Clinical Trial of Cilostazol Eluting Stent System (CES-1) in De Novo Coronary Artery Lesions

Más betegség

• Acute myocardial infarction Patients whose CK-MB or troponin exceeds the facility reference upper limit and have at least one of the following is confirmed are excluded as acute myocardial infarction.
  • Ischemic symptoms and Electrocardiographic findings showing continuous ischemia (eg, ST segment elevation or depression above 1 mm in contiguous leads, or the appearance of a new left bundle branch block).
  • Pathological Q waves on electrocardiogram
  • Myocardial necrotic focus or wall motion abnormality newly confirmed in diagnostic imaging
• Patients who cannot be administered antiplatelet drugs. The following cases are conceivable.
  • Significant intracranial hemorrhage, gastrointestinal bleeding, urinary tract hemorrhage etc. within the last 6 months
  • Surgical operation is planned that requires discontinuation of DAPT after the procedure
  • Anticoagulation therapy is underway and the risk of bleeding is high
• Bleeding tendency due to hemorrhagic diathesis or blood coagulation disorder.
• Allergy to cobalt chrome alloy or contrast agent.

Laborértékek

• Left ventricular ejection fraction (LVEF) is less than 30% within 30 days before the trial registration.
• Renal dysfunction (Creatinine value exceeds 2.0 mg/dl or in case artificial dialysis).
