Drug Information available for: Cilostazol

Intervention Details:
  • Drug: Cilostazol, Probucol / placebo of probucol
    An investigator-initiated, placebo-controlled, randomized, multi-center study. Enrolled patients will be randomized after PCI either to the combination therapy group or to the control group. In the combination therapy group, cilostazol 200 mg and probucol 500 mg will be administered daily, whereas the control group will receive cilostazol 200 mg daily only.

Primary Outcome Measures :
  1. Plaque volume change of the index lesion with intermediate stenosis(non-PCI target lesion) [ Time Frame: From February 01, 2009 to July 31, 2011 ]

Ages Eligible for Study:   20 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patients treated with PCI with stent
  2. Male or female over 20 years of age
  3. Presence of at least one PCI target lesion(lesion length ≤26mm) with ≥50% diameter stenosis that can be covered with a single Endeavor Sprint stent(Medtronic)
  4. Other PCI target lesions also should be treated with Endeavor Sprint stents
  5. Presence of an intermediate non-PCI target lesion with luminal narrowing of ≥30% and ≤70% by visual estimation
  6. Signed written informed consent to participate in the study

Exclusion Criteria:

  1. Intermediate (non-PCI target) lesions that might provide difficulty for IVUS evaluation because of following reasons: heavy calcification (>90° Arc), tortuous vessel with sever angulation, total occlusion, or bifurcation lesions
  2. Previous PCI in the last 6 months
  3. Previous CABG
  4. Patients with AMI undergoing primary PCI or rescue PCI after thrombolysis
  5. Cardiogenic shock
  6. Inability to take adequate anti-platelet therapy
  7. Thrombocytopenia (platelet count <70 x 109/l)
  8. Known hypersensitivity or contraindication to any of the following medications: Heparin, aspirin, clopidogrel, cilostazol, probucol, statin, contrast media*

    *Patients with documented sensitivity to contrast media which can be effectively pre-medicated with steroids and diphenhydramine [e.g. rash] may be enrolled. Those with true anaphylaxis to prior contrast media, however, should not be enrolled.

  9. History of severe ventricular arrhythmia
  10. Significant QTc prolongation (≥470 ms) on ECG
  11. NYHA class III/IV heart failure or LV ejection fraction ≤35%
  12. Familial hypercholesterolemia
  13. Uncontrolled hypertriglyceridemia (>400 mg/dL)
  14. Chronic renal failure with serum creatinine level ≥2mg/dL
  15. Severe liver disease or transaminase level ≥3 times the upper limit of normal.
  16. Pregnant or breastfeeding
