Raynaud syndrome, also known as Raynaud's phenomenon, is a medical condition in which the spasm of small arteries causes episodes of reduced blood flow to end arterioles. [1] Typically the fingers, and, less commonly, the toes, are involved. [ 1 ]
Chronic vasoconstriction is associated with hypertension, a major risk factor for cardiovascular diseases such as heart attack and stroke. Moreover, impaired blood flow resulting from abnormal vasoconstriction may contribute to tissue ischemia, which can be observed in conditions like Raynaud's disease.
Raynaud’s phenomenon, which causes parts of the body like the fingers and the toes to go cold and numb, likely stems from two genes, a study published Thursday in the journal Nature ...
Raynaud's phenomenon is frequently the first manifestation of CREST/lcSSc, preceding other symptoms by years. Stress and cold temperature induce an exaggerated vasoconstriction of the small arteries, arterioles, and thermoregulatory vessels of the skin of the digits. Clinically this manifests as a white-blue-red transition in skin color.
The disease was characterized by burning pain in the toes and soles of the feet, accompanied by foot redness, congestion, and edema; a few patients had fever, palpitations, headache, and joint pain. 60.6% of patients had a common cold before the onset of erythromelalgia and 91.2% had pharyngitis.

Variant angina is caused by vasospasm, a narrowing of the coronary arteries due to contraction of the heart's smooth muscle tissue in the vessel walls. [3] In comparison, stable angina is caused by the permanent occlusion of these vessels by atherosclerosis, which is the buildup of fatty plaque and hardening of the arteries. [4]
Other uncommon causes are coarctation of the aorta, [4] Trousseau disease [medical citation needed] and Buerger's disease (thromboangiitis obliterans), [5] in which vasculitis occurs. Raynaud's phenomenon functional vasospasm. [clarification needed] It is distinct from neurogenic claudication, which is associated with lumbar spinal stenosis. It ...
