Antiplatelet Therapy and Endothelial-stabilizing Agents in Cerebral Small Vessel Diseases

Korábbi kezelés

• Major surgery (including open femoral, aortic, cardiac or carotid surgery) within previous 30 days or planned in the 1 year after enrollment.

Más betegség

• Intracranial aneurysms that need surgical treatment. Other significant active neurological illness e.g seizures, multiple sclerosis, intracranial tumor (except meningioma) or any intracranial vascular malformation.
• Active cardiac disease (atrial fibrillation, myocardial infarct in last six months, active angina, symptomatic cardiac failure).
• History of any intracranial hemorrhage (parenchymal, subarachnoid, subdural, epidural).
• Known allergy or contraindication to aspirin, clopidogrel, cilostazol, isosorbide mononitrate or statin.
• Dementia or psychiatric problem that prevents the patient from relevant evaluation or follow-up reliably.
• Co-morbid conditions that may limit survival to less than 1 year.

Laborértékek

• Active peptic ulcer disease, major systemic hemorrhage within 30 days, active bleeding diathesis, platelets < 100,000, hematocrit < 30, international normalized ratio (INR) > 1.5, clotting factor abnormality that increases the risk of bleeding, current alcohol or substance abuse, uncontrolled severe hypertension (systolic pressure > 180 mm Hg or diastolic pressure > 115 mm Hg), severe liver impairment (aspartate transaminase [AST] or alanine transaminase [ALT] > 3 x normal, cirrhosis), creatine kinase > 5 times the upper limit of normal (ULN) at final screening, severe renal dysfunction, defined as an estimated glomerular filtration rate (eGFR) < 20mL/min/1.73 square meter at final screening.
