Cardiology Flashcards
Patients with heart failure are most at risk of which two types of infection?
- Chest infections
2. Ulcerated cellulitis of the lower limbs
What 4 drugs/ drug classes have an evidence base for improving mortality in patients with chronic heart failure?
- ACE inhibitors
- Spironolactone
- Beta-blockers
- Hydralazine with nitrates
What is the first line treatment for all patients with chronic heart failure?
ACE inhibitor + a Beta-blocker
When is sacubitril- valsartan indicated in the treatment of chronic heart failure?
In patients with a reduced ejection fraction who are symptomatic on an ACE inhibitor
Name 3 beta-blockers licensed in the UK for the treatment of heart failure
- Bisoprolol
- Carvedilol
- Nebivolol
Though most patients with heart failure only require a one off pneumococcal vaccination, give 3 concurrent conditions that would require the patient to receive booster vaccinations every 5 years
- Asplenia
- Splenic dysfunction
- Chronic kidney disease
Simply contrast the pathophysiology of systolic and diastolic heart failure respectively
Systolic - Impaired contraction of the LV
Diastolic - Impaired relaxation of the LV
A productive cough in heart failure is associated with what type of sputum?
Frothy white/pink sputum
What are the 5 classical presenting features of patients with chronic heart failure?
- SOB that is worse on exertion
- Cough
- Orthopnoea
- PND
- Peripheral oedema
What are the 4 main categories of pathology that can lead to heart failure?
- Ischaemic heart disease
- Valvular heart disease e.g. aortic stenosis
- Hypertension
- Arrhythmias
According to NICE guidelines what BNP level requires an urgent specialist referral for patients with heart failure?
BNP > 2000
Name a patient cohort for which ACE inhibitors should NOT be prescribed for the treatment of heart failure
Patients with established valvular heart disease
Pulmonary hypertension is most commonly associated with what abnormal heart sound?
Loud S2
What pathologies causes a soft S2 heart sound?
Aortic stenosis
Name 4 potential causes of a widely split S2 heart sound
- RBBB
- Deep inspiration
- Pulmonary stenosis
- Severe mitral regurgitation
What is the normal PR interval range?
0.12 -0.21 seconds
Suggest 4 potential causes of sinus bradycardia
- Athletic physiology
- Acute MI
- Sick sinus syndrome
- Beta - blockers
Name 3 non-cardiac disorders which can lead to sinus bradycardia

- Raised ICP
What is the most common form of cardiomyopathy?
Dilated cardiomyopathy
Suggest 4 infections that can lead to myocarditis
- Coxsackie B
- HIV
- Diphtheria
- Chagas disease
Name 2 substances of abuse that can potentially cause dilated cardiomyopathy
- Alcohol
2. Cocaine
Name a genetic syndrome associated with increased incidence of dilated cardiomyopathy
Duchenne muscular dystrophy
Name 2 infiltrative diseases that can potentially cause dilated cardiomyopathy
- Haemochromatosis
2. Sarcoidosis
Why can a systolic murmur sometimes develop in cases of dilated cardiomyopathy?
Stretching of the valves may lead to mitral and tricuspid regurgitation
