chapter 8: cardio Flashcards
Osler’s nodes
Janeway lesions
Splinter haemorrhages
associated with:
infective endocarditis.
malar flush associated with
mitral valve stenosis
Why does oedema occur in heart failure?
- increased venous pressure
- increases capillary hydrostatic pressure
- greater extravasation of fluid than returning of fluid
- oedema will result
how do ACE inhibitors work?
- block formation of angiotensin 2
- thus dilation of efferent arteriole
- increase in renal blood flow
- decrease in GFR
signs of infective endocarditis
- splinter haemorrhages
- splenomegaly
- murmur
- fever
- janeway’s lesions
- osler nodes
what resp abnormality might be seen in patients with DVT?
- respiratory alkalosis
- due to hyperventilation causing lowered arterial carbon dioxide
name of pain that occurs then during work that makes you have to stop inbetween
intermittent claudication
why does aortic stenosis result in a slow rising pulse?
- rate of injection of blood into aorta is decreased
- as a result of poorly functioning ventricle
- therefore duration of ejection is prolonged
- amplitude of pulse is diminished
angina results from
- increased oxygen requirement
- due to hypertrophic myocardium
babies with patent ductus arteriousus will have what murmur sound
- machinery’ like murmur
58 y/o male:
- shortness of breath, chest pain and dizziness
- slow rising pulse
- soft S2 heart sound
- crescendo decrescendo murmur in 2nd ICS
what cardiac abnormality associated with this condition?
aortic stenosis
65 y/o female, shortness of breath, esp when lying down. swollen ankles. irregular pulse and holosystolic murmur at apex of heart radiating to axilla.
which cardiac abnormality will cause this presentation
mitral regurgitation
truncus arteriosus gives rise to
ascending aorta
pulmonary trunk
bulbus cordis gives rise to
ventricles
why does ejection systolic murmur occur
due to turbulence that occurs as blood flows across the stenotic valve
