Zorluk: KolayCardiovascular System

A 61-year-old man visits an outpatient clinic due to a three-week history of progressively worsening fatigue, a persistent nighttime cough, and swelling in both ankles. He has not seen a healthcare provider in several years. The patient notes that he recently started sleeping in a recliner chair because lying flat in bed makes him feel as though he is suffocating. His medical history is notable for long-standing, untreated hypertension. Vital signs show a temperature of 37.0°C (98.6°F), pulse of 96/min, respirations of 18/min, and blood pressure of 168/94 mmHg. Examination reveals 2+ pitting edema up to the mid-calves bilaterally. Cardiac auscultation demonstrates a low-frequency extra heart sound occurring shortly after S2. Pulmonary auscultation reveals fine crackles at both lung bases. Which of the following is the most appropriate initial medication to alleviate this patient's acute symptoms?

  1. FurosemideCevap
  2. B
    Ipratropium
  3. C
    Metoprolol
  4. D
    Amlodipine
  5. E
    Azithromycin

Cevap

Furosemide is the most appropriate initial therapy for acute decompensated heart failure presenting with volume overload.
The patient presents with classic signs of acute decompensated heart failure (ADHF), including orthopnea (sleeping in a recliner), lower extremity edema, bibasilar lung crackles, and an S3 gallop (low-frequency extra heart sound after S2). The immediate goal of therapy in ADHF with volume overload is to reduce central venous and pulmonary capillary wedge pressures. Intravenous loop diuretics, such as furosemide, are the first-line therapy because they provide rapid diuresis and mild venodilation, effectively alleviating both pulmonary congestion and peripheral edema.

Adım Adım Çözüm

1
Identify the primary clinical syndrome based on the patient's symptoms and physical examination findings.
The patient exhibits orthopnea, peripheral edema, an S3 gallop, and bibasilar crackles, which are classic hallmark signs of acute decompensated heart failure.
Accurate identification of the syndrome is required to differentiate cardiogenic pulmonary edema from primary pulmonary diseases like asthma, COPD, or pneumonia.
2
Determine the most appropriate initial pharmacological intervention for the identified syndrome.
A loop diuretic, such as furosemide, is the treatment of choice.
Loop diuretics rapidly reduce intravascular volume, effectively alleviating the hydrostatic pressure that causes pulmonary and systemic congestion.

Anahtar Kavram

The initial management of acute decompensated heart failure with volume overload requires rapid diuresis using a loop diuretic (e.g., furosemide) to relieve pulmonary and systemic congestion.
