Prothrombotic gene variants as risk factors of acute myocardial infarction in young women
<p>Abstract</p> <p>Background</p> <p>Acute myocardial infarction (AMI) in young women represent an extreme phenotype associated with a higher mortality compared with similarly aged men. Prothrombotic gene variants could play a role as risk factors for AMI at young age.&...
