what is the best strategy for the patient?

A 64-year-old woman, known to be hypertensive and on amlodipine, was diagnosed with breast cancer 6 months ago. She completed 6 cycles of chemotherapy, with the last one administered 4 weeks ago, in preparation for radical mastectomy and axillary clearance.

She presents to the cardiology clinic complaining of shortness of breath. On examination, her blood pressure is 105/80 mmHg, pulse is 90 bpm, and regular. Bibasilar crackles were noted on auscultation of her chest.

Her ECG showed non-specific ST changes in the anterior leads.

Based on this clinical presentation and the chest X-ray (CXR) shown below, what is your diagnosis?

A 24-year-old woman complains of pleuritic chest pain since two days ago.  The patient's pain is constant and has not decreased. The patient mentions the history of taking bodybuilding supplements and has complained of chronic cough for the past six months.

He did not complain of a recent cold or coryza symptoms.
