Q

A 55-year-old man presents to the emergency department with severe, progressive shortness of breath at rest over the last 12 hours. He denies any cardiac history, including MI, CHF, and known valvular heart disease. He denies any history of hypertension, hyperlipidemia, diabetes, or a family history of premature CAD, although he smokes two packs of cigarettes daily. He denies any history of chest, back, or abdominal discomfort. A recent treadmill ECG was normal, according to the patient.
• The patient appears dyspneic after moving to the examination table.
• Pulse 120 bpm.
• BP is 250/120 mm Hg.
• Respiratory rate is 45 breaths perminute.
• There is an elevated jugular venous pulse to the angle of his jaw.
• Inspiratory crackles are noted in all lung fields.
• His heart is tachycardic and regular, an S4is present, and no murmurs are audible.
• His abdomen is thin and soft; systolic and diastolic bruits are noted.
• His extremities are warm, bilateral femoral artery bruits are noted, and the femoral pulses are palpable but diminished.
• ECG shows sinus tachycardia and borderline LV hypertrophy (LVH) by voltage criteria. No acute ST segment or T-wave changes are present.
• Chest radiograph reveals a normal mediastinum with bilateral perihilar alveolar infiltrates.
Which of the following is included in the most appropriate initial management of this patient?

A

IV furosemide, sodium nitroprusside IV infusion, and O2

Q

A 78-year-old woman with CHF (EF, 25%), chronic AFib, gastroesophageal reflux disease, hypertension (HTN), hyperlipidemia, diabetes, and osteoporosis takes 12 different pills.

She wants to eliminate digoxin from her medication regimen and she wants to know why you put her on it in the first place. What is your answer?

A

29
Q

A 31-year-old woman is 28 weeks pregnant with her first child. She is relatively healthy and has had an uneventful pregnancy. Her obstetrician asked her to call you because she has had increasing difficulty breathing at night. In fact she is now using three pillows and occasionally wakes up gasping for air. In your office she appears dyspneic when speaking in full sentences. Her blood pressure is 95/65 and her pulse is 118. Lung examination is notable for crackles at both bases. Cardiac exam reveals a loud S1, and an extra sound in diastole. ECG shows deep inverted P waves in V1 and a rightward QRS axis. She has 1+ pitting edema in the lower extremities.

35
Q

A 55-year-old white man is referred for evaluation of hypertension (BP 185/95 mm Hg), discovered during a blood pressure screening at his workplace. The patient states that he is well and has not seen a physician in many years. He describes himself as “a fitness freak,” as he is an active jogger, abstains from alcohol, and limits his salt and fat intake. He denies any knowledge of hypertension, cardiovascular disease, renal disease, or diabetes mellitus. He
takes no medications regularly. Family history is significant in that his father was known to be hypertensive and died of a stroke. His older brother is being treated for hypertension.On examination, the patient appears well, with a blood pressure of 178/96 mm Hg while seated and standing. Body weight is 71 kg (157 lb), and height is 178 cm (70 in). Optic fundus examination is significant for grade II hypertensive retinopathy. The remainder of the examination is normal. Complete blood count, electrolyte panel, blood urea nitrogen level, creatinine concentration, thyroid-stimulating hormone level, and results of urinalysis are normal. Electrocardiography demonstrates normal sinus rhythm with left ventricular hypertrophy.To reduce the patient’s cardiovascular morbidity and mortality, which therapy would you prescribe?

Losartan
