List the four cardiovascular diseases caused by tobacco use:

Here is what I found...

Atherosclerosis, in which arteries narrow and become less flexible,

occurs when fat, cholesterol, and other substances in the blood form

plaque that builds up in the walls of arteries. The opening inside the

arteries narrows as plaque builds up, and blood can no longer flow

properly to various parts of the body. Smoking increases the formation

of plaque in blood vessels.

Coronary Heart Disease occurs when arteries that carry blood to the

heart muscle are narrowed by plaque or blocked by clots. Chemicals in

cigarette smoke cause the blood to thicken and form clots inside veins and

arteries. Blockage from a clot can lead to a heart attack and sudden death.

Stroke is a loss of brain function caused when blood flow within the

brain is interrupted. Strokes can cause permanent brain damage and

death. Smoking increases the risk for strokes. Deaths from strokes are

more likely among smokers than among former smokers or people who

have never smoked.

Peripheral Arterial Disease (PAD) and peripheral vascular disease occur

when blood vessels become narrower and the flow of blood to arms, legs,

hands and feet is reduced. Cells and tissue are deprived of needed oxygen

when blood flow is reduced. In extreme cases, an infected limb must be

removed. Smoking is the most common preventable cause of PAD.

Abdominal Aortic Aneurysm is a bulge or weakened area that occurs

in the portion of the aorta that is in the abdomen. The aorta is the main

artery that carries oxygen-rich blood throughout the body. Smoking is a

known cause of early damage to the abdominal aorta, which can lead to

an aneurysm. A ruptured abdominal aortic aneurysm is life-threatening;

almost all deaths from abdominal aortic aneurysms are caused by

smoking. Women smokers have a higher risk of dying from an aortic

aneurysm than men who smoke. Autopsies have shown early narrowing

of the abdominal aorta in young adults who smoked as adolescents.

Here are five diseases instead of four. I apologize but I found nothing that only had four.
