Q

What are the main X2 types of HF, and what causes them?

A

Reduced Ejection Fraction HF- this is when the heart does not contractt forceful enough during systole

Preserved Ejection Fraction HF:
The left ventricle is too stiff, so less blood fills overall resulting in reduced ejection fraction

-base change in an exon nonsense mutation forming a premature stop codon
26
What is the genetic mutation in sickle cell syndrome?
Genetic - point mutation in codon 6 of the β globin gene that substitutes glutamine to valine producing βS

Hypertrophic Cardiomyopathy? a) What is the 1st line management b) what is the definitive management
Hypertrophic cardiomyopathy 1st line- beta blockers definitive- ICD
28
What function is mainly impaired in hypertrophic cardiomyopathy?
reduced diastolic function
29
What is Frank Sterling Law?
Frank Sterling Law: * relationship between stroke volume and end diastolic volume
30
What does J waves indicate?
-eat JELLYBABIES when hypothermic -hypothermia
31
What medications are known to reduce the mortality rates of HF? (*must know! in MLA exam last year)
(beta blockers)-carvedilol and bisoprolol
32
What are the X4 main types of Syncope?
-reflex -orthostatic hypotension -carotid sinus reflex -cardiac syncope
33
What is reflex syncope?
reflex- brief loss of consicousness due to a neurologically induced drop in blood pressure
34
What is Carotid Sinus Reflex?
activation of the baro-recpetors in the neck due to exertion of pressure- e.g tight collars or shaving
35
What is the main triad of symptoms in cor pulmonale?
pulmonary oedema elevated JVP hepatosplenomegaly- inc pressure on the hepatic vein
36
What vessel layer is damaged in: - aortic dissection - AAA
What vessel layer is damaged in: - aortic dissection- tunica intima - AAA- tunica media
37
what condition is associated with: Different blood pressure measurements in each arm, and tearing chest pain radiating to the back is associated with?
Aortic Dissection
38
What are the X2 main types of aortic dissection and associated symptom? b) what part of the aorta is damaged?
- Aortic Dissection type A (*More common- ascending aorta- common ascend in life- **chest pain** - Aortic Dissection type B (*less common in descending aorta)- back pain
39
What is the 'diagnostic' investigation for Aortic Dissection?
Diagnostic Investigation = CT angiography (*false lumen is the positive finding)
40

- spontaneous rupture of the full layers of oesophagus due to repeated episodes of vomiting - associated with alcoholics - bloody vomiting - more severe than mallory weiss tear, malory weiss is NOT Painful only superficial tea
42
What is the main area damaged in Boerhaaves Syndrome? (*Must know- very painful full rupture)
* usually DISTAL aorta
43
What is the diagnostic investigation for boerhaaves Syndrome?
* Diagnostic Investigation > CT contrast Swallow (*as associated with vomiting and rupture of oesophagus)

51
Electrical alternans is associated with?
Cardiac Tamponade
52
What is the most common heart valve effected in infective endocarditis? b) most common valve effected in iV drug users?
most common- mitral valve (m-most common) IV drug user- tricuspid
