Cardiovascular events and death after catheter ablation in very old patients with nonvalvular atrial fibrillation.

Background: Catheter ablation of atrial fibrillation (AF) is recommended for selected older patients. However, the preventive effects of AF ablation on cardiovascular events and death remain unclear, especially in older patients. This study aimed to investigate the impact of AF ablation on the incidence of cardiovascular events and death in very old nonvalvular AF (NVAF) patients.

[Systemic inflammation in COPD and asthma: similarities and differences].

While recent studies have shown that patients with COPD and patients with asthma exhibit evidence of airway and systemic inflammation, markers of systemic inflammation have not been compared between the two diseases. To evaluate circulating inflammatory markers, blood was sampled from 111 patients with COPD, 75 control subjects and 46 asthmatic patients (some of whom were smokers). Measurements of WCC, serum levels of fibrinogen, high-sensitivity c-reactive protein (hs-CRP), interleukin-8 (IL-8), interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-alpha), transforming growth factor (TGF)-beta1, tissue inhibitors of metalloproteinase (TIMP)-1, neutrophil elastase and alphal-antitrypsin (alpha1-AT) were done.
