Coronary Occlusion/Thrombosis clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT01447498 Completed - Clinical trials for Peptic Ulcer Hemorrhage

Systematic Screening for Risk-factors for Ulcer Bleeding Before Anti-thrombotic Treatment

Start date: April 2011
Phase: N/A
Study type: Interventional

In a prospective randomised study design to investigate, if a systematic risk factor screening for bleeding ulcer in patients, who following percutaneous coronary intervention (PCI) commence a one year combination treatment with low dose aspirin and clopidogrel, followed by prophylactic treatment with a proton pump inhibitor (PPI) in case of increased risk, can reduce the risk of bleeding ulcer. Based on the recently raised suspicion that PPI's, possibly except pantoprazole, reduce the effect of ADP-receptor inhibitors, pantoprazole has been chosen as prophylaxis in the screening group, and analyses will be done to ascertain whether PPI treatment increases the risk of coronary events. Further analyses will be made to see whether PPI prophylaxis in high risk patients can increase compliance with the antithrombotic treatment through a reduction of side effects, thereby reducing the risk of myocardial infarction in particular stent thrombosis. The study population will be analyzed further to identify the patients, who will benefit the most from PPI prophylaxis Hypothesis: screening heart patients for risk factors for bleeding ulcer and subsequently treating high risk patients with PPI can reduce the incidence of bleeding ulcer and increase compliance with the antithrombotic treatment; thereby possibly reducing the risk of coronary events and improving survival. Initial a description of the prevalence of risk factors will be done.
