La valutazione e l’applicazione di strategie antitrombotiche in grado di ridurre la mortalità totale e cardiovascolare in pazienti con malattia vascolare già documentata hanno un ruolo importante di tipo clinico, epidemiologico e di economia sanitaria. Nello studio COMPASS l’associazione di rivaroxaban, somministrato alla dose di 2.5 mg ogni 12 h, ed aspirina in una popolazione con malattia vascolare stabile ha significativamente ridotto gli eventi cardiovascolari rispetto al regime standard con sola aspirina; tale riduzione si è tradotta in un’aumentata sopravvivenza, sia cardiovascolare che totale. Questo beneficio di mortalità non era stato osservato negli studi randomizzati che, in questa tipologia di pazienti, avevano in precedenza valutato terapie antipiastriniche alternative all’aspirina (con il clopidogrel) oppure avevano confrontato una doppia terapia antiaggregante con aspirina più clopidogrel, vorapaxar o ticagrelor vs singolo trattamento antiaggregante con aspirina. I risultati del COMPASS rinforzano l’importanza di strategie antitrombotiche che coinvolgano anche la cascata coagulativa, oltre che l’aggregazione piastrinica, per prevenire a livello multi-distrettuale la ricorrenza di eventi cardiovascolari su base aterotrombotica, con un beneficio proporzionale al profilo di rischio basale del paziente.

Abstract
The evaluation and application of antithrombotic strategies able to reduce total and cardiovascular mortality in patients with documented vascular disease have an important clinical and epidemiological role and may also impact on health costs. In the COMPASS trial, the association of rivaroxaban at the dose of 2.5 mg twice daily with aspirin in a population with stable vascular disease has significantly reduced the incidence of cardiovascular events compared to the standard regimen of aspirin alone; this reduction translated into greater cardiovascular and total survival. Such mortality benefit was not observed in previous randomized trials that in this setting of patients had previously evaluated antiplatelet strategies alternative to aspirin (with clopidogrel) or had compared a dual antiplatelet therapy with aspirin plus clopidogrel, vorapaxar, or ticagrelor vs a single antiplatelet treatment with aspirin. The results of the COMPASS trial strengthen the role of antithrombotic strategies that, beside the platelet phase, also involve the coagulative phase with the aim at preventing the recurrence of cardiovascular, atherothrombotic events at the site of polyvascular beds, with a degree of benefit proportional to the baseline risk of the patient.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
