Executive Summary

“Aspirin remains the cornerstone of anti platelet therapy in patients with cardiovascular diseases. It decreases mortality and recurrence of cardiovascular events when used as acute therapy following acute coronary syndrome, thrombotic stroke and Kawasaki’s disease. It has proven benefits in secondary prevention in acute coronary syndrome, stable angina, revascularization, stroke, TIAs and atrial fibrillation. As such Use of Aspirin in ST elevation Myocardial Infarction or Acute Coronary Syndrome offers a substantial benefit regarding mortality, re-infarction and stroke.
Use of Aspirin in primary prevention is associated with clinical benefit only in high risk individuals. The physicians starting an individual for a life long low dose aspirin therapy for primary prevention must calculate the overall risk of the individual and only high risk patients should be advised to start low dose aspirin Therapy.
Patients with diabetes mellitus should also be put on low dose aspirin therapy if there are no contra indications.
Patients with high blood pressure may be started on low dose aspirin only when their blood pressure is well controlled for a prolonged period of time.
The role of Aspirin in prevention of deep vein thrombosis in major surgery and Air travel is still under investigation. Another emerging indication is prevention of colorectal cancer and other major cancers including reduction in distant metastasis.
Enteric coated aspirin preparations developed to attenuate local gastric erosion and minimize this side effect are preferred for long term use in patients on low dose aspirin therapy. The concept of aspirin resistance is still an emerging and important clinical question which needs to be studied further
These guidelines also give some details of combination with Clopidogrel in acute coronary syndrome and coronary stenting as well as Coronary Artery Bypass Graft Surgery (CABG). “
