Death rate dramatically less for young heart attack survivors who quit smoking

The rate of heart attacks is continuing to increase among individuals younger than 50 years old. While the protective effects of quitting smoking are well documented among older individuals who have experienced a heart attack, the benefits have not been well studied among younger heart attack survivors. In a study published this week in JAMA Network Open, investigators from Brigham and Women's Hospital share results from a study of the association between quitting smoking and survival among young adults who have survived a heart attack. Based on a retrospective analysis of data from the Partners YOUNG-MI registry, the team found that about half of individuals who experienced a heart attack before age 50 were active smokers. Among those who quit within a year of their first heart attack, rates of death from heart disease or any cause of death were more than 70 percent lower than among those who did not quit.
