Overview

Vascular disease is a class of diseases of the blood vessels – the arteries and veins of the circulatory system of the body. It is a subgroup of cardiovascular disease. Disorders in this vast network of blood vessels, can cause a range of health problems which can be severe or prove fatal.[1]

Associated medical conditions

Types

There are several types of vascular disease, (which is a subgroup of cardiovascular disease) among them are:[2]

Mechanism

Vascular disease is a pathological state of large and medium muscular arteries and is triggered by endothelial cell dysfunction. [8]Because of factors like pathogens, oxidized LDL particles and other inflammatory stimuli endothelial cells become active. [9]The process causes thickening of the vessel wall, forming a plaque that consists of proliferating smooth muscle cells, macrophages and lymphocytes.[10] [11]The plaque results in a restricted blood flow which will decrease the amount of oxygen and nutrients that reach certain organs,[12] the plaque might rupture causing the formation of clots.

Diagnosis

It can be difficult to make a Vascular disease diagnosis since there are a variety of symptoms that a person can have, also family history and a physical examination are important. The physical exam may be different depending on the type of vascular disease. In the case of a peripheral vascular disease the physical exam consists in checking the blood flow in the legs.[13][14]

Treatment

Treatment varies with the each type of Vascular disease, in the case of Renal artery disease information from a meta-analysis indicated that balloon angioplasty results in improvement of diastolic blood pressure and a reduction in antihypertensive drug requirements.[15] In the case of Peripheral artery disease preventing complications is important, without treatment sores or gangrene (tissue death) may occur. Among the treatments are: [16]

  • Quit smoking
  • Lower cholesterol
  • Lower blood pressure
  • Lower blood glucose
  • Physical activity
