Among patients with acute coronary syndromes (ACS) undergoing coronary angiography, radial access appears to be more superior compared to femoral access in terms of the following outcome except?

A 70 year old man presents with severe crushing chest pain radiatingto his left arm.He has a background history of hypertension, hyperlipidemia, type 2 diabetes and is a smoker. ECG is obtained on presentation and this shows 3-4mm ST elevation over lead V1-V6,I and aVL with reciprocal ST depression over II,II and aVF.

Where is the likely site of lesion responsible for the changes seen on his ECG?

Which part of the jugular venous waveform is associated with the fall in atrial pressure during ventricular systole?

A 45 year old man previously fit and well presents to the emergency department with a one hour history of retrosternal chest pain. His ECG shows 3mm ST elevation over lead V2 and V3. On examination, he is alert but appears in distress with pain. P: 80, BP: 120/80, RR: 20, Sats: 96% on air. Heart sounds are dual. No murmur. Chest was clear on auscultation. No pitting edema.

Which of the following is not a contraindication to percutaneous mitral balloon valvotomy for moderate to severe mitral stenosis?

Acute myocardial infarction can be classified on the basis of presence or absence of ST segment elevation on the ECG and is further classified into 6 types.

When an AMI is due to infarction related to a percutaneous coronary intervention, which Type of MI is this?

What type of murmur is heard in aortic sclerosis?

A 50 year old man from Invercargill presents to the Emergency Department with chest pain. He is subsequently diagnosed with an anterior STEMI. Following stabilization with thrombolysis and antiplatelet medications, he is transferred to a tertiary hospital for an angiogram. His angiogram showed an 80% stenosis in the left main coronary artery with SYNTAX score of 5 (ie: low anatomic complexity). He is offered a coronary artery bypass graft but refused to have this done.

Which of the following intervention is likely to provide a similar outcome in terms of mortality and risk of future myocardial infarction in 3 years time?

The GRACE Score is a prospectively studied scoring system that risk stratifies patients with acute coronary syndrome to estimate their inhospital, 6-month to 3-year mortality. It involves all of the following variables EXCEPT?

A 50 year old man presents with acute central chest pain. On examination, his pulse is 90 regular, BP 120/80, JVP +1cm. Chest was clear and no pedal edema. His serum creatinine is 90. Serum troponin is 300. His CXR is normal. ECG shows 1mm ST depression over lead V2-V6. You decide to treat him as a NSTEMI and subsequently referred him to cardiology for a coronary angiogram. His angiogram was performed within 24 hours of his presentation.

Which of the following would be the likely benefit from early invasive intervention in this man?

A 67 year old man is referred to the cath lab following an acute coronary syndrome (STEMI). The angiogram revealed that the culprit lesion was in the left circumflex artery so a drug eluting stent was placed successfully. However, this man was also noted to have multi-vessel disease on his angiography.

Which of the following intervention would lead to the best long term outcome?

A 50 year old man presents to a rural hospital with acute central chest pain. On examination, his pulse is 90 regular, BP 120/80, JVP +1cm. Chest was clear and no pedal edema. His serum creatinine is 90. Serum troponin is 20. His CXR is normal. ECG shows 3mm ST elevation over lead V2-V6. You diagnosed him as having an anterior STEMI and he is immediately thrombolysed. He is then subsequently referred to cardiology for a coronary angiogram. His angiogram was performed within 6 hours of his presentation.

Which of the following would be the likely benefit from early invasive intervention in this man?

Which of the following statement regarding Dabigatran is incorrect?

A 54 year old man with a background of atrial fibrillation presents with a Non-STEMI. He then undergoes a PCI and receives a second generation drug eluting stent. His bleeding risk is low when compared to the risk of stent thrombosis. Which of the following would be the most appropriate therapy following his PCI?

A 75 year old man with a background of non-valvular atrial fibrillation (CHADS2 score of 3) on warfarin had just undergone a PCI with a single stent placement in his left circumflex artery.

Which of the following drug combination post-PCI would be the safest in terms of future bleeding risk?

The following are all indications for cardiac transplant except?

In addition to statin, which of the following medication has been proven to cause a significant reduction of LDL cholesterol by approximately 60 percent?

Inclisiran lowers the body’s serum LDL by which mechanism?

A 50 year old man has been admitted with an acute coronary syndrome. He has been started on aspirin, clopidogrel, metoprolol, simvastatin and cilazapril. His measured LDL is 3.2 mmol/L. In view of this result, which of the following medication could be added to help reduce his cardiovascular mortality?

A 62-year-old man with type 2 diabetes and hypertension is on long term aspirin, quinapril, metoprolol and insulin. He presents with two hours of central chest pain. A diagnosis of non-ST elevation myocardial infarction is made. He proceeds to have coronary angiography which demonstrates diffuse three-vessel coronary artery disease. He is discharged home with the introduction of a long acting nitrate to await elective coronary artery surgery. He represents two weeks later with malaise and abdominal pain. His serum creatinine has increased to 450 mg/dl from a serum creatinine of 140 mg/dl on his previous admission.

Which of the following is the most likely cause of the deterioration in renal function?

Apixaban is a novel oral direct factor Xa inhibitor and is recommended for use in patients with non-valvular atrial fibrillation.

What superior advantage does this medication have over warfarin?

Which of the following is not consistent with the diagnosis of complete heart block?

The Angiopoietin-like 3 (ANGPTL3) plays an important role in which body mechanism?
