Filter by:In this non-interventional one year study, data about overall and particularly gastrointestinal tolerability, indications, cardiovascular risk factors and compliance are collected by basic questionnaires, which are handed out by pharmacists to patients who acquire (in Germany no prescription is needed) Rx (Prescription) or OTC (Over-The-counter) Aspirin protect (enteric coated aspirin) 100 mg and are willing to participate in the study. After 3, 6, 9 and 12 months follow-up questionnaires are sent out. Aim of the study is to get information about safety, usage and compliance under everyday's conditions, because in Germany low-dose aspirin is an OTC product with Rx indication.
The purpose of this study is to assess the the 1-year rates of ischemic and bleeding complications in patients whose dual antiplatelet therapy regimen post-PCI has been determined with the use of a clinical algorithm that includes both clinical risks and platelet reactivity while on chronic clopidogrel therapy.
Antiplatelet therapy is critical in the management of coronary artery disease.For patients undergoing off-pump coronary artery bypass graft,controversy remains regarding the safety of preoperative antiplatelet therapy.And there is little study about the effect of continuing aspirin until the surgery day on graft patency.So we would like to perform this study to evaluate the effects of preoperative aspirin on graft patency and cardiac events in off-pump coronary bypass.
Lung cancer is the most common cancer in the western world. Only 10 to 15 % of patients diagnosed with lung cancer are suitable for potentially curative surgical treatment. Despite surgery, recurrence of lung cancer still occurs. Aspirin potentially may help increase survival by altering the biochemistry of any potential remaining lung cancer cells. Most lung cancer occurs in smokers. Smokers are at increased risk of heart attacks and strokes. Aspirin has beneficial effects on the heart and brain, potentially reducing the incidence of heart attacks and strokes.
Aspirin can prevent ischemic vascular disease but is commonly complicated by dyspepsia in 30% of patients. Patients, who have aspirin related dyspepsia, commonly underwent upper endoscopy to exclude peptic ulcer disease or gastric cancers. For those without significant lesions in the stomach and duodenum (non-ulcer dyspepsia), the best approach in the management is unclear. The objective of this study is to compare the efficacy of esomeprazole and famotidine in the control of dyspeptic symptom. After giving consent, patients will be randomised to receive either esomeprazole 20 mg daily or famotidine 40 mg daily in a double blinded manner. The patient will be followed-up at the 2nd and 4th week. The study will be completed at the 4th week. The primary analysis will be the efficacy in the control of dyspepsia symptom between the two groups.
The purpose of this study is to determine the effect of clopidogrel or aspirin reactivity as measured by a point-of-care platelet function assay on thrombotic or bleeding events after percutaneous coronary intervention (PCI) with drug eluting or bare metal stent. Methods: Platelet reactivity on clopidogrel and aspirin therapy is measured before PCI with VerifyNow (Accumetrics Inc.,San Diego, CA, USA) P2Y12 or aspirin assay respectively in 1000 consecutive patients from 20 centers in France undergoing coronary angioplasty with stent. Exclusion criteria are: Acute myocardial infarction, treatment with vitamin K antagonists and the use of antiGP2b3a before PCI. All patients are pre-treated with clopidogrel and aspirin. Non-response to aspirin or clopidogrel is determined according to the result of the VerifyNow assay (cut off : < 15 % for P2Y12 and > 550 ARU for aspirin). The primary end point is the occurrence of definite or probable stent thrombosis (ARC definition) and the secondary end-points include global and cardio-vascular mortality, non fatal myocardial infarction and major bleeding. A clinical evaluation is scheduled at discharge and by telephone contact at one month and one year.
Pilot study of continuing aspirin versus switching to clopidogrel after stroke or transient ischemic attack.
