Cardiovascular Flashcards
Definition of typical angina
- Constricting discomfort in the front of the chest, in the neck, shoulder, jaw or arms
- Precipitated by physical exertion
- Relieved by GTN
(Atypical only 2 symptoms)
Treatment of uncomplicated, stable angina?
GTN (symptom relief)
beta-Blocker (or CCB)
Treatment for atrial fibrillation?
beta-Blocker (or CCB)
If CHA2DS2VASc score =>2…anticoagulate
Signs & symptoms of AF?
Irregular pulse obvs! And Breathlessness Palpitations Chest discomfort Syncope or dizziness
Diagnosis of ACS?
Chest/arm or other myocardial ischaemia type pain
ECG changes
Troponin rise
General terms what does STEMI vs NSTEMI mean?
STEMI - complete coronary artery occlusion
NSTEMI - incomplete occlusion
Immediate treatment for ACS?
GTN + Aspirin (+ opoid) in primary care
+ anticoagulants in secondary
Long term treatment after ACS?
ACE inhibitor Beta-blocker Statin Anti-platelet therapy (Aldosterone antagonist if LV dysfunction)
Example of discharge medicines post-ACS?
Clopidogrel (anti-platelet) Ramipril (ACEi) Simvastatin Bisoprolol (beta-blocker) (Eplerenone/Spironolactone)
Example of angiotensin II receptor blocker and when it is used?
Candesartan
Eprosartan
Losartan
Used when ACEi contraindicated or not tolerated
Changes on ECG initially with ACS?
Tenting T waves…followed by ST elevation (and possible T wave inversion)
Other ECG changes of ACS?
New LBBB
Pathological Q waves (hours-days) - MI
Mechanism of action of heparin?
Binds to antithrombin III, which inactivates thrombin and factor Xa
Mechanism of action of eptifibatide/tirofiban
Glycoprotein IIb/IIIa inhibitors, inhibit platelet aggregation (as the drugs bind to glycoprotein receptors)
What is vWF?
von-Willebrand Factor, found in subepithelial matrix of blood vessel, binds to glycoprotein Ib on platelets, activating platelets (upon endothelial injury, which exposes vWF)
Henoch-Schonlein pupura symptoms (and signs)?
Classic triad: Purpura; arthralgia (arthritis); abdo pain
Signs include proteinuria and haematuria
Henoch Schonlein purpura pathophysiology?
Immune complexes of IgA and complement C3 are deposited on veins, arteries, capillaries, therefore a vasculitis essentially
Diagnosis of hypertension?
BP >140/90, and confirmed with ABPM (>135/90)
Or BP>180/110
1st line Treatment for HTN age <55
ACEi (or ARB)
1st line Treatment for HTN age > 55, or black any age?
Ca channel blocker
2nd step treatment for HTN? any age
Add either ACEi or Ca channel blocker (whichever wasn’t added at step 1)
3rd step treatment for HTN? any age
ACEi + Ca blocker
Add thiazide diuretic e.g. indapamide or chlortalidone
4th step treatment for HTN?
ACEi + CCB + thiazide diuretic
Add low dose spironolactone
Collapsing pulse sign of…?
Aortic Regurgitation
