Prothrombotic gene variants as risk factors of acute myocardial infarction in young women
Abstract Background 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. Methods We studied Factor V Leiden, FII G20210A, MTHFR C677T and beta-fibrinogen -455G>A variants by real-time PCR in 955 young AMI (362 females) and in 698 AMI (245 females) patients. The data were compared to those obtained in 909 unrelated subjects (458 females) from the general population of the same geographical area (southern Italy). Results In young AMI females, the allelic frequency of either FV Leiden and of FII G20210A was signif…
Buerger`s Disease and Hyperhomocysteinemia: Is there a Relationship?
Thromboangiitis obliterans, also known as Buerger's disease, is a cause of juvenile lower limb ischaemia. Buerger's disease is idiopathic and one of diagnostic criteria is the absence of atherosclerotic risk factors other than smok- ing. A possible involvement of thrombophilia has been investigated and the role of hyperhomocysteinemia is still matter of discussion. We describe 9 patients with Buerger's disease followed-up for the past 3 years. We found a significant in- crease in circulating homocysteine levels (mean: 31.6 in patients vs 8.2 μmol/L in control subjects). We also analyzed the C677T mutation of MTHFR; 5/9 Buerger's patients were heterozygotes and 4/9 homozygotes for the mutati…
