中風後病人，施行簡易的ABI測試(量測腳踝及手肘血壓值)，可作為再發中風、心血管疾病的風險評估及是否需更積極治療的依據。
此類病人，即使是沒有周邊動脈硬化的症狀(如運動後腿腳會痛)，也以表示其周邊動脈已有動脈硬化粥形成及阻塞，Sen"究發現1/4中風後的病人有硬化，後續兩年，他發生心血管疾病的機率是沒有的病人的4倍，中風為5倍。
Ankle Test Tells Heart Risk After Stroke |
ABI Test Detects Asymptomatic Peripheral Artery Disease |
The ABI is a simple test that measures the blood pressure at the ankle and
compares it to the blood pressure at the arm. If the ankle blood pressure is
significantly lower, it indicates that plaque is clogging the outer arteries of
the body. This is PAD. |
About a fourth of the TIA/stroke patients in the Sen study did have PAD.
Over the next two years, they were four times more likely to suffer a TIA,
heart attack, or heart-related death. And they were five times more likely to
suffer a stroke. |
