ABIM Cardiovascular Disease Study Tips by Domain
- When a tachyarrhythmia is present, first decide if the patient is hemodynamically unstable (hypotension, ischemic chest pain, altered mental status, shock, acute HF)—this is a priority rule for immediate synchronized cardioversion rather than additional diagnostic maneuvers.
- For regular narrow-complex SVT, vagal maneuvers then adenosine is first-line, but a key contraindication/red flag is irregular wide-complex tachycardia (suspected preexcited AF) where AV nodal blockers can precipitate VF.
- Atrial fibrillation management hinges on stroke prevention: use CHA2DS2-VASc to guide anticoagulation, and don’t fall for the trap that restoration of sinus rhythm eliminates the need for anticoagulation when risk is high.
- In wide-complex tachycardia, assume ventricular tachycardia until proven otherwise—a common ABIM trap is treating presumed SVT with aberrancy using AV nodal blockers in an older patient with structural heart disease.
- Bradyarrhythmias: symptomatic bradycardia or high-grade AV block requires atropine and often temporary pacing, and a red flag is Mobitz II or complete heart block (especially with wide QRS) where permanent pacing is typically indicated.
- QT prolongation with polymorphic VT (torsades de pointes) is treated with IV magnesium and correction of K/Mg, and the practical cue is to stop QT-prolonging drugs and avoid amiodarone/sotalol when acquired long-QT is the driver.
- In suspected ACS, obtain serial ECGs and high-sensitivity troponins; red flag: new ST-elevation or posterior MI pattern warrants immediate reperfusion rather than waiting for biomarkers.
- Use DAPT after ACS/PCI but reassess bleeding risk; common trap: continuing prasugrel in prior stroke/TIA (contraindicated) or forgetting GI bleed history when choosing P2Y12 inhibitor.
- For stable chest pain, match testing to pretest probability and ability to exercise; priority rule: avoid routine stress testing in very low-risk patients (false positives lead to unnecessary angiography).
- In STEMI, choose primary PCI when feasible; threshold cue: if first medical contact-to-device time will exceed guideline targets, give fibrinolysis unless contraindicated (e.g., prior intracranial hemorrhage).
- High-intensity statin is foundational in clinical ASCVD; common trap: stopping statin for mild, asymptomatic transaminase elevation—evaluate other causes and continue unless true hepatotoxicity or rhabdomyolysis.
- Recognize mechanical complications post-MI (papillary muscle rupture, VSD, free wall rupture); red flag: new harsh murmur, pulmonary edema, or sudden hypotension 2–7 days after MI requires urgent echo and surgical consultation.
- Severe aortic stenosis is high-risk when Vmax =4.0 m/s, mean gradient =40 mmHg, or AVA =1.0 cm2; red flag is syncope, angina, or dyspnea — don’t delay valve intervention once symptoms appear.
- In chronic aortic regurgitation, operate when symptoms develop or when LVEF =55% or LVESD >50 mm (or >25 mm/m2); common trap is being reassured by a “normal” EF in a markedly dilated LV.
- Primary (degenerative) MR: refer for repair when symptomatic severe MR or when LVEF =60% and/or LVESD =40 mm even if asymptomatic; red flag is new atrial fibrillation or pulmonary hypertension (PASP >50 mmHg at rest).
- Secondary (functional) MR: priority is GDMT for HFrEF and CRT when indicated; common trap is sending all severe MR to surgery — consider transcatheter edge-to-edge repair only if symptoms persist and anatomy is suitable.
- Mitral stenosis severity: valve area =1.5 cm2 is significant and =1.0 cm2 is severe; red flag is atrial fibrillation or prior embolic event — anticoagulate with warfarin (not DOACs) in rheumatic MS with AF.
- Suspected infective endocarditis in valvular disease: obtain 3 sets of blood cultures before antibiotics unless unstable; common trap is relying on TTE alone — TEE is preferred for prosthetic valves or persistent bacteremia.
- Severe aortic stenosis is high-risk when Vmax =4.0 m/s, mean gradient =40 mmHg, or AVA =1.0 cm2; red flag is syncope, angina, or dyspnea — don’t delay valve intervention once symptoms appear.
- In chronic aortic regurgitation, operate when symptoms develop or when LVEF =55% or LVESD >50 mm (or >25 mm/m2); common trap is being reassured by a “normal” EF in a markedly dilated LV.
- Primary (degenerative) MR: refer for repair when symptomatic severe MR or when LVEF =60% and/or LVESD =40 mm even if asymptomatic; red flag is new atrial fibrillation or pulmonary hypertension (PASP >50 mmHg at rest).
- Secondary (functional) MR: priority is GDMT for HFrEF and CRT when indicated; common trap is sending all severe MR to surgery — consider transcatheter edge-to-edge repair only if symptoms persist and anatomy is suitable.
