Insights
Dual antiplatelet therapy with aspirin and clopidogrel shows benefits but has variable patient responses. Platelet function tests may help identify high-risk patients and personalize treatment for better outcomes.
Area of Science:
- Cardiology
- Pharmacology
- Clinical Medicine
Background:
- Dual antiplatelet therapy (DAPT) with aspirin and clopidogrel is standard for acute coronary syndromes and percutaneous coronary intervention.
- Significant interindividual variability exists in patient response to DAPT.
- Identifying patients at high risk for recurrent ischemic events is crucial.
Purpose of the Study:
- To review current platelet function tests.
- To discuss the advantages and disadvantages of each test.
- To explore the clinical applicability of these tests in tailoring antiplatelet therapy.
Main Methods:
- Literature review of commonly available platelet function tests.
- Analysis of test performance, including sensitivity and specificity.
- Discussion of clinical utility and limitations.
Main Results:
- Various platelet function tests are available, each with unique strengths and weaknesses.
- These tests can identify patients with suboptimal response to aspirin and clopidogrel.
- Evidence suggests potential for guiding antiplatelet therapy adjustments.
Conclusions:
- Platelet function testing offers a promising approach to personalize DAPT.
- Further research is needed to establish definitive clinical guidelines for test application.
- Optimizing antiplatelet therapy can potentially reduce ischemic events.
Abstract:
Despite the clinical benefit associated with the combined use of aspirin and clopidogrel in patients with acute coronary syndrome or those undergoing percutaneous coronary intervention, a considerable interindividual variability in response to these drugs have been consistently reported. There is a growing interest on applying platelet functional tests with the goal of identifying patients at increased risk of recurrent ischaemic events and potentially tailoring antiplatelet treatment regimens. This manuscript will review the state of the art on the most commonly available platelet functional tests, describing their advantages and disadvantages and exploring their applicability in clinical practice.
