What should be assessed 7 to 10 days after initiating or increasing the dose of ACE-I/ARB?

Assessing potassium, creatinine, and blood urea nitrogen (BUN) 7 to 10 days after initiating or increasing the dose of an angiotensin-converting enzyme inhibitor (ACE-I) or angiotensin receptor blocker (ARB) is crucial in managing patients with heart failure.

ACE inhibitors and ARBs can significantly affect kidney function and potassium levels. These medications can cause hyperkalemia (elevated potassium levels) and renal impairment, especially in patients who have pre-existing renal dysfunction or those taking other medications that can affect kidney function or potassium metabolism. Monitoring creatinine provides insight into the kidneys' ability to filter waste products, while BUN helps evaluate renal function and hydration status.

Regular assessment of these parameters within a week or so after a dosage change allows for timely identification of potential side effects that could lead to serious complications. This close monitoring is an integral part of safe medication management in patients receiving heart failure treatment.

While electrolyte levels and liver function tests are essential for overall assessment in different scenarios, they are not as immediately critical in the context of adjusting ACE-I/ARB therapy compared to monitoring potassium, creatinine, and BUN. Similarly, heart rate, blood pressure, body weight, and fluid status are important outcomes
