    Correct

    • A 60 yr. old previously well male patient was admitted with acute severe central chest pain associated with excessive sweating and nausea for the past 45 minutes. On examination he was found to have xanthelasma. His blood pressure was 170/100 mmHg and pulse rate was 104 bpm. His ECG showed ST elevation more than 2mm in leads II, III and aVF. His troponin T was 120 ng/ml. His FBC and renal functions were normal. He was given aspirin, clopidogrel, morphine and IV 5mg of atenolol. Which of the following is the most appropriate next step?

      Your Answer: Immediate referral to cardiologist for primary angioplasty

      Explanation:

      The diagnosis is acute inferior ST elevation myocardial infarction so the most appropriate management is primary angioplasty.

    Incorrect

    • Which of the following indicates the opening of tricuspid valve in jugular venous waveform?

      Your Answer: x descent

      Correct Answer: y descent

      Explanation:

      The a wave indicates atrial contraction. The c wave indicates ventricular contraction and the resulting bulging of tricuspid valve into the right atrium during isovolumetric systole. The v wave indicates venous filling. The x descent indicates the atrium relaxation and the movement of the tricuspid valve downward. The y descent indicates the filling of the ventricle after tricuspid opening.

    Incorrect

    • A 60 yr. old male smoker and a known hypertensive presented with central chest pain radiating to the back. On examination he was tachycardic and hypotensive. His ECG showed inferior ST elevation and his transoesophageal echocardiogram showed a double lumen in the ascending aorta. Which of the following is the most probable diagnosis?

      Your Answer:

      Correct Answer: Dissecting aortic aneurysm

      Explanation:

      The classic history in this high risk patient is suggestive of a dissecting aortic aneurysm. His transoesophageal echocardiogram confirms the diagnosis. ST elevation in ECG is probably due to the extension of the dissection of the aorta which results in compromised coronary blood supply.

      Your Answer:

      Correct Answer: Initiate and then continue treatment with heparin until delivery

      Explanation:

      Warfarin is contraindicated during pregnancy due to its teratogenic effects. She should be given heparin throughout her pregnancy. It can be converted to warfarin if necessary after the delivery.

    Incorrect

    • A 25 yr. old female presented with a history of sudden collapse. She had been playing netball and had suddenly collapsed. This collapse had been accompanied by a brief period of loss of consciousness. She experienced palpitations for a brief period prior to losing consciousness. On examination her BP was 120/70 mmHg and pulse rate was 72 bpm, which was regular. The rest of the examination was also normal. She had similar experience of collapse, about two years ago. She was well except for these two incidents and she has not been on any medication. All the investigations done at the first presentation (2 years ago), including FBC, ECG and echocardiography were normal. Her ECG done at this presentation revealed QT prolongation of 0.50 s. FBC, CXR and other investigations were normal. Which of the following is the best way of managing this patient?

      Your Answer:

      Correct Answer: Start on a beta-blocker

      Explanation:

      Beta-blockers are drugs of choice for patients with LQTS. The protective effect of beta-blockers is related to their adrenergic blockade, which diminishes the risk of cardiac arrhythmias. They may also reduce the QT interval in some patients.

    Incorrect

    • Which of the following is suggestive of co-existence of mitral regurgitation and mitral stenosis?

      Your Answer:

      Correct Answer: Displaced apex beat

      Explanation:

      Apex beat displacement is caused by mitral regurgitation and because it is not found in mitral stenosis, it is suggestive of mixed mitral disease. The other given responses occur in mitral stenosis.

    Incorrect

    • A 60 yr. old male presented with ventricular tachycardia which was successfully cardioverted. To check whether he had prolonged QT interval, which of the following is the most appropriate method to measure the QT interval in ECG?

      Your Answer:

      Correct Answer: Time between the start of the Q wave and the end of the T wave

      Explanation:

      The QT interval is the time from the start of the Q wave to the end of the T wave. It represents the time taken for ventricular depolarisation and repolarisation. The QT interval should be measured in either lead II or V5-6.

    Incorrect

    • A 72 yr. old male presented to the Emergency Department with a broad complex tachycardia. Which of the following features is more suggestive that this has resulted because of a supraventricular tachycardia (SVT) rather than a ventricular tachycardia (VT)?

