- cardiovascular system malfunctions: heart disease
- coronary arteries become narrowed or clogged
- cant supply enough blood to the heart
- not enough oxygen carrying blood gets to the heart
- heart responds with pain called angina
- angina- pain usually felt in the chest or left arm/ shoulder
- when blood supply is completely cut off
- = heart attack
- part of the heart begins to die
- some parts may be permanently damaged
- heart responds with pain called angina
- symptoms
- shortness of breath
- heaviness
- tigntness
- pain
- burning
- pressure
- causes
- heredity
- genes identified to cause chd
- high cholestrol
- LDL bad cholestrol
- fats on the walls of arteries
- tobacco abuse
- reduce oxygen supply to blood vessels
- obesity
- increases likelihood of high blood pressure/ cholestrol
- high blood pressure
- hypertension, strain on the vessel walls
- stress
- leads to constriction of blood vessels
- heredity
- diagnostic techniques
- angiogram
- look inside coronary arteries
- see if they are narrowed
- helps decide if treatment is needed
- will be under local anaesthetic
- flexible tube passed through the artery
- dye passed through blood vessels
- show up narrowed areas
- dye passed through blood vessels
- flexible tube passed through the artery
- look inside coronary arteries
- blood pressure monitoring
- if too high vessels can be damaged
- if too low can be dangerous for vital organs
- measured with sphygmomanometer
- ECG traces
- electrical activity within the heart detected
- attach electrodes to the limbs
- shows info about heart muscle
- attach electrodes to the limbs
- electrical activity within the heart detected
- angiogram
- effects
- angina
- difficulty with everyday tasks
- low self esteem
- changes to work
- changes to social life
- social isolation
- angina
- treatment
- ace inhibitors
- used to treat high blood pressure
- block activity of angiotensin II
- narrows blood vessels
- stops heart working so hard
- improves blood flow
- beta blockers
- prevent angina
- treat high blood pressure
- slows down heart beat
- heart bypass surgery
- blood vessel inserted between aorta
- allows blood to get around narrowed arteries
- regular check ups after
- lifestyle changes
- ace inhibitors
- coronary arteries become narrowed or clogged
