This study will be a comparative effectiveness research to determine the difference in major adverse cardiovascular events between the group with aspirin after awakening and placebo before bedtime and the group with placebo after awakening and aspirin before bedtime.
Aspirin is the cornerstone of preventive cardiovascular disease (CVD) treatment and bedtime intake of aspirin (chronotherapy) has been shown to reduce morning activity of platelets. It has been shown that platelet reactivity follows a clear circadian rhythm, with a peak of platelet reactivity during the morning (6-12 AM). Importantly, studies have shown in meta-analyses that high platelet activity is predictive of adverse cardiovascular outcomes in patients with stable CVD. Given this knowledge, it is highly likely that the morning peak of platelet reactivity contributes to the morning peak of cardiovascular events and that reduction of morning platelet activity prevents cardiovascular events during morning hours. This may be achieved by intake of aspirin at bedtime instead of on awakening. This study will be a comparative effectiveness research to determine the difference in major adverse cardiovascular events between the group with aspirin after awakening and placebo before bedtime and the group with placebo after awakening and aspirin before bedtime.

To determine the bioequivalence of new formula of aspirin relative to the established commercial effervescent aspirin when taken orally by healthy adult subjects
To demonstrate the acceptability and feasibility of recruitment to a randomised chemoprevention study of standard (300mg) or low dose (100mg) aspirin vs. placebo and/or Vitamin D3 vs. plac...
To determine the bioequivalence of new formula of aspirin relative to the established commercial aspirin plain tablet and aspirin dry granules when taken orally by healthy adult subjects
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 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...
Stroke is a common condition after a transient ischemic attack (TIA) or minor ischemic stroke (IS). Adding clopidogrel to aspirin may yield more beneficial outcomes than aspirin mono-therapy; meanwhil...
Aspirin desensitization is increasingly recommended for the treatment of aspirin-exacerbated respiratory disease (AERD). The objective of this study is to systematically review the efficacy and safety...
Aspirin desensitization and treatment benefits most patients with aspirin-exacerbated respiratory disease (AERD), although some patients fail therapy. Our objective was to assess whether recent endosc...
Aspirin reduces cardiovascular disease and/or stroke risks. However, perioperative aspirin use remains controversial. We assessed the efficacy of ultrasonography to facilitate video-assisted thoracic ...
Aspirin is one of the most frequently used drugs worldwide and is generally considered effective for the secondary prevention of cardiovascular disease. By contrast, the role of aspirin in primary pre...
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 salicylate derivative and anti-inflammatory analgesic with actions and side effects similar to those of ASPIRIN.
