Title: A Multicenter Randomized Trial Evaluating the Efficacy of Sarpogrelate on Ischemic Heart Disease After Drug-eluting Stent Implantation in Patients With Diabetes Mellitus or Renal Impairment
Brief Summary: The purpose of the SERENADE trial is to evaluate the safety and efficacy of sarpogrelate in patients with CKD or DM after DES implantation.


Options:
A: Inclusion Criteria:

* symptomatic CAD (including acute coronary syndrome) or positive stress test and a native coronary lesion (\>50% diameter stenosis by visual estimation on coronary angiogram and reference diameter \> 2.5 mm)
* AND CKD or DM patients

Exclusion Criteria:

* if they had contraindication to aspirin, clopidogrel or sarpogrelate.
B: Inclusion Criteria:

1. Are undergoing noncardiac surgery;
2. Are ≥ 45 years of age;
3. Are expected to require at least an overnight hospital admission after surgery; AND
4. Fulfill one or more of the following 5 criteria:

   * History of coronary artery disease
   * History of peripheral vascular disease
   * History of stroke
   * Undergoing major vascular surgery
   * Any 3 of the following 9 criteria:

     * undergoing major surgery (i.e. intraperitoneal, intrathoracic, retroperitoneal or major orthopedic surgery
     * history of congestive heart failure
     * transient ischemic attack
     * diabetes and currently taking an oral hypoglycemic agent or insulin
     * age ≥ 70 years
     * hypertension
     * serum creatinine \> 175 µmol/L (\> 2.0 mg/dL)

12. Planned use - during the first 3 days after surgery - therapeutic dose anticoagulation or a therapeutic subcutaneous or intravenous antithrombotic agent
13. Undergoing intracranial surgery, carotid endarterectomy, or retinal surgery
14. Not consenting to participate in POISE-2 prior to surgery
15. Previously enrolled in POISE-2 Trial
C: Inclusion Criteria:
