Cardiovascular disease

Atherosclerosis, arteriosclerosis, angina, hypertension, myocardial infarction (heart attack) and stroke

Atherosclerosis

Formation and deposition of plaque on the inner walls of arteries and is the early stage of arteriosclerosis

Atherosclerosis at the early stage

Occurs when calcium settles on plaque

Causes of arteriosclerosis

Occurs when calcium settles on plaque causing arteries to harden and lose their elasticity.

Hypertension

Causes fine arteries to rupture and patients can have a stroke if this happens in the brain

Stroke

Caused by blood clots (thrombus) that block blood flow to the brain.

Angina

Severe chest pain due to lack of oxygen supply to the heart muscle

Myocardial infarction.

A heart attack is when an artery is completely clogged and causes no supply of oxygen to the heart muscle.

Plaque

Formed from cholesterol, lipids, dead muscle tissue and clotted platelets

Factors contributes to cardiovascular disease

Smoking habits, hypertension, obesity, high cholesterol levels, inactive lifestyle and diabetes
