A 68-year-old male presents with progressive dyspnea on exertion, orthopnea, and bilateral
lower extremity edema. Echocardiogram reveals an ejection fraction of 35%. Which medication
class should be initiated first-line for heart failure with reduced ejection fraction?
A) Calcium channel blockers
B) ACE inhibitors
C) Beta-blockers
D) Diuretics
Answer: B ✓
Rationale: ACE inhibitors are first-line therapy for HFrEF as they reduce mortality and
morbidity by decreasing afterload and preventing ventricular remodeling. Beta-blockers are
also important but typically added after ACE inhibitor initiation. Diuretics manage symptoms
but don't improve mortality. Calcium channel blockers are generally avoided in HFrEF.
A 72-year-old female with atrial fibrillation has a CHA2DS2-VASc score of 4. She asks about
anticoagulation options. Which factor would contraindicate the use of direct oral
anticoagulants (DOACs)?
A) Age over 70
B) Creatinine clearance of 25 mL/min
C) History of hypertension
D) Previous stroke
Answer: B ✓
,Rationale: DOACs require adequate renal function for clearance. A creatinine clearance below
30 mL/min is generally a contraindication for most DOACs. Warfarin would be preferred in
severe renal impairment. Age, hypertension, and previous stroke are indications for
anticoagulation, not contraindications to DOACs.
During a routine examination, a 55-year-old male is found to have a blood pressure of 168/92
mmHg on three separate visits. He has no other cardiovascular risk factors. According to
current guidelines, what is the most appropriate initial management?
A) Immediate initiation of two antihypertensive medications
B) Lifestyle modifications alone for 3-6 months
C) Single antihypertensive medication plus lifestyle modifications
D) Referral to cardiology before treatment
Answer: C ✓
Rationale: For stage 2 hypertension (≥160/100), current guidelines recommend initiating
pharmacologic therapy along with lifestyle modifications. Stage 1 hypertension might allow for
lifestyle modifications alone initially, but stage 2 requires medication. Two medications may be
considered but single agent initiation is appropriate. Cardiology referral is not necessary for
uncomplicated hypertension.
A 65-year-old female presents with intermittent claudication after walking two blocks.
Physical examination reveals diminished pulses in the lower extremities and cool feet. Ankle-
brachial index is 0.65. What is the most appropriate next step in management?
A) Immediate angiography
B) Supervised exercise therapy and smoking cessation
C) Surgical bypass
D) Anticoagulation with warfarin
Answer: B ✓
Rationale: Supervised exercise therapy is first-line treatment for intermittent claudication and
has been shown to improve walking distance. Smoking cessation is critical. Angiography and
surgical intervention are reserved for critical limb ischemia or failed conservative
management. Antiplatelet therapy (not anticoagulation) is indicated for PAD.
A patient with known coronary artery disease presents with new-onset chest pain. The ECG
shows ST-segment elevation in leads II, III, and aVF. Which coronary artery is most likely
occluded?
A) Left anterior descending artery
,B) Left circumflex artery
C) Right coronary artery
D) Left main coronary artery
Answer: C ✓
Rationale: ST elevation in leads II, III, and aVF indicates an inferior wall myocardial infarction,
which is typically caused by right coronary artery occlusion. LAD occlusion causes anterior MI
(leads V1-V4). LCx occlusion causes lateral MI (leads I, aVL, V5-V6). Left main occlusion
causes widespread changes.
A 70-year-old male with heart failure is being treated with furosemide, lisinopril, and
metoprolol. He presents with fatigue and muscle weakness. Laboratory studies reveal
potassium of 5.8 mEq/L and creatinine of 2.1 mg/dL (baseline 1.2). What is the most appropriate
action?
A) Increase furosemide dose
B) Hold lisinopril and recheck labs
C) Add spironolactone
D) Continue current regimen
Answer: B ✓
Rationale: The patient has hyperkalemia and worsening renal function, likely due to ACE
inhibitor effect. Lisinopril should be held temporarily while monitoring renal function and
potassium. Increasing furosemide might help potassium but doesn't address the underlying
issue. Spironolactone would worsen hyperkalemia.
Which finding on physical examination is most specific for cardiac tamponade?
A) Pulsus paradoxus
B) Beck's triad
C) Kussmaul's sign
D) Hepatojugular reflux
Answer: B ✓
Rationale: Beck's triad (hypotension, jugular venous distention, and muffled heart sounds) is
classic for cardiac tamponade. Pulsus paradoxus can occur in tamponade but also in asthma
and COPD. Kussmaul's sign (increased JVP with inspiration) is seen in constrictive pericarditis.
Hepatojugular reflux indicates right heart failure.
, A 60-year-old female presents with palpitations. ECG shows narrow complex tachycardia at
180 bpm with no visible P waves. Vagal maneuvers fail to terminate the rhythm. What is the
most appropriate next step?
A) Synchronized cardioversion
B) Adenosine 6 mg IV push
C) Amiodarone infusion
D) Defibrillation
Answer: B ✓
Rationale: This presentation is consistent with AV nodal reentrant tachycardia (AVNRT).
Adenosine is first-line pharmacologic therapy after failed vagal maneuvers. It briefly blocks AV
node conduction, terminating the reentrant circuit. Cardioversion is reserved for unstable
patients. Amiodarone is used for ventricular arrhythmias. Defibrillation is for pulseless VT/VF.
A patient with mechanical mitral valve replacement requires anticoagulation. Which statement
regarding anticoagulation management is correct?
A) Target INR should be 2.0-3.0
B) DOACs are acceptable alternatives to warfarin
C) Target INR should be 2.5-3.5
D) Aspirin alone is sufficient
Answer: C ✓
Rationale: Mechanical mitral valves require higher intensity anticoagulation with target INR
2.5-3.5 due to higher thrombotic risk compared to aortic valves. DOACs are contraindicated in
mechanical valves. Aspirin alone is insufficient. Aortic mechanical valves typically target INR
2.0-3.0.
A 75-year-old male presents with syncope. Physical examination reveals a harsh systolic
murmur at the right upper sternal border that radiates to the carotids. The murmur increases
with squatting. What is the most likely diagnosis?
A) Aortic stenosis
B) Hypertrophic cardiomyopathy
C) Mitral regurgitation
D) Pulmonic stenosis
Answer: A ✓
