Cardiovascular Flashcards
What is the most appropriate treatment of hypertension during pregnancy?
1st Line: Labetolol - if starting treatment or if changing (pt already on ACE/ARB etc for prev htn )
- Nifedipine (CC) if labetolol not suitable ie patient is asthmatic (unlicensed use)
- Consider methyldopa 3rd line
ACE/ARBs/thiazide like diuretics not recommended during pregnancy
Clinical features of mitral stenosis
SOB, fatigue, malar flush
Mid-late diastolic murmur
ECG changes: bifid P waves (P mitrale) - sign of atrial enlargement
Side Effects of statins
- myopathy: includes myalgia, myositis, rhabdomyolysis and asymptomatic raised creatine kinase
- Liver impairment- check LFTs at baseline, 3 months and 12 months. Stop if 3x upper limit normal
- some evidence that statins may increase the risk of intracerebral haemorrhage in patients who’ve previously had a haemorrhagic stroke- avoid in these pts
Statin Dosing primary vs secondary?
atorvastatin 20mg for primary prevention
- (increase the dose if non-HDL has not reduced for >= 40)
atorvastatin 80mg for secondary prevention
Contraidications for statins
- macrolides (erythromycin/clarithromycin)
- pregnancy
What drugs should be given on discharge post PCI?
a statin, an ACE inhibitor, a beta-blocker and dual antiplatelet therapy after PCI to reduce the likelihood of future coronary events
What is the acceptable rise in creatinine and potassium from baseline after starting ACEi?
30% rise in creatinine, K+ up to 5.5mmol/l
- check U&E 2 weeks after starting and 2 weeks after each dose change. Once maintenance dose established check U&E at 1, 3 and 6 months
What are the features of aortic regurgitation?
- early diastolic murmur
- collapsing pulse
- wide pulse pressure
- Quincke’s sign (nailbed pulsation)
- De Musset’s sign (head bobbing)
- mid-diastolic Austin-Flint murmur in severe AR - due to partial closure of the anterior mitral valve cusps caused by the regurgitation streams
What are the causes of AR: acute vs chronic
Chronic:
- rheumatic fever
- bicuspid aortic valve
- connective tissue disorders (SLE, RA)
- calcified valve disease
- Marfans/EDS
- HTN
- Syphilis
Acute:
- infective endocarditis
- Aortic root dissection
Management of chronic refduced or mildly reduced EF heart failure
ABAL
- A- ACEi
- B- Beta blockers
- A- Aldosterone antagonist (MRA) ie spiro
- L- Loop diuretics ie furosemide when overload present
What % ejection fraction = reduced, mildly reduce or preserved EF
<40% = HFrEF
41-49% =HFmrEF
>50%= HF-PEF
Drugs that worsens HF?
NSAIDs, CCBs, BBs
When to refer HF pts based on BNP
- If NT-pro-BNP >2000 ng/L (236 pmol/L), refer urgently for specialist assessment and echo to be seen within 2 weeks.
- If NT-pro-BNP between 400–2000 ng/L (47–236 pmol/L), refer for specialist assessment and echoto be seen within 6 weeks.
- If NT-pro-BNP <400 ng/L (47 pmol/L), be aware that a diagnosis of heart failure is less likely. Consider discussion with a physician with subspecialty training in heart failure if a clinical suspicion of heart failure persists.
What are the clinical features of pericarditis?
chest pain: may be pleuritic. Is often relieved by sitting forwards
other symptoms include a non-productive cough, dyspnoea and flu-like symptoms pericardial rub
What ECG changes are seen in pericarditis?
- Global changes
- PR depression
- Saddle/concave ST elevation
