[Primary thrombosis of the anterior descending in a patient with antiphospholipid antibody syndrome].

Antiphospholipid antibody syndrome is a heterogeneous clinical and biochemical entity. We present the case of a young male with history of venous thromboembolism. This time he presents because of chest ischemic pain associated with ST segment elevation.

[Aortic valve calcification prevalence and association with coronary risk factors and atherosclerosis in Mexican population].

Objetive: The prevalence of aortic valve calcification (AVC), strongly influenced by ethnicity, is unknown in Mexican population. The aim of this study was to investigate the prevalence of AVC and its associations with cardiovascular risk factors and coronary artery calcification (CAC), in Mexican subjects.

Methods: In 1,267 subjects (53% women) without known coronary heart disease, aged 35 to 75 years, AVC and CAC were assessed by multidetector-computed tomography using the Agatston score.

Angiographic study of upper limb vascularization in a large cohort of hemodialysis patients with critical hand ischemia.

Background: Critical hand ischemia (CHI) is a not rare condition in patients with end-stage-renal-disease on hemodialysis (HD), and presents devastating consequences due to its impact on life quality. In HD patients CHI may be related to three main conditions: obstruction of the big upper limb arteries, obstruction of the small hand and finger arteries, and the steal effect of a hemodialysis access. The aim of this study was to describe the angiographic pattern of upper limb vascularization and associated cardiovascular risk factors, in a large cohort of consecutive HD patients with CHI studied in our center.

Radiological anatomy of upper limb arteries and their anatomical variability: implications for endovascular treatment in critical hand ischemia.

Critical hand ischemia (CHI) is a quite uncommon but highly disabling condition, generally caused by chronic occlusive arterial disease. For a correct approach to the endovascular treatment of these patients, good knowledge of the normal vascular anatomy and of the most frequently encountered vascular anatomical variations is of paramount importance. In the present paper a description of the normal vascular anatomy of the upper limb and of the most commonly encountered anatomical variations is provided, focusing on the implications for endovascular treatment of patients with CHI.

Fatty liver largely explains associations of subclinical hypothyroidism with insulin resistance, metabolic syndrome, and subclinical coronary atherosclerosis.

Background: The association of subclinical hypothyroidism (SCH) with insulin resistance, metabolic syndrome (MS), and coronary atherosclerosis is uncertain.

Objective: To investigate the role of increased intrahepatic fat in the association of SCH with insulin resistance, MS, and coronary atherosclerosis.

Design, Patients, And Methods: We conducted a cross-sectional study in a sample of 753 subjects (46% males) aged 35-70 years with no history of diabetes, renal, hepatic, thyroid, or coronary heart disease, and were participants of the Genetics of Atherosclerotic Disease study.
