Dietary atherogenicity and thrombogenicity indexes predicting cardiovascular mortality : 50-year follow-up of the Seven Countries Study
Background and aim: To study the relationships of an Atherogenicity Index (ATI) and a Thrombogenicity Index (THI), with 50-year mortality from coronary heart disease (CHD), other heart diseases of uncertain etiology (HDUE) and cerebrovascular disease or stroke (STR), in 16 international cohorts of middle-aged men. Methods and results: Foods from a dietary survey in subsamples of men in each cohort of the Seven Countries Study (SCS) were chemically analyzed for several types of fatty acids that were converted into ATI and THI identifying each of 16 cohorts. Ecological correlations of the ATI and THI were calculated with the three fatal CVD conditions and with all-cause mortality at 25 and 50 years. Correlation coefficients (Rs) were positive and highly significant between ATI and THI versus CHD mortality, with levels ranging from 0.79 to 0.97, depending on the duration of follow-up and the choice of 10 or of 16 cohorts. This was not the case for HDUE and STR mortality for which Rs were variable and not significant. A strong direct association was also found with all-causes deaths at 25 and 50-years. ATI and THI were also directly related with dietary saturated fat and cholesterol levels and inversely with the Mediterranean Adequacy Index (a score identifying the Mediterranean diet). Conclusion: These findings indicate that CHD has a different relationship with dietary lipids intake than HDUE and STR. This suggests that HDUE and STR have different underlying pathways or are different diseases.
