Arterial occlusion is a condition involving partial or complete blockage of blood flow through an artery. Arteries are blood vessels that carry oxygenated blood to body tissues. [ 1 ] [ 2 ] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia . [ 1 ]
Coronary artery disease is the leading cause of death in men and women. [16] This condition is the cause of one third of all deaths, which is especially worse in areas with lower socioeconomic status. [16] Mortality is nearly five times higher in men than women, but mortality difference narrows with age. [16]
Alternatively, arterial occlusion occurs as a consequence of embolism of blood clots originating from the heart ("cardiogenic" emboli). The most common cause is atrial fibrillation, which causes a blood stasis within the atria with easy thrombus formation, but blood clots can develop inside the heart for other reasons too as infective endocarditis.
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
Coronary artery disease is the leading cause of death for both males and females and accounts for approximately 600,000 deaths in the United States every year. [139] According to present trends in the United States, half of healthy 40-year-old males will develop CAD in the future, and one in three healthy 40-year-old females. [ 140 ]
Systemic embolism of venous origin can occur in patients with an atrial or ventricular septal defect, or an arteriovenous connection in the lung, through which an embolus may pass into the arterial system. Such an event is termed a paradoxical embolism. When this affects the blood vessels of the brain it can cause stroke. [6]
Vascular disease is a subgroup of cardiovascular disease. Disorders in this vast network of blood and lymph vessels can cause a range of health problems that can sometimes become severe, and fatal. [3] Coronary heart disease for example, is the leading cause of death for men and women in the United States. [5]
Arterial thromboembolism (ATE) is a less common but more severe form of thromboembolism, which can affect various organs, such as the brain, heart, kidneys, limbs, and mesentery. ATE can cause life-threatening conditions, such as stroke, myocardial infarction, acute kidney injury, limb ischemia, and mesenteric ischemia.
