The American College of Cardiology and the American Heart Association launched different guidelines related to peripheral arterial disease in order to help doctors and all healthcare professionals to treat in a better way this common condition. According to statistics, more than 12 million people suffer from Peripheral Arterial Disease (PAD) in the United States. PAD is a really serious illness, since it can cause amputation of the extremities, rupture of an aortic aneurysm, severe hypertension, kidney failure, but also heart attack, stroke, and cardiovascular death. It is a disease in which arteries supply blood to the arteries outside the heart, to parts such as legs, feet, kidneys, and intestines. This arterial disease can cause damages to physical health of people, by diminishing for instance their ability to walk. According to experts, the new guidelines supply a succinct diagnostic and treatment guidebook for patients suffering from PAD and for physicians, doctors' assistants, nurse practitioners, and nurses who are now offering care to treat them. “A key source of the power of these recommendations is that they are so broad-based in their origin from every vascular specialty, as they attempt to reach a broad-based audience of clinicians. Everyone can use these Guidelines and a large segment of the public can benefit from them,” said Alan T. Hirsch, chairman of the writing committee. Some highlights of the guidelines include recommended questions and observations that can uncover hidden signs of peripheral arterial disease; recommendations on when an aneurysm should be treated with surgery or catheter-based therapy, as well as when “watchful waiting” is the best way; among other things.
