CCC Flashcards
Causes of new LBBB
Always pathological- treat as STEMI
myocardial infarction
diagnosing a myocardial infarction for patients with existing LBBB is difficult
rhe Sgarbossa criteria can help with this - please see the link for more details
hypertension
aortic stenosis
cardiomyopathy
rare: idiopathic fibrosis, digoxin toxicity, hyperkalaemia
How to define first degree heart block (criteria)
PR interval >200ms
It is usually asymptomatic and doesn’t require treatment
What kind of drug is clopidogrel
Antiplatelet
Primary or secondary (?) prevention of cardiac events
Hypertension with hypokalaemia and hypernatraemia 3 differentials
Primary hyperaldosteronism is the most common (often asymptomatic and no signs on PE)
Plasma renin:aldosterone and low- dexamethasone suppression test to figure out between Cushing and renal artery stenosis
NB that primary hyperaldosteronism may not present with hypokalaemia and is most commonly caused by idiopathic bilateral adrenal hyperplasia causing an adenoma that secretes aldosterone
Which medication commonly causes low magnesium
PPIs
What kind of drug is indapamide
thiazide-like diuretic.
Added when ACE- I isn’t enough (or CCB)
old man, bone pain, raised ALP only
Pagets disease
Increased bone turnover
What is pulses paradoxus
fall in systolic blood pressure of greater than 10mmHg with inspiration
can be measured using manual blood pressure recordings
Triad of cardiac tamponade (fluid in pericardium)
raised JVP, pulses paradoxus and muffled/quiet heart sounds
What type of drug is losartan
Angiotensin receptor blocker
Used first line in hypertension (either tat or ACE-I)
What typically raises gamma GT levels
Alcohol consumption
Treatment for acute heart failure (acronym
Pour SOD
Pour away fluids (reduce fluids)
Sit up right
Oxygen
Diuretics
What do you give in chronic heart failure as first line treatment (with reduced LV ejection fraction)
Beta blocker and ACE inhibitor
Even if they would normally take CCB for HT give ACE-I
If angina is not controlled with a beta blocker and GTN spray what should you add
Long acting dihydropyridine calcium channel blocker e.g. modified release nifedipine
Not verapamil or diltiazem as these has negative chronotropic effects
New BP of more than 180/120, no other symptoms what do you do
Check for end-organ damage
By doing urgent ECG, urine dip and blood tests
How do you treat a young person presenting with AF for the first time with symptoms but not too bad
Anticoagulants for 3 weeks then cardioversion to sort the rhythm
Don’t cardiovert instantly as there is a risk of atrial thrombosis
Young woman with high BMI presents with bilateral headaches worse on bending over and visual symptoms e.g. optic disk blurring
Idiopathic intracranial hypertension
“Starry sky” appearance on biopsy for raised lymph nodes
Non-Hodgkin’s lymphoma
What do you give someone from black A/ A-C origin if their CCB isn’t enough
Give an ARB over an ACE-I e.g. losartan
3 ECG signs of digoxin toxicity
Down-sloping ST depression (reverse tick)
Flattened/ inverted T waves
Short QT interval
Is FEV1:FVC ratio low or high in obstructive and restrictive illness
In obstructive illness the ratio is low as it is difficult to get air out, but it eventually gets out (probs less than normal)
In restrictive illness the amount that can escape is reduced so ratio is. Normal but FVC will be low
Is anterior or posterior MI more likely to cause LBBB
Anterior (or anteroseptal)
Episodic pruritis after a hot bath, with elevated Hb and platelets and mild splenomegaly
Polycythaemia Vera
Which organism most commonly causes infective exacerbations of COPD
Haemophilus influenzae
