Common Cardiac Conditions Flashcards
Which leads on the ECG relate to the coronary arteries?
Lateral leads: I, aVL, V5, V6 - left circumflex
Anterior leads: v1-v4 - LAD
Inferior leads: II, III, aVF - Right coronary
What are some common modifiable cardiovascular risk factors?
- Smoking
- High cholesterol
- HTN
- Obesity
What are some common non-modifiable cardiovascular risk factors?
- Age
- Family Hx of heart/ cardiovascular disease
- Gender (more common in men< 50 then equals out)
- Race (African american greatest risk )
What is the immediate management of a patient with a STEMI?
- IV acess
- Pain relief (morphine)
- Anti-emetic e.g. metoclopramide
- Oxygen
- Aspirin 300mg
- Digoxin (if systolic BP ok)
- Clopidogrel loading dose (600mg)
- PPCI
What does cardiac rehabilitation entail?
Medically supervised exercise programme for people who have had cardiac intervention
Mix of exercise and education sessions
What are some of the possible complications of acute MI?
- Arrythmia
- Hypotension
- Ventricular septal rupture
- Left ventruicular free wall rupture
- Left ventriculat aneurysm formation
What is the long term medication that should be initiated after a patient has an MI?
Dual Antiplatelet therapy Clopidogrel 75mg OD / Prasugrel 10mg OD
Blood pressure control ACEi e.g. Ramipril 2.5mg OD or ARB e.g. Losartan 25mg OF
Beta blocker e.g. bisoprolol 1.25 mg OD
Cholesterol lowering agent - Statin e.g. atorvastatin 80mg OD
What features in a patients history would suggest heart failure?
- Increasing breathlessness and reduced exercise tolerance
- Oedema
- Orthopnoea (breathless lying flat)
- PND (paroxysmal nocturnal dyspnoea)- shortness of breath when asleep
- Nocturnal cough
- Wheeze
- Anorexia
What are some of the common causes of heart failure?
- Ischemic heart disease (most common)
- AF
- Valvular heart disease e.g. rheumatic fever
- Hypertension
- Cardiomyopathy
- Previous cancer/ chemotherapy
- Chronic lung disease
- HIV
Why do patients with HF develop ankle oedema?
Cardiac output is low so kidneys are poorly perfused. This activates RAAS which causes Na+ and H2O retention leading to fluid overload
The RV does not pump efficiently causing reduced venous return so fluid remains in peripheries
What type of oedema are you more likely to get in left vs right sided HF?
Left: pulmonary oedema
Right: peripheral oedema
How do you manage an acute presentation of HF?
- Sit patient upright
- Give high flow O2 if SpO2 is low
- Get IV access and monitor ECG
- Diamorphine 1.25-5 mg IV - slowly
- Furosemide 40-80mg IV - slowly
- GTN spray if chest pain
How do you manage a chronic presentation of HF?
-
Diuretics
- Furosemide (IV) / Bumetanide (oral)
- ACEi if patient hypertensive
- ARB
- Sacubotril / Valsartan (Angiotensin Receptor Neprilysin inhibitor) only if NYHA II-IV
-
Beta blockers - start low go slow.
- only if HR >60 and SBP >100mmHg
- Vasodilators
- Ivabradine - later add on must be in sinus rhythm
- Nitrates - reduce preload
How do you manage a patient with acute SVT?
- Try Valsalva manouvre if haemodynamically stable in unsuccessful:
- Adenosine 6mg stat (can increase to 12mg if unsuccessful)
- Start heparin or IV flecainide
What is the indication for electrical DC cardioversion?
If the patient has AF + adverse signs:
- shock
- MI (chest pain/ ECG change
- syncope
- HF
What drugs are used in the long term management of permanent AF?
- Beta blocker 1st line
- Digoxin if this fails
- Anticoagulation with DOAC
