Signs and symptoms of restrictive cardiomyopathy are similar to those for constrictive pericarditis. What are the tests used to differentiate between cardiomyopathy and pericarditis? (Mark all that apply.)
A) Cardiac ultrasonography
B) Pulmonary artery wedge pressure
C) Pulmonary artery systolic pressure
D) Central venous pressure
E) Echocardiography
Ans: B, C, D, E
Feedback: Signs and symptoms are similar to those for constrictive pericarditis: dyspnea, nonproductive cough, and chest pain. Echocardiography, as well as measurement of pulmonary artery systolic (PAS) pressure, pulmonary artery wedge pressure (PAWP), and central venous pressure (CVP), are used to differentiate the two conditions. Cardiac ultrasonography is not diagnostic in this scenario.
