66 (95% CI 7.61–9.63)
AIMS: To compare the burden of cardiovascular disease in terms of lifetime risk and life years lived with disease between smokers and non-smokers. METHODS AND RESULTS: We constructed multi-state life tables describing transitions through various cardiovascular diseases for 4723 smokers and non-smokers observed during 20 biannual observations in the Original Framingham Heart Study. Non-smokers live 8.66 (95% CI 7.61-9.63) (men) and 7.59 (95% CI 6.33-8.92) (women) years longer than smokers and more years free of cardiovascular disease: 6.22 (95% CI 5.09-7.30) years for males and 4.93 (95% CI 3.54-6.29) for females. But non-smokers spend more years with cardiovascular disease over the life course: 2.43 (95% CI 1.72-3.16) years for males and 2.66 (95% CI 1.87-3.38) years for females. The risk of cardiovascular disease before age 70 is higher among smokers, but over the entire lifecourse male non-smokers have higher risks of coronary heart disease, myocardial infarction, stroke and congestive heart failure, and female non-smokers have higher risks of coronary heart disease and congestive heart failure. CONCLUSION: Smoking, by shortening life, decreases both the probability and duration of cardiovascular disease throughout the life course. Non-smokers live many years longer and longer free of cardiovascular disease than smokers, but at the end of their life non-smokers will have lived longer with cardiovascular disease.
Abdullah Al Mamun (Mon,) conducted a cohort in Cardiovascular disease (n=4,723). Smoking vs. Non-smokers was evaluated on Additional life years lived (men) (8.66 years, 95% CI 7.61-9.63). Non-smokers lived 8.66 years (men) and 7.59 years (women) longer than smokers, and had more years free of cardiovascular disease, but ultimately spent more years living with the disease.
