Cardiology Practice Questions

Question 1

A 64-year-old male with coronary artery disease and hypertension presents with exertional chest pain, shortness of breath, and syncope. Examination reveals a harsh systolic murmur at the right second intercostal space radiating to the carotids. The ECG shows left ventricular hypertrophy, and the echocardiogram indicates increased left ventricular thickness and decreased valve area. Analyze and determine the diagnosis and the next step.

Accepted Answer

Aortic stenosis; surgical intervention

Answer

Mitral regurgitation; surgical repair

Answer

Heart failure; beta-blockers

Answer

Hypertrophic cardiomyopathy; calcium channel blockers

Question 2

Comment on the diagnosis.

Accepted Answer

Left bundle branch block

Answer

Right bundle branch block

Answer

Complete heart block

Answer

Accelerated idioventricular rhythm

Question 3

A 70-year-old man with diabetes, hypertension, and chronic kidney disease (eGFR 35 mL/min/1.73m²) presents with NSTEMI. Troponin is elevated at 8.5 ng/mL. ECG shows 2mm ST depression in V2-V5. GRACE score is 165 (high risk). He is hemodynamically stable. Cardiologist recommends early invasive strategy within 24 hours. Nephrologist is concerned about contrast-induced nephropathy potentially requiring dialysis. Patient is on metformin. Evaluate the management strategy integrating multiple specialist perspectives and evidence.

Accepted Answer

Proceed with angiography within 24 hours using iso-osmolar contrast and intravenous hydration, hold metformin

Answer

Perform coronary CT angiography as alternative to invasive angiography

Answer

Delay catheterization for 72 hours to optimize renal function with hydration

Answer

Prophylactic hemodialysis before and after catheterization to remove contrast

Answer

Medical management only with dual antiplatelet therapy, avoid catheterization

Question 4

What is the correct sequence of phases that follows isovolumic contraction in the cardiac cycle?

Accepted Answer

Ejection, Isovolumic relaxation

Answer

Rapid filling, Diastasis

Answer

Atrial systole, Isovolumic contraction

Answer

Diastasis, Atrial systole

Question 5

Answer

Pleuro - pericardial cyst

Answer
