Aim. To identify whether Ankle/Arm Index (AAI) is a predictive factor for cardiovascular mortality in institutionalised elderly.
Methods. Design: longitudinal descriptive study. Setting: 2 large nursing homes in Turin, Italy. Subjects: 418 dependent elderly (83 males, 335 females, mean age 83.7±8.5 y, range 55-102) living in the nursing homes. Measurements: the prevalence of peripheral arterial disease (PAD) was evaluated using a Doppler Ultrasound measurement of AAI (Ankle/Arm blood pressure Index). Death causes according to ICD-9-CM were ascertained on patient’s clinical records.
Results. Diagnosis of PAD was made in 122 subjects (29.2%) with AAI <0.90. After a 3 year follow-up 203 patients (48.6%) died. The presence of PAD was not related to total mortality or to mortality for ischemic heart disease (IHD), cerebrovascular disease or other causes. IHD mortality was significantly and independently related to low haemoglobin values, previous cerebrovascular disease, polypharmacy and poor mobility conditions.
Conclusion. The prevalence of PAD is high in nursing home residents. AAI is not predictive for IHD mortality in this population. In very frail elderly traditional risk factors and PAD are less important predictors of death compared to poor functional status, nutritional factors and previous cardiovascular disease.
