The prognostic significance of serum glucose levels after the onset of ventricular arrhythmia on in-hospital mortality of patients with acute coronary syndrome.

Background: Several studies have illustrated the role played by serum glucose levels in cardiovascular morbidity and mortality in general and, more particularly, after an acute coronary event.

Aim: The aim of this study was to evaluate the impact of serum potassium and glucose levels on in-hospital mortality in patients with ischemic heart disease, who exhibited severe ventricular arrhythmia.

Methods: We enrolled 162 consecutive patients who were referred to our institution for an acute coronary event and presented with sustained ventricular tachycardia or ventricular fibrillation during the first 24 hours of hospitalization.

Long-term fish consumption is associated with protection against arrhythmia in healthy persons in a Mediterranean region--the ATTICA study.

Background: Dietary habits have long been associated with many manifestations of cardiovascular disease.

Objective: We sought to investigate whether a diet enriched with fish and n-3 fatty acid consumption are associated with changes in the potential duration of the electrical action, as represented by the QT duration on a resting electrocardiogram, in a population-based sample of Greek adults.

Design: During 2001 and 2002, we randomly enrolled 1514 men (18-87 y old) and 1528 women (18-89 y old) stratified by age and sex distribution (in the 2001 Greek census) from the Attica area, Greece.
