Reasons for Causes

PAD often arises from atherosclerosis, a condition where plaque builds up in the arteries, causing them to harden and narrow. , 2 , This process can be accelerated by factors like smoking, high blood pressure, high cholesterol, and diabetes. emphasizes the significant impact of environmental factors on PAD, including air pollution and heavy metals, which can contribute to atherosclerosis and inflammation.

Common Causes

Atherosclerosis

Atherosclerosis, the buildup of plaque in the arteries, is the most prevalent cause of PAD. , 2 , This hardening and narrowing of the arteries can be triggered by factors like smoking, high blood pressure, high cholesterol, and diabetes.

Environmental Factors

Thrombosis

Thrombosis, the formation of blood clots in arteries, can lead to PAD. These clots can arise due to advanced atherosclerosis or heart conditions. describes thrombosis as a major cause of acute limb ischemia (ALI), a severe form of PAD.

Genetics

Genetics can influence the risk of developing PAD. 2 suggests a possible link between polyvascular disease and cancer incidence in patients with coronary artery disease, indicating that genetic factors might play a role in the progression of atherosclerosis.

Aging
