Iraqi Board Cardiology common mistakes
Iraqi Board Cardiology · Understand the traps and how to avoid them.
When asked for the next step in acute chest pain, the candidate names the definitive treatment (e.g. primary PCI) instead of the immediate action (ECG within 10 minutes, aspirin, monitoring), skipping the diagnostic step that the question is actually testing.
Exam stems often present a dramatic scenario (crushing chest pain, diaphoresis) that primes recall of management algorithms, so candidates jump to the endpoint of the algorithm and ignore the sequence the question asks about. Time pressure reinforces this shortcut.
What to do instead
Before answering any 'next step' item, write the clinical pathway in order on scratch paper (symptom onset, first contact, ECG, biomarkers, risk stratification, reperfusion decision). Then locate the exact point in the stem and choose only the action that comes next. Practise with stems that deliberately place the patient at different points in the pathway.
The candidate interprets ECGs by pattern recognition of single features (e.g. 'ST elevation means STEMI') without systematically checking rate, rhythm, axis, intervals, hypertrophy, and comparing with prior tracings, so they miss reciprocal changes, benign early repolarisation, LVH pseudoinfarct patterns, or a subtle conduction disorder.
Pattern recognition is fast and is how experienced clinicians often read ECGs, but under exam conditions it degrades into anchoring on the most visually striking abnormality. Candidates also under-use the clinical context in the stem that would reframe the tracing.
What to do instead
Adopt a fixed reading sequence (rate, rhythm, axis, PR/QRS/QT, hypertrophy, ischaemia/infarction with reciprocal leads, comparison to old ECG) and verbalise it while practising. For every ST-elevation tracing, explicitly ask: is there reciprocal depression, is the distribution territorial, does the morphology fit the clinical story? Review 20 tracings per week with a written report before checking the answer.
The candidate labels any breathless patient with a reduced ejection fraction as 'heart failure with reduced EF' and treats the number as the diagnosis, without addressing the underlying aetiology (ischaemic, valvular, infiltrative, toxic, tachyarrhythmia) or the haemodynamic profile (wet/dry, warm/cold).
EF is the easiest variable to recall and is heavily emphasised in teaching, so it crowds out aetiological and haemodynamic reasoning. Questions that ask for the cause or the immediate management of decompensation are then answered with generic heart-failure therapy.
What to do instead
For every heart-failure vignette, write three lines: EF category, likely aetiology with the evidence for it, and congestion/perfusion status. Then map therapy to that profile (diuretic for congestion, inotrope/vasopressor for hypoperfusion, device therapy only after optimisation). Practise distinguishing HFrEF, HFmrEF, HFpEF and their different evidence bases.
The candidate manages hypertension as a single number, choosing drug classes by habit rather than by compelling indication and comorbidity (e.g. missing ACE inhibitor/ARB in diabetic proteinuria, avoiding ACE inhibitor in bilateral renal artery stenosis, choosing a beta-blocker as first-line in an uncomplicated elderly patient).
Hypertension guidelines are long and candidates memorise a preferred first-line list without the exceptions. Exam items often hinge on the exception, and candidates answer with the general rule.
What to do instead
Build a two-column table: comorbidity versus preferred and avoided agents (diabetes with albuminuria, CKD, heart failure, post-MI, pregnancy, asthma, gout, black African ancestry). For each practice item, state the compelling indication before selecting the drug, and check for a contraindication hidden in the stem.
The candidate answers valvular disease questions by naming the lesion but omits severity assessment, timing of intervention, and the distinction between symptoms attributable to the valve and symptoms from another cause (e.g. recommending surgery for moderate asymptomatic aortic stenosis, or missing that a breathless patient with severe mitral regurgitation needs assessment for intervention).
Lesion recognition is taught early and tested often, so candidates stop at the diagnosis. Severity criteria (valve area, gradients, jet width, pulmonary pressures) and trigger points for surgery are less rehearsed and easily confused.
