Acute ischemic stroke: behaviour of granulocyte membrane fluidity and cytosolic Ca2+ content at baseline and after in vitro activation
Oxidative stress in young subjects with acute myocardial infarction: evaluation at the initial stage and after 12 months.
In 105 subjects (97 men and 8 women) aged <46 years (mean age 39.6 ± 5.5 years), with recent acute myocardial infarction (T1), thiobarbituric acid reactive substances and total antioxidant status were determined; NO production was evaluated by measuring the nitrite and nitrate (NOx) concentration. The patients with acute myocardial infarction were subdivided according to the main risk factors, number of risk factors, and extent of coronary lesions. The evaluation was repeated after 12 months (T2). In these subjects, thiobarbituric acid reactive substances and NOx were significantly increased and total antioxidant status was significantly decreased at T1. In single risk factor, only NO m…
Valve prosthesis-patient mismatch: hemodynamic, echocardiographic and clinical consequences
OBJECTIVES: The purpose is to evaluate in vivo at rest and under stress conditions hemodynamic performance of the small size St. Jude Medical Regent (SJMR) prosthetic valve in patients with a body surface area (BSA) of 1.8 ± 0.11 m(2) and to define the role of valve prosthesis- patient mismatch on left ventricular mass regression following aortic valve replacement. METHODS: We evaluated 25 cases (12 males and 13 females, mean age 65.2 ± 8 years) of aortic valve replacement (17 mm SJMR in three cases and 19 mm SJMR in 22 cases). All the patients underwent at rest Doppler echocardiography before and after surgery and both basal and dobutamine stress echocardiography (DSE) at follow-up. The me…
Diagnosis and definition of biventricular non-compaction associated to Ebstein's anomaly
Abstract Background Non-compaction of ventricular myocardium is a rare congenital cardiomyopathy characterized by the presence of an extremely thickened endocardial layer with prominent trabeculations and deep recesses in communication with ventricular chamber and determining the typical spongeous aspect. The diagnosis of non-compaction of ventricular myocardium is possible through the identification of morphological alterations by echocardiographic evaluation. Ebstein's anomaly is a rare congenital cardiac disease, defined as the significant apical displacement of the part of the tricuspid valve causing significant tricuspid regurgitation and reduction of the functional right ventricle, ri…

THE ROLE OF INFLAMMATION IN TYPE A AORTIC DISSECTION: A PILOT STUDY
Type A aortic dissection (TAAD) is a severe cardiovascular disease with high mortality rates. Current evidence suggests inflammation as the main mechanism of its complex pathophysiology. Accordingly, in this study the eventual presence of inflammatory cells in aorta specimens and any contribution of these cells in both apoptosis and metalloproteinase levels were assessed. The potential relationship between plasma inflammatory molecules and TAAD was also detected. In addition, implication in TAAD susceptibility of ten common and functional single nucleotide polymorphisms (SNP)s of six candidate genes (CCR5, TLR4, ACE, eNOs, MMP-9 and −2) was determined. Thus, histo-pathological and immunois…