      Your Answer:

      Correct Answer: Absence of QRS concordance in chest leads on ECG

      Explanation:

      To differentiate ventricular tachycardia (VT) from supraventricular tachycardia (SVT) with aberrant conduction the following electrocardiographic features should be looked for:

      Evidence of preceding atrial activity for SVT. Oesophageal leads are helpful if P waves are hidden in the QRS complex.
      QRS duration more than 140 ms for VT.
      QRS morphology: Features of QRS morphology that favour SVT are RBBB or triphasic patterns like rSR in V1 and qRS in V6. Monophasic pattern like R or qR in V1 and rS or QS in V6 or multiple morphology QRS complexes favour VT.
      AV dissociation for VT.

    Incorrect

    • A 50 yr. old male presented with episodes of collapse during the last month. Each episode persisted for about 2-3 minutes. They were self-limiting and associated with twitching of the limbs. There was no associated tonic-clonic movements, tongue biting, urinary or faecal incontinence. On examination he had reversed splitting of S2 and an ejection systolic murmur at the right sternal border. His electrocardiogram (ECG) showed left ventricular hypertrophy with strain pattern. CXR showed an area of calcification over the cardiac silhouette. Which of the following is the most probable diagnosis of this patient?

      Your Answer:

      Correct Answer: Aortic stenosis

      Explanation:

      The classic triad of symptoms in patients with aortic stenosis is chest pain, heart failure and syncope. Pulsus parvus et tardus, pulsus alternans, hyperdynamic left ventricle, reversed splitting of the S2, prominent S4 and systolic murmur are some of the common findings of aortic stenosis. A calcified aortic valve is found in almost all adults with hemodynamically significant aortic stenosis.

    Incorrect

    • A 60 yr. old male patient with NSTEMI was started on low dose aspirin as secondary prevention. Which of the following, describe the action of aspirin as an antiplatelet agent?

      Your Answer:

      Correct Answer: Inhibits the production of thromboxane A2

      Explanation:

      The antithrombotic action of aspirin is due to inhibition of platelet function by acetylation of the platelet cyclooxygenase (COX) at the functionally important amino acid serine529. This prevents the access of the substrate (arachidonic aid) to the catalytic site of the enzyme at tyrosine385 and results in an irreversible inhibition of platelet-dependent thromboxane formation.

    • A 35 yr. old female with systemic lupus erythematosus (SLE) was brought to Casualty, complaining of chest pain and worsening difficulty in breathing for the past 36 hrs. On examination she was tachypnoeic, her BP was 85/65 mmHg and peripheral oxygen saturation was 98% on air. Her cardiac examination was normal but her jugular venous pressure was elevated. She didn't have ankle oedema. Her ECG showed sinus tachycardia and her CXR showed clear lung fields with a slightly enlarged heart. Which of the following is the most appropriate next step?

      Your Answer:

      Correct Answer: Urgent transthoracic echocardiogram

      Explanation:

      Acute breathlessness in SLE can be due to a pericardial effusion or a pulmonary embolism. Normal peripheral oxygen saturation and normal ECG, make the diagnosis of pulmonary embolism less likely. To exclude pericardial effusion, an urgent transthoracic echocardiogram is needed.

On examination he was tachycardic, hypotensive and had an elevated JVP, pulsus paradoxus and muffled heart sounds. Respiratory examination was unremarkable. Which of the following is most probable diagnosis?

      Your Answer:

      Correct Answer: Cardiac tamponade

      Explanation:

      Becks triad (hypotension, elevated systemic venous pressure, often with jugular venous distention and muffled heart sounds) is a characteristic collection of clinical findings found in cardiac tamponade. Pulsus paradoxus is also associated with it. The history and clinical findings in this scenario are compatible with the diagnosis of cardica tamponade. The normal respiratory examination excludes tension pneumothorax.

On examination his blood pressure was 140/80 mmHg and pulse rate was 88 bpm. His ECG showed atrial fibrillation and the CT scan of his brain was normal. Which of the following is the most appropriate management for this patient?

