What is the ABIM Cardiovascular Disease?
The ABIM Cardiovascular Disease study guide is designed to help candidates understand the main content areas, review the most important topics, and prepare in a more focused way.
This page organizes the available topic information for the ABIM test into clear study sections so candidates can prioritize review and practice more effectively.
How this study guide is organized
Use this study guide to review the content areas, understand how the exam is structured, and identify where to spend the most study time. Candidates usually get the best results by reviewing the highest-priority domains first, then reinforcing weaker areas with practice tests.
ABIM domain sections
The sections below show the available topic coverage for this exam. Where topic percentages are available, they can help you prioritize your study time.
Arrhythmias
- 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.
Coronary Artery Disease
- 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.
Heart Failure and Cardiomyopathy
- 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.
Valvular Disease
- 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.
Pericardial Disease
- 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.
Congenital Heart Disease
- 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.
Vascular Diseases
- 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.
Systemic Hypertension and Hypotension
- 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.
Pulmonary Circulation Disorders
- 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.
Systemic Disorders Affecting the Circulatory System
- 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.
Normal Cardiovascular Anatomy and Physiology
- 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.
