1A 62-year-old man with hypertension and dyslipidemia presents with a 2-hour history of retrosternal chest tightness occurring at rest. Vital signs show blood pressure 138/84 mmHg, heart rate 78 bpm, and oxygen saturation 98% on room air. The 12-lead ECG demonstrates 1.5 mm horizontal ST-segment depression in leads V4 to V6 with T-wave inversion. High-sensitivity cardiac troponin T is elevated at 145 ng/L (reference < 14 ng/L). Along with loading doses of aspirin and heparin, which oral P2Y12 inhibitor is most appropriate as part of dual antiplatelet therapy in this patient who has no history of stroke or transient ischemic attack?
2A 68-year-old woman with ischemic cardiomyopathy has persistent exertional breathlessness corresponding to NYHA functional class II. Transthoracic echocardiography reveals a left ventricular ejection fraction of 30%. Her current medical regimen consists of enalapril 10 mg twice daily, carvedilol 25 mg twice daily, and furosemide 40 mg once daily. Her blood pressure is 122/74 mmHg, heart rate is 68 bpm, eGFR is 52 mL/min/1.73m2, and serum potassium is 4.3 mmol/L. Which pharmacological agent should be initiated next to reduce heart failure hospitalization and cardiovascular mortality?
3A 72-year-old woman with well-controlled primary hypertension is found to have an irregularly irregular pulse during a routine clinic visit. An ECG confirms atrial fibrillation with a ventricular response rate of 88 bpm. She has no history of stroke, transient ischemic attack, diabetes mellitus, heart failure, or peripheral vascular disease. Transthoracic echocardiography shows normal left ventricular systolic function with mild left atrial enlargement. What is the most appropriate long-term stroke prevention strategy for this patient?
4A 48-year-old man who underwent mechanical aortic valve replacement three years ago presents with a 3-week history of low-grade fever, night sweats, fatigue, and weight loss. On examination, temperature is 38.2 C, pulse is 92 bpm, and a new early diastolic murmur is heard along the left sternal border. Subungual splinter hemorrhages are visible on the right hand. Blood cultures drawn on admission are pending. Which diagnostic investigation has the highest sensitivity for detecting prosthetic valve endocarditis and peri-annular abscess?
5A 54-year-old man with type 2 diabetes mellitus and a prior myocardial infarction 2 years ago attends the outpatient medical clinic. His current medications are metformin 1000 mg twice daily, atorvastatin 40 mg, and ramipril 10 mg. His BMI is 31 kg/m2, blood pressure is 128/78 mmHg, and laboratory tests show HbA1c 8.4% (target < 7.0%) and eGFR 78 mL/min/1.73m2. Which medication is the most appropriate next addition to achieve glycemic control while conferring proven cardiovascular risk reduction?
6A 42-year-old woman presents to primary care complaining of progressive generalized fatigue, 4 kg weight gain over 3 months, cold intolerance, and dry coarse skin. Physical examination reveals a non-tender, diffusely enlarged thyroid gland, delayed deep tendon reflexes, and a pulse of 56 bpm. Laboratory evaluation reveals serum thyroid-stimulating hormone (TSH) of 16.4 mIU/L (reference 0.4–4.0 mIU/L) and free thyroxine (free T4) of 7.2 pmol/L (reference 10–22 pmol/L). What is the most appropriate initial management?
7A 46-year-old man presents with persistent hypertension resistant to three antihypertensive agents (amlodipine 10 mg, valsartan 160 mg, and hydrochlorothiazide 25 mg daily). Routine blood testing reveals a serum potassium level of 2.9 mmol/L (reference 3.5–5.0 mmol/L) without diuretic abuse. Which initial screening test is recommended to evaluate for primary aldosteronism?
8A 38-year-old woman presents with persistent anorexia, progressive weakness, dizziness upon standing, and hyperpigmentation of the palmar creases and buccal mucosa. Blood pressure is 94/60 mmHg supine and drops to 78/50 mmHg standing. Serum sodium is 129 mmol/L and serum potassium is 5.4 mmol/L. Which diagnostic investigation is the gold standard for establishing the diagnosis of primary adrenal insufficiency?
9A 70-year-old man who takes ramipril and diclofenac for degenerative osteoarthritis develops acute gastroenteritis with 3 days of severe watery diarrhea and vomiting. On presentation, mucous membranes are dry, skin turgor is poor, blood pressure is 92/58 mmHg, and heart rate is 104 bpm. Serum creatinine has increased from a baseline of 85 umol/L to 240 umol/L. Urinalysis shows no proteinuria, hematuria, or casts, and the fractional excretion of sodium (FENa) is calculated at 0.4%. What is the primary underlying mechanism of this acute kidney injury?
10A 34-year-old man presents with generalized bilateral lower extremity edema, facial puffiness, and foamy urine developing over 4 weeks. Examination shows 3+ pitting edema to the mid-thighs and periorbital swelling. A 24-hour urine collection reveals 5.6 g of protein. Serum albumin is 21 g/L and total cholesterol is 8.6 mmol/L. Renal function is preserved with eGFR 98 mL/min/1.73m2. Serologies for ANA, hepatitis B, hepatitis C, and HIV are negative. Circulating anti-phospholipase A2 receptor (anti-PLA2R) autoantibodies are strongly positive. What is the most likely diagnosis?
