EnglishLow ankle-brachial index (ABI) levels are associated with increased risk of all-cause and cardiovascular mortality in middle-aged and older adults. We evaluated the association between low ABI and all-cause and cardiovascular mortality in elderly patients living in nursing homes. In 632 subjects (mean age 82.1 +/-7.4 years, 137 men) living in 3 municipal nursing homes, ABI, prevalent cardiovascular diseases, and conventional risk factors were evaluated at baseline in 1998. After a 3-year follow-up the relation between a low ABI and mortality outcomes was evaluated by using multivariable Cox proportional hazards analysis. A low ABI (<0.90) was observed in 177 participants (28%). After 3 years, 304 subjects (48.1%) died; death occurred in 53.6% of those with low ABI and in 45.9% of those with normal ABI. No significant relation between low ABI and all-cause (hazard ratio [HR] 1.1, 95% confidence interval [CI] 0.7-2.0) or cardiovascular mortality (HR 1.3, 95% CI 0.8-2.1) was observed. Among elderly patients living in nursing homes, there is a high prevalence of low ABI, which is not related to all-cause and cardiovascular mortality.

| Abstract: | Low ankle-brachial index (ABI) levels are associated with increased risk of all-cause and cardiovascular mortality in middle-aged and older adults. We evaluated the association between low ABI and all-cause and cardiovascular mortality in elderly patients living in nursing homes. In 632 subjects (mean age 82.1 +/-7.4 years, 137 men) living in 3 municipal nursing homes, ABI, prevalent cardiovascular diseases, and conventional risk factors were evaluated at baseline in 1998. After a 3-year follow-up the relation between a low ABI and mortality outcomes was evaluated by using multivariable Cox proportional hazards analysis. A low ABI (<0.90) was observed in 177 participants (28%). After 3 years, 304 subjects (48.1%) died; death occurred in 53.6% of those with low ABI and in 45.9% of those with normal ABI. No significant relation between low ABI and all-cause (hazard ratio [HR] 1.1, 95% confidence interval [CI] 0.7-2.0) or cardiovascular mortality (HR 1.3, 95% CI 0.8-2.1) was observed. Among elderly patients living in nursing homes, there is a high prevalence of low ABI, which is not related to all-cause and cardiovascular mortality. |
