BACKGROUND: Congestive heart failure (HF) represents a major public health problem with an age-related increasing prevalence. Despite the high mortality and morbidity in elderly patients with HF, limited clinical and prognostic data are available for development of appropriate prevention and treatment strategies. METHODS: A cohort of 3327 outpatients consecutively enrolled in the Registry of Italian Network on Congestive Heart Failure by 133 cardiology centers was studied. Univariate and multivariate analyses were performed to compare patients <70 and > or =70 years old and to evaluate associations between clinical variables and the 1-year mortality rate and hospitalizations. RESULTS: With respect to the 2294 patients <70 years old, the 1033 (31%) elderly patients were significantly more likely to be female, to be in New York Heart Association (NYHA) class III-IV, and to have preserved left ventricular systolic function (ejection fraction >40%), an ischemic/valvular etiology, and atrial fibrillation/flutter. Elderly patients received angiotensin-converting enzyme inhibitors, beta-blockers, and anticoagulants less frequently than younger patients did. The 1-year mortality rate was significantly higher in patients > or =70 years old (22% vs 13.7%, P <.001). Age was an independent predictor of 1-year mortality, increasing 2.8% by each year of age. Independent predictors of 1-year mortality in elderly patients were (1) > or =1 hospital admission in the previous year (relative risk [RR] 2.09, 95% CI 1.51-2.87), (2) systolic blood pressure (RR 0.98, 95% CI 0.97-0.99), (3) NYHA class III-IV (RR 1.57, 95% CI 1.20-2.07), and (4) age (RR 1.028, 95% CI 1.001-1.056). CONCLUSIONS: Our study confirms that elderly patients (1) are seen in a more advanced stage of HF, (2) are less likely to receive evidence-based treatments, (3) show more frequently preserved systolic function, and (4) have a worse prognosis. Consequently, there is a need to develop more effective and targeted management strategies for this escalating health problem.

Abstract

BACKGROUND: Congestive heart failure (HF) represents a major public health problem with an age-related increasing prevalence. Despite the high mortality and morbidity in elderly patients with HF, limited clinical and prognostic data are available for development of appropriate prevention and treatment strategies. METHODS: A cohort of 3327 outpatients consecutively enrolled in the Registry of Italian Network on Congestive Heart Failure by 133 cardiology centers was studied. Univariate and multivariate analyses were performed to compare patients <70 and > or =70 years old and to evaluate associations between clinical variables and the 1-year mortality rate and hospitalizations. RESULTS: With respect to the 2294 patients <70 years old, the 1033 (31%) elderly patients were significantly more likely to be female, to be in New York Heart Association (NYHA) class III-IV, and to have preserved left ventricular systolic function (ejection fraction >40%), an ischemic/valvular etiology, and atrial fibrillation/flutter. Elderly patients received angiotensin-converting enzyme inhibitors, beta-blockers, and anticoagulants less frequently than younger patients did. The 1-year mortality rate was significantly higher in patients > or =70 years old (22% vs 13.7%, P <.001). Age was an independent predictor of 1-year mortality, increasing 2.8% by each year of age. Independent predictors of 1-year mortality in elderly patients were (1) > or =1 hospital admission in the previous year (relative risk [RR] 2.09, 95% CI 1.51-2.87), (2) systolic blood pressure (RR 0.98, 95% CI 0.97-0.99), (3) NYHA class III-IV (RR 1.57, 95% CI 1.20-2.07), and (4) age (RR 1.028, 95% CI 1.001-1.056). CONCLUSIONS: Our study confirms that elderly patients (1) are seen in a more advanced stage of HF, (2) are less likely to receive evidence-based treatments, (3) show more frequently preserved systolic function, and (4) have a worse prognosis.
