Methods: long-term mortality after 12-year follow-up in 125 subjects with CHF and 1,143 subjects without CHF was studied. Comorbidity was evaluated using CCI. Findings: in elderly subjects stratified for CCI (1-3 and >= 4), mortality was higher in non-CHF subjects with CCI >= 4 (52.4% versus 70%, P < 0.002) but not in those with CHF (75.9% versus 77.6%, P = 0.498, NS). Cox regression analysis on 12 years mortality indicated that both CCI (HR = 1.15; 95% CI = 1.01-1.31; P = 0.035) and CHF (HR = 1.27; 95% CI = 1.04-8.83; P = 0.003) were predictive of mortality. When Cox analysis was performed by selecting the presence and the absence of CHF, CCI was predictive of mortality in the absence but not in the presence of CHF. Conclusion: CCI does not predict long-term mortality in elderly subjects with CHF.
