However, the risk of thromboembolism (TE) is not the same for all AF patients. While ECG rhythm strips of patients with AF are (...) generally indistinguishable, it has long been known that AF in younger patients without co-morbid factors (“lone AF”) carries an extremely low risk for TE, whereas AF in older patients in the presence of specific comorbidities carries a high TE risk. 1,2 Thus, AF alone cannot sufficiently explain the risk. However, it has also been long known that older patients with conditions such as hypertension, diabetes and atherosclerotic disease also have an important risk for stroke, even in the absence of AF

It is higher in men than women. 4 One of the most important causes of morbidity in patients with CHD is the development of cardiac arrhythmias, in particular tachyarrhythmias.

Gamma-glutamyl transferase (GGT) is a liver enzyme associated with oxidative stress that is postulated to have a link to AF occurrence.
