Brief Summary

Studies showed that combined use of clopidogrel and aspirin had a 25 % reduction of risk on myocardial infarction and stroke in patients who undergone percutaneous coronary intervention (PCI) when compared with use of aspirin alone. However, major GI bleeding rose in combined group than aspirin group. Use of proton pump inhibitor (PPI) which diminishes gastric acid secretion effectively reduces aspirin or clopidogrel associated ulcer or/and ulcer bleeding in general population and high risk patients. The investigator hypothesis is whether use of PPI can reduce ulcer and ulcer complication in patients taking both clopidogrel and aspirin.

Outcome Measures

Primary Outcomes (1)

  • The primary end point is the occurrence of clinical upper GI events (symptomatic ulcer and ulcer complications-bleeding, perforation, or obstruction)

    3 month follow-up

Secondary Outcomes (1)

  • The secondary end point is occurrence of dyspepsia, asymptomatic gastroduodenal ulcers

    3 month follow-up

Study Arms (2)

1

ACTIVE COMPARATOR

Upper GI tract symptoms are evaluated. Patients are asked to report to gastroenterologist if they have persistent ulcer symptoms and to report to the emergency room if they have evidence of GI bleeding or ulcer complications (melena, hematemesis, or sudden onset of severe epigastric pain). Endoscopy will be undergone to document any gastroduodenal ulcers with or without ulcer complications. If the hemoglobin level has decreased by 2g/dL or more, or stool check shows occult blood at each visit, endoscopy will be undergone to check the presence of gastroduodenal ulcers with or without bleeding. Patients without persistent ulcer symptoms or without evidence of ulcer complications will be invited to undergone scheduled endoscopy at the 3-month end of follow-up in each subjective.

Drug: lansoprazole

PLACEBO COMPARATOR

Upper GI tract symptoms are evaluated at each visit. Patients are asked to report to gastroenterologist if they have persistent ulcer symptoms and to report to the emergency room if they have evidence of GI bleeding or ulcer complications (melena, hematemesis, or sudden onset of severe epigastric pain). Endoscopy will be undergone to document any gastroduodenal ulcers with or without ulcer complications. An ulcer is defined as a circumscribed mucosal break at least 3 mm in diameter. If the hemoglobin level has decreased by 2g/dL or more, or stool check shows occult blood at each visit, endoscopy will be undergone to check the presence of gastroduodenal ulcers with or without bleeding. Patients without persistent ulcer symptoms or without evidence of ulcer complications will be invited to undergone scheduled endoscopy at the 3-month end of follow-up in each subjective.

Eligibility Criteria

Age40 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients are eligible if they have received PCI for their stenotic coronary arteries and taken both aspirin and clopidogrel.
  • Patients who had a past history of PUD without complication, who have taken aspirin or clopidogrel before enrolling for their CV disease will be allowed to enroll.

You may not qualify if:

  • Patients are excluded if they have New York Heart Association class IV heart failure, if they had contraindications to antithrombotic or antiplatelet therapy, if they have clinical severe thrombocytopenia (platelet count\< 80000/mm3), if they have previous disabling, or hemorrhagic stroke or intracranial hemorrhage, if they have severe and unstable conditions in hepatic, renal, and pulmonary disease, if they have unstable and progressive malignancy, if they have epigastralgia or have a positive occult blood in stool, if they have current or recent PUD and take PPI or histamine receptor-2 antagonist without proving healed ulcer by scopy, if they have received a surgical intervention due to PUD complication (bleeding, perforation, obstruction) in the past, if they have received a GP IIb/IIIa inhibitor fewer than 3 days before randomization.
