Filter by:The purpose of this study is to compare the efficacy and safety for 12- vs. 1-month of pantoprazole treatment in preventing dual antiplatelet therapy (DAPT)-related upper gastrointestinal mucosal injury after coronary artery bypass grafting (CABG). To date, there has been no study using esophagogastroduodenoscopy (EGD) to compare the differences in upper gastrointestinal mucosal injury (including reflux esophagitis) after 6 and 12 months of PPI treatment combined with two different DAPT regimens (clopidogrel plus aspirin or ticagrelor plus aspirin).
Coronary Artery Disease (CAD) is leading cause of death worldwide. Most of them underwent coronary angiography and they have to use dual anti-platelet therapy. As mentioned novel guidelines for CAD, the estimated number of patients requiring dual anti-platelet therapy has increased over time, and DAPT time is controversial. Acting on the behalf of 2017 ESC focused update on dual anti-platelet therapy in coronary artery disease developed in collaboration with EACTS guideline, this study is amid to determine PRECISE-DAPT score which predicts out of hospital bleeding risk in patients receiving dual anti-platelet treatment and to detect the prevalence of patients with high bleeding risk, and to determine DAPT score which predicts benefit/risk ratio of continuing or discontinuing dual ant-iplatelet therapy after 12 months and to detect the prevalence of patients with high ischemic or hemorrhagic complication risk in centers included in this study.
The objective of this study is to determine if the administration of platelets will improve outcome in patients with ICH who are being treated with either aspirin, a thienopyridine (ticlodipine, clopidogrel, prasugrel) or a combination of both. The study has four specific aims: 1. To determine what affect platelet administration will have on bleeding in the brain. 2. To determine what affect platelet administration will have on brain function. Several assessments to test the functioning of the brain will be performed at enrollment and throughout the study. Comparing the results of these assessments between the experimental and control groups should allow us to determine if platelet administration improves outcomes in patients with bleeding in the brain exposed to antiplatelet therapy. 3. An important risk of reversing antiplatelet therapy is exposing the patient to the very complications this therapy was designed to prevent. Therefore, tracking complications will be a very important part of this study. The investigators will compare the rates of death, heart attack, stroke and clots in the veins between groups. 4. Some patients (10-40%) have limited responsiveness to antiplatelet therapy. While platelet responsiveness, as measured by a special platelet blood test, will not affect enrollment, the investigators feel it will be important to measure.
At our VA hospital, in general, it is the policy of our GI lab to not stop our patients anti-platelet therapy whenever they see us for a routine colonoscopy. We do this because we believe the risk of stopping these sort of medications outweigh the risks of a complication from a colonoscopy. Therefore, we are enrolling patients who are either on clopidogrel or prasugrel or not on any anti-platelet/anti-coagulant therapy that come to our GI lab routine colonoscopies. We perform the procedure just like we normally would and then follow-up with the patient 7 and 30 days after their procedure.
