ReviewHarms and Benefits of Using Aspirin for Primary Prevention of Cardiovascular Disease: A Narrative Overview.
Aspirin is one of the most often used drugs for prevention and treatment of a variety of thrombotic disorders. This narrative review aims to provide an overview of evidence highlighting potential benefits and relative harms of aspirin in primary prevention of cardiovascular disease. The authors summarize key findings of the ASPirin in Reducing Events in the Elderly (ASPREE) Investigator Group randomized trial and also provide a comparative overview of recent meta-analyses. ⋯ Furthermore, one meta-analysis reported a lower risk of future cancer, others failed to report a significant effect, and the ASPREE Investigator Group trial reported a 31% increased risk. Unlike these conflicting outcomes, the bleeding risk of patients receiving aspirin was found to be consistently enhanced in all reports reviewed. These recent findings would lead us to conclude that the harms of aspirin in primary prevention of cardiovascular disease may be larger than the benefits, especially in the elderly general population.
