Medicine workbook & passmedicine info
8 potential features of severe aortic stenosis
narrow pulse pressure
slow rising pulse
delayed ESM
soft/absent S2
S4
thrill
duration of murmur
left ventricular hypertrophy or failure
3 main symptoms of aortic valve disease
Chest pain, dysponea, Syncope
7 Features of mitral stenosis
mid-late diastolic murmur (best heard in expiration)
loud S1,opening snap
low volume pulse
malar flush
atrial fibrillation
What would you suspect if a patient has persistent ST elevation following recent MI and no chest pain?
Left ventricular aneurysm (ischaemic damage sustained may weaken myocardium -> persistent ST elevation and left ventricular failure. Thrombus may form within the aneurysm thus anticoagulate these patients)
Where is BNP produced?
Left ventricular myocardium (in response to strain)
What can cause raised BNP?
Heart failure
and any cause of left ventricular dysfunction
such as MI or valvular disease
CKD (due to reduced excretion)
What are the effects of BNP?
vasodilator
diuretic and natriuretic
suppresses both sympathetic tone and the renin-angiotensin-aldosterone system
What type of murmur do you get in mitral stenosis?
Mid-late diastolic, ‘rumbling’ in character (like Austin-Flint murmur of severe aortic regurgitation)
3 causes of an ejection systolic murmur
aortic stenosis
pulmonary stenosis, hypertrophic obstructive cardiomyopathy
atrial septal defect, tetralogy of Fallot
What type of murmur do you get in aortic regurgitation?
Early diastolic murmur, high-pitched and ‘blowing’ in character
(same as Graham-Steel murmur of pulmonary regurgitation)
What type of murmur is typical for mitral regurgitation?
Holosystolic/Pansystolic (starts at S1 ends at S2) murmur, high-pitched and ‘blowing’ in character (tricuspid is same)
