MCCQE - Medical Council of Canada Qualifying Examination Cardiovascular Disease Management Questions and Answers

Question 1

A 68-year-old male with a history of hypertension and type 2 diabetes presents for a routine follow-up. His blood pressure is 145/92 mmHg despite adherence to lifestyle modifications. According to the 2025 Hypertension Canada guidelines, which of the following is the most appropriate initial pharmacological treatment?

Accepted Answer

A single-pill combination of an ACE inhibitor and a dihydropyridine calcium channel blocker

Answer

The 2025 Hypertension Canada guidelines recommend initiating pharmacotherapy for adults with a blood pressure ≥ 140/90 mmHg. For most patients requiring medication, upfront combination therapy, ideally as a single-pill combination, is recommended. The preferred combinations are an ACE inhibitor or ARB plus either a dihydropyridine calcium channel blocker or a thiazide/thiazide-like diuretic.

Question 2

A 55-year-old woman with no prior history of cardiovascular disease is found to have a non-fasting LDL-cholesterol level of 5.2 mmol/L. Her 10-year cardiovascular disease risk is calculated to be 18% using the Framingham Risk Score. According to the 2021 Canadian Cardiovascular Society (CCS) Dyslipidemia Guidelines, what is the most appropriate next step in management?

Accepted Answer

Initiate moderate-intensity statin therapy.

Answer

According to the 2021 CCS Dyslipidemia Guidelines, for individuals in the intermediate-risk category (Framingham Risk Score 10-19.9%), a discussion about initiating moderate-intensity statin therapy is recommended if LDL-C is ≥3.5 mmol/L. High-intensity statin is typically reserved for those with a risk score ≥20% or established atherosclerotic cardiovascular disease.

Question 3

A 72-year-old male with a new diagnosis of non-valvular atrial fibrillation has a CHADS2 score of 3. He is being started on anticoagulation for stroke prevention. Which of the following is a key component of his management plan according to the Canadian Cardiovascular Society (CCS) guidelines?

Accepted Answer

Screening for and managing modifiable cardiovascular risk factors such as hypertension and obesity.

Answer

The 2020 CCS/CHRS Atrial Fibrillation Guidelines emphasize a comprehensive approach to management. A crucial part of this is the management of modifiable cardiovascular risk factors (e.g., hypertension, obesity, sleep apnea) to reduce cardiovascular events and decrease the burden of atrial fibrillation.

Question 4

A 62-year-old man underwent a percutaneous coronary intervention (PCI) with a drug-eluting stent for stable ischemic heart disease. He has no history of bleeding or stroke. Based on the Canadian Cardiovascular Society/Canadian Association of Interventional Cardiology (CCS/CAIC) antiplatelet therapy guidelines, what is the recommended duration of dual antiplatelet therapy (DAPT)?

Accepted Answer

6 months

Answer

For patients undergoing PCI for a non-acute coronary syndrome indication, such as stable ischemic heart disease, the CCS/CAIC guidelines recommend 6 months of DAPT with ASA and clopidogrel. An extension up to 1 year can be considered.

Question 5

Which of the following is the primary goal of initiating a rhythm-control strategy in a symptomatic patient with atrial fibrillation, according to current Canadian cardiovascular guidelines?

Accepted Answer

To improve quality of life and reduce AF-related symptoms.

Answer

The primary indication for a rhythm-control strategy (using antiarrhythmic drugs or ablation) in patients with atrial fibrillation is to reduce AF-related symptoms and improve quality of life. While rhythm control can have other benefits, symptom improvement is the main goal. Stroke prevention with anticoagulation is still required based on the patient's risk profile, irrespective of the rhythm-control strategy.
