Clinical features and pharmacological treatment of patients with ASA-sensitive and ASA-resistant platelets.

ACE: angiotensin-converting enzyme. CT: closure time after one hour of the last ASA administration. CT is the time necessary for the occlusion of the open pore in the PFA-100 cartridges and it is indicative of platelet function. The upper limit of the PFA-100 test is 300 seconds. The results of categorical variables are represented as number of cases with respect to the total included patients within each experimental group. Age is represented as mean ± SEM. *p<0.05 with respect to patients with ASA-sensitive platelets.
