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.