      Your Answer:

      Correct Answer: Warfarin

      Explanation:

      CHAâ‚‚DSâ‚‚-VASc score is used for atrial fibrillation stroke risk calculation.
      Congestive heart failure – 1 point
      Hypertension – 1 point
      Age ≥75 years – 2 points
      Diabetes mellitus – 1 point
      Stroke/Transient Ischemic Attack/Thromboembolic event – 2 points
      Vascular disease (prior MI, PAD, or aortic plaque) – 1 point
      Age 65 to 74 years – 1 point
      Sex category (i.e., female sex) – 1 point
      Score of 2 or more is considered as high risk and anticoagulation is indicated. This patient’s score is 4, so he needs life-long warfarin to prevent a stroke.

    Incorrect

    • A previously well 33 yr. old female is admitted with a history of recurrent episodes of palpitations. She has not experience chest pain but rather a feeling of a rapidly beating heart. She frequently drinks coffee and alcohol. Her blood pressure is 120/80 mmHg and pulse rate 200 bpm which is regular. There is no sign of heart failure. Her ECG reveals a narrow complex tachycardia. She is given 3mg of IV adenosine but there is no response. Which of the following is the most appropriate management if she doesn't respond to 6mg of IV adenosine?

      Your Answer:

      Correct Answer: 12mg IV adenosine

      Explanation:

      If 3mg of adenosine has no effect, then adenosine 6 mg can be given by rapid IV push. If patient does not convert to a normal rhythm, give another dose of adenosine 12 mg via rapid IV push. This can be repeated if there is no response. If no response, diltiazem or beta-blockers can be given as alternatives.

He was treated with streptokinase. 2 days later he was sweating excessively and he was found to be hypotensive. Which of the following cannot be considered as a reason for this presentation?

      Your Answer:

      Correct Answer: Hypotensive effect of streptokinase

      Explanation:

      Hypotensive effect of streptokinase occurs during the streptokinase infusion which is usually transient. Acute mitral regurgitation due to rupture of papillary muscles, ventricular septal defects and reinfarctions (left or right) are known to cause hypotension after 24 hrs. Pulmonary embolism is less likely but cannot be excluded.

    Incorrect

    • A 60 yr. old man presented with difficulty in breathing. On examination he was severely dyspnoeic and tachycardic. What is the clinical sign that would favour the diagnosis of cardiac tamponade over constrictive pericarditis?

      Your Answer:

      Correct Answer: Pulsus paradoxus

      Explanation:

      Pulsus paradoxus is defined as the exaggerated fall in systolic blood pressure during inspiration by greater than 10 mmHg. Cardiac tamponade is the classic cause of pulsus paradoxus. Kussmaul’s sign (a rise in the jugular venous pressure on inspiration) is mostly seen in constrictive pericarditis. Hypotension, muffled heart sounds and raised JVP can be seen in both conditions.

    Incorrect

    • A 70 yr. old man underwent temporary transvenous pacing. While in the coronary care unit he developed pre-syncope. His pulse rate was 30 bpm. His ECG showed pacing spikes which were not related to QRS complexes. What is the most appropriate action that can be taken?

      Your Answer:

      Correct Answer: Increase the pacing voltage to a maximum

      Explanation:

      Pacemaker spikes on the ECG indicate that pacemaker is functioning. The most probable cause for this presentation is the change of the position of the tip of the pacing wire. Increasing the voltage will solve the problem. If it works, repositioning of the pacing wire should be done.

    Incorrect

    • A 30 yr. old male patient presented with palpitations that occur randomly at rest. There have however been episodes of fast palpitations and dizziness on exertion. On examination there was a systolic murmur at the apex as well as a prominent apex beat and the chest was clear. Which of the following is LEAST likely to suggest a diagnosis of hypertrophic cardiomyopathy?

