Outcome Measures
Primary Outcomes (1)
To evaluate the rate of recovery of platelet COX-1 activity, measured between 12 and 24 hours after low-dose (100 mg) ASA administration by means of three determinations of serum TXB2 levels, at day 8±1, comparing CASE group vs. CONTROL Group.

day 8±1
Study Arms (2)
CASE
patients experiencing a recurrent stroke while on ASA therapy
CONTROL
ASA-naïve patients experiencing a first atherothrombotic stroke
Interventions
Blood samples are analyzed for the assay of serum TXB2, and urine samples for the assay of 11-dehydro-TXB2
Eligibility Criteria
Hospitalized patients with athero-thrombotic stroke, to be divided into CASE group (50 patients experiencing a recurrent stroke while on ASA therapy) and CONTROL group (50 ASA-naïve patients experiencing a first atherothrombotic stroke), with ratio 1:1.
You may qualify if:
- Age ≥18 years
- Swallow-test positive
- Patients hospitalized for a first event of athero-thrombotic stroke (CONTROL group)
- Patients hospitalized for a recurrence of athero-thrombotic stroke on ASA therapy (CASE group)
- Informed Consent
You may not qualify if:
- Transient ischemic attack (TIA)
- Chronic treatment with non-steroidal anti-inflammatory drugs (if occasional, not within 4 days prior to hospitalization)
- Current treatment with oral or parental anticoagulants at prophylactic or therapeutic doses
- Current treatment with other antiplatelet agents
- Thrombolysis and thrombectomy
- Cardio-embolic stroke CENTRO STUDI FONDAZIONE FADOI Page 10 Studio FADOI.01.2018 Versione n. 2 del 26/09/2019
- Carotid stenosis \>70%, with indication for revascularization
- Current treatment with ASA (only for patients in the CONTROL group)
- Acute hepatitis, chronic active hepatitis, liver cirrhosis - or alanine aminotransferase level 3 times or more and/or bilirubin level 2 times or more higher than the upper limit of the normal range
- Thrombocytopenia (\<150000 platelets/μl)
- Renal failure (eGFR \<30 ml/min)
- Active cancer or disease in complete remission \<1 year, except squamous cell carcinoma and basal-cell carcinoma of the skin at initial stage
- Severe chronic obstructive pulmonary disease (COPD) (oxygen therapy)
- Uncontrolled hypertension (systolic BP \>180 mmHg or diastolic BP \>100 mmHg despite antihypertensive treatment)
- Chronic inflammatory bowel disease
