Cardiovascular System (CVS) Module 3rd Year

📝 Step 7 — KMU Past Papers & Exam Learning

This section contains KMU-style exam questions and past-paper-oriented concepts designed to strengthen integrated clinical reasoning. Focus on understanding the disease mechanism, diagnostic clue, drug logic, organism link, prevention point, forensic relevance and explanation behind each answer.

🎯 How to Study KMU Exam Questions

  • Read the clinical stem carefully and identify the main problem.
  • Look for the key clue: symptom, lab finding, organism, drug, risk factor or forensic detail.
  • Think about the answer before looking at the explanation.
  • Understand why the correct option is correct and why the other options are wrong.
  • Revise difficult questions again with the related mechanism from Step 2 and Step 6.

MCQ 1

Question:
A 48-year-old man with central obesity, hypertension and low HDL has no chest pain. His physician calculates his 10-year probability of cardiovascular events before deciding treatment intensity. Which principle is being applied?

Options:
Assessment of total cardiovascular risk
Confirmation of acute myocardial injury
Diagnosis of familial hypercholesterolemia
Measurement of coronary artery stenosis
Detection of unstable plaque rupture

Correct Answer:
Assessment of total cardiovascular risk

Explanation:
CVD risk stratification estimates future event probability using multiple risk factors, not symptoms alone.

MCQ 2

Question:
A coronary artery plaque shows many macrophages, extracellular lipid, cholesterol clefts and a thin fibrous covering. Which outcome is most strongly suggested by this morphology?

Options:
Gradual venous dilatation
Sudden thrombotic occlusion
Reversible endothelial repair
Primary myocardial infection
Congenital valve obstruction

Correct Answer:
Sudden thrombotic occlusion

Explanation:
A thin-cap lipid-rich plaque is vulnerable to rupture, causing thrombosis and acute coronary syndrome.

MCQ 3

Question:
A 36-year-old man has very high LDL-C, tendon xanthomas and a strong family history of premature coronary death. Which dyslipidemia pattern best explains his presentation?

Options:
Isolated low HDL syndrome
Severe postprandial chylomicronemia
Drug-induced hyperuricemia
Secondary hypertriglyceridemia
Familial hypercholesterolemia

Correct Answer:
Familial hypercholesterolemia

Explanation:
Marked LDL elevation with tendon xanthomas and premature CAD suggests familial hypercholesterolemia.

MCQ 4

Question:
A patient started on simvastatin is also prescribed erythromycin. Which mechanism best explains the increased risk of muscle toxicity?

Options:
Reduced hepatic metabolism of statin
Increased renal excretion of statin
Reduced intestinal cholesterol uptake
Enhanced bile acid binding in gut
Increased HDL particle formation

Correct Answer:
Reduced hepatic metabolism of statin

Explanation:
Macrolides may inhibit CYP3A4 metabolism of some statins, increasing statin levels and myopathy risk.

MCQ 5

Question:
A 58-year-old diabetic smoker has LDL-C of 150 mg/dL and no previous myocardial infarction. Which outpatient strategy best addresses his future coronary risk?

Options:
Only reassurance because symptoms are absent
Short course therapy until LDL becomes normal
Risk-based lipid control with lifestyle change
Immediate thrombolysis before further testing
Avoidance of blood pressure assessment

Correct Answer:
Risk-based lipid control with lifestyle change

Explanation:
High-risk asymptomatic patients need primary prevention based on total CVD risk, not symptom presence alone.

MCQ 6

Question:
A lipid-lowering drug lowers triglycerides by activating PPAR-alpha and increasing lipoprotein lipase activity. Which serum lipid change is expected?

Options:
Marked fall in triglycerides
Marked rise in chylomicrons
Marked rise in LDL cholesterol
Marked fall in HDL cholesterol
Marked rise in bile acids

Correct Answer:
Marked fall in triglycerides

Explanation:
Fibrates activate PPAR-alpha, increasing triglyceride-rich lipoprotein clearance.

MCQ 7

Question:
Atherosclerosis is described as a chronic inflammatory disease of the arterial intima. Which cell is central in converting retained modified lipoprotein into fatty streak formation?

Options:
Macrophage
Eosinophil
Basophil
Megakaryocyte
Osteoblast

Correct Answer:
Macrophage

Explanation:
Macrophages ingest oxidized LDL and become foam cells, producing early fatty streaks.

MCQ 8

Question:
A patient with hypercholesterolemia is given cholestyramine. He is also taking warfarin and levothyroxine. What prescribing advice is most appropriate?

Options:
Stop all antihypertensive drugs
Give all tablets together with meals
Avoid checking serum lipid levels
Separate dosing of interacting drugs
Combine routinely with gemfibrozil

Correct Answer:
Separate dosing of interacting drugs

Explanation:
Bile acid sequestrants bind many drugs in the gut and reduce their absorption.

