Key result
In post-MI patients, higher education and rehabilitative therapy were associated with increased low-dose aspirin usage, whereas each 1-year increase in age significantly decreased usage by 2%.

What sociodemographic and clinical factors predict the usage of low-dose aspirin in post-myocardial infarction patients?
May help target adherence interventions in post-MI patients; leaves open whether addressing predictors improves outcomes.
BACKGROUND: Aspirin (acetylsalicylic acid) is commonly prescribed to patients with a history of myocardial infarction (MI) or occlusive vascular events (e.g., stroke). Due to the complications associated with failure to follow aspirin usage guidelines, determining predictors of aspirin noncompliance in these patient populations is of clinical value and may help prevent poor outcomes. METHODS: This cross-sectional study of all patients with a previously diagnosed MI was conducted over a period of 3 months from May 2015 to July 2015 at a government-based hospital in Karachi, Pakistan. Patients were administered a questionnaire that comprised two parts. Part A was designed to measure sociodemographic data including age, gender, and marital status. Part B determined whether the patient was counseled on aspirin significance, and dosage recommendation, and was participating in cardiac rehabilitation therapy. RESULTS: A total of 456 patients included in the study. Of them, 298 (66.7%) were males. The average age was 59 (standard deviation 11) years. The outcome from univariate logistic regression revealed that with 1 year increase of age, the usage of low dose of aspirin was significantly decreased by 2%. Patients with higher education attributed a significantly different effect on the usage of aspirin. Marital status divulged no significant association with the use of different doses of aspirin. The role of rehabilitation had no effect when adjusted for age and level of education. CONCLUSION: Post-MI patients with higher education level and undergoing rehabilitative therapy are more likely to take low-dose aspirin as compared to those who failed to have these attributes. There is a need for carrying out further work to confirm these findings and expand our recommendations, particularly the sensitive issue regarding adequate doctor counseling among these high-risk patients.

Shah et al. (2018) conducted a cross-sectional in Myocardial infarction (n=456). Sociodemographic factors and rehabilitation therapy was evaluated on Usage of low dose of aspirin. In post-MI patients, higher education and rehabilitative therapy were associated with increased low-dose aspirin usage, whereas each 1-year increase in age significantly decreased usage by 2%.
