Acetylsalicylic acid (Aspirin, ASA) is the most widely prescribed drug used in primary and secondary prevention of cardiovascular disease. However, aspirin resistance has been described, mostly in cardiac patients and is an independent predictive factor for a poor survival. Two frequent conditions in patients with cardiovascular diseases, diabetes and hypercholesterolemia, are also considered as risk factors for aspirin resistance. Among patients with peripheral arterial disease, those with critical limb ischemia have the worst cardiovascular prognosis. At one year, 23% are dead, 25% have a major cardiovascular event and 25% have a major amputation (which can be combined). Aspirin resistance is poorly studied in these patients, and to our knowledge no study has been made to assess the prognosis value of aspirin resistance on cardiovascular outcomes in critical limb ischaemia patients.
Hospitalized critical limb ischaemia patients will be tested for aspirin resistance using the bed-side point of care VerifyNow®, and will be followed during one year, including death, fatal and non-fatal acute coronary syndromes, cardiac decompensation, stroke, and major amputation.

Aspirin resistance is the persistent platelet activation, demonstrated by platelet function tests (1). The hypothesis is that:LDL lowering by statin in patients with aspirin resistance ca...
The purpose of this study is to evaluate possible mechanisms of aspirin resistance at a molecular level in aspirin-treated patients with coronary artery disease. We hypothesize that certa...
Despite treatment with aspirin a large number of patients suffer a myocardial infarction. It has been speculated that these patients might be "resistant" to aspirin, and studies have indic...
The objective of this pilot study is to evaluate the prevalence of biological aspirin resistance in women at risk for CHD taking low dose (81 mg) aspirin. Aspirin responsiveness will be m...
Aspirin is an essential drug for the treatment of cardiovascular disease. The standard dose is 75mg per day (much lower than that for inflammation or fever). One of the side-effects of a...
Aspirin therapy is the clinical gold standard for the prevention of cardiovascular events. However, cardiovascular events still develop in some patients undergoing aspirin therapy. Many laboratory met...
Ramadan fasting (RF) may affect aspirin resistance. We conducted this study in patients with cardiovascular risk (CVR) factors to assess the effect of RF on aspirin resistance and explore whether type...
To investigate the prevalent of aspirin resistance (AR) in stroke and its association with recurrent stroke in 214 patients with ischemic stroke who were receiving aspirin before the stroke onset.
Aspirin resistance (AR) has been reported to present after coronary artery bypass graft causing saphenous vein graft failure. We aimed to investigate the factors that affect the anti-platelet effect o...
Aspirin is a prototypic cyclooxygenase inhibitor with a variety of beneficial effects on human health. It prevents age-related diseases and delays the aging process. Previous research has shown that a...
A non-steroidal anti-inflammatory agent that is less effective than equal doses of ASPIRIN in relieving pain and reducing fever. However, individuals who are hypersensitive to ASPIRIN may tolerate sodium salicylate. In general, this salicylate produces the same adverse reactions as ASPIRIN, but there is less occult gastrointestinal bleeding. (From AMA Drug Evaluations Annual, 1992, p120)
Asthmatic adverse reaction (e.g., BRONCHOCONSTRICTION) to conventional NSAIDS including aspirin use.
A drug combination of aspirin and dipyridamole that functions as a PLATELET AGGREGATION INHIBITOR, used to prevent THROMBOSIS and STROKE in TRANSIENT ISCHEMIC ATTACK patients.
The prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis. (From Martindale, The Extra Pharmacopoeia, 30th ed, p5)
A type of strength-building exercise program that requires the body muscle to exert a force against some form of resistance, such as weight, stretch bands, water, or immovable objects. Resistance exercise is a combination of static and dynamic contractions involving shortening and lengthening of skeletal muscles.
