Dr. Lawrence Craven and clinical trial of aspirin

The antiplatelet effects of aspirin were first noticed by Dr. Lawrence Craven. He was first to describe the potential of aspirin to prevent heart attacks. Dr. Lawrence Craven, a California general practitioner, in 1948, notices that the 400 men he prescribed aspirin to hadn't suffered any heart attacks.

He published his results in a minor medical journal, the Mississippi Valley Medical Journal in 1953.

He also concluded that men suffered more heart attacks than women due to the fact that they were less likely to engage in the taking of medication. He regularly recommends to all patients and colleagues that "an aspirin a day" could dramatically reduce the risk of heart attack.

Dr. Lawrence was born in Iowa in 1883, and a graduate with a MD from the University of Minnesota College of Medicine and Surgery right before entering into service in the First World War.
