3.2 Common Cardiac and Circulatory Issues, Clinical Manifestations and Treatments

Coronary Heart Disease

chronic condition when blockages of the coronary arteries happen over time

Myocardial Infarction

a complete and sudden obstruction of blood flow to a coronary artery causing the death of an area of tissue due to interrupted blood supply, commonly known as a heart attack

Example of Vascular occlusive disease

Peripheral Arterial Disease (PAD)

Peripheral Arterial Disease (PAD)

Peripheral Arterial Disease is caused by fatty plaque build up in arteries narrowing them and reducing blood flow affecting the contractility of the heart

Valve Issues

Stenosis and Regurgitation

Stenosis

valves have become too stiff and do not properly open, causing resistance to blood flow in the cardiovascular system

Regurgitation

valves have become damaged and do not close properly allowing backflow of blood, limiting efficiency of system and potentially disrupting normal blood flow
