E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Will be enrolled in the study patients suffering from intermittent claudication in whom resulted ineffective both pharmacological and workout therapy- Will be considered eligible patients aged 40-80 inclusive, with an ankle-brachial index (ABI) <0.9 or > 1.3 at basal condition and diametrical arterial stenosis equal or superior to 50% vessel lumen, undergoing peripheral revascularization procedures. |
Pazienti affetti da claudicatio intermittens nei quali non sono efficaci né il trattamento farmacologico né la terapia basata sull’esercizio fisico. Saranno eleggibili se di età compresa tra i 40 e gli 80 anni, con un indice caviglia-braccio [ankle-brachial index (ABI)] < 0.9 o > 1.3 in condizioni di base e stenosi diametriche delle arterie pari o superiori al 50% del lume vasale, sottoposti a procedure di rivascolarizzazione periferica. |

E.1.1.1 | Medical condition in easily understood language |
Will be enrolled in the study patients reporting a reduced walking autonomy, because an arterial lower extremity circulation impairment. |
Saranno arruolati nello studio pazienti con ridotta autonomia di marcia a causa di alterazione della circolazione arteriosa degli arti inferiori. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate antiplatelet treatment resistance percentage, considering the residual platelet activity as superior to 70% using ADP or Arachidonic Acid in vitro aggregation tests. |
Valutare la percentuale di resistenza al trattamento antiaggregante piastrinico considerando come Attività piastrinica residua quella superiore al 70% usando o l’ADP o l’Acido Arachidonico (AA) come stimolo nei test di aggregazione piastrinica in vitro. |
|
E.2.2 | Secondary objectives of the trial |
To compare different platelet function test about sensitivity, specificity and future clinical events predictive values; To evaluate the relationship between oxidative stress indexes and platelet activation; To evaluate the antiplatelet treatment resistance role on future clinical events; To evaluate the platelet fuction test predictive role, seric thromboxane levels and oxidative stress indexes levels on future clinical events; To validate a both clinical and laboratory predicitive score to identify the recurrent thrombosis high risk patients; To verify the platelet function tests diffusion in the real world. |
Comparare i test di funzionalità piastrinica in termini di sensibilità,specificità,accuratezza e valori predittivi dei test sugli eventi clinici futuri; Valutare la relazione tra alcuni indici di stress ossidativo e l’attivazione piastrinica; Valutare il ruolo della resistenza al trattamento antiaggregante piastrinico sugli eventi clinici futuri; Valutare il ruolo predittivo dei differenti test di funzionalità piastrinica,del dosaggio del trombossano sierico e degli indici di stress ossidativo sugli eventi clinici futuri; Validare uno score basato su parametri clinici e di laboratorio,che permetta al clinico di identificare i pazienti ad altro rischio di trombosi ricorrente; Verificare la diffusione dei test di funzionalità piastrinica nel mondo reale. |
