Dual antiplatelet therapy is currently recommended for all patients with acute coronary syndromes, independent of whether they receive pharmacological treatment or undergo percutaneous coronary intervention. Antiplatelet agents are the cornerstone of pharmacological treatment in interventional cardiology...

Catheter ablation has emerged as an important therapy for the management of drug refractory symptomatic paroxysmal and persistent atrial fibrillation (AF). Although the elderly account for the majority of patients with AF, limited data exists regarding the use of catheter ablation for elderly patients with AF. As AF ablation has become more widespread, ablation techniques have improved and the complication rate has decreased...

Osteoporosis is a growing problem in an ageing society. It affects women of post-menopausal age, as well as elderly subjects of both sexes, often with dysfunction of the cardiovascular system or with an increased risk of circulation disorders. It has been found that the mortality rate of subjects with osteoporosis is comparable to that of patients suffering from such diseases as obturative pulmonary disease or myocardial ischaemia...

Atrial conduction disturbances are a known substrate of re-entrant atrial arrhythmia, and their detection is important for the selection of proper therapy. Time-domain analysis of P-wave in signal-averaged ECG (SA-ECG) recorded from chest leads is an accepted method evaluating inhomogeneity of atrial excitation, predictive for atrial arrhythmias. Biatrial (BiA) pacing created a new therapeutic option for patients with atrial arrhythmias...

The aim of this study was to evaluate the association between atrial fibrillation and atrial dilation and the spatial distribution pattern of connexin 40 in the atria of patients with coronary heart disease...

Analysis of high gain, signal-averaged (SA) ECG is an accepted method evaluating abnormalities of atrial repolarization — the presence of late potentials (ALP) — predictive for atrial arrhythmias. Recently it has been proven that the location of atrial leads has an influence on atrial activation and modifies the risk of atrial arrhythmias...

The aim of the study was to evaluate plasma natriuretic peptides (NPs): atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) concentrations in patients with paroxysmal, persistent and permanent atrial fibrillation (AF)...

Despite the advancements in pharmacological and non-pharmacological management of atrial fibrillation (AF) observed during last decades, available treatment modalities and predictors of their success are still far from optimal. Understanding of pathophysiological mechanisms underlying AF and assessment of atrial electrophysiological properties using easily available non-invasive diagnostic tools such as surface ECG are essential for further improvement of patient-tailored treatment strategies..

It is known that overt diabetes as well as chronic hyperglycaemia can lead to atrial fibrillation. A P wave  dispersion (PWD) represents heterogeneity in atrial refractoriness.  To investigate PWDs in patients with pre-diabetes...

The case of 61 year-old woman with congenital coronary artery fistula connecting left main coronary artery and the right atrium is presented. The patient was admitted to the Cardiology Department because of the first atrial fibrillation episode. During hospitalisation the congenital heart defect was diagnosed thanks echocardiography and multi-slice computed tomography...
