Zorluk: KolayMedical History Evaluation

A 68-year-old man with a history of ischemic cardiomyopathy (ejection fraction 35%) and osteoarthritis presents to the clinic with progressive shortness of breath and bilateral lower extremity edema over the past week. He states he has been taking his prescribed furosemide, lisinopril, and carvedilol daily. His blood pressure is 155/92 mmHg, and his heart rate is 78/min. Physical examination reveals jugular venous distention and bilateral crackles at the lung bases. When obtaining a targeted medical history to evaluate the cause of his decompensation, which of the following patient reports would be most directly responsible for his current presentation? (Select all that apply)

  1. Initiation of over-the-counter naproxen twice daily for knee painCevap
  2. Increased consumption of canned soups and frozen mealsCevap
  3. C
    Omission of his prescribed atorvastatin for the past three days
  4. D
    Addition of a daily 81 mg aspirin tablet for cardiovascular health
  5. E
    Completion of a three-day course of azithromycin for a mild upper respiratory infection

Cevap

The correct historical findings are the initiation of over-the-counter naproxen and the increased consumption of canned soups and frozen meals.
The correct options identify the two most common and direct triggers for acute decompensated heart failure in an otherwise stable patient: dietary indiscretion (excessive sodium from processed foods) and the initiation of nonsteroidal anti-inflammatory drugs (NSAIDs like naproxen). NSAIDs inhibit renal prostaglandins, which are necessary to maintain afferent arteriolar vasodilation and renal perfusion in the setting of decreased cardiac output. This inhibition leads to significant sodium and water retention. Similarly, high dietary sodium directly increases intravascular volume, overwhelming the left ventricle and leading to pulmonary and systemic congestion.

Adım Adım Çözüm

1
Analyze the patient's clinical presentation and vital signs.
The patient is experiencing acute decompensated heart failure, evidenced by progressive shortness of breath, lower extremity edema, elevated blood pressure, jugular venous distention, and pulmonary crackles.
Establishing the primary physiological problem (volume overload) is necessary to determine the triggering event.
2
Evaluate the provided historical elements for their physiological impact on fluid balance.
Naproxen use causes renal sodium retention through prostaglandin inhibition, and excessive dietary sodium from canned foods directly increases intravascular volume.
Identifying factors that increase fluid retention explains the acute decompensation despite adherence to baseline diuretic and antihypertensive therapies.

Anahtar Kavram

Identifying historical triggers for acute decompensated heart failure, specifically medication non-adherence, dietary indiscretion, and the introduction of contraindicated medications like NSAIDs.
