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.
