Cardiologist Interview Questions
& Model Answers, 2026

Start with pretest probability from age, sex and symptom character, then choose by what the answer will change. Anatomical testing with coronary computed tomography angiography is strong for ruling out disease in lower to intermediate probability patients and adds plaque information; functional testing with stress imaging is better where ischaemia burden guides revascularisation or where the patient has known disease. Consider calcium scoring, renal function, body habitus and radiation. Say what you would not test at all, because that is the more revealing half of the answer.

Four pillars started early and titrated rather than sequenced slowly one at a time: an angiotensin receptor-neprilysin inhibitor or ACE inhibitor, a beta blocker, a mineralocorticoid receptor antagonist, and an SGLT2 inhibitor. Start low doses of several agents rather than maximising one, watch renal function and potassium, manage volume with diuretics separately, and reassess ejection fraction after adequate therapy before device consideration. Say how you handle hypotension and renal impairment during titration, because that is where most patients stall.

Anticoagulation is decided by stroke risk score independent of the rhythm strategy and independent of symptom burden, balanced against bleeding risk that you modify rather than use as a reason to withhold. For the rhythm strategy, favour early rhythm control in recently diagnosed atrial fibrillation, symptomatic patients, heart failure and younger patients, considering ablation where drugs fail or are undesirable. Rate control is reasonable in older, minimally symptomatic patients. Address the drivers — sleep apnoea, alcohol, weight, hypertension.

Field activation with pre-hospital electrocardiogram transmission, single-call activation of the catheterisation laboratory, bypassing the emergency department where the pathway allows, and a first-medical-contact-to-device target within the recommended time, with a defined transfer target for spoke hospitals. Audit every case with the delays broken down, review false activations rather than punishing them, and give feedback to emergency medical services. Say what you would do with a service that consistently misses its target.

Intervene for symptomatic severe stenosis, and for asymptomatic severe disease with reduced ejection fraction, an abnormal exercise test or very severe gradients with markers of rapid progression. The choice between surgical replacement and a transcatheter approach rests on surgical risk, age and life expectancy, anatomy and access, valve durability considerations and the possibility of future procedures. Say that the decision belongs to a structural heart team meeting and describe your role in it.

After at least three months of optimal guideline-directed medical therapy with a persistently reduced ejection fraction at or below the accepted threshold, in a patient with a reasonable expectation of meaningful survival, considering ischaemic versus non-ischaemic aetiology and time from infarction. Reassess ejection fraction after therapy rather than implanting on the initial number. Discuss shocks, driving, end-of-life deactivation and the alternative of a wearable device during the waiting period.

Order to answer a question that will change management, apply the appropriate use criteria, and resist routine surveillance intervals shorter than the guideline for stable disease. Say how you handle a referrer requesting an inappropriate study — a conversation and an alternative rather than a rubber stamp. Cardiology practices generate substantial ancillary revenue from imaging, so a candidate with an explicit stewardship position is signalling something the group will want to hear.

A missed dissection, a stress test that reassured falsely, an anticoagulation decision that produced a bleed: name it, describe the review, and say what changed. Cardiology attracts confident clinicians and panels deliberately probe for the ones who cannot say this.

Give concrete practices: response time to consults, clear documentation of the plan, availability for the borderline case, and how you handle a disagreement about admission or activation. Referral relationships determine a cardiology practice's volume, so this is assessed carefully.

Door-to-balloon reduction, heart failure readmission, guideline-directed therapy titration clinics, anticoagulation stewardship: give the baseline, the intervention, and the measured change. Cardiology is heavily benchmarked and groups value physicians who move published metrics.

Device deactivation, declining further revascularisation, transitioning an advanced heart failure patient to palliative care: describe how you framed it, involved the family, and documented it. This is increasingly a core cardiology competency rather than a peripheral one.

Anchor on the specialty series: cardiologists have a BLS OEWS May 2025 median of $496,010 a year with the top 10% above $712,130. Then say the number depends on the subspecialty, whether the role is invasive, interventional or non-invasive, the call structure and the ancillary arrangement, and ask for the group's actual production figures before committing.

Ask whether you participate in the technical component of echocardiography, nuclear imaging and vascular studies, or whether that revenue sits with the hospital under an employment model. In a private group ancillary participation can be a large share of income; in an employed model it usually is not, which is why headline employed salaries look lower for the same clinical work. Compare like with like.

Catheterisation laboratory call frequency and any stipend, protected time post-call, malpractice with tail, partnership timeline and buy-in, restrictive covenant, continuing medical education and licensure funding, and administrative or medical directorship stipends. If the role includes structural heart or electrophysiology procedures, get the training and proctoring commitment in writing.
