Vital signs show BP 128/82 mmHg, HR 102 bpm, RR 18/min, and SpO2 98% on room air. She denies chest pain or recent cocaine use. Echocardiography demonstrates dilated left ventricle with ejection fraction of 25%, global hypokinesis, and normal coronary arteries on angiography. Troponin is normal. Which of the following is the most likely diagnosis?
- A)Heart failure with reduced ejection fraction
- B)Constrictive pericarditis
- C)Cardiac tamponade

- E)Restrictive cardiomyopathy
