PURPOSE: To understand the hemodynamic effect of angiotensin II as a vasopressor in patients with shock secondary to COVID-19 infection.
METHODS: A retrospective analysis was performed on all patients at a single center with COVID-19 infection and shock who were treated with angiotensin II. The hemodynamic response to angiotensin II was estimated by recording the mean arterial pressure, norepinephrine equivalent dose (NED) and urine output.
RESULTS: Ten patients with COVID-19 related shock were treated with angiotensin II. Over the initial 6 hours, the average the norepinephrine equivalent dose decreased by 30.4% (from 64.6 mcg/min to 44 mcg/min) without a significant change in the mean arterial pressure (0.7% decrease). Six patients experienced at least a 25% reduction in norepinephrine equivalent dose by 6 hours, and two experienced at least a 50% reduction.
CONCLUSIONS: On average, the hemodynamic response to angiotensin II in COVID-19 related shock was favorable. Two patients had a marked rapid improvement. Given the relationship of SARS-CoV-2 with the renin angiotensin aldosterone system, further evaluation of angiotensin II for the treatment of COVID-19 related shock is warranted.
