Coronary artery diseaseInfluence of Socioeconomic Status on Lifestyle Behavior Modifications Among Survivors of Acute Myocardial Infarction
Section snippets
Methods
The study is a substudy of the Socio-Economic and Acute Myocardial Infarction Study (SESAMI) study, a prospective observational study of patients hospitalized for AMI throughout Ontario, Canada.7 Data came from (1) a baseline survey, (2) chart abstraction from the index AMI, (3) a 1-month follow-up telephone survey, and (4) linked health administrative data. The study received research ethics approval at each participating institution.
Of the 2,696 consecutive patients who were alive and
Results
The mean age of the cohort was 62.6 ± 12.8 years; 28.2% were women. Compared with their wealthier or higher-educated counterparts, lower-income and educated patients were older, more often non-Caucasian, had greater baseline cardiovascular risk (i.e., as measured using GRACE), and had more pre-existing co-morbid conditions (Table 1).
In our cohort, 30.3% acknowledged that they were smokers at baseline (i.e., ascertained at time of index AMI hospitalization). Of these smokers, 29.4% stated they
Discussion
Our study demonstrated that socioeconomically disadvantaged patients were less likely to modify or adapt to healthier lifestyle behaviors during the early convalescent periods after AMI than were those of higher SES despite having poorer prognosis and greater illness severity at baseline. In particular, poorer patients reported lower propensities to stop or decrease smoking and/or alcohol consumption and were less likely to partake in regular exercise during the weeks after AMI
