Free ITE Cardiovascular Medicine Questions and Answers — Questions and Answers
Question 1: Which of the following is a common first-line treatment for stable angina?
- Aspirin and nitrates (Correct answer)
- Beta-blockers and anticoagulants
- Calcium channel blockers and statins
- ACE inhibitors and diuretics
Correct answer: Aspirin and nitrates
Aspirin and nitrates are common first-line treatments for stable angina. Aspirin helps prevent clot formation and reduces the risk of myocardial infarction, while nitrates provide rapid relief of anginal symptoms by causing vasodilation and reducing myocardial oxygen demand. This combination addresses both symptom management and cardiovascular event prevention.
Question 2: Which diagnostic test is most appropriate for a patient presenting with chest pain and suspected acute coronary syndrome (ACS)?
- Stress echocardiography
- Coronary angiography
- High-sensitivity troponin test (Correct answer)
- CT coronary angiography
Correct answer: High-sensitivity troponin test
The high-sensitivity troponin test is the most appropriate initial diagnostic tool for a patient with chest pain and suspected acute coronary syndrome (ACS). Troponin is a cardiac biomarker released into the bloodstream when heart muscle is damaged. High-sensitivity assays allow for earlier detection of myocardial injury, aiding in rapid diagnosis and risk stratification.
Question 3: What is the most common cause of heart failure with preserved ejection fraction (HFpEF)?
- Myocardial infarction
- Systemic hypertension (Correct answer)
- Atrial fibrillation
- Dilated cardiomyopathy
Correct answer: Systemic hypertension
Systemic hypertension is the most common cause of heart failure with preserved ejection fraction (HFpEF). Chronic high blood pressure leads to left ventricular hypertrophy and stiffness, impairing the heart's ability to relax and fill properly during diastole. This results in symptoms of heart failure despite a normal ejection fraction.
Question 4: Which medication is contraindicated in a patient with acute heart failure?
- Beta-blockers (Correct answer)
- ACE inhibitors
- Diuretics
- Nitrates
Correct answer: Beta-blockers
Beta-blockers are generally contraindicated in the acute phase of decompensated heart failure. While beneficial in stable chronic heart failure, their negative inotropic effects can worsen cardiac output and precipitate cardiogenic shock in acutely unwell patients. They should typically be withheld or carefully titrated once the patient is stable.
Question 5: What is the goal LDL cholesterol level for a high-risk patient with cardiovascular disease?
- <100 mg/dL
- <70 mg/dL (Correct answer)
- <130 mg/dL
- <50 mg/dL
Correct answer: <70 mg/dL
For high-risk patients with established cardiovascular disease, the goal LDL cholesterol level is typically less than 70 mg/dL. Aggressive lowering of LDL cholesterol in this population has been shown to significantly reduce the risk of recurrent cardiovascular events. In some very high-risk cases, even lower targets may be considered.
