Abstract
Long term corticotherapy and obstructive ventilation disorder are independent risk factors for new atrial fibrillation onset. Anticoagulation therapy if indicated is suitable for COPD patients as well as for patients with respiratory infections in absence of massive hemoptysis.
Drug interaction should be respected. In intensive care with the need of invasive procedures switch to LMWH or anticoagulants with short half life could be helpful.
In patients with less advanced stages of tumors is anticoagulation therapy appropriate while these patients are in greater risk of venous tromboembolism. Low molecular weight heparin seems to be safer and more efficient compared to vitamin K antagonists.
Sleep apnea patients have high prevalence of atrial fibrillation, therefore especially obese patients should diagnosed properly.
