BACKGROUND: Concerns about hyperkalemia limit the use of angiotensin-converting
enzyme inhibitors (ACE-I) and angiotensin receptor blockers (ARBs), but
guidelines conflict regarding potassium-monitoring protocols. We quantified
hyperkalemia monitoring and risks after ACE-I/ARB initiation and developed and
validated a hyperkalemia susceptibility score. METHODS AND RESULTS: We evaluated
69 426 new users of ACE-I/ARB therapy in the Stockholm Creatinine Measurements
(SCREAM) project with medication initiation from January 1, 2007 to December 31,
2010, and follow-up for 1 year thereafter. Three fourths (76%) of SCREAM patients
had potassium checked within the first year. Potassium >5 and >5.5 mmol/L
occurred in 5.6% and 1.7%, respectively. As a comparison, we propensity-matched
new ACE-I/ARB users to 20 186 new ?-blocker users in SCREAM: 64% had potassium
checked. The occurrence of elevated potassium levels was similar between new
?-blocker and ACE-I/ARB users without kidney disease; only at estimated
glomerular filtration rate <60 mL/min per 1.73 m(2) were risks higher among
ACE-I/ARB users. We developed a hyperkalemia susceptibility score that
incorporated estimated glomerular filtration rate, baseline potassium level, sex,
diabetes mellitus, heart failure, and the concomitant use of potassium-sparing
diuretics in new ACE-I/ARB users; this score accurately predicted 1-year
hyperkalemia risk in the SCREAM cohort (area under the curve, 0.845, 95% CI:
0.840-0.869) and in a validation cohort from the US-based Geisinger Health System
(N=19 524; area under the curve, 0.818, 95% CI: 0.794-0.841), with good
calibration. CONCLUSIONS: Hyperkalemia within the first year of ACE-I/ARB therapy
was relatively uncommon among people with estimated glomerular filtration rate
>60 mL/min per 1.73 m(2), but rates were much higher with lower estimated
glomerular filtration rate. Use of the hyperkalemia susceptibility score may help
guide laboratory monitoring and prescribing strategies.
