Date of Admission: Unspecified
Date of Discharge: Unspecified 

Hospital Course:
The patient, a 68-year-old female presented to the emergency department with complaints of sudden onset of shortness of breath, chest pain, orthopnea, and paroxysmal nocturnal dyspnea. The notably past medical history includes hypertension, high cholesterol, chronic kidney disease stage 3, and hereditary hemorrhagic telangiectasia (HHT). Initial vital signs and laboratory investigations confirms acute systolic heart failure with markedly elevated BNP levels. Following prompt medical management, the patient demonstrated symptomatic improvement and was started on guideline-directed medical therapy including beta-blocker, ACE inhibitor, aldosterone antagonist and an oral diuretic. Subsequent left and right heart catheterization reveals widely patent coronary vessels, elevated pulmonary capillary wedge pressure, and elevated left ventricular end-diastolic pressure. The patient continued to attend regular bevacizumab infusions with her haematologist as this was not thought to be the cause of her cardiomyopathy at the time. Unfortunately, the patient developed recurrent episodes of flash pulmonary edema deemed to be due to medication non-compliance and subsequently experienced sudden onset of chest pain and shortness of breath at home followed by ventricular fibrillation related cardiac arrest which required prolonged resuscitation attempts leading to therapeutic hypothermia, but eventually passed away 3 days later.
