The pressure cuff is used subsequently for every arm and the systolic pressures are registered. This test is non invasive and places the patient in a supine position. One of the criticisms received by the model is referred to its lack of accuracy, with false negatives, in the cases of patients with hardened, incompressible arteries. It is used as diagnostic mean with a sensitivity of 90% and a specificity of 98% in detecting stenosis but also to monitor medical treatments or recovery after angioplasty. The Ankle Brachial Index (ABI) calculator is basically defined by the ABI formula, which is the systolic pressure at the ankle divided by the systolic pressure at the arm. The application of this blood pressure test is advised by medical groups for all patients over 70 years of age and all patients over 50 if smoking or diabetic. Subsequent studies have proved that the ABI test is a specific and sensitive measure in the diagnosis of PAD. This is a health tool used in the diagnosis of peripheral arterial disease (PAD) and also in the risk stratification for cardiac events, all dependent of the systolic pressure values. How does this Ankle Brachial Index (ABI) for PAD risk calculator work? ![]()
