Epidemiological studies had been demonstrated that subclinical cardiovascular disease in one vascular bed is associated with the presence of clinical disease in another bed; as well as subsequer cardiovascular and total mortalities. Degree of peripheral vascular disease(PVD) in the legs as measured non invasively are common in old adults without overt signs and symptoms of PVD .an ankle —arm index has been shown to be a strong predictor of total cardiovascular morbidity and mortality in those without prior history of clinical cardiovascular disease at the baseline examination.
A cross sectional study done in IBN AL NAFEES teaching hospital for cardiology and cardiac Surgery. from 1st of June 2015 to 30th of Feb. 2016, for different age groups and multiple different risk factors (smoking, D.M, hypertension, family history of Ischemic heart disease, previous Ischemic heart disease,, hyperlipidemia) have their ankle-arm index measured by Doppler study and reported as abnormal (<0.9)and normal (>9). Then ‘ their coronary angiographic findings were obtained and correlated to the level of Ankle Brachial Index .
Study showed that 18 patients with low ABI value have abnormal angiographic findings (100%) i.e. High specificity; while 28 patients with normal ABl value proved to have coronary artery disease by (39.1%) i.e. Low sensitivity; but on the other hand low ABI significant relation for both multiplicity and severity of coronary disease diagnosed by angiography (p value 0.0001) for both.
Ankle-brachial index (ABI) index despite it is easy, quick and inexpensive bed side test for cardiovascular diseases it is of low sensitivity ;but its high specificity.
