BACKGROUND: Patients with peripheral artery disease have an increased risk of cardiovascular morbidity and mortality. Antiplatelet agents are widely used to reduce these complications. METHODS: This was a multicentre, double-blind, randomised placebo-controlled trial for which patients were recruited at 602 hospitals, clinics, or community practices from 33 countries across six continents. Eligible patients had a history of peripheral artery disease of the lower extremities (previous peripheral bypass surgery or angioplasty, limb or foot amputation, intermittent claudication with objective evidence of peripheral artery disease), of the carotid arteries (previous carotid artery revascularisation or asymptomatic carotid artery stenosis of at least 50%), or coronary artery disease with an ankle-brachial index of less than 0·90...

Antiplatelet therapy is the cornerstone of the therapeutic arsenal in coronary artery disease. Thanks to a better understanding in physiology, pharmacology and pharmacogenomics huge progress were made in the field of platelet reactivity inhibition thus allowing the expansion of percutaneous coronary intervention. Stent implantation requires the combination of two antiplatelet agents acting in a synergistic way. Asprin inhibit the cyclo-oxygenase pathway of platelet activation while clopidogrel is a P2Y12 adenosine diphosphate (ADP)-receptor antagonist...

Hemodialysis ("HD") has been suggested as a risk factor for stent thrombosis. However, platelet function in HD patients after coronary stent implantation remains unclear. The aim of this study was to evaluate platelet function following coronary stent implantation in HD patients. A total of 10 HD and 31 non-HD patients who underwent a first coronary stent implantation were studied. All patients received 100 or 200 mg of asprin and thienopiridine (either ticlopidine 200 mg or clopidogel 75 mg) daily. Platelet function was assessed 2-6 weeks (21 ± 8 days) after stent implantation by: (1) platelet maximal aggregation, using light transmittance aggregometry; (2) platelet aggregation threshold index, which was defined as putative concentration of agonist giving 50% maximum aggregation using whole-blood aggregometry; and (3) platelet activation markers (PAC-1 and CD62p), using whole blood flow cytometry...

Laparoscopic cholecystectomy has become the standard of care for patients with acute cholecystitis, symptomatic cholelithiasis, and biliary dyskinesia. Most surgeons now perform this procedure as outpatient surgery. In a standard laparoscopic cholecystectomy procedure, three trocar incisions are made outside the umbilicus. Stopping the bleeding from these port sites can be problematic because of the small size of the incision and the fact that these bleeding points are situated deep in the incision. This is especially true in obese patients and patients taking Asprin or Plavix and undergoing emergency cholecystectomy...

Over a 10-year period, between 1986 and 1996, 865 patients underwent primary aortic valve replacement (AVR) with the St. Jude Medical mechanical prosthesis. Patients who had undergone valve replacement with a different type of prosthesis previously were excluded from this study. Patient age ranged from 11 to 79 years. The mean age was 42.9 +/- 14.54. The gender distribution was 396 men (45.8%) and 469 women (54.2%). All patients received 2.5 mg/day Coumadin after extubation. A combination of the antiaggregant therapy (Dypridamole 3X 75 mg/day, Asprine 100 mg/day) was added after removal of the chest tubes...

Among 2,656 patients receiving heparin sodium therapy, bleeding was a dose-related phenomenon that occurred most commonly among women, severely ill patients, and patients who received asprin during heparin therapy. Except for dose, factors that predisposed patients to bleeding were more strongly associated with major bleeding than with minor bleeding. Heavy alcohol drinkers were at particularly high risk for major bleeding episodes during heparinization. The seven-day cumulative risk for any bleeding was 9...
