Robert, 66, BMI 34 with stable CAD asks lifestyle advice; smokes, BP 142/86, LDL 118 on statin. What lifestyle modification would most benefit him?

Stop smoking and start Mediterranean-style diet

Increase dietary saturated fat to raise HDL

Begin high-intensity sprint training only

Avoid all exercise until repeat angiography

Explanation

This question tests knowledge of chronic coronary artery disease management, focusing on appropriate risk modification and treatment strategies. Chronic coronary disease management involves optimizing medical therapy (such as antiplatelets, statins, beta-blockers) and lifestyle modifications (diet, exercise, smoking cessation) to prevent progression and complications. In this scenario, the obese patient with stable CAD who smokes and has elevated BP and LDL requires prioritized lifestyle changes to reduce cardiovascular risk. The correct choice reflects smoking cessation and adopting a Mediterranean-style diet, which addresses major modifiable risks and aligns with evidence-based guidelines for secondary prevention. A common distractor might suggest avoiding all exercise until repeat angiography, which is unnecessary for stable disease and discourages beneficial physical activity. To help students: Encourage reviewing the latest clinical guidelines and understanding the rationale behind recommendations. Practice applying guidelines to different clinical scenarios to enhance decision-making skills.

2

Olga, 68, stable CAD, HTN, smoker, wants diet advice; LDL 92 on statin, A1c 6.1. What lifestyle modification would most benefit her?

Avoid fruits/vegetables to reduce carbohydrate intake

Start heavy weightlifting without aerobic activity

Increase sodium intake to improve exercise tolerance

Smoking cessation with pharmacotherapy and counseling

Explanation

This question tests knowledge of chronic coronary artery disease management, focusing on appropriate risk modification and treatment strategies. Chronic coronary disease management involves optimizing medical therapy (such as antiplatelets, statins, beta-blockers) and lifestyle modifications (diet, exercise, smoking cessation) to prevent progression and complications. In this scenario, the smoking patient with stable CAD, HTN, and prediabetes seeks diet advice, highlighting the need to prioritize high-impact changes. The correct choice reflects smoking cessation with pharmacotherapy and counseling, as it offers the greatest risk reduction and aligns with guidelines. A common distractor might suggest avoiding fruits and vegetables, which contradicts heart-healthy diet recommendations and limits nutritional benefits. To help students: Encourage reviewing the latest clinical guidelines and understanding the rationale behind recommendations. Practice applying guidelines to different clinical scenarios to enhance decision-making skills.

3

Paul, 73, 2 weeks post-PCI, on aspirin+clopidogrel, reports black stools and dizziness; BP 96/60. Based on symptoms, what is next best step?

Schedule elective stress test to assess stent patency

Stop all antiplatelets permanently and discharge

Evaluate for GI bleeding urgently while coordinating antiplatelet management

Reassure and continue both antiplatelets without evaluation

Explanation

This question tests knowledge of chronic coronary artery disease management, focusing on appropriate risk modification and treatment strategies. Chronic coronary disease management involves optimizing medical therapy (such as antiplatelets, statins, beta-blockers) and lifestyle modifications (diet, exercise, smoking cessation) to prevent progression and complications. In this scenario, the patient early post-PCI on DAPT presents with black stools and hypotension, suggesting possible GI bleeding. The correct choice reflects urgent evaluation for GI bleeding while coordinating antiplatelet management, aligning with guidelines for balancing bleeding and thrombotic risks. A common distractor might suggest reassuring and continuing without evaluation, which risks missing serious hemorrhage. To help students: Encourage reviewing the latest clinical guidelines and understanding the rationale behind recommendations. Practice applying guidelines to different clinical scenarios to enhance decision-making skills.

4

Nadia, 59, CAD, BMI 31, drinks sugary beverages daily; angina stable, LDL 76. What lifestyle modification would most benefit her?

Adopt no-carb diet with unlimited processed meats

Avoid dietary changes and rely on nitrates

Increase fruit juice intake for antioxidants

Replace sugary drinks with water and reduce refined carbs

Explanation

This question tests knowledge of chronic coronary artery disease management, focusing on appropriate risk modification and treatment strategies. Chronic coronary disease management involves optimizing medical therapy (such as antiplatelets, statins, beta-blockers) and lifestyle modifications (diet, exercise, smoking cessation) to prevent progression and complications. In this scenario, the obese patient with stable CAD consumes sugary beverages, needing dietary tweaks for weight and metabolic control. The correct choice reflects replacing sugary drinks with water and reducing refined carbs, which aids weight loss and aligns with guidelines. A common distractor might suggest adopting a no-carb diet with unlimited processed meats, which increases saturated fat and cardiovascular risk. To help students: Encourage reviewing the latest clinical guidelines and understanding the rationale behind recommendations. Practice applying guidelines to different clinical scenarios to enhance decision-making skills.

5

Elena, 64, stable CAD, overweight, sedentary, LDL 80 on statin; angina only climbing 2 flights. What lifestyle modification would most benefit her?

Ketogenic diet emphasizing processed meats

Avoid walking to prevent ischemia

Increase alcohol intake to improve HDL

Structured cardiac rehab-style aerobic exercise program

Explanation

This question tests knowledge of chronic coronary artery disease management, focusing on appropriate risk modification and treatment strategies. Chronic coronary disease management involves optimizing medical therapy (such as antiplatelets, statins, beta-blockers) and lifestyle modifications (diet, exercise, smoking cessation) to prevent progression and complications. In this scenario, the overweight, sedentary patient with stable CAD and exertional angina needs lifestyle interventions to improve symptoms and risk profile. The correct choice reflects a structured cardiac rehab aerobic exercise program, which enhances functional capacity and aligns with guidelines for secondary prevention. A common distractor might suggest avoiding walking to prevent ischemia, which is counterproductive and limits beneficial activity in stable disease. To help students: Encourage reviewing the latest clinical guidelines and understanding the rationale behind recommendations. Practice applying guidelines to different clinical scenarios to enhance decision-making skills.

6

Evelyn, 71, CAD, smoker, diet high in sodium; BP 150/88 despite meds, LDL 70. What lifestyle modification would most benefit her?

Increase processed foods to maintain calories

Stop all exercise to avoid BP spikes

Add herbal stimulants for weight loss

Reduce dietary sodium and follow DASH-style eating pattern

Explanation

This question tests knowledge of chronic coronary artery disease management, focusing on appropriate risk modification and treatment strategies. Chronic coronary disease management involves optimizing medical therapy (such as antiplatelets, statins, beta-blockers) and lifestyle modifications (diet, exercise, smoking cessation) to prevent progression and complications. In this scenario, the smoking patient with CAD and uncontrolled HTN on a high-sodium diet needs dietary changes to improve BP control. The correct choice reflects reducing sodium and following a DASH-style pattern, which effectively lowers BP and aligns with guidelines. A common distractor might suggest stopping all exercise, which is unnecessary and limits cardiovascular benefits. To help students: Encourage reviewing the latest clinical guidelines and understanding the rationale behind recommendations. Practice applying guidelines to different clinical scenarios to enhance decision-making skills.

7

Marisol, 57, CAD, BMI 32, prediabetes, BP 138/84 on meds; walks 10 min daily. What lifestyle modification would most benefit her?

Avoid exercise and focus on vitamin supplements

Increase moderate aerobic activity to 150 min/week

Start high-dose energy drinks before workouts

Adopt very low-sodium diet only, no activity changes
