Cardiovascular Flashcards
Why does a heart attack cause pain?
the resulting ischaemia is painful
a completely irregular heartbeat is often what diagnosis?
atrial fibrillation
what is angina?
reversible, temporary coronary ischemia due to narrowing of vessels - the pain occurs during stress
How does angina differ from a heart attack?
usually with an MI they will tell you that they weren’t exerting themselves at all when it occurred.
what sort of rhythmic patters can you observe?
irregular-regularly
regular
or completely irregular
how does cocaine use influence coronary health?
cocaine use greatly accelerates plaque formation and deposition in the coronary arteries
how does oestrogen effect coronary health?
oestrogen is a protector of the coronary arteries - hormone replacement therapy does the same after menopause
what is the widow maker vessel of the heart?
left anterior descending - lesions in this vessel are particularly dangerous
how might caffeine effect heart function?
Can cause an increased heart beat- potentially effect proper profusion to the brain; cause fainting
what is it called when a patient wakes up in the night gasping for air?
Paroxysmal Noctural Dyspnoea - where the liquid in their lungs distributes throughout the lungs when they lie flat - they are literally drowning in their own fluids and wake up gasping for air - this is made better if you sleep sitting up/standing
how do we measure the severity of paroxysmal nocturnal dyspnoea?
“Orthopnoea” - which is the number of pillows you sleep proped up with
What is a TIA?
transcient ischemic attack - these are mini strokes where there are small blood clots in the carotid arteries leading to a temporary ischaemia of the brain (like angina of the brain)
how does heart failure effect your weight?
extravascular water in your tissues leads to weight gain (you drink more to replace what is lost in extracellular space) - this is a way we measure your cardiac failure and ensure you’re getting the correct amount of diuretics
why do you ask patients with an MI - “ what were you thinking when this occurred?”
b/c some patients have “impending demise” where they honestly feel like “this is it” more so than “ I worry that I could die from this”
pressure in the chest is associated with cardiac - but stabbing like pain is commonly what…?
respiratory
