Dietary Fibre Intake & Mortality among Survivors of Myocardial Infarction

Research Paper Title

Dietary Fiber Intake and Mortality among Survivors of Myocardial Infarction: Prospective Cohort Study.

Study Question

What are the associations of dietary fibre post-myocardial infarction (MI) and changes of dietary fibre from before to after MI with all cause and cardiovascular mortality?

Summary Answer

In this prospective study of dietary fibre intake after MI, a greater intake of dietary fibre, especially cereal fibre, was inversely associated with all cause mortality. On average, participants increased dietary fibre intake after MI, and the greater the increase, the lower was the risk of subsequent all cause and cardiovascular mortality.

What is Known and What This Paper Adds

Dietary fibre is associated with a lower risk of coronary heart disease in healthy populations but it is unclear whether higher consumption of dietary fibre after MI is associated with lower mortality. In this prospective study of survivors after MI, a greater post-MI intake of dietary fibre, espcecially cereal fibre, was inversely associated with all cause mortality, and an increase in consumption of fibre from the period before to after MI was significantly associated with lower all cause and cardiovascular mortality.
