Inflammation plays an essential role in the development and progression of atherosclerotic lesions. Cytokines of the interleukin-1 family are central regulators in immunoinflammatory mechanisms. In the present work, the role of interleukin 1 (IL-1) and IL-1 receptor antagonist (IL-1RN) gene polymorphisms as susceptibility markers for acute coronary syndrome(More)
BACKGROUND The role of thrombolytic therapy (TT) and percutaneous coronary interventions (PCIs) in subgroups of patients with right ventricular infarction (RVI) has not been evaluated. METHODS AND RESULTS We risk-stratified 302 patients with RVI into three subsets upon admission. Class A (n=197) comprised patients without right ventricular (RV) failure,(More)
BACKGROUND Pregnancy can cause life-threatening complications in women with mitral stenosis. Frequently, there is an urgent need to increase the mitral valve area mechanically. In selected cases, percutaneous mitral balloon valvotomy (PMBV) has emerged as a safe and effective alternative to surgical commissurotomy. HYPOTHESIS The study evaluates the(More)
Recent studies provide evidence on the emerging role of the SOCS1 gene in the development and progression of atherosclerotic lesions. This gene encodes for the suppressor of the cytokine signaling-1 protein that interacts directly with the Janus kinases that are essential intracellular mediators of the immune cytokine action. The aim of this study was to(More)
AIM Was to evaluate the role of seven matrix metalloproteinase (MMP) polymorphisms in the genetic susceptibility to develop myocardial infarction in Mexican individuals. METHODS Seven polymorphisms in the MMP genes were genotyped by 5' exonuclease TaqMan genotyping assays in 300 patients with myocardial infarction and 300 healthy unrelated controls. (More)
The aim of the present study was to establish the role of IL-6 and TGF-β1 gene polymorphisms in the risk of developing in-stent restenosis. Two IL-6 [rs1800796 (-572 G>C), rs2069827 (-1426 T>G)] and two TGF-β1 [rs1800469 (-509 T>C), rs1800470 (T29C)] gene polymorphisms were analyzed by 5' exonuclease TaqMan genotyping assays in a group of 244 patients, who(More)
BACKGROUND Lipoprotein (Lp(a)) and homocysteine (Hcy) are independent risk factors for coronary artery disease (CAD). Hcy promotes the release of free apo(a) from Lp(a). The high fibrin affinity of free apo(a) inhibits plasminogen binding and plasmin generation. Hyperhomocysteinemia can result from a less active variant of methylene tetrahydrofolate(More)

BACKGROUND Clopidogrel is a pro-drug and its intestinal absorption is limited by the P-glycoprotein encoded by the ABCB1 gene. It is metabolized hepatically by cytochrome P450 enzymes encoded by CYP genes to produce an active metabolite that antagonizes the P2Y12 platelet receptor. Some patients exhibit poor clopidogrel responsiveness due to polymorphisms,(More)
