300 QUESTIONS AND ANSWERS
1. Q: What is adults' most common cause of heart failure? A: Coronary artery
disease (CAD) is the most common cause, accounting for approximately 60-
70% of heart failure cases.
2. Q: What are the classic signs and symptoms of left-sided heart failure? A:
Dyspnea, orthopnea, paroxysmal nocturnal dyspnea (PND), fatigue, and
pulmonary congestion with crackles on auscultation.
3. Q: What medication class is considered first-line treatment for heart failure
with reduced ejection fraction? A: ACE inhibitors (or ARBs if ACE inhibitors
are contraindicated) along with beta-blockers.
4. Q: What is the normal ejection fraction range? A: 55-70% is considered
normal ejection fraction.
5. Q: What dietary restriction is most important for patients with heart failure?
A: Sodium restriction (typically 2-3 grams per day) to prevent fluid retention.
6. Q: What is the most serious complication of atrial fibrillation? A: Stroke due
to thromboembolic events from blood clots forming in the atria.
7. Q: What is the target INR range for patients on warfarin for atrial
fibrillation? A: 2.0-3.0 for most patients with atrial fibrillation.
8. Q: What are the modifiable risk factors for coronary artery disease? A:
Smoking, hypertension, diabetes, dyslipidemia, obesity, physical inactivity, and
poor diet.
9. Q: What is the gold standard diagnostic test for coronary artery disease? A:
Cardiac catheterization (coronary angiography).
10. Q: What are the classic symptoms of myocardial infarction? A: Chest
pain/pressure, shortness of breath, nausea, vomiting, diaphoresis, and radiation
of pain to arm, jaw, or back.
,11. Q: What is the time frame for administering thrombolytic therapy in
STEMI? A: Within 12 hours of symptom onset, ideally within 30 minutes of
arrival (door-to-needle time).
12. Q: What are the contraindications for thrombolytic therapy? A: Active
bleeding, recent surgery, history of hemorrhagic stroke, severe hypertension
(>180/110), and pregnancy.
13. Q: What is the difference between unstable angina and NSTEMI? A:
NSTEMI shows cardiac enzyme elevation (troponin), while unstable angina
does not show enzyme elevation.
14. Q: What is Prinzmetal's (variant) angina? A: Chest pain caused by coronary
artery spasm, often occurring at rest and typically in the early morning hours.
15. Q: What is the most common site for myocardial infarction? A: The left
anterior descending (LAD) artery territory, affecting the anterior wall of the left
ventricle.
16. Q: What are the stages of hypertension according to AHA guidelines? A:
Normal (<120/80), Elevated (120-129/<80), Stage 1 (130-139/80-89), Stage 2
(≥140/90), Crisis (>180/120).
17. Q: What is malignant hypertension? A: Severe hypertension (usually
>180/120) with evidence of end-organ damage, requiring immediate treatment.
18. Q: What are the first-line antihypertensive medications? A: ACE inhibitors,
ARBs, calcium channel blockers, and thiazide diuretics.
19. Q: What is white coat hypertension? A: Elevated blood pressure readings in
clinical settings but normal readings at home or with ambulatory monitoring.
20. Q: What are the complications of untreated hypertension? A: Stroke,
myocardial infarction, heart failure, kidney disease, retinopathy, and peripheral
arterial disease.
21. Q: What is the most common type of cardiomyopathy? A: Dilated
cardiomyopathy, characterized by enlarged heart chambers and reduced
contractility.
22. Q: What is hypertrophic cardiomyopathy? A: A genetic condition causing
thickening of the heart muscle, particularly the interventricular septum.
23. Q: What is restrictive cardiomyopathy? A: A condition where the heart
muscle becomes rigid and less compliant, impairing ventricular filling.
, 24. Q: What are the classic findings in cardiac tamponade? A: Beck's triad:
elevated JVP, muffled heart sounds, and hypotension, plus pulsus paradoxus.
25. Q: What is pulsus paradoxus? A: A drop in systolic blood pressure >10
mmHg during inspiration, seen in cardiac tamponade and severe asthma.
26. Q: What are the signs of right-sided heart failure? A: Peripheral edema,
ascites, hepatomegaly, jugular venous distension, and weight gain.
27. Q: What is the New York Heart Association (NYHA) functional
classification? A: Class I (no symptoms), Class II (slight limitation), Class III
(marked limitation), Class IV (symptoms at rest).
28. Q: What is the mechanism of action of digoxin? A: Inhibits sodium-
potassium ATPase pump, increasing intracellular calcium and improving
cardiac contractility.
29. Q: What are the signs of digoxin toxicity? A: Nausea, vomiting, visual
disturbances (yellow-green halos), bradycardia, and various arrhythmias.
30. Q: What electrolyte imbalance predisposes to digoxin toxicity? A:
Hypokalemia increases the risk of digoxin toxicity.
31. Q: What is the most common cause of sudden cardiac death? A: Ventricular
fibrillation, often secondary to coronary artery disease.
32. Q: What is the treatment for ventricular fibrillation? A: Immediate
defibrillation with CPR and advanced cardiac life support (ACLS) protocols.
33. Q: What is torsades de pointes? A: A polymorphic ventricular tachycardia
associated with prolonged QT interval.
34. Q: What medications can prolong QT interval? A: Antiarrhythmics
(quinidine, sotalol), antibiotics (fluoroquinolones), antipsychotics, and tricyclic
antidepressants.
35. Q: What is the treatment for bradycardia with hemodynamic compromise?
A: Atropine 0.5-1 mg IV, and if ineffective, transcutaneous pacing or
dopamine/epinephrine infusion.
36. Q: What are the indications for permanent pacemaker insertion? A:
Symptomatic bradycardia, complete heart block, sick sinus syndrome, and
certain types of heart failure.
37. Q: What is the difference between first, second, and third-degree heart
block? A: First-degree: prolonged PR interval; Second-degree: some P waves
don't conduct; Third-degree: complete AV dissociation.
