thienopyridine and Death--Sudden--Cardiac

In a series of articles the authors consider clinical pharmacology and experience of clinical application of blockers of platelet P2Y12 receptors, most well known representatives of which ticlopidine and clopidogrel according to chemical structure belong to thienopyridine derivatives. In the fifth communication we consider data of two randomized studies in which efficacy and safety of clopidogrel in combination with acetylsalicylic acid (ASA) has been assessed in comparison with ASA in stable patients with atherothrombotic cardiovascular disease. It has been shown in both studies that in stable patients with atherothrombotic cardiovascular disease long-term therapy with combination of clopidogrel and ASA was no more effective than monotherapy with ASA or clopidogrel but was associated with high risk of hemorrhagic complications. Thus contrary to acute coronary syndromes and percutaneous interventions with stenting combinations of clopidogrel and ASA is not indicated to patients with stable course cardiovascular diseases.
