Does aspirin prevent blood clots?
I have been unable to unearth any definitive research that says it does. Medical opinion is divided. There is no doubt that it confers certain benefits on the arterial side of the cardiovascular system since it reduces the incidence of first heart attacks if taken daily for long periods. It should be pointed out that the arterial side of the cardiovascular system can also be affected by thrombosis, although to a much lesser extent than the venous part of the system. Arterial clotting has been closely linked to platelet adhesion. Aspirin and other natural substances can help reduce this. Some medical researchers feel that aspirin’s beneficial influence in the venous system is minimal. A study of 300 high-risk passengers recorded a 4.8% incidence in the control group and a 3.6% incidence in those taking aspirin. Clearly aspirin had some value in this instance. (Belcaro et al: Angiology Vol 230, 2002). Are only long haul passengers at risk? A study by the UK-based Aviation Health Institut
