Rates of cardiovascular disease and mortality with abnormal 2 Several epidemiologic studies have reported up to four-fold increased The predictive value of ABI in cardiovascular morbidity and mortality is similar to that of traditional Framingham risk factors. Independent risk factor for cardiovascular disease, includingįatal and nonfatal complications. Robust data support that PAD directly relates to cardiacĪnd cerebrovascular morbidity and mortality independent Specificity of 100%, relative to contrast angiography, forĭetecting a stenotic lesion of at least 50% in the limb. An ABI of 0.9 or less has a sensitivity of 95% and a.Is between 0.4 and 0.9, and an ABI 1.4 is also consideredĪbnormal and is suggestive of noncompressible vessels. PAD is graded as mild to moderate if the ABI ≤ 0.9.5,6 An ABI value of 0.91 to 0.99 is considered “borderline.” The patient is diagnosed with PAD when the ABI is.The American Heart Association, ABI ratios are interpreted Management from the American College of Cardiology and ABI INTERPRETATIONĪccording to the published practice guidelines for PAD Hg in healthy individuals as a result of higher peripheral Pressure will exceed the brachial pressure by 10 to 15 mm Pressure by the highest brachial systolic pressure. The ABI isĬalculated for each leg by dividing the highest ankle systolic The test requires that the systolicīlood pressure be recorded in both brachial arteries and inīoth dorsalis pedis and posterior tibial arteries. Should be obtained after the patient has been supineįor 5 to 10 minutes. Of resources and investment-only a simple blood pressureĬuff and a handheld continuous-wave 5- to 10-MHzĭoppler probe is needed. Test is underutilized even though it requires a minimal use Marker of atherosclerosis and is a predictor of futureĬardiovascular disease and all-cause mortality. To that at the brachial arteries if abnormal. Ratio of systolic blood pressure at the ankle arteries relative Test that can identify patients with PAD by determining the In 1950, Winsor was first to use ABI measurements in Normally screened with ankle-brachial index (ABI) measurements Tibial pulses have a sensitivity and specificity of 63%Īnd 99%, repectively. Of whether a diagnosis of coronary artery disease hasĪlready been established. With PAD are attributed to the coronary vasculature regardless Most of the fatal or disabling clinical events associated Reliable physical findings are diminished or absent pedal Skin color, poor hair growth, and cool skin. Vascular disease include absent or diminished pulses, abnormal Physical examination findings in patients with peripheral View of overall cardiovascular integrity and health. Without assessing the pedal pulse, which provides a window 1Ī thorough cardiovascular examination is incomplete Symptomatic PAD and many more remain asymptomatic. There are more than 2 million Americans who have There isĪ strong association among peripheral artery disease (PAD),Ĭoronary artery disease, carotid artery disease, and abdominal A diminished foot pulse may be the only clue thatĪ patient is at increased risk of cardiovascular death. Peripheral vascular disease, in whom diminished exerciseĬapacity may limit the development of exertional angina,Īnd in diabetic patients who often have faulty angina warning This is particularly important in patients with Predict that a patient is at a much higher risk of cardiovascularĭeath. Atherosclerosis is a systemicĭisease, so physical findings in other vascular beds can Indicate carotid stenosis, but there are no clear In the US, with cerebrovascular accident being Coronary artery disease is the leading cause of death
