ABI 正常値●足関節上腕血圧比(ABI)は,足関節収縮期血圧(後脛骨動脈・足背動脈のいずれか高い方)を,左右のうち高い方の上肢収縮期血圧で除して算出される.ABIが0.90以下では下肢主幹動脈の狭窄や閉塞が,1.40より高値では動脈の高度石灰化が疑われる.最近のガイドラインでは,1.00〜1.40が標準値とされ,0.91〜0.99はボーダーラインとされている. 必修cardiology HirotoShishido

Leriche syndromeThigh claudication is suggestive of occlusive disease of the ipsilateral external iliac artery or its more distal branches (ie, common femoral, superficial femoral, profunda femoris arteries).
Accompanying ☆★impotence and/or ☆gluteal claudication suggests ☆more proximal aortoiliac occlusion (so-called Leriche syndrome), which, in addition to affecting the external iliac artery, also diminishes blood flow to the internal pudendal and gluteal branches of the internal iliac artery. cardiologysurgeryUWorld step2CK HirotoShishido
atheroembolic disease☆Invasive vascular procedures (eg,angiography, angioplasty, aortic surgery) can cause ☆cholesterol-containing debris from atherosclerotic plaques to become dislodged from large arteries (eg, the aorta during cardiac catheterization) and shower microemboli into the circulation.
Skin findings (eg, ☆livedo reticularis, blue toe syndrome) are the most common presenting signs.

the strongest risk factor for coronary heart diseasehighest→ ☆diabetes mellitus, noncoronary atherosclerotic disease, CKD
other major risk factors→ HTN, hyperlipidemia, smoking, ↑age, obesity, physical inactivity
Several studies have shown that diabetes mellitus is one of the strongest risk factors for coronary heart disease.
The risk of dying from coronary heart disease exceeds the risk of dying from any of the other listed causes, even in the absence of other major risk factors forcoronary heart disease. cardiologyUWorld HirotoShishido
