Overview

In patients with ischemic heart disease, prophylactic low dose aspirin prevents arterial thrombosis by irreversible inactivation of platelet aggregation.[1][2][3][4]

Aspirin

Mechanisms of Benefit

  • Aspirin is a potent anti-platelet agent.
  • Aspirin induces an irreversible functional defect in platelets by inhibiting cyclo oxygenase (COX-1) and subsequently suppressing the activation of thromboxane A2 that is responsible for platelet aggregation.[5]
  • Aspirin has shown to improve endothelial function and at high doses reduce acute phase reactants.

Indication

All patients with chronic stable angina, aspirin unless contraindicated should be started at 75 to 162 mg/day and continued indefinitely.[3]

Contraindications

  • Gastrointestinal bleed
  • Aspirin hypersensitivity (triad of rhinitis, asthma and polyposis)
  • Coagulation disorder
  • Uncontrolled hypertension[6]

Dosage

  • A dose range of 75 to 162 mg/day of aspirin[4] appears to be effective and is associated with lower risk of gastrointestinal bleeding.
  • In comparison to a dose range of 160-325 mg/day, a lower dose of aspirin (75-162 mg/day) has a higher efficacy for secondary prevention.
  • Aspirin improves endothelial function and at higher doses (300 mg/day) reduce the circulating levels of C-reactive protein.[7]

Drug Interactions

Use of warfarin in conjunction with aspirin and/or clopidogrel is associated with an increased risk of bleeding and therefore, close monitoring is required.

Adverse Effects

A higher dose of aspirin is associated with increased risk of gastrointestinal bleed.[3]

Supportive Trial Data

  • Meta-analysis (2002) of 140,000 patients from the Antiplatelet Trialists’ Collaboration showed that aspirin (75-325 mg/day) reduced the rate of subsequent myocardial infarction, stroke, and death in patients with history of angina pectoris, myocardial infarction, CABG, and stroke.[4]
  • Meta-analysis (2000) of 24 randomized controlled trials involving 66,000 patients showed significant increase in the incidence of gastrointestinal hemorrhage associated with long term aspirin therapy. There was no supportive evidence of lower dose or modified release formulations reducing the incidence of GI bleed.[8]
