Why might dual antiplatelet therapy be recommended?

Dual antiplatelet therapy is recommended primarily to provide enhanced protection against clot formation. This approach involves the use of two different medications that inhibit platelet aggregation, which is crucial in preventing thrombus formation that can lead to serious cardiovascular events, such as myocardial infarction or stroke.

By utilizing two antiplatelet agents, the likelihood of clot development is significantly reduced because they work through different mechanisms to inhibit the activation and aggregation of platelets. For example, one medication might block a receptor on the platelet surface, while the other might inhibit a different pathway involved in the clotting process. This combined effect offers superior antithrombotic protection compared to using a single agent.

In contrast, enhancing cholesterol levels, reducing blood pressure after surgery, or increasing platelet concentrations do not directly address the mechanisms of clot formation and would not warrant the use of dual antiplatelet therapy. These other factors might be considerations in overall patient management but do not play a role in the rationale for dual antiplatelet therapy.
