Aspirin is one of the most widely taken medicines in the world, having been recommended for decades as a way of protecting against heart attacks and strokes in at-risk patients. However, a new study has revealed that clopidogrel, another commonly used blood thinner, or anticoagulant, is more effective in preventing serious heart attacks and strokes and carries no additional risk. In total, this meta-analysis looked at clinical data from nearly 29,000 patients diagnosed with coronary artery disease (CAD), a condition where fat builds up in the arteries, which can lead to secondary effects such as heart attacks and heart failure. The aim was to identify papers comparing the efficacy of aspirin versus clopidogrel in the prevention of cardiovascular deaths, heart attacks, and strokes. Ultimately, the team concluded that these findings “add to the evidence” that clopidogrel is superior to aspirin for preventing major adverse cardiac and cerebrovascular events.
