The major tissues affected are nerves and muscles, where irreversible damage starts to occur after 4–6 hours of cessation of blood supply. [4] Skeletal muscle, the major tissue affected, is still relatively resistant to infarction compared to the heart and brain because its ability to rely on anaerobic metabolism by glycogen stored in the cells may supply the muscle tissue long enough for ...
Bone pain originates from both the periosteum and the bone marrow which relay nociceptive signals to the brain creating the sensation of pain. Bone tissue is innervated by both myelinated (A beta and A delta fiber) and unmyelinated sensory neurons. In combination, they can provide an initial burst of pain, initiated by the faster myelinated ...
Beck's triad is a collection of three medical signs associated with acute cardiac tamponade, a medical emergency when excessive fluid accumulates in the pericardial sac around the heart and impairs its ability to pump blood. The signs are low arterial blood pressure, distended neck veins, and distant, muffled heart sounds. [1]
Every time the calf muscle contracts, one-way valves inside the leg veins open and blood gets pushed upwards towards the heart; when the calf muscle relaxes, the valves close, which prevents blood ...
The prognosis for patients with peripheral vascular disease due to atherosclerosis is poor; patients with intermittent claudication due to atherosclerosis are at increased risk of death from cardiovascular disease (e.g. heart attack), because the same disease that affects the legs is often present in the arteries of the heart.
According to guidelines, taking aspirin or clopidogrel is recommended to reduce AMI ("heart attack"), stroke, and other causes of vascular death in people with symptomatic peripheral artery disease. [20] It is recommended that aspirin and clopidogrel be taken alone and not in conjunction with one another (i.e., not as dual antiplatelet therapy
Rose's sign is a clinical sign in which the skin of one leg feels warm and stiff when pinched. It can occur in people with deep vein thrombosis due to oedema in the affected leg. [ 1 ] [ 2 ]
Tendonitis is one of the most common causes of pain in the foot or ankle. The muscles of the legs, feet and ankles are fixed to the bones by tendons, which are strong rope-like structures.
