How is peripheral arterial disease diagnosed?

So, peripheral tear disease is a very common pathology and is many times under-diagnosed, so that means that many people who have peripheral tear disease, or at least the basis of peripheral tear disease, don't even know that they have it. And actually, I'm not very worried about these people, the important thing is to diagnose the pathology when the symptoms come, especially when we're talking about critical limb ischemia. So it means that, you know, more or less everyone who has heart problem, I mean, occlusions of the vessels at the level of the heart with peripheral, you know, disease at the level of the coronary arteries, for example, they went underwent to a stenting procedure, it's very likely that we'll have also some degree of peripheral tear disease. But at the same time, the people who need to be screened are the ones who have symptoms. As I said before, you can have claudication, so it means that people can't walk very far because then cramps come and affect the calves, or it can be, as I said, critical in the skin when people, especially on dialysis and diabetic people, develop these ulcers at the level of the feet. and sometimes these ulcers are a bit naughty, I mean they stay also between the toes in places where they're not very visible and it's not very easy to spot them, so it's very important for these people to go for a very good look at the feet especially in winter when you know the socks are covering and it's more difficult to look at the toes.
