Применение PPI можно расценивать, как я думаю, как частный случай такой резистентности.

я думаю, да

Еще один возможный путь преодоления резистентности?

Objectives: The purpose of this study was to determine the impact of adjunctive cilostazol in patients with high post-treatment platelet reactivity (HPPR) undergoing coronary stenting.

Background: Although addition of cilostazol to dual antiplatelet therapy enhances adenosine diphosphate (ADP)-induced platelet inhibition, it is unknown whether adjunctive cilostazol can reduce HPPR.

Methods: Sixty patients with HPPR after a 300-mg loading dose of clopidogrel were enrolled. HPPR was defined as maximal platelet aggregation (Aggmax) >50% with 5 µmol/l ADP. Patients were randomly assigned to receive either adjunctive cilostazol (triple group; n = 30) or high maintenance dose (MD) clopidogrel (high-MD group; n = 30). Platelet function was assessed at baseline and after 30 days with conventional aggregometry and the VerifyNow assay.

Results: Baseline platelet function measurements were similar in both groups. After 30 days, significantly fewer patients in the triple versus high-MD group had HPPR (3.3% vs. 26.7%, p = 0.012). Percent inhibitions of 5 µmol/l ADP-induced Aggmax and late platelet aggregation (Agglate) were significantly greater in the triple versus high-MD group (51.1 ± 22.5% vs. 28.0 ± 18.5%, p < 0.001, and 70.9 ± 27.3% vs. 45.3 ± 23.4%, p < 0.001, respectively). Percent inhibitions of 20 µmol/l ADP-induced Aggmax and Agglate were consistently greater in the triple versus high-MD group. Percent change of P2Y12 reaction units demonstrated a higher antiplatelet effect in the triple versus high-MD group (39.6 ± 24.1% vs. 23.1 ± 29.9%, p = 0.022).

Conclusions: Adjunctive cilostazol reduces the rate of HPPR and intensifies platelet inhibition as compared with a high-MD clopidogrel of 150 mg/day.
