Résumé
Dual antiplatelet therapy (DAPT) and Renin-angiotensin system inhibitors (RASi) represent the cornerstone in the treatment of patients undergoing percutaneous coronary interventions (PCI), mainly after an acute ischemic event. However, high-on treatment residual platelet reactivity (HRPR), is not infrequent despite optimal medical treatment. Homocysteine (Hcy) is a metabolite of methionine catabolism linked to atherothrombosis. Recently, a potential crosstalk between RAS and Hcy has been suggested, potentially favouring platelet aggregation and cardiovascular disease.Therefore, we aimed to investigate the impact of RASi on Hcy levels and platelet aggregation in patients on DAPT after PCI. Patients undergoing PCI on DAPT with ASA plus an ADP-antagonist (clopidogrel, ticagrelor or prasugrel), were included. RASi comprised angiotensin converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB). Aggregation tests were performed by Multiple Electrode Aggregometry. We included 1210 patients, of whom 862 (71.2%) were on treatment with RASi. Overall, DAPT composition was ASA+clopidogrel in 566 (46.8%) patients, ASA+ticagrelor in 428 (35.4%) and ASA+prasugrel in 216 (17.9%). Median values of Hcy were higher in RASi patients (p = 0.006), who displayed a higher percentage of Hcy above the median value (52.4% vs. 44.8%, p = 0.019, adjustedOR [95%CI] = 1.40 [1.04-1.88], p = 0.027). No differences in HRPR rate were found according to RASi use for ASPI test (3.6% vs. 3.3%, p = 0.88) and ADP test (25.6% vs. 24.3%,p = 0.62; adjustedOR [95%CI] = 1.23 [0.89-1.70], p = 0.220) and according to ADP-antagonist type. A direct linear relationship was observed between platelet reactivity and Hcy in both patients receiving RASi and untreated ones, with higher values of platelet aggregation being observed in patients with Hcy above the median, independently from RASi administration and DAPT strategy. In patients on DAPT after PCI, RASi treatment did not emerge as an independent predictor of HRPR. However, the levels of Hcy were significantly elevated in patients on RASi and related to higher values of platelet reactivity, independently from the DAPT strategy.

BACKGROUND AND AIMS
Dual antiplatelet therapy (DAPT) and Renin-angiotensin system inhibitors (RASi) represent the cornerstone in the treatment of patients undergoing percutaneous coronary interventions (PCI), mainly after an acute ischemic event. However, high-on treatment residual platelet reactivity (HRPR), is not infrequent despite optimal medical treatment. Homocysteine (Hcy) is a metabolite of methionine catabolism linked to atherothrombosis. Recently, a potential crosstalk between RAS and Hcy has been suggested, potentially favouring platelet aggregation and cardiovascular disease.Therefore, we aimed to investigate the impact of RASi on Hcy levels and platelet aggregation in patients on DAPT after PCI.
METHODS AND RESULTS
Patients undergoing PCI on DAPT with ASA plus an ADP-antagonist (clopidogrel, ticagrelor or prasugrel), were included. RASi comprised angiotensin converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB). Aggregation tests were performed by Multiple Electrode Aggregometry. We included 1210 patients, of whom 862 (71.2%) were on treatment with RASi. Overall, DAPT composition was ASA+clopidogrel in 566 (46.8%) patients, ASA+ticagrelor in 428 (35.4%) and ASA+prasugrel in 216 (17.9%). Median values of Hcy were higher in RASi patients (p = 0.006), who displayed a higher percentage of Hcy above the median value (52.4% vs. 44.8%, p = 0.019, adjustedOR [95%CI] = 1.40 [1.04-1.88], p = 0.027). No differences in HRPR rate were found according to RASi use for ASPI test (3.6% vs. 3.3%, p = 0.88) and ADP test (25.6% vs. 24.3%,p = 0.62; adjustedOR [95%CI] = 1.23 [0.89-1.70], p = 0.220) and according to ADP-antagonist type. A direct linear relationship was observed between platelet reactivity and Hcy in both patients receiving RASi and untreated ones, with higher values of platelet aggregation being observed in patients with Hcy above the median, independently from RASi administration and DAPT strategy.
CONCLUSION
In patients on DAPT after PCI, RASi treatment did not emerge as an independent predictor of HRPR. However, the levels of Hcy were significantly elevated in patients on RASi and related to higher values of platelet reactivity, independently from the DAPT strategy.
