You have a patient with pre-renal AKI. Which condition would you expect to find in the patient’s history?

In the context of pre-renal acute kidney injury (AKI), the focus is primarily on conditions that lead to reduced kidney perfusion, resulting in decreased blood flow to the kidneys and affecting their ability to filter waste. Pre-renal AKI is often caused by factors such as dehydration, blood loss, heart failure, or other scenarios leading to inadequate blood supply to the kidneys.

In this case, the accurate answer involves myocardial infarction. A history of myocardial infarction indicates cardiac compromise, which can lead to diminished cardiac output and subsequently reduced renal perfusion. Heart conditions, including myocardial infarction, can drastically affect the ability of the heart to pump blood effectively, consequently impacting the kidneys.

Conversely, pyelonephritis, which is an infection of the kidney, is associated with intrinsic renal causes of AKI rather than pre-renal. Bladder cancer generally does not directly affect renal perfusion and is more linked to obstructive uropathy if it causes blockage in the urinary tract. Kidney stones can lead to obstructive renal injury but typically result in post-renal AKI due to obstruction rather than pre-renal causes. Therefore, a history of myocardial infarction fits within the underlying causes that lead to pre-renal AKI due