What to do instead
For each valve lesion, memorise a compact card: auscultation findings, echo severity thresholds, and guideline triggers for intervention (symptoms, LV dysfunction, pulmonary hypertension, rapid progression, concomitant disease). Rehearse 'severe plus symptom or LV dysfunction equals refer' as a decision rule rather than a fact.
The candidate reads a rhythm strip and commits to a diagnosis before checking whether the patient is stable, and then selects a treatment that is correct for the rhythm but wrong for the haemodynamic state (e.g. adenosine for unstable broad-complex tachycardia, or cardioversion without sedation in a stable patient).
Arrhythmia questions reward rhythm identification, and candidates treat the tracing as the whole question. The stability-first principle is taught but not practised as a decision gate under time pressure.
What to do instead
Always answer in the order: unstable (pulse, blood pressure, ischaemia, heart failure) then synchronised cardioversion; stable then rhythm-specific therapy. For broad-complex tachycardia, default to treating as ventricular tachycardia until proven otherwise. Practise 15 tachycardia scenarios stating stability before the rhythm.
The candidate answers congenital heart disease items using adult-acquired disease logic, missing shunt physiology, Eisenmenger status, cyanosis with and without pulmonary hypertension, and the fact that pregnancy and non-cardiac surgery carry lesion-specific risk.
Adult congenital cardiology is a small part of most training and candidates generalise from acquired disease. Shunt direction and its reversal are conceptually demanding and rarely rehearsed.
What to do instead
Learn a small set of anchor lesions (ASD, VSD, PDA, tetralogy of Fallot, coarctation, transposition post-repair, Fontan) with shunt direction, expected murmur, Eisenmenger risk, and pregnancy/surgery precautions. For each vignette, decide shunt direction from oxygen saturation and pulmonary pressures before choosing management.
The candidate attributes every hypotension or tachycardia in a monitored patient to the heart and misses tamponade, tension pneumothorax, sepsis, bleeding, or pulmonary embolism, and does not use bedside ultrasound or the clinical triad when it is offered.
Cardiology exams prime cardiac explanations, and candidates anchor on the specialty rather than the differential. Pericardial disease and right-heart causes are under-rehearsed relative to left-heart disease.
What to do instead
For any shock vignette, run a rapid aetiology checklist (pump, rate, volume, obstruction, sepsis, embolism) and look for the discriminating signs (pulsus paradoxus, raised JVP with clear lungs, tracheal shift, unilateral leg swelling). Practise identifying which bedside test would confirm each cause fastest.
The candidate treats imaging results as diagnoses, ordering or interpreting a test without asking whether it will change management, and failing to match test to question (e.g. CT coronary angiography in a patient with known heavy calcification, stress imaging in an acutely unstable patient, or missing that a normal troponin does not exclude unstable angina).
Imaging and biomarkers are memorable and heavily tested, so candidates select the most sophisticated test rather than the appropriate one. They also conflate test sensitivity with clinical certainty.
What to do instead
Before choosing a test, state the clinical question (rule out, rule in, risk stratify, assess severity), the pretest probability, and the action that follows each result. Learn the strengths and failure modes of ECG, echo, stress testing, CT, MR and nuclear imaging, and the limits of troponin timing and assays.
The candidate omits ethics, consent, capacity, and patient-safety reasoning from emergency answers, for example proceeding with thrombolysis or cardioversion without addressing consent in an incapacitated patient, or not escalating a deteriorating patient because the question seems purely clinical.
These domains are perceived as soft and are revised last, and candidates assume the exam only tests pathophysiology. In practice, items often embed a communication, capacity, or escalation decision that changes the correct option.
What to do instead
For every emergency scenario, ask three extra questions: is the patient capacitous, what is the least restrictive lawful route to treatment, and who must be informed or escalated? Review local and international guidance on emergency treatment without consent, DNACPR decisions, and disclosure of a serious diagnosis, and practise short ethics vignettes weekly.
