Secondary prevention of stable cardiovascular disease with an indication for an anticoagulant
If an indication for anticoagulant exists (for example atrial fibrillation) it is indicated that anticoagulant monotherapy is given without the addition of antiplatelets
209
Post-acute coronary syndrome/percutaneous coronary intervention drugs
generally patients are given triple therapy (2 antiplatelets + 1 anticoagulant) for 4 weeks-6 months after the event and dual therapy (1 antiplatelet + 1 anticoagulant) to complete 12 months
210
Vte anticoagulant with antiplatelet?
if a patient on antiplatelets develops a VTE they are likely to be prescribed anticoagulants for 3-6 months an ORBIT score should be calculated. Those with a low risk of bleeding may continue antiplatelets. In patients with an intermediate or high risk of bleeding consideration should be given to stopping the antiplatelets

Flecainide or ajmaline challenge to unmask ECG pattern
Brugada Syndrome
279
Mutation in RYR2 receptor in sarcoplasmic reticulum
Catecholaminergic Polymorphic VT (CPVT)

Reverse Nike tick"
down-sloping ST + T inversion Digoxin Toxicity
281
Pulmonary stenosis Associated conditions:
Carcinoid cancer (flushing, diarrhoea, weight loss)
282
Directed therapy Infective endocarditis
Staphylococci (native): Flucloxacillin Staphylococci (prosthetic): Flucloxacillin + gentamicin + rifampicin Streptococci: Benzylpenicillin first-line
283
Negative AVT response
iloprost, bosentan, sildenafil.
284
Positive AVT response
CCBs - Nifedipine.
285
Pulmonary hypertension Definition: Investigations
echocardiogram, right heart catheterisation is diagnostic PAP > 25mmHg at rest → RHF
286
Pulmonary HypertensionCauses & Classification (WHO Groups)
Group 1: Idiopathic / familial, HIV, persistent PH of the newborn Group 2: Secondary to left-sided heart disease Group 3: Secondary to lung disease – COPD, ILD, OSA Group 4: Chronic thromboembolic PH – e.g. recurrent PE Group 5: Miscellaneous – sarcoidosis, systemic disorders, tumours
287
Endothelin receptor antagonist
bosentan, ambrisentan
288
ESM with fixed splitting of S2
Asd
289
pericardial knock
an early diastolic sound caused by sudden cessation of ventricular filling as the rigid pericardium limits expansion
290
Why is therean ejection systolicmurmur in hocm
Dueto lvoot
291
In Constrictive pericarditis there is pericardial knock, whereas in Viral pericarditis
there is Pericardial rub- grating sound in LSB
292
Syncope following stimuli/stress
LQT2
293
paradoxical embolism
right-to-left shunt, most commonly a patent foramen ovale (PFO)
294
ELECTRICAL ATERANSPULSUS ALTERANS
in cardiac Tamponade its ELECTRICAL ATERANS shortening of QRS amplitude on ECG . Here it is PULSUS ALTERANS - The failing left ventricle can’t keep a steady output it alternates between strong and weak beats because of fatigue + calcium imbalance.
295
According to NICE, the definitive treatment for flutter is
radiofrequency catheter ablation of the cavotricuspid isthmus.

Management of UA/NSTEMI
(1) Antiplatelet - 1st Line: Aspirin 300mg. (2) Antithrombin - 1st Line: Fondaparinux, Alt: UFH if significant renal impairment or high bleeding risk. (3) Risk determines further management (i.e. decision for early CA +/- PCI)

Successful reperfusion after thrombolysis is defined as ≥50%
resolution of ST elevation at 60–90 minutes.
