Adherence to statins among STEMI survivors who received low or no-cost medication was evaluated over a 10-year period in a cohort study conducted in Quebec, Canada.
Despite initial concerns regarding medication costs, the study found that optimal adherence (defined as taking statins at least 80% of the time) remained stable at around 80% over the decade, though 12% of patients stopped using lipid-lowering therapy in the last five years.
Factors that improved adherence included older age, living in less deprived areas, and the use of other heart medications; further research is needed to understand these influences and support socially deprived patients in maintaining their statin regimen.