- Mitral stenosis severity: valve area =1.5 cm2 is significant and =1.0 cm2 is severe; red flag is atrial fibrillation or prior embolic event — anticoagulate with warfarin (not DOACs) in rheumatic MS with AF.
- Suspected infective endocarditis in valvular disease: obtain 3 sets of blood cultures before antibiotics unless unstable; common trap is relying on TTE alone — TEE is preferred for prosthetic valves or persistent bacteremia.
- Acute pericarditis is diagnosed when =2 of: pleuritic chest pain, pericardial friction rub, diffuse ST elevation/PR depression, new/worsening effusion; red flag for myopericarditis is elevated troponin with reduced LV function (manage as myocarditis with activity restriction).
- First-line therapy for idiopathic/viral pericarditis is NSAID (e.g., ibuprofen) plus colchicine to reduce recurrence; common trap is giving corticosteroids up front — reserve for autoimmune/uremic/pericarditis refractory to NSAID/colchicine or when NSAIDs contraindicated.
- Cardiac tamponade is suggested by hypotension, elevated JVP, tachycardia, pulsus paradoxus >10 mm Hg, and echo RA/RV diastolic collapse; priority rule is urgent pericardiocentesis for hemodynamic compromise rather than waiting on further imaging.
- In suspected aortic dissection (sudden tearing pain, pulse deficit, widened mediastinum), avoid anticoagulation/thrombolysis for presumed MI — this is a lethal trap; obtain emergent CTA/TEE and control BP/HR first.
- Constrictive pericarditis clues include right-sided failure with Kussmaul sign, pericardial knock, and ventricular interdependence (discordant LV/RV systolic pressures with respiration); key differentiator from restrictive cardiomyopathy is respiratory variation in mitral inflow and hepatic vein diastolic flow reversal.
- Pericardial effusions require etiology-based workup (malignancy, TB, uremia, hypothyroidism) and monitoring for progression; red flag for intervention is large effusion with tamponade physiology or suspected purulent/neoplastic effusion needing diagnostic drainage.
- Cyanotic newborn with shock/collapse — suspect ductal-dependent CHD and start prostaglandin E1 immediately; red flag is giving only oxygen/fluids while delaying PGE1.
- Fixed split S2 suggests atrial septal defect; trap is attributing a “split” that varies with respiration to ASD rather than normal physiology.
- Repaired tetralogy of Fallot with severe pulmonic regurgitation can present years later with RV dilation and ventricular arrhythmias; priority cue is progressive QRS widening (e.g., >180 ms) prompting evaluation for pulmonary valve replacement/EP risk stratification.
- Coarctation of the aorta — compare upper vs lower extremity BPs and femoral pulses; red flag is refractory hypertension in a young patient or arm–leg systolic gradient =20 mmHg.
- Bicuspid aortic valve — screen for ascending aortopathy and counsel on family screening; trap is focusing only on the valve gradient and missing progressive aortic dilation needing serial imaging.
- Eisenmenger physiology (unrepaired shunt with PAH) — avoid closing the defect once pulmonary vascular disease is established; contraindication cue is right-to-left shunting with elevated PVR where closure can precipitate RV failure.
- Acute limb ischemia is a time-critical diagnosis—the red flag is the sudden onset of pain with a pulseless, cool extremity; start IV heparin immediately unless contraindicated and obtain urgent vascular surgery/endovascular consultation.
- Suspected aortic dissection: treat first by lowering shear stress (IV beta-blocker before vasodilator)—common trap is giving hydralazine/nitroprusside without rate control, which can worsen dissection.
- Abdominal aortic aneurysm screening is ultrasound in men age 65–75 who have ever smoked; red flag for rupture is hypotension with back/abdominal pain and a pulsatile mass—do not delay definitive imaging/OR for extensive workup.
- Carotid disease: the priority rule is that symptomatic high-grade stenosis (typically 70%–99%) benefits from carotid endarterectomy if perioperative stroke/death risk is acceptable; common trap is intervening on asymptomatic moderate stenosis without optimized medical therapy.
- Venous thromboembolism: for suspected pulmonary embolism with hemodynamic instability, give immediate anticoagulation and consider systemic thrombolysis if no major bleeding risk; red flag contraindication is prior intracranial hemorrhage or active bleeding.
- Peripheral artery disease management prioritizes high-intensity statin and antiplatelet therapy plus supervised exercise for claudication; common trap is using compression stockings in suspected critical limb ischemia (rest pain/ulcer/gangrene) instead of urgent revascularization evaluation.
- Diagnose true hypertension with proper technique (seated, correct cuff, multiple readings) and confirm with home/ambulatory BP when white-coat or masked HTN is suspected—trap: escalating meds based on a single in-office reading.
