Click on the images above to zoom in

A 72-year-old male was admitted to the hospital after presenting with chest pain, progressive dyspnea, nausea and peripheral edema. Physical examination demonstrated adequate blood pressure levels and peripheral perfusion. Electrocardiography did not indicate any acute abnormality, and troponin levels were normal. Transthoracic echocardiography showed left ventricular ejection fraction of 42%, left ventricle segmental contractility alterations and mild systolic dysfunction. Previous history of two myocardial infarctions without ST elevation and right coronary angioplasty. Chest radiograph was performed.

Considering the previous history and the current clinical-hemodynamic repercussions, what is the most appropriate therapeutic approach?

a) Intravenous vasodilator and diuretics

25%

b) Vasodilator, diuretics, inotropic/vasopressor agents and intensive care support

25%

c) Fluid replacement and inotropic agents

25%

d) Angioplasty

Image analysis

 

Image 1 - Analysis: Chest radiograph, posteroanterior view, demonstrates radiographic features linked to pulmonary congestion, which can be graded into stages:

- Redistribution: Imaging shows enlarged cardiac area (increased cardiothoracic ratio, which corresponds to the ratio of maximal horizontal cardiac diameter to maximal horizontal thoracic diameter). It also demonstrates increased pulmonary vascular network with redistribution of the pulmonary veins, which is also known as cephalization (red arrows).

- Interstitial edema: Subtle interlobular septal thickening - Kerley B (yellow arrow) and C (purple arrows) lines.

- Alveolar edema: Bilateral pleural effusion - left (in blue) and right (in green).

 

  • Image 2 - Analysis: Chest radiograph, lateral view, demonstrates subtle septal thickening (Kerley D lines, orange arrows) and bilateral pleural effusion, highlighted in blue (left) and green (right). Non-absorbable sternal surgical sutures are marked in pink.

 

Highlights

  • - Acute decompensated heart failure is a clinical syndrome of new or worsening signs and symptoms of heart failure.

  • - The main precipitating factors include nonadherence with drugs and diet, infection, rhythm disturbances, myocardial ischemia and severe physical or emotional stress.

  • - Clinical manifestations include progressive dyspnea, peripheral edema and other symptoms of congestion.

  • - Clinical and hemodynamic presentations may vary. They can be categorized according to adequacy of peripheral perfusion (“warm” or “cold”) and the presence of congestion;

  • - The diagnosis is based on clinical investigation and supported by further testing, which should include electrocardiogram, serum troponin, chest radiograph and echocardiography. Natriuretic peptide levels may help if the diagnosis is uncertain.
