Although fast food is affordable and convenient, it is also high in calories, saturated fat, and sodium. The frequency of fast food intake at the time of and after acute myocardial infarction (AMI) is modifiable. However, patterns of fast food intake and characteristics associated with its consumption in patients with AMI are unknown. The aim of this study was to study fast food consumption at the time of AMI and 6 months later in 2,481 patients from the prospective, 24-center Translational Research Investigating Underlying Disparities in Acute Myocardial Infarction Patients' Health Status (TRIUMPH) study of patients with AMI. Fast food intake was categorized as frequent (weekly or more often) or infrequent (less than weekly). Multivariate log-binomial regression was used to identify patient characteristics associated with frequent fast food intake 6 months after AMI. At baseline, 884 patients (36%) reported frequent fast food intake, which decreased to 503 (20%) 6 months after discharge (p <0.001). Male gender, white race, lack of college education, current employment, and dyslipidemia were independently associated with frequent fast food intake 6 months after AMI. In contrast, older patients and those who underwent coronary bypass surgery were less likely to eat fast food frequently. Documentation of discharge dietary counseling was not associated with 6-month fast food intake. In conclusion, fast food consumption by patients with AMI decreased 6 months after the index hospitalization, but certain populations, including younger patients, men, those currently working, and less educated patients were more likely to consume fast food, at least weekly, during follow-up. Novel interventions that go beyond traditional dietary counseling may be needed to address continued fast food consumption after AMI in these patients.