- In hypertensive emergency, treat end-organ injury and lower MAP by ~20%–25% in the first hour (then to ~160/100 in 2–6 hours for most)—red flag: precipitous drops causing stroke/AKI.
- Evaluate secondary causes when onset is abrupt/early, resistant (uncontrolled on 3 meds incl. diuretic), or with clues (hypokalemia, renal bruit, episodic spells)—priority rule: screen for primary aldosteronism with aldosterone–renin ratio when unexplained hypokalemia or resistant HTN.
- Choose therapy to comorbidity and avoid contraindications—cue: ACEi/ARB contraindicated in pregnancy and bilateral renal artery stenosis; thiazides often worsen hyponatremia and gout.
- Orthostatic hypotension is a sustained fall of =20 mmHg systolic or =10 mmHg diastolic within 3 minutes of standing—common trap: measuring too late or missing medication causes (alpha-blockers, nitrates, diuretics).
- In shock or symptomatic hypotension, prioritize rapid assessment of perfusion (mental status, urine output, lactate) and treat the cause—red flag: giving beta-blockers/vasodilators before stabilizing volume/vasopressors in acute decompensation.
- Suspect massive PE when hypotension/shock accompanies acute dyspnea with RV strain; priority rule: start empiric anticoagulation if pretest probability is high and bleeding risk acceptable while definitive imaging is arranged.
- Use hemodynamics to separate etiologies of pulmonary hypertension (PH): post-capillary PH has PCWP =15 mmHg; common trap: labeling PH as “primary” without right-heart catheterization confirmation.
- In chronic thromboembolic pulmonary hypertension (CTEPH), persistent dyspnea =3 months after PE is a red flag; priority test: V/Q scan (more sensitive than CT angiography for CTEPH screening).
- In acute PE, avoid overreliance on D-dimer in high-risk patients; practical cue: use age-adjusted D-dimer (age × 10 ng/mL FEU for >50) only in low/intermediate pretest probability.
- Treat pulmonary arterial hypertension (PAH) with vasoreactivity testing only in idiopathic/heritable/drug-induced PAH; contraindication/trap: do not use calcium channel blockers without a positive vasoreactivity test.
- For acute RV failure from PH/PE, maintain RV perfusion and reduce afterload; red flag: aggressive diuresis or excessive PEEP can drop preload and worsen shock.
- Suspect infective endocarditis in persistent bacteremia (especially Staphylococcus aureus) or new murmur; ABIM trap: treating with antibiotics before obtaining at least 2–3 sets of blood cultures unless the patient is unstable.
- In atrial fibrillation with rheumatic mitral stenosis or a mechanical valve, anticoagulate with warfarin (not a DOAC); red flag is an inappropriately chosen DOAC in “valvular AF.”
- For antiphospholipid syndrome with arterial thrombosis, use warfarin with an INR target typically 2.0–3.0 (higher in selected recurrent cases); common trap is relying on a positive lupus anticoagulant to mean “bleeding risk” rather than thrombosis.
- Recognize heparin-induced thrombocytopenia when platelets fall =50% 5–10 days after heparin (or sooner with prior exposure); priority rule is to stop all heparin and start a non-heparin anticoagulant even if thrombosis is not yet proven.
- In hyperthyroidism, atrial fibrillation is common—control rate with a beta-blocker unless contraindicated (e.g., severe asthma); contraindication cue: avoid amiodarone as first-line when thyroid disease is driving the arrhythmia unless other options fail.
- In suspected aortic dissection or acute aortic syndromes associated with connective tissue disease (e.g., Marfan), prioritize heart rate control (IV beta-blocker) before vasodilators; red flag is giving hydralazine or nitroprusside first and worsening shear stress.
- On pressure–volume loops, decreased preload shifts the loop left with lower stroke volume; red flag: rising LVEDP without increased EDV points to reduced compliance (diastolic dysfunction), not volume loading.
- Know determinants of myocardial O2 demand (HR, wall stress, contractility) and that coronary perfusion occurs mainly in diastole for the LV; common trap: tachycardia can worsen ischemia even if systolic BP is unchanged.
- Use Fick: CO = VO2/(CaO2-CvO2); practical cue: an unexpectedly low mixed venous O2 saturation suggests low CO or high extraction, not primary hypoxemia.
- Understand Frank–Starling and afterload: increased afterload reduces stroke volume and increases end-systolic volume; priority rule: acute severe hypertension can drop forward output despite a normal EF.
- Know cardiac action potentials: Phase 0 upstroke is Na+ in myocytes and Ca2+ in nodal tissue; common trap: hyperkalemia reduces conduction velocity and can widen QRS before causing asystole.
- Recognize normal hemodynamic waveforms: cannon “a” waves occur with AV dissociation and prominent “v” waves with severe MR; red flag: large “y” descent suggests constrictive physiology rather than tamponade.