MCQ 9

Question:
A 60-year-old man with previous myocardial infarction asks why he must continue lipid-lowering therapy despite feeling well. Which response best explains the rationale?

Options:
It treats acute chest pain immediately
It reduces recurrence of vascular events
It confirms the diagnosis of stable angina
It reverses all established arterial plaques
It replaces the need for BP control

Correct Answer:
It reduces recurrence of vascular events

Explanation:
After established CAD, lipid-lowering therapy is part of secondary prevention to reduce recurrence and mortality.

MCQ 10

Question:
A patient has raised VLDL, raised triglycerides, low HDL and central obesity. Which associated clinical state most commonly fits this pattern?

Options:
Acute rheumatic fever
Severe iron deficiency
Insulin resistance
Bacterial endocarditis
Congenital heart block

Correct Answer:
Insulin resistance

Explanation:
High TG, low HDL and central obesity are features of atherogenic dyslipidemia in metabolic syndrome.

MCQ 11

Question:
A statin reduces plasma LDL mainly after hepatic cholesterol synthesis decreases. What is the next key hepatic response?

Options:
Increased LDL receptor expression
Increased chylomicron secretion
Increased bile pigment formation
Reduced albumin synthesis
Reduced VLDL clearance

Correct Answer:
Increased LDL receptor expression

Explanation:
Reduced hepatic cholesterol upregulates LDL receptors, increasing LDL clearance from plasma.

MCQ 12

Question:
A coronary plaque becomes complicated by surface ulceration, hemorrhage and superimposed thrombus. Which clinical syndrome is most directly linked to this change?

Options:
Chronic stable exertional angina only
Asymptomatic fatty streak formation
Slow compensatory vessel widening
Acute coronary syndrome
Benign flow murmur

Correct Answer:
Acute coronary syndrome

Explanation:
Plaque disruption with thrombosis is the pathological basis of unstable angina and myocardial infarction.

MCQ 13

Question:
A patient with high LDL cannot tolerate a statin. Ezetimibe is considered. Which site of action best matches this drug?

Options:
Pancreatic beta cell membrane
Intestinal brush border
Platelet cyclooxygenase enzyme
Adrenal steroid pathway
Renal collecting duct

Correct Answer:
Intestinal brush border

Explanation:
Ezetimibe inhibits NPC1L1-mediated cholesterol absorption at the intestinal brush border.

MCQ 14

Question:
A 50-year-old woman with gout and poorly controlled diabetes is being evaluated for lipid therapy. Which lipid-lowering drug requires special caution because it can worsen both conditions?

Options:
Ezetimibe
Cholestyramine
Atorvastatin
Niacin
Colesevelam

Correct Answer:
Niacin

Explanation:
Niacin can cause hyperuricemia and hyperglycemia, so caution is needed in gout and diabetes.

A patient’s plasma contains a lipoprotein mainly responsible for transporting dietary triglycerides from intestine after a fatty meal. Which particle is being described?

Options:
Low-density lipoprotein
Chylomicron
High-density lipoprotein
Intermediate-density lipoprotein
Lipoprotein(a)

Correct Answer:
Chylomicron

Explanation:
Chylomicrons transport dietary triglycerides from the intestine to tissues.

MCQ 17

Question:
A 62-year-old man with hypertension has concentric left ventricular strain and later develops stroke. Which explanation best supports hypertension as a public-health priority?

Options:
It affects only coronary arteries
It is unrelated to lifestyle change
It prevents arterial endothelial injury
It has no role in renal disease
It causes multiple vascular outcomes

Correct Answer:
It causes multiple vascular outcomes

Explanation:
Hypertension increases risk of coronary disease, stroke, heart failure and renal disease, making control a public-health priority.

MCQ 18

Question:
A patient with high LDL begins a statin. Which adverse effect should prompt urgent evaluation if severe muscle pain and dark urine develop?

Options:
Rhabdomyolysis
Bronchoconstriction
Aplastic anemia
Ototoxicity

MCQ 20

Question:
A patient with established coronary artery disease is advised diet modification, smoking cessation, BP control, diabetes control and statin therapy. Which prevention level best fits this package?

Options:
Primordial prevention
Primary prevention
Screening only
Secondary prevention
Health promotion only

Correct Answer:
Secondary prevention

Explanation:
In established CAD, these measures prevent recurrent events and complications.

📌 Important Exam Strategy

KMU examinations often test integrated understanding rather than isolated facts. For 3rd year, focus on linking pathology, pharmacology, microbiology, community medicine, forensic medicine and clinical presentation in the same question stem.

✅ Revision Tip

If you can explain the clinical clue, underlying mechanism, correct answer and reason for excluding other options without looking at notes, your concept is strong.
