Abstract Background: Several studies have associated elevated C-reactive protein (CRP) levels to the occurrence of atrial fibrillation (AF). We sought to estimate the frequency and prognostic impact of AF in patients with bacteremia, and to study the possible association between AF and C-reactive protein (CRP) in this population. Materials and ...

In patients with acute coronary syndrome (ACS), the presence of atrial fibrillation (AF) results in worse inpatient outcomes than in those without AF. Two electrocardiographic markers, maximum P wave duration (P(maximum)) and P wave dispersion (P(dispersion)), have been assessed because they reflect conduction abnormalities in patients with paroxysmal AF. b ...

Demodex folliculorum has been incriminated in the development of blepharitis although much controversy persist. Some authors suggest that Demodex is a direct pathogen in chronic palpebral conditions while others consider the saprophyte to be innocuous to skin. We conducted a prospective study of eyelashes in 48 patients with blepharitis (totally ...

Asymptomatic atrial fibrillation (AF) is common and may have the same prognostic implications as symptomatic AF. Among patients receiving dual-chamber pacemakers, it is now possible to quantify asymptomatic AF accurately. Most of these episodes are of short duration, often lasting only seconds to minutes and are called atrial high-rate episodes ...
