DELTA Flashcards
What is the normal E/e’ value?
<8
What is the appearance of abnormal myocardium on MRI + Gadolinium?
normal = black
scar = white
Causes of:
- subendocardial scar
- transmural scar
- mid wall scar
- subepicardial scar
- endocardial
MI
MI
non-ischaemic with remodelling
myocarditis
amyloidosis
Treatment approach for HFpEF
SGLT2i - not available on PBS to non-diabetics
Diuretics to maintain normal filling pressures
ARBs
Salt restriction
Exercise training
Manage comorbidities
EMPEROR-preserved study
HFpEF patients given Empa or placebo
Non-diabetic + diabetic
reduced 1’ end point (mainly driven by HF admissions)
b-blockers; most cardioselective
metoprolol and bisoprolol
nebivolol is intermediate
carvedilol also action on b2, a1, vasodilator effects also
Ivabradine
- indications
must be in sinus rhythm, maximal b-blocker therapy
reduction in CV death / hospitalisations in those with
target <77
What is the effect of neprilysin
breaks down BNP
How long should ACEi / ARB be stopped prior to commencement of ARB/ARNI?
36 hours
risk of angioedema
Chemo and cardiotoxicity / HF
frequent monitoring
give ACEi and B-blockers
consider dose reduction
Hypertrophic CM
- inheritance pattern
autosomal dominant
variable penetrance
age related disease expression
Hypertrophic CM
- effects
“Myocyte disarray”
asymmetric septal, mid-ventricular, apical and concentric patterns
can occur with or without LVOT obstruction
HCM
- presentation
asymptomatic screening
palpitations and syncope
sudden death in young - most common cause
endocarditis
dyspnoea and angina
HCM
- risk factors for SCD
FHx premature SCD
Recurrent syncope
Non-sustained VT
Severe LVH (septum >2.5-3cm)
Severe obstruction
Abnormal exercise BP response
myocardial fibrosis on MRI
Specific genotypes
Amyloidosis
- configuration of deposited protein
- staining pattern
- types
antiparallel beta-pleated sheets
congo red stain - apple-green
AL amyloid (primary) e.g multiple myeloma
AA amyloid (secondary) e.g. RA, IBD, chronic infection
ATTR amyloid - wt or inherited
Other: dialysis, heritable, age related, organ specific
