Date	Event
Day 1	A patient with a history of coronary artery bypass surgery was referred to the emergency department with deteriorating general condition and oliguria.
Day 3	The patient was transferred to the nephrology intensive care unit for dialysis due to severe acute kidney injury.
Day 6	Acute heart failure and worsening clinical condition required emergency haemodialysis and non-invasive ventilation. A coronary angiography was performed because of elevated cardiac troponin levels and a global impairment in left ventricular systolic function with left ventricular ejection fraction (LVEF) of 20%. It revealed significant stenosis of the middle left circumflex artery (LCX) and a subtotal occlusion stenosis of the left subclavian artery prior to the origin of the left internal mammary artery (LIMA) to left anterior descending artery (LAD) graft. The patient was treated with angioplasty of the middle LCX and angioplasty of the left subclavian artery.
Day 9	Post-procedural echocardiography indicated a LVEF of 40%. Dobutamine was discontinued without complication.
Day 21	Recovery of diuresis. Discontinuation of dialysis therapy.
Day 39	The patient was discharged home on Day 39 due to marked socio-economic precarity, a lack of access to domiciliary care, and difficulties in access to rehabilitation and care services.
