Abstract

Permanent AF is characterized by an increased mortality in elderly subjects with CHF. Moreover, AF increased the risk of mortality also in elderly subjects without CHF. Thus, we examined long-term mortality in community-dwelling elderly people with and without CHF. A total of 1332 subjects aged 65 and older were selected from the electoral rolls of Campania, a region of southern Italy. The relationship between AF and mortality during a 12-year follow-up in 125 subjects with CHF and in 1.143 subjects without CHF were studied. Elderly subjects showed a higher mortality in those with respect to those without AF (72.1% vs. 51.8%; p< 0.01). Similarly, elderly subjects without CHF showed a higher mortality in those with respect to those without AF (61.8% vs. 49.8%; p< 0.05). In contrast, elderly subjects with CHF showed a similar mortality in those with respect to those without AF (74.7% vs. 82.4%; p=. 0.234). Multivariate analysis shows that AF was predictive of mortality in all elderly subjects (Hazard Risk = HR = 1.39, 95% confidence interval (CI) = 1.25-2.82; p< 0.001). When the analysis was conducted considering the presence and the absence of CHF, AF was strongly predictive of mortality in elderly subjects without CHF (HR = 1.95, 95%CI = 1.25-4.51; p< 0.001) but not in those with CHF (HR = 1.12, 95%CI = 0.97-3.69; p=. 0.321). We concluded that AF is able to predict long-term mortality in elderly subjects. Moreover, AF is strongly predictive of long-term mortality in the absence but not in the presence of CHF.
