Nicardipine Associated Risk of Short-Term Mortality in Critically Ill Patients with Ischemic Stroke.J Stroke Cerebrovasc Dis. 2019 May; 28(5):1168-1172.JS
Hypertensive emergency is commonly associated with acute ischemic stroke and can be a predictor of poor outcome in these patients. Nicardipine and labetalol are commonly administered for the treatment of acute hypertension following stroke. Yet, data are lacking on the safety of these agents in this setting.
This study aimed to determine all-cause in-hospital mortality, medication-related hypotensive episodes, development of hospital acquired infections and hospital length of stay between nicardipine and labetalol use for the management of hypertension after acute ischemic stroke.
This retrospective study used a prospective database of individuals admitted to the neurointensive care unit at a university-based hospital over 39 months. Patients with confirmed ischemic strokes were included in this analysis. Data were recorded for administration of nicardipine and labetalol following acute stroke.
A total of 244 patients with acute ischemic stroke were included in this analysis (mean age, 64.3 ± 15 years; 52.2% males). Nicardipine use after acute ischemic stroke was associated with an increased risk of 30-day mortality (odds ratio [OR]: 4.6, 95% confidence interval [CI] 1.3-15.7; P = .02). A single episode of hypotension in the first 72hours of admission was also significantly associated with mortality (OR 4.35 [95% CI 1.2-14.9]; P = .02).
Nicardipine was associated with an increased risk of short-term mortality after acute ischemic stroke. This may have been due to hypotension, tachycardia, or pulmonary edema which were not apparent in our study. Further studies are required to elucidate the cause of this association.
