Влияние аторвастатина и розувастатина на остаточную реактивность тромбоцитов при приеме клопидогреля у больных ишемической болезнью сердца и сахарным диабетом 2 типа после перенесенного острого коронарного синдрома

Abstract

In patients with ischemic heart disease and type 2 diabetes mellitus in 4-6 weeks after acute coronary syndrome (ACS) on stable dual antiplatelet therapy (DAPT) with aspirin and clopidogrel co-adminstrated with rosuvastatin residual platelet reactivity on adenosine diphosphate was higher than in patients receiving atorvastatin. However, the rate of high residual on-clopidogrel treatment platelet reactivity (RCPR) in rosuvastatin-treated patients exceeded the rate of high RCPR in atorvastatin-treated patients insignificantly. In 6 months after ACS residual platelet reactivity did not differ between the groups. After 12 months of DAPT platelet reactivity increased as compared to baseline values both in patients receiving rosuvastatin and in patients receiving atorvastatin without switching. In patients, randomly switching from one statin type to another at 6 month of treatment, platelet reactivity did not change significantly in comparison to baseline and the prevalence of high RCPR was lower than in patients receiving statins without switching. Thus, in patients with diabetes with ACS on DAPT with acetylsalicylic acid and clopidogrel statin treatment should be started with atorvastatin and in 6 months after ACS atorvastatin should be switched to rosuvastatin. This approach will provide lower RCPR within at least first 4-6 weeks after ACS and prevent RCPR increase during 12 months of DATT use in this patients group.
