    Incorrect

    • A 60 yr. old patient with hypertension attended his regular clinic. His compliance was poor. His blood pressure was 180/100 mmHg. His pulse rate was 85 bpm which was irregularly irregular. On examination there was bibasal crepitation. No murmurs were heard. What is the most likely cause for these findings?

      Your Answer: Cor pulmonale

      Correct Answer: Left ventricular hypertrophy

      Explanation:

      Left ventricular hypertrophy due to long standing hypertension is the most probable cause. The irregularly irregular pulse was suggestive of atrial fibrillation, which is due to diastolic dysfunction. Poor ventricular filling causes pulmonary congestion which manifests as bibasal crepitations.

    Incorrect

    • A 65 yr. old previously well man was referred due to an abnormal heart sound which was detected during a medical check up. On examination he looked well. His blood pressure was 120/70 mmHg and pulse rate was 68 bpm which was regular. His jugular venous pressure was not elevated and he didn't have ankle oedema. He had an early diastolic murmur, best heard at the left sternal edge, which was more clear in expiration when the patient leant forward. His lungs were clear. His FBC, Urea and electrolytes, LFTs and lipid profile were normal. His ECG showed sinus rhythm. His chest X-ray was normal. Echocardiography showed mild to moderate aortic regurgitation with normal left ventricular size and normal function. Which of the following is the most appropriate way of managing this patient?

      Your Answer: Start him on aspirin

      Correct Answer: Start him on an angiotensin-converting enzyme (ACE) inhibitor

      Explanation:

      Although this patient’s left ventricular function is normal at the time of examination, there is chance of deterioration of it due to aortic regurgitation. It is found that ACE inhibitors slow the development of left ventricular dysfunction. So this patient should be started on an ACE inhibitor.

    Incorrect

    • Which of the following is the site where B-type natriuretic peptide is mainly secreted?

      Your Answer: Juxtaglomerular cells

      Correct Answer: Ventricular myocardium

      Explanation:

      B-type natriuretic peptide (BNP) is secreted mainly from the left ventricle and it is secreted as a response to stretching caused by increased ventricular blood volume.

    Incorrect

    • A 26 yr. old male was being investigated further following several hypertensive episodes. There was a marked difference in his systolic blood pressures between the right brachial and the right femoral arteries. Which of the following is most probable diagnosis?

      Your Answer:

      Correct Answer: Coarctation of the aorta

      Explanation:

      From the given physical findings (the difference in BP between the radial and femoral arteries), the most probable diagnosis is coarctation of the aorta.

    Incorrect

    • A 60 yr. old man presented with severe central chest pain for the last 2 hours. He was on insulin for diabetes mellitus and he was dependent on haemodialysis because of end stage renal failure. He had undergone haemodialysis 48 hours prior to this presentation. His ECG showed an acute inferior myocardial infarction. Despite thrombolysis and other appropriate treatment, he continued to have chest pain after 6 hours from the initial presentation. His blood pressure was 88/54 mmHg and he had bibasal crepitations. His investigation results are given below. Serum sodium 140 mmol/l (137-144), Serum potassium 6.6 mmol/l (3.5-4.9), Serum urea 50 mmol/l (2.5-7.5), Serum creatinine 940 μmol/l (60-110), Haemoglobin 10.2g/dl (13.0-18.0), Troponin T >24 g/l (<0.04), Left ventricular ejection fraction was 20%. What is the most appropriate management for this patient?

      Your Answer:

      Correct Answer: Coronary angiography and rescue PCI

      Explanation:

      According to the history the patient has cardiogenic shock and pulmonary oedema. On-going ischaemia is indicated by persisting symptoms. So the most appropriate management is coronary angiography and rescue PCI. There are no indications for blood transfusion at this moment and it will aggravate the pulmonary oedema. Haemodialysis, beta blockers and furosemide cannot be given due to low blood pressure.

    Incorrect

    • A 30 yr. old male presented with exercise related syncope and dyspnoea for 2 weeks. His father passed away at the age of 40, due to sudden cardiac death. His ECG showed left ventricular hypertrophy with widespread T wave inversions. Which of the following is the most appropriate next investigation to confirm the diagnosis?

      Your Answer:

      Correct Answer: Transthoracic echo

      Explanation:

      The most likely diagnosis is hypertrophic obstructive cardiomyopathy which is suggestive by the history, positive family history and ECG findings. Two-dimensional echocardiography is diagnostic for hypertrophic cardiomyopathy. In general, a summary of echocardiography findings includes abnormal systolic anterior leaflet motion of the mitral valve, LV hypertrophy, 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, and partial systolic closure of the aortic valve in midsystole.

    Incorrect

    • A 65 yr. male patient was started on warfarin for chronic atrial fibrillation (AF). Which of the following clotting factors is not affected by warfarin?

      Your Answer:

      Correct Answer: Factor XII

      Explanation:

      Carboxylation of factor II, VII, IX, X and protein C is affected by warfarin. Factor XII is not affected.

    Incorrect

    • A 42 yr. old male patient who was on enalapril for hypertension presented with generalized body weakness. Investigations revealed hyperkalaemia. Which of the following can be expected in his ECG?

      Your Answer:

      Correct Answer: Tall, tented T waves

      Explanation:

      In hyperkalaemia the ECG will show tall, tented T waves as well as small P waves and widened QRS complexes.

    Incorrect

    • A 50 yr. old male patient presented with acute chest pain and a non ST elevation myocardial infarction (NSTEMI) was diagnosed. He was threated with aspirin 300mg and 2 puffs of glyceral trin (GTN) spray. According to NICE guidelines, which of the following categories of patients should receive clopidogrel?

      Your Answer:

      Correct Answer: All patients

      Explanation:

      According to NICE guidelines (2013) all people who have had an acute MI treatment should be offered with ACE inhibitor, dual antiplatelet therapy (aspirin plus a second antiplatelet agent), a beta-blocker and a statin.

    Incorrect

    • 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:

      Correct 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.
