The aim of this study was to determine whether paroxysmal atrial fibrillation (PAF) and/or restoration to sinus rhythm with electric or pharmacologic cardioversion induce modifications to the coagulation system. Thirty-five patients with PAF undergoing either electric (n = 11) or pharmacologic (n = 24) cardioversion were studied. Fibrinopeptide A and(More)
OBJECTIVE The aims of this study were to compare a microsatellite polymorphism (PM) of matrix metalloproteinase (MMP)-9 in patients with carotid atherosclerosis and control population, and to assess the relationship between this PM and plaque structure. METHODS AND RESULTS One hundred fifty patients referring to vascular diagnostic centers for suspected(More)
INTRODUCTION Experimental models and ex-vivo studies suggest a crucial role of some matrix metalloproteinases (MMPs) in the development of acute coronary syndromes, but expression levels of MMP-2, MMP-9 and TIMP-1 in human coronary plaques causing stable angina or an acute coronary syndrome have not been reported, yet. METHODS MMP-2, -9 and TIMP-1(More)
PURPOSE To investigate the short term effects of Doxycycline on MMP-2 and MMP-9. METHODS Short term effects of Doxycycline (100 mg B.I.D.) on plasma levels of MMP-2 and MMP-9 were investigated in 20 healthy subjects; the effects of Doxy, Acetylsalicylic acid, Nitrates, and Enalapril on MMP-9 release from were assessed in isolated polymorphonuclear cells.(More)
A polymorphism (PM) in the microsatellite of the promoter region of matrix metalloproteinase 9 (MMP-9), modulating its expression, could play a role in susceptibility to multiple sclerosis (MS). MMP-9 PM was determined in 95 patients with MS (MS Group) and 95 age- and sex-matched controls (Control Group). Comparison of allelic frequencies showed that a(More)
The aim of the study was to evaluate which pattern of coagulation indicators characterizes unstable angina and, particularly, its relationship with short-term prognosis. Forty patients with unstable angina (UA Group) at admission in the intensive care unit, 40 patients with chronic stable effort angina (SEA Group), and 20 age- and sex-matched healthy(More)
BACKGROUND Rotavirus is the major cause of acute gastroenteritis and severe dehydrating diarrhea in young children. METHODS To estimate the proportion of hospital admissions for rotavirus acute gastroenteritis and identify the circulating G and P genotypes among children under five years of age, we conducted a prospective observational study from January(More)
OBJECTIVE To determine the fatal and non-fatal cardiovascular event rate in patients with intermittent claudication treated with antiplatelet agents. METHODS AND DESIGN Patients with PAD-II stage Fontaine (n=223) and sex and age matched controls (n=446) were followed up from 1974 to 1998. All patients were treated with antiplatelet agents (aspirin, 325 mg(More)
BACKGROUND A relevant amount of patients with clinical suspect of sepsis is admitted and treated in medical wards (MW). These patients have a better prognosis but are older and with more comorbidities compared to those admitted to intensive care units (ICU). Procalcitonin (PCT) is extensively used in emergency departments for the diagnosis of sepsis, but(More)
Intima-media thickening (IMT) of carotid arteries and constrictive remodeling (CR) of atherosclerotic plaques are vascular pathologic characteristics that precede the onset of vascular events. SMC migration and proliferation are linked both to IMT and CR and are matrix metalloproteinase 9 (MMP-9) dependent. A genetic polymorphism (PM) of MMP-9, a CA (13-27)(More)