      Your Answer:

      Correct Answer: A history of hypertension for 10 years

      Explanation:

      Hypertrophic cardiomyopathy is an autosomal dominant condition. Patients present with sudden cardiac death, dyspnoea, syncope and presyncope, angina, palpitations, orthopnoea and paroxysmal nocturnal dyspnoea, Congestive heart failure and dizziness. Physical findings include double or triple apical impulse, prominent a wave in the JVP, an ejection systolic crescendo-decrescendo murmur and a holosystolic murmur at the apex and axilla of mitral regurgitation.
      ECG shows ST-T wave abnormalities and LVH, axis deviation (right or left), conduction abnormalities (P-R prolongation, bundle-branch block), sinus bradycardia with ectopic atrial rhythm, atrial enlargement, abnormal and prominent Q wave in the anterior precordial and lateral limb leads.
      2D echocardiography shows abnormal systolic anterior leaflet motion of the mitral valve, LVH, left atrial enlargement, small ventricular chamber size, septal hypertrophy with septal-to-free wall ratio greater than 1.4:1, mitral valve prolapse and mitral regurgitation, decreased midaortic flow, partial systolic closure of the aortic valve in midsystole

    Incorrect

    • A 42 yr. old previously well woman presented with acute severe central chest pain for the past 2 hours. She has a family history of premature coronary artery disease. Her husband passed away recently due to prostate cancer. On examination her blood pressure was 130/80 mmHg and pulse rate was 80 bpm. Her ECG showed ST segment elevation and her troponin was slightly elevated. Emergency angiogram revealed slight wall irregularities with no luminal obstruction. Cardiovascular MR showed an apical ballooning of the myocardium resembling an octopus pot. Which of the following is the most likely cause for the ST segment elevation?

      Your Answer:

      Correct Answer: Takotsubo cardiomyopathy

      Explanation:

      Causes for ST segment elevation other than myocardial infarction
      Natural variants
      -Early repolarization
      -Left ventricular hypertrophy and hypertrophic cardiomyopathy
      -Left bundle branch block
      Artefacts
      -Leads mispositioning
      -Electrical cardioversion
      Cardiovascular diseases
      -Pericarditis/ Myocarditis
      -Aortic dissection
      -Prinzmetal’s angina
      -Takotsubo Cardiomyopathy
      -Brugada Syndrome and arrhythmogenic right ventricular cardiomyopathy/dysplasia
      Pulmonary diseases
      -Pulmonary thromboembolism
      -Pneumothorax
      -Atelectasis and pulmonary metastases
      Gastrointestinal diseases
      -Acute pancreatitis
      -Acute cholecystitis
      Other conditions
      -Hyperkalaemia
      -Drug induced ST segment elevation (e.g. – clozapine)
      -Haemorrhagic cerebrovascular disease

      Coronary artery disease and myocardial infarction can be excluded with a negative angiogram and a slightly elevated troponin. Hypertrophic cardiomyopathy can be excluded with cardiovascular MR findings. Left ventricular aneurysm usually occurs following a myocardial infarction, but there is no positive history for that. The characteristic findings on cardiovascular MR confirms the diagnosis of Takotsubo cardiomyopathy.

      Your Answer:

      Correct Answer: B-blocker and statin

      Explanation:

      Beta blockers and calcium channel blockers have proven prognostic benefits. Nitrates don’t have any proven prognostic benefits. A statin is indicated for a patient with angina and cholesterol level of 5.5 to 8.5 to prevent risk of myocardial infarction. So the preferred combination from the given answers is beta blocker + statin.

    Incorrect

    • A 42 yr. old man presented with palpitations and shortness of breath on exertion. On examination his lungs were clear and heart sounds were normal. There was a left sided parasternal heave. His electrocardiogram (ECG) revealed atrial fibrillation with right axis deviation. Echocardiography showed dilated right heart chambers. Left and right heart catheterisation study revealed the following: Inferior vena cava Oxygen saturations 63 %, Superior vena cava Oxygen saturations 59 %, Right atrium Oxygen saturations 77 %, Right ventricle Oxygen saturations 78 %, Pulmonary artery Oxygen saturations 82 %, Arterial saturation Oxygen saturations 98 %. What is the most likely diagnosis from the following answers?

      Your Answer:

      Correct Answer: Atrial septal defect

      Explanation:

      Right ventricular volume overload is indicated by a parasternal heave and right axis deviation. Oxygen saturation in right atrium is higher than oxygen saturation of the inferior and superior vena cavae. So the most probable diagnosis is atrial septal defect.
