Cardiology Flashcards
Most Specific ECG Finding in Acute Pericarditis
PR Depression
2 main complications of PCI
- Restenosis (5-20%)
- Stent Thrombosis (1-2%)
Restenosis presenting complaint
Recurrence of Angina
Stent Thrombosis presenting complaint
Acute MI
What are Drug-eluting stents
Stent coated with paclitaxel or rapamycin which inhibit local tissue growth
Complications of Drug-eluting stents
Reduces restenosis rates, but stent thrombosis rates are increased
NICE Guidelines for Amiodarone
To be given 4 weeks prior to Electrical cardioversion if high risk of failure
AF onset less than 48 hours anticoagulation rule
patient should be heparinised
Cardioversion for AF onset less than 48 hours
- Electrical
- Pharmacological
AF onset more than 48 hours anticoagulation rule
3 week anticoagulation prior to cardioversion
Rheumatic Heart Disease Histological Finding
Aschoff Bodies
Most Common Complication Post MI
Ventricular fibrillation
Catecholaminergic Polymorphic Ventricular Tachycardia cause
Defect in the ryanodine receptor (RYR2)
Catecholaminergic Polymorphic Ventricular Tachycardia feature
Symptoms generally develop before the age of 20 years
Management of Catecholaminergic Polymorphic Ventricular Tachycardia
- Beta-blockers
- Implantable cardioverter-defibrillator (ICD)
Jervell and Lange-Nielsen syndrome C/F
- congenital long QT syndromes
- sensorineural deafness
Poor Prognosis in Infective Endocarditis
- Staphylococcus Infection
- Prosthetic Valve
- Culture Negative Endocarditis
- Low complement levels
Better Prognosis in Infective Endocarditis
- Streptococcal Infection
DEAR mnemonic for Adenosine
- Dipyridamole Enhances effect
- Aminophylline Reduces effect
- Lignocaine also Enhance

Hypertension Step 1 DOC for patients < 55-years-old or with diabetes mellitus
Angiotensin receptor blocker (ACE-i or ARB)
Hypertension Step 1 DOC for patients >= 55-years-old or of black African origin:
Calcium channel
blocker
Hypertension Step 2 treatment
if already taking an ACE-i or ARB add a Calcium channel blocker or a thiazide-like Diuretic
Hypertension Step 4 treatment
if potassium < 4.5 mmol/l add low-dose spironolactone
if potassium > 4.5 mmol/l add an alpha- or beta-blocker
