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 ]
In people with Raynaud’s phenomenon, cold temperatures or stress trigger spasms in the small blood vessels near the surface of the skin, causing the vessels to constrict and limit blood flow.
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 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.
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 ...
Physical activities often require prolonged, repetitive movements that place significant demand on the heart, lungs, and smaller stabilizing muscles, which degrade over time without consistent ...
The pain associated with microvascular angina is normally more intense and it lasts for longer periods of time compared to pain caused by other conditions. Many gastric conditions can cause chest pains (sub-sternal pain), while this is usually associated with consumption of food this is not always the case, and is a very common differential ...
Whether caused by night sweats or hormonal fluctuations, many women will find themselves snoozing less soundly during perimenopause. (Those 3 a.m. wake-ups are not a myth!)
