Hypertension & Hypertensive Emergencies
Confirm hypertension correctly, identify secondary causes and end-organ injury, and choose safe outpatient or emergency treatment.
Module format: each study session covers what to learn, how the presentation appears clinically, investigation/management priorities, safety issues and common MCCQE traps.
Module 5 — Topic map
- Accurate office blood pressure measurement and confirmation with home/ambulatory readings
- Primary hypertension and global cardiovascular-risk assessment
- Initial lifestyle interventions and common first-line medication classes
- Hypertension with diabetes, CKD, coronary disease, heart failure and older age
- Resistant hypertension and medication/adherence review
- Secondary causes: renovascular disease, primary aldosteronism, endocrine causes, OSA, renal disease and medications/substances
- Hypertensive urgency versus hypertensive emergency
- Acute end-organ injury: encephalopathy, ACS, pulmonary edema, aortic syndrome, AKI and retinal injury
- Principles of controlled BP reduction and avoidance of overly rapid lowering when unsafe

Study Session 5.1 — Diagnosing Hypertension & Cardiovascular Risk
Focused MCCQE cardiovascular study session
Core topics & learning goals
- Use standardized office BP technique and repeat measurements.
- Understand home and ambulatory BP roles, white-coat and masked hypertension.
- Assess global cardiovascular risk and target-organ disease.
- Order targeted baseline tests and identify medication/substance contributors.
Clinical recognition & investigation
- Evaluate orthostatic BP when clinically indicated, especially in older adults.
- Look for retinopathy, CKD, LVH and vascular disease.
Management & patient-safety priorities
- Start lifestyle and pharmacotherapy based on confirmed BP and risk context.
- Use shared decision-making and adherence assessment.
MCCQE exam traps
- Do not diagnose chronic hypertension from one incidental reading unless the clinical situation is exceptional.
- Improper cuff size can significantly distort BP.
Study Session 5.2 — Chronic Hypertension Therapy & Secondary Causes
Focused MCCQE cardiovascular study session
Core topics & learning goals
- Know common first-line classes and comorbidity-driven choices.
- Recognize resistant hypertension and pseudo-resistance.
- Screen selectively for renal disease, renovascular disease, primary aldosteronism, OSA, thyroid/endocrine causes and substances.
- Understand monitoring after RAAS blockade/diuretics.
Clinical recognition & investigation
- Review adherence, NSAIDs, stimulants, decongestants, alcohol and licorice/other exposures.
- Recognize hypokalemia or abrupt severe hypertension as secondary-cause clues.
Management & patient-safety priorities
- Use combination therapy when needed and monitor potassium/renal function.
- Treat the identified secondary cause alongside BP control.
MCCQE exam traps
- Do not label resistant hypertension before confirming adherence and out-of-office BP.
- ACE inhibitors and ARBs are not used together routinely.
Study Session 5.3 — Hypertensive Emergency
Focused MCCQE cardiovascular study session
Core topics & learning goals
- Differentiate severe asymptomatic hypertension from acute hypertension-mediated organ injury.
- Recognize encephalopathy, ACS, pulmonary edema, AKI, aortic syndrome and retinal injury.
- Choose IV therapy based on the emergency phenotype.
- Understand controlled BP lowering and exceptions requiring disease-specific targets.
Clinical recognition & investigation
- Look for neurologic, cardiac, renal and aortic symptoms rather than treating the number alone.
- Use appropriate monitoring setting.
Management & patient-safety priorities
- Treat the end-organ emergency, not just the BP value.
- Avoid abrupt normalization that can cause ischemia.
MCCQE exam traps
- Severely elevated BP without acute organ injury is not automatically a hypertensive emergency.
- Aortic dissection requires particularly rapid anti-impulse therapy.
