Observational Study
Flow-mediated dilation is associated with cardiovascular events in non-valvular atrial fibrillation patients.
Atrial fibrillation is associated with multiple atherosclerotic risk factors and predisposes to cardiovascular events (CVE). Endothelial dysfunction is associated with atherosclerosis and independently predicts CVE. The aim of the study was to evaluate the association between endothelial dysfunction, as assessed by flow-mediated dilation (FMD), and CVE in AF patients. ⋯ In AF patients low FMD is associated with increased risk of CVE suggesting that impaired artery dilatation predisposes to atherosclerotic complications.

No previous nationwide study has examined whether there is a 'weekend effect' of higher mortality after admission for acute myocardial infarction (AMI) when percutaneous coronary intervention (PCI) is easily accessible. ⋯ This study showed that weekend admission for AMI was significantly associated with higher in-hospital mortality even in a setting where PCI was highly available.
