Question 1
Q: What is the primary function of the coronary arteries?
A: To supply blood to the heart muscle (myocardium).
Rationale: The coronary arteries branch off from the aorta and deliver oxygen-rich blood to
the heart muscle, ensuring it receives the nutrients and oxygen needed for effective
contraction and function.
Question 2
Q: Which cardiac biomarker is most commonly used to diagnose myocardial infarction (heart
attack)?
A: Troponin.
Rationale: Troponin is a protein released into the bloodstream when the heart muscle is
damaged. Elevated troponin levels are a strong indicator of myocardial injury, making it a
key biomarker in diagnosing heart attacks.
Question 3
Q: What is the mechanism of action of beta-blockers in treating cardiovascular conditions?
A: They block beta-adrenergic receptors, decreasing heart rate and contractility.
Rationale: Beta-blockers reduce the effects of adrenaline on the heart, leading to lower heart
rates and decreased cardiac output. This helps manage conditions like hypertension,
arrhythmias, and heart failure.
Question 4
Q: What is the most common cause of congestive heart failure (CHF)?
A: Coronary artery disease (CAD).
,Rationale: CAD, characterized by narrowed or blocked coronary arteries, reduces blood flow
to the heart muscle, leading to ischemia and eventually heart failure. Other causes include
hypertension, valvular heart disease, and cardiomyopathy.
Question 5
Q: In an electrocardiogram (ECG), what does the QRS complex represent?
A: Ventricular depolarization.
Rationale: The QRS complex reflects the electrical activity that triggers ventricular
contraction, indicating that the ventricles are depolarizing and preparing to pump blood to the
lungs and the rest of the body.
Question 6
Q: What is the normal range for adult resting heart rate?
A: 60 to 100 beats per minute.
Rationale: A resting heart rate within this range is considered normal for adults. Rates below
or above this range may indicate bradycardia or tachycardia, respectively, which can be signs
of underlying health issues.
Question 7
Q: What is the primary purpose of an angioplasty?
A: To open narrowed or blocked coronary arteries.
Rationale: Angioplasty involves using a balloon catheter to widen the artery and restore
blood flow, often accompanied by the placement of a stent to keep the artery open, improving
oxygen delivery to the heart muscle.
Question 8
Q: Which condition is characterized by the accumulation of fluid in the lungs due to heart
failure?
A: Pulmonary congestion.
,Rationale: Pulmonary congestion occurs when the heart cannot effectively pump blood,
causing increased pressure in the pulmonary circulation. This leads to fluid leakage into the
lungs, resulting in symptoms like shortness of breath and coughing.
Question 9
Q: What is the primary treatment for atrial fibrillation to prevent stroke?
A: Anticoagulants.
Rationale: Anticoagulants reduce the risk of blood clots forming in the atria during atrial
fibrillation. This is crucial in preventing strokes, which can occur if a clot travels to the brain.
Question 10
Q: What is a common side effect of ACE inhibitors?
A: Cough.
Rationale: ACE inhibitors can cause a persistent dry cough in some patients due to the
accumulation of bradykinin, a peptide that is normally broken down by angiotensin-
converting enzyme (ACE). This side effect can lead to discontinuation of the medication.
Question 11
Q: What is the primary purpose of a Holter monitor?
A: To continuously record the heart's electrical activity over 24 to 48 hours.
Rationale: A Holter monitor allows for the assessment of heart rhythm abnormalities that
may not be captured during a standard ECG, helping diagnose conditions like arrhythmias or
syncope.
Question 12
Q: What is the main characteristic of aortic stenosis?
A: Narrowing of the aortic valve, which obstructs blood flow from the left ventricle.
Rationale: Aortic stenosis leads to increased pressure in the left ventricle and can cause
symptoms such as chest pain, syncope, and heart failure due to the heart's struggle to pump
blood efficiently.
, Question 13
Q: What is the role of diuretics in managing heart failure?
A: To reduce fluid overload and decrease blood pressure.
Rationale: Diuretics promote the excretion of sodium and water through urine, helping to
alleviate symptoms of congestion (e.g., edema and pulmonary congestion) associated with
heart failure.
Question 14
Q: What does a prolonged QT interval on an ECG indicate?
A: Increased risk of life-threatening arrhythmias.
Rationale: A prolonged QT interval can lead to torsades de pointes, a type of ventricular
tachycardia, and is associated with various factors, including electrolyte imbalances and
certain medications.
Question 15
Q: What is the most common symptom of myocardial ischemia?
A: Chest pain or discomfort (angina).
Rationale: Angina occurs when the heart muscle doesn't receive enough oxygen due to
reduced blood flow, often triggered by physical activity or stress. It may also present as
pressure, heaviness, or squeezing in the chest.
Question 16
Q: What is the primary cause of dilated cardiomyopathy?
A: It is often idiopathic, but can be associated with factors like ischemic heart disease,
alcohol abuse, or viral infections.
Rationale: Dilated cardiomyopathy leads to enlarged heart chambers and decreased
contractility, impairing the heart's ability to pump blood effectively. Various factors can
contribute to its development.
